+ *
+ * This example source code introduces a c library buffered I/O interface to
+ * URL reads it supports fopen(), fread(), fgets(), feof(), fclose(),
+ * rewind(). Supported functions have identical prototypes to their normal c
+ * lib namesakes and are preceaded by url_ .
+ *
+ * Using this code you can replace your program's fopen() with url_fopen()
+ * and fread() with url_fread() and it become possible to read remote streams
+ * instead of (only) local files. Local files (ie those that can be directly
+ * fopened) will drop back to using the underlying clib implementations
+ *
+ * See the main() function at the bottom that shows an app that retrives from a
+ * specified url using fgets() and fread() and saves as two output files.

+ * Implements an fopen() abstraction allowing reading from URLs
+ *
+ * This file introduces a c library buffered I/O interface to
+ * URL reads it supports fopen(), fread(), fgets(), feof(), fclose(),
+ * rewind(). Supported functions have identical prototypes to their normal c
+ * lib namesakes and are preceaded by a .
+ *
+ * Using this code you can replace your program's fopen() with afopen()
+ * and fread() with afread() and it become possible to read remote streams
+ * instead of (only) local files. Local files (ie those that can be directly
+ * fopened) will drop back to using the underlying clib implementations
+ *
+ * This example requires libcurl 7.9.7 or later.

-* @{
-* @details
-*
-* This is the driver API for the AXI DMA engine.
-*
-* For a full description of DMA features, please see the hardware spec. This
-* driver supports the following features:
-*
-*   - Scatter-Gather DMA (SGDMA)
-*   - Simple DMA
-*   - Interrupts
-*   - Programmable interrupt coalescing for SGDMA
-*   - APIs to manage Buffer Descriptors (BD) movement to and from the SGDMA
-*     engine
-*
-* <b>Simple DMA</b>
-*
-* Simple DMA allows the application to define a single transaction between DMA
-* and Device. It has two channels: one from the DMA to Device and the other
-* from Device to DMA. Application has to set the buffer address and
-* length fields to initiate the transfer in respective channel.
-*
-* <b>Transactions</b>
-*
-* The object used to describe a transaction is referred to as a Buffer
-* Descriptor (BD). Buffer descriptors are allocated in the user application.
-* The user application needs to set buffer address, transfer length, and
-* control information for this transfer. The control information includes
-* SOF and EOF. Definition of those masks are in xaxidma_hw.h
-*
-* <b>Scatter-Gather DMA</b>
-*
-* SGDMA allows the application to define a list of transactions in memory which
-* the hardware will process without further application intervention. During
-* this time, the application is free to continue adding more work to keep the
-* Hardware busy.
-*
-* User can check for the completion of transactions through polling the
-* hardware, or interrupts.
-*
-* SGDMA processes whole packets. A packet is defined as a series of
-* data bytes that represent a message. SGDMA allows a packet of data to be
-* broken up into one or more transactions. For example, take an Ethernet IP
-* packet which consists of a 14 byte header followed by a 1 or more bytes of
-* payload. With SGDMA, the application may point a BD to the header and another
-* BD to the payload, then transfer them as a single message. This strategy can
-* make a TCP/IP stack more efficient by allowing it to keep packet header and
-* data in different memory regions instead of assembling packets into
-* contiguous blocks of memory.
-*
-* <b>BD Ring Management</b>
-*
-* BD rings are shared by the software and the hardware.
-*
-* The hardware expects BDs to be setup as a linked list. The DMA hardware walks
-* through the list by following the next pointer field of a completed BD.
-* The hardware stops processing when the just completed BD is the same as the
-* BD specified in the Tail Ptr register in the hardware.
-*
-* The last BD in the ring is linked to the first BD in the ring.
-*
-* All BD management are done inside the driver. The user application should not
-* directly modify the BD fields. Modifications to the BD fields should always
-* go through the specific API functions.
-*
-* Within the ring, the driver maintains four groups of BDs. Each group consists
-* of 0 or more adjacent BDs:
-*
-*   - Free: The BDs that can be allocated by the application with
-*     XAxiDma_BdRingAlloc().
-*
-*   - Pre-process: The BDs that have been allocated with
-*     XAxiDma_BdRingAlloc(). These BDs are under application control. The
-*     application modifies these BDs through driver API to prepare them
-*     for DMA transactions.
-*
-*   - Hardware: The BDs that have been enqueued to hardware with
-*     XAxiDma_BdRingToHw(). These BDs are under hardware control and may be in a
-*     state of awaiting hardware processing, in process, or processed by
-*     hardware. It is considered an error for the application to change BDs
-*     while they are in this group. Doing so can cause data corruption and lead
-*     to system instability.
-*
-*   - Post-process: The BDs that have been processed by hardware and have
-*     been extracted from the Hardware group with XAxiDma_BdRingFromHw().
-*     These BDs are under application control. The application can check the
-*     transfer status of these BDs. The application use XAxiDma_BdRingFree()
-*     to put them into the Free group.
-*
-* BDs are expected to transition in the following way for continuous
-* DMA transfers:
-* <pre>
-*
-*         XAxiDma_BdRingAlloc()                   XAxiDma_BdRingToHw()
-*   Free ------------------------> Pre-process ----------------------> Hardware
-*                                                                      |
-*    /|\                                                               |
-*     |   XAxiDma_BdRingFree()                  XAxiDma_BdRingFromHw() |
-*     +--------------------------- Post-process <----------------------+
-*
-* </pre>
-*
-* When a DMA transfer is to be cancelled before enqueuing to hardware,
-* application can return the requested BDs to the Free group using
-* XAxiDma_BdRingUnAlloc(), as shown below:
-* <pre>
-*
-*         XAxiDma_BdRingUnAlloc()
-*   Free <----------------------- Pre-process
-*
-* </pre>
-*
-* The API provides functions for BD list traversal:
-* - XAxiDma_BdRingNext()
-* - XAxiDma_BdRingPrev()
-*
-* These functions should be used with care as they do not understand where
-* one group ends and another begins.
-*
-* <b>SGDMA Descriptor Ring Creation</b>
-*
-* BD ring is created using XAxiDma_BdRingCreate(). The memory for the BD ring
-* is allocated by the application, and it has to be contiguous. Physical
-* address is required to setup the BD ring.
-*
-* The applicaiton can use XAxiDma_BdRingMemCalc() to find out the amount of
-* memory needed for a certain number of BDs. XAxiDma_BdRingCntCalc() can be
-* used to find out how many BDs can be allocated for certain amount of memory.
-*
-* A helper function, XAxiDma_BdRingClone(), can speed up the BD ring setup if
-* the BDs have same types of controls, for example, SOF and EOF. After
-* using the XAxiDma_BdRingClone(), the application only needs to setup the
-* buffer address and transfer length. Note that certain BDs in one packet,
-* for example, the first BD and the last BD, may need to setup special
-* control information.
-*
-* <b>Descriptor Ring State Machine</b>
-*
-* There are two states of the BD ring:
-*
-*   - HALTED (H), where hardware is not running
-*
-*   - NOT HALTED (NH), where hardware is running
-*
-* The following diagram shows the state transition for the DMA engine:
-*
-* <pre>
-*   _____ XAxiDma_StartBdRingHw(), or XAxiDma_BdRingStart(),   ______
-*   |   |               or XAxiDma_Resume()                    |    |
-*   | H |----------------------------------------------------->| NH |
-*   |   |<-----------------------------------------------------|    |
-*   -----   XAxiDma_Pause() or XAxiDma_Reset()                 ------
-* </pre>
-*
-* <b>Interrupt Coalescing</b>
-*
-* SGDMA provides control over the frequency of interrupts through interrupt
-* coalescing. The DMA engine provides two ways to tune the interrupt
-* coalescing:
-*
-* - The packet threshold counter. Interrupt will fire once the
-*   programmable number of packets have been processed by the engine.
-*
-* - The packet delay timer counter. Interrupt will fire once the
-*   programmable amount of time has passed after processing the last packet,
-*   and no new packets to process. Note that the interrupt will only fire if
-*   at least one packet has been processed.
-*
-* <b> Interrupt </b>
-*
-* Interrupts are handled by the user application. Each DMA channel has its own
-* interrupt ID. The driver provides APIs to enable/disable interrupt,
-* and tune the interrupt frequency regarding to packet processing frequency.
-*
-* <b> Software Initialization </b>
-*
-*
-* To use the Simple mode DMA engine for transfers, the following setup is
-* required:
-*
-* - DMA Initialization using XAxiDma_CfgInitialize() function. This step
-*   initializes a driver instance for the given DMA engine and resets the
-*   engine.
-*
-* - Enable interrupts if chosen to use interrupt mode. The application is
-*   responsible for setting up the interrupt system, which includes providing
-*   and connecting interrupt handlers and call back functions, before
-*   enabling the interrupts.
-*
-* - Set the buffer address and length field in respective channels to start
-*   the DMA transfer
-*
-* To use the SG mode DMA engine for transfers, the following setup are
-* required:
-*
-* - DMA Initialization using XAxiDma_CfgInitialize() function. This step
-*   initializes a driver instance for the given DMA engine and resets the
-*   engine.
-*
-* - BD Ring creation. A BD ring is needed per DMA channel and can be built by
-*   calling XAxiDma_BdRingCreate().
-*
-* - Enable interrupts if chose to use interrupt mode. The application is
-*   responsible for setting up the interrupt system, which includes providing
-*   and connecting interrupt handlers and call back functions, before
-*   enabling the interrupts.
-*
-* - Start a DMA transfer: Call XAxiDma_BdRingStart() to start a transfer for
-*   the first time or after a reset, and XAxiDma_BdRingToHw() if the channel
-*   is already started. Calling XAxiDma_BdRingToHw() when a DMA channel is not
-*   running will not put the BDs to the hardware, and the BDs will be processed
-*   later when the DMA channel is started through XAxiDma_BdRingStart().
-*
-* <b> How to start DMA transactions </b>
-*
-* The user application uses XAxiDma_BdRingToHw() to submit BDs to the hardware
-* to start DMA transfers.
-*
-* For both channels, if the DMA engine is currently stopped (using
-* XAxiDma_Pause()), the newly added BDs will be accepted but not processed
-* until the DMA engine is started, using XAxiDma_BdRingStart(), or resumed,
-* using XAxiDma_Resume().
-*
-* <b> Software Post-Processing on completed DMA transactions </b>
-*
-* If the interrupt system has been set up and the interrupts are enabled,
-* a DMA channels notifies the software about the completion of a transfer
-* through interrupts. Otherwise, the user application can poll for
-* completions of the BDs, using XAxiDma_BdRingFromHw() or
-* XAxiDma_BdHwCompleted().
-*
-* - Once BDs are finished by a channel, the application first needs to fetch
-*   them from the channel using XAxiDma_BdRingFromHw().
-*
-* - On the TX side, the application now could free the data buffers attached to
-*   those BDs as the data in the buffers has been transmitted.
-*
-* - On the RX side, the application now could use the received data in the
-*	buffers attached to those BDs.
-*
-* - For both channels, completed BDs need to be put back to the Free group
-*   using XAxiDma_BdRingFree(), so they can be used for future transactions.
-*
-* - On the RX side, it is the application's responsibility to have BDs ready
-*   to receive data at any time. Otherwise, the RX channel refuses to
-*   accept any data if it has no RX BDs.
-*
-* <b> Examples </b>
-*
-* We provide five examples to show how to use the driver API:
-* - One for SG interrupt mode (xaxidma_example_sg_intr.c), multiple BD/packets transfer
-* - One for SG polling mode (xaxidma_example_sg_poll.c), single BD transfer.
-* - One for SG polling mode (xaxidma_poll_multi_pkts.c), multiple BD/packets transfer
-* - One for simple polling mode (xaxidma_example_simple_poll.c)
-* - One for simple Interrupt mode (xaxidma_example_simple_intr.c)
-*
-* <b> Address Translation </b>
-*
-* All buffer addresses and BD addresses for the hardware are physical
-* addresses. The user application is responsible to provide physical buffer
-* address for the BD upon BD ring creation. The user application accesses BD
-* through its virtual addess. The driver maintains the address translation
-* between the physical and virtual address for BDs.
-*
-* <b> Cache Coherency </b>
-*
-* This driver expects all application buffers attached to BDs to be in cache
-* coherent memory. If cache is used in the system, buffers for transmit MUST
-* be flushed from the cache before passing the associated BD to this driver.
-* Buffers for receive MUST be invalidated before accessing the data.
-*
-* <b> Alignment </b>
-*
-* For BDs:
-*
-* Minimum alignment is defined by the constant XAXIDMA_BD_MINIMUM_ALIGNMENT.
-* This is the smallest alignment allowed by both hardware and software for them
-* to properly work.
-*
-* If the descriptor ring is to be placed in cached memory, alignment also MUST
-* be at least the processor's cache-line size. Otherwise, system instability
-* occurs. For alignment larger than the cache line size, multiple cache line
-* size alignment is required.
-*
-* Aside from the initial creation of the descriptor ring (see
-* XAxiDma_BdRingCreate()), there are no other run-time checks for proper
-* alignment of BDs.
-*
-* For application data buffers:
-*
-* Application data buffers may reside on any alignment if DRE is built into the
-* hardware. Otherwise, application data buffer must be word-aligned. The word
-* is defined by XPAR_AXIDMA_0_M_AXIS_MM2S_TDATA_WIDTH for transmit and
-* XPAR_AXIDMA_0_S_AXIS_S2MM_TDATA_WIDTH for receive.
-*
-* For scatter gather transfers that have more than one BDs in the chain of BDs,
-* Each BD transfer length must be multiple of word too. Otherwise, internal
-* error happens in the hardware.
-*
-* <b> Error Handling </b>
-*
-* The DMA engine will halt on all error conditions. It requires the software
-* to do a reset before it can start process new transfer requests.
-*
-* <b> Restart After Stopping </b>
-*
-* After the DMA engine has been stopped (through reset or reset after an error)
-* the software keeps track of the current BD pointer when reset happens, and
-* processing of BDs can be resumed through XAxiDma_BdRingStart().
-*
-* <b> Limitations </b>
-*
-* This driver does not have any mechanisms for mutual exclusion. It is up to
-* the application to provide this protection.
-*
-* <b> Hardware Defaults & Exclusive Use </b>
-*
-* After the initialization or reset, the DMA engine is in the following
-* default mode:
-* - All interrupts are disabled.
-*
-* - Interrupt coalescing counter is 1.
-*
-* - The DMA engine is not running (halted). Each DMA channel is started
-*   separately, using XAxiDma_StartBdRingHw() if no BDs are setup for transfer
-*   yet, or XAxiDma_BdRingStart() otherwise.
-*
-* The driver has exclusive use of the registers and BDs. All accesses to the
-* registers and BDs should go through the driver interface.
-*
-* <b> Debug Print </b>
-*
-* To see the debug print for the driver, please put "-DDEBUG" as the extra
-* compiler flags in software platform settings. Also comment out the line in
-* xdebug.h: "#undef DEBUG".
-*
-* <b>Changes From v1.00a</b>
-*
-* . We have changes return type for XAxiDma_BdSetBufAddr() from void to int
-* . We added XAxiDma_LookupConfig() so that user does not need to look for the
-* hardware settings anymore.

- * Buffer descriptor (BD) management API.
- *
- * <b> Buffer Descriptors </b>
- *
- * A BD defines a DMA transaction (see "Transaction" section in xaxidma.h).
- * All accesses to a BD go through this set of API.
- *
- * The XAxiDma_Bd structure defines a BD. The first XAXIDMA_BD_HW_NUM_BYTES
- * are shared between hardware and software.
- *
- * <b> Actual Transfer Length </b>
- *
- * The actual transfer length for receive could be smaller than the requested
- * transfer length. The hardware sets the actual transfer length in the
- * completed BD. The API to retrieve the actual transfer length is
- * XAxiDma_GetActualLength().
- *
- * <b> User IP words </b>
- *
- * There are 5 user IP words in each BD.
- *
- * If hardware does not have the StsCntrl stream built in, then these words
- * are not usable. Retrieving these words get a NULL pointer and setting
- * these words results an error.
- *
- * <b> Performance </b>
- *
- * BDs are typically in a non-cached memory space. Reducing the number of
- * I/O operations to BDs can improve overall performance of the DMA channel.

-* This is a guide on how to move from using the xlldma driver to use xaxidma
-* driver.
-*
-* <pre>
-* MODIFICATION HISTORY:
-*
-* Ver   Who  Date     Changes
-* ----- ---- -------- -------------------------------------------------------
-* 1.00a jz   05/18/10 First release
-* 2.00a jz   08/10/10 Second release, added in xaxidma_g.c, xaxidma_sinit.c,
-*                     updated tcl file, added xaxidma_porting_guide.h
-* 4.00a rkv  02/22/11 Added support for simple DMA mode
-* 6.00a srt  03/27/12 Added support for MCDMA mode
-* 7.00a srt  06/18/12 API calls are reverted back for backward compatibility.
-*
-* </pre>
-*
-* <b>Overview</b>
-*
-* The API for xaxidma driver is similar to xlldma driver. The prefix for the
-* API functions and structures is XAxiDma_ for the xaxidma driver.
-*
-* Due to hardware feature changes, signatures of some API functions are a
-* little bit different from the xlldma API functions.
-*
-* We present API functions:
-* - That only have prefix changes
-* - That have different return type
-* - That are new API functions
-* - That have been removed
-*
-* Note that data structures have different prefix of XAxiDma_. Those API
-* functions, that have data structures with prefix change, are considered as
-* prefix change.
-*

-* <b>API Functions That Are New API Functions</b>
-*
-* Now that the AXI DMA core is a standalone core, some new API are intrduced.
-* Some other functions are added due to hardware interface change, so to
-* replace old API functions.
-*
-* - XAxiDma_Config *XAxiDma_LookupConfig(u32 DeviceId);

-*
-* This is the main header file for Xilinx AXI4-Stream Switch Control Router
-* core. It is used for routing streams where masters in the system do not know
-* final destination address.
-*
-* <b>Core Features </b>
-*
-* For a full description of AXI4-Stream Switch Control Router, please see the
-* hardware specification.
-*
-* <b>Software Initialization & Configuration</b>
-*
-* The application needs to do following steps in order for preparing the
-* AXI4-Stream Switch Control Router core to be ready.
-*
-* - Call XAxisScr_LookupConfig using a device ID to find the core
-*   configuration.
-* - Call XAxisScr_CfgInitialize to initialize the device and the driver
-*   instance associated with it.
-*
-* <b>Interrupts </b>
-*
-* This driver does not have interrupt mechanism.
-*
-* <b> Virtual Memory </b>
-*
-* This driver supports Virtual Memory. The RTOS is responsible for calculating
-* the correct device base address in Virtual Memory space.
-*
-* <b> Threads </b>
-*
-* This driver is not thread safe. Any needs for threads or thread mutual
-* exclusion must be satisfied by the layer above this driver.
-*
-* <b> Asserts </b>
-*
-* Asserts are used within all Xilinx drivers to enforce constraints on argument
-* values. Asserts can be turned off on a system-wide basis by defining at
-* compile time, the NDEBUG identifier. By default, asserts are turned on and it
-* is recommended that users leave asserts on during development.
-*
-* <b> Building the driver </b>
-*
-* The XAXI4-Stream Switch driver is composed of several source files. This
-* allows the user to build and link only those parts of the driver that are
-* necessary.

-* @details
-*
-* The Xilinx interrupt controller driver component. This component supports the
-* Xilinx interrupt controller.
-*
-* The interrupt controller driver uses the idea of priority for the various
-* handlers. Priority is an integer within the range of 0 and 31 inclusive with
-* 0 being the highest priority interrupt source.
-*
-* The Xilinx interrupt controller supports the following features:
-*
-*   - specific individual interrupt enabling/disabling
-*   - specific individual interrupt acknowledging
-*   - attaching specific callback function to handle interrupt source
-*   - master enable/disable
-*   - single callback per interrupt or all pending interrupts handled for
-*     each interrupt of the processor
-*
-* The acknowledgement of the interrupt within the interrupt controller is
-* selectable, either prior to the device's handler being called or after
-* the handler is called. This is necessary to support interrupt signal inputs
-* which are either edge or level signals.  Edge driven interrupt signals
-* require that the interrupt is acknowledged prior to the interrupt being
-* serviced in order to prevent the loss of interrupts which are occurring
-* extremely close together.  A level driven interrupt input signal requires
-* the interrupt to acknowledged after servicing the interrupt to ensure that
-* the interrupt only generates a single interrupt condition.
-*
-* Details about connecting the interrupt handler of the driver are contained
-* in the source file specific to interrupt processing, xintc_intr.c.
-*
-* This driver is intended to be RTOS and processor independent.  It works with
-* physical addresses only.  Any needs for dynamic memory management, threads
-* or thread mutual exclusion, virtual memory, or cache control must be
-* satisfied by the layer above this driver.
-*
-* <b>Interrupt Vector Tables</b>
-*
-* The interrupt vector table for each interrupt controller device is declared
-* statically in xintc_g.c within the configuration data for each instance.
-* The device ID of the interrupt controller device is used by the driver as a
-* direct index into the configuration data table - to retrieve the vector table
-* for an instance of the interrupt controller. The user should populate the
-* vector table with handlers and callbacks at run-time using the XIntc_Connect()
-* and XIntc_Disconnect() functions.
-*
-* Each vector table entry corresponds to a device that can generate an
-* interrupt. Each entry contains an interrupt handler function and an argument
-* to be passed to the handler when an interrupt occurs.  The tools default this
-* argument to the base address of the interrupting device.  Note that the
-* device driver interrupt handlers given in this file do not take a base
-* address as an argument, but instead take a pointer to the driver instance.
-* This means that although the table is created statically, the user must still
-* use XIntc_Connect() when the interrupt handler takes an argument other than
-* the base address. This is only to say that the existence of the static vector
-* tables should not mislead the user into thinking they no longer need to
-* register/connect interrupt handlers with this driver.
-*
-* <pre>
-* MODIFICATION HISTORY:
-*
-* Ver   Who  Date     Changes
-* ----- ---- -------- -------------------------------------------------------
-* 1.00a ecm  08/16/01 First release
-* 1.00a rpm  01/09/02 Removed the AckLocation argument from XIntc_Connect().
-*                     This information is now internal in xintc_g.c.
-* 1.00b jhl  02/13/02 Repartitioned the driver for smaller files
-* 1.00b jhl  04/24/02 Made LookupConfig function global and relocated config
-*                     data type
-* 1.00c rpm  10/17/03 New release. Support the static vector table created
-*                     in the xintc_g.c configuration table. Moved vector
-*                     table and options out of instance structure and into
-*                     the configuration table.

-*		      and XIntc_SetNormalIntrMode for setting to normal
-*		      interrupt mode.
-* 2.04a asa  03/19/12 Changed the XIntc_Config struct. The order of entries
-*		      declared in the structure now matches with the
-*		      XIntc_ConfigTable generated by the driver tcl.
-* 2.05a bss  08/16/12 Updated to support relocatable vectors in Microblaze,
-*		      added IntVectorAddr to XIntc_Config for this.
-*		      Added XIntc_RegisterFastHandler API to register fast
-*		      interrupt handlers using base address.

-*		      API in xintc_l.c.
-*		      Modified XIntc_SetOptions API in xintc_options.c.
-*		      Modified XIntc_SimulateIntr API in xintc_selftest.c.
-*		      Modified driver tcl:
-*			to check for Cascade mode and generate XPAR_INTC_TYPE
-*			for each controller.
-*			Generate XPAR_INTC_MAX_NUM_INTR_INPUTS by adding all
-*			interrupt sources of all Controllers in Cascade mode.
-* 2.07a bss  10/18/13 To support Nested interrupts:

-*		      correctly(CR#764865).
-*
-* @note
-*		For Cascade mode, Interrupt IDs are generated in xparameters.h
-*		as shown below:
-*
-*	    Master/Primary INTC
-*		 ______
-*		|      |-0      Secondary INTC
-*		|      |-.         ______
-*		|      |-.        |      |-32        Last INTC
-*		|      |-.        |      |-.          ______
-*		|______|<-31------|      |-.         |      |-64
-*			          |      |-.         |      |-.
-*			          |______|<-63-------|      |-.
-*                                                    |      |-.
-*                                                    |______|-95
-*
-*		All driver functions has to be called using DeviceId/
-*		InstancePtr/BaseAddress of Primary/Master Controller and
-*		Interrupts IDs generated in xparameters.h only.
-*		Driver functions takes care of Slave Controllers based on
-*		Interrupt ID passed. User must not use Interrupt source/ID
-*		31 of Primary and Secondary controllers to call driver
-*		functions.
-*
-*		For nested interrupts, XIntc_DeviceInterruptHandler saves
-*		microblaze r14 register on entry and restores on exit. This is
-*		required since compiler does not support nesting. It enables
-*		Microblaze interrupts after blocking further interrupts from
-*		the current interrupt number and interrupts below current
-*		interrupt proirity by writing to Interrupt Level Register of
-*		INTC on entry. On exit, it disables microblaze interrupts and
-*		restores ILR register default value(0xFFFFFFFF)back. It is
-*		recommended to increase STACK_SIZE in linker script for nested
-*		interrupts.
-* 3.0     adk    12/10/13  Updated as per the New Tcl API's
-* 3.0 	  adk 	 17/02/14  Fixed the CR:771287 Changes are made in the intc
-* 		           driver tcl.
-* 3.1     adk    8/4/14    Fixed the CR:783248 Changes are made in
-*			   the test-app tcl
-* 3.2     bss    4/8/14    Fixed driver tcl to handle external interrupt pins
-*			   correctly (CR#799609).
-* 3.3     adk    11/3/14   added generation of C_HAS_ILR parameter to
-*			   xparameters.h.Changes are made in the driver tcl file
-*			   (CR#828046).

-* an interrupt handler dynamically (at run-time) using the
-* XIntc_RegisterHandler() function.
-* User of the driver interface given in xintc.h should still use
-* XIntc_Connect(), as always.
-* Also see the discussion of the interrupt vector tables in xintc.h.
-*
-* There are currently two interrupt handlers specified in this interface.
-*
-* - XIntc_LowLevelInterruptHandler() is a handler without any arguments that
-*   is used in cases where there is a single interrupt controller device in
-*   the system and the handler cannot be passed an argument. This function is
-*   provided mostly for backward compatibility.
-*
-* - XIntc_DeviceInterruptHandler() is a handler that takes a device ID as an
-*   argument, indicating which interrupt controller device in the system is
-*   causing the interrupt - thereby supporting multiple interrupt controllers.

-* @details
- *
- * The Xilinx Dual Channel Fifo driver component. This driver supports the
- * Virtex-5(TM) and Virtex-4(TM) XPS_ll_Fifo and the AxiFifo.
- *
- * For a full description of the bridge features, please see the HW spec. This
- * driver supports the following features:
- *   - Memory mapped access to host interface registers
- *   - API for polled frame transfers
- *   - API for interrupt driven frame transfers
- *   - Virtual memory support
- *   - Full duplex operation
- *
- * <h2>Driver Description</h2>
- *
- * This driver enables higher layer software to access the XPS_llFifo core
- * using any alignment in the data buffers.
- *
- * This driver supports send and receive channels in the same instance
- * structure in the same fashion as the hardware core.
- *
- * <h2>Initialization</h2>
- *
- * An instance of this driver is initialized using a call to Initialize().
- *
- * <h2>Usage</h2>
- *
- * It is fairly simple to use the API provided by this FIFO driver. The
- * only somewhat tricky part is that the calling code must correctly call
- * a couple routines in the right sequence for receive and transmit.
- *
- * This sequence is described here. Check the routine functional
- * descriptions for information on how to use a specific API routine.
- *
- * <h3>Receive</h3>
- *
- * A frame is received by using the following sequence:<br>
- * 1) call XLlFifo_RxOccupancy() to check the occupancy count<br>
- * 2) call XLlFifo_RxGetLen() to get the length of the next incoming frame<br>
- * 3) call XLlFifo_Read() one or more times to read the number of bytes
- *    reported by XLlFifo_RxGetLen().<br>
- *
- * For example:
- * <pre>
- * 	while (XLlFifo_RxOccupancy(&RxInstance)) {
- * 		frame_len = XLlFifo_RxGetLen(&RxInstance);
- *		while (frame_len) {
- * 			unsigned bytes = min(sizeof(buffer), frame_len);
- * 			XLlFifo_Read(&RxInstance, buffer, bytes);
- * 			// ********
- * 			// do something with buffer here
- * 			// ********
- * 			frame_len -= bytes;
- *		}
- * 	}
- * </pre>
- *
- * This FIFO hardware core does <b>not</b> support a sequence where the
- * calling code calls RxGetLen() twice in a row and then receive the data
- * for two frames. Each frame must be read in by calling RxGetLen() just
- * prior to reading the data.
- *
- * <h3>Transmit</h3>
- * A frame is transmittted by using the following sequence:<br>
- * 1) call XLlFifo_Write() one or more times to write all the of bytes in
- *    the next frame.<br>
- * 2) call XLlFifo_TxSetLen() to begin the transmission of frame just
- *    written.<br>
- *
- * For example:
- * <pre>
- * 	frame_left = frame_len;
- * 	while (frame_left) {
- * 		unsigned bytes = min(sizeof(buffer), frame_left);
- * 		XLlFifo_Write(&TxInstance, buffer, bytes);
- * 		// ********
- * 		// do something here to refill buffer
- * 		// ********
- * 		frame_left -= bytes;
- * 	}
- * 	XLlFifo_TxSetLen(&RxInstance, frame_len);
- * </pre>
- *
- * This FIFO hardware core does <b>not</b> support a sequence where the
- * calling code writes the data for two frames and then calls TxSetLen()
- * twice in a row. Each frame must be written by writting the data for one
- * frame and then calling TxSetLen().
- *
- * <h2>Interrupts</h2>
- * This driver does not handle interrupts from the FIFO hardware. The
- * software layer above may make use of the interrupts by setting up its
- * own handlers for the interrupts.
- *
- * <pre>
- * MODIFICATION HISTORY:
- *
- * Ver   Who  Date     Changes
- * ----- ---- -------- -------------------------------------------------------
- * 1.00a jvb  10/12/06 First release
- * 1.01a sdm  08/22/08 Removed support for static interrupt handlers from the
- *		       MDD file
- * 1.02a jz   12/04/09 Hal phase 1 support
- * 2.01a asa  09/17/10 Added code for resetting Local Link/AXI Streaming
- *		       interface for CR574868
- * 2.02a asa  12/27/11 Changed the function XStrm_Read in xtreamer.c to reset
- *		       HeadIndex to zero when all bytes have been read.
- *		       Changed the macro XStrm_IsRxInternalEmpty in file
- *		       xtreamer.h to use FrmByteCnt instead of HeadIndex.
- *		       When FrmByteCnt is zero, this means all internal buffers
- *		       in streamer are empty. Earlier implementation using
- *		       HeadIndex was not very clear and could give improper
- *		       results for some cases.
- *		       Changed the macro XLlFifo_IsRxEmpty in file xllfifo.h
- *		       These changes are done to fix the CR 604650.
-  * 2.03a asa  14/08/12  Added XLLF_TDR_OFFSET, XLLF_RDR_OFFSET
- *		         defines for the new registers, and XLLF_INT_TFPF_MASK,
- *		         XLLF_INT_TFPE_MASK, XLLF_INT_RFPF_MASK and
- *		         XLLF_INT_RFPE_MASK for the new version of the
- *		         AXI4-Stream FIFO core (v2.01a and later)
- *
- * 3.00a adk 08/10/13 Added support for AXI4 Datainterface.Changes are
- * 		      In Xllfifo.c file XLlFifo_RxGetWord,XLlFifo_TxPutword.
- * 		      In XLlfifo.h file updated XLlfifo structure for
- * 		      Axi4BaseAddress and for Datainterface type provided
- *		      polling and interrupt examples. XLlfifo_IsRxDone Macro
- *		      Is added in the XLlfifo.h file for polledmode exmaple.
- *		      Added Static initialzation for the driver.
- *		      XLlFifo_Initialize is still used to make the driver
- *		      backward compatible.
- * 4.0   adk  19/12/13 Updated as per the New Tcl API's
- * 5.0   adk  15/05/15 Updated the register offsets in the AXI4 data path
- *		       as per latest IP version(v4.1)(CR:860254).

-* @{
- *
- * The Xilinx byte streamer for packet FIFOs.
- *
- * <h2>Driver Description</h2>
- *
- * This driver enables higher layer software to access a hardware FIFO using
- * any alignment in the data buffers while preserving alignment for the hardware
- * FIFO access.
- *
- * This driver treats send and receive channels separately, using different
- * types of instance objects for each.
- *
- * This driver makes use of another FIFO driver to access the specific FIFO
- * hardware through use of the routines passed into the Tx/RxInitialize
- * routines.
- *
- * <h2>Initialization</h2>
- *
- * Send and receive channels are intialized separately. The receive channel is
- * initiailzed using XStrm_RxInitialize(). The send channel is initialized
- * using XStrm_TxInitialize().
- *
- *
- * <h2>Usage</h2>
- * It is fairly simple to use the API provided by this byte streamer
- * driver. The only somewhat tricky part is that the calling code must
- * correctly call a couple routines in the right sequence for receive and
- * transmit.
- *
- * 	This sequence is described here. Check the routine functional
- * descriptions for information on how to use a specific API routine.
- *
- * <h3>Receive</h3>
- * A frame is received by using the following sequence:<br>
- * 1) call XStrm_RxGetLen() to get the length of the next incoming frame.<br>
- * 2) call XStrm_Read() one or more times to read the number of bytes
- * 	   reported by XStrm_RxGetLen().<br>
- *
- * For example:
- * <pre>
- * 	frame_len = XStrm_RxGetLen(&RxInstance);
- * 	while (frame_len) {
- * 		unsigned bytes = min(sizeof(buffer), frame_len);
- * 		XStrm_Read(&RxInstance, buffer, bytes);
- * 		// do something with buffer here
- * 		frame_len -= bytes;
- * 	}
- * </pre>
- *
- * Other restrictions on the sequence of API calls may apply depending on
- * the specific FIFO driver used by this byte streamer driver.
- *
- * <h3>Transmit</h3>
- * A frame is transmittted by using the following sequence:<br>
- * 1) call XStrm_Write() one or more times to write all the of bytes in
- *    the next frame.<br>
- * 2) call XStrm_TxSetLen() to begin the transmission of frame just
- *    written.<br>
- *
- * For example:
- * <pre>
- * 	frame_left = frame_len;
- * 	while (frame_left) {
- * 		unsigned bytes = min(sizeof(buffer), frame_left);
- * 		XStrm_Write(&TxInstance, buffer, bytes);
- * 		// do something here to refill buffer
- * 	}
- * 	XStrm_TxSetLen(&RxInstance, frame_len);
- * </pre>
- *
- * Other restrictions on the sequence of API calls may apply depending on
- * the specific FIFO driver used by this byte streamer driver.
- *
- * <pre>
- * MODIFICATION HISTORY:
- *
- * Ver   Who  Date     Changes
- * ----- ---- -------- -------------------------------------------------------

- * 1.02a jz   12/04/09  Hal phase 1 support
- * 2.00a hbm  01/20/10  Hal phase 1 support, bump up major release

-* The Xilinx timer/counter component. This component supports the Xilinx
-* timer/counter. More detailed description of the driver operation can
-* be found in the xtmrctr.c file.
-*
-* The Xilinx timer/counter supports the following features:
-*   - Polled mode.
-*   - Interrupt driven mode
-*   - enabling and disabling specific timers
-*   - PWM operation
-*   - Cascade Operation (This is to be used for getting a 64 bit timer and this
-*     feature is present in the latest versions of the axi_timer IP)
-*
-* The driver does not currently support the PWM operation of the device.
-*
-* The timer counter operates in 2 primary modes, compare and capture. In
-* either mode, the timer counter may count up or down, with up being the
-* default.
-*
-* Compare mode is typically used for creating a single time period or multiple
-* repeating time periods in the auto reload mode, such as a periodic interrupt.
-* When started, the timer counter loads an initial value, referred to as the
-* compare value, into the timer counter and starts counting down or up. The
-* timer counter expires when it rolls over/under depending upon the mode of
-* counting. An external compare output signal may be configured such that a
-* pulse is generated with this signal when it hits the compare value.
-*
-* Capture mode is typically used for measuring the time period between
-* external events. This mode uses an external capture input signal to cause
-* the value of the timer counter to be captured. When started, the timer
-* counter loads an initial value, referred to as the compare value,
-
-* The timer can be configured to either cause an interrupt when the count
-* reaches the compare value in compare mode or latch the current count
-* value in the capture register when an external input is asserted
-* in capture mode. The external capture input can be enabled/disabled using the
-* XTmrCtr_SetOptions function. While in compare mode, it is also possible to
-* drive an external output when the compare value is reached in the count
-* register The external compare output can be enabled/disabled using the
-* XTmrCtr_SetOptions function.
-*
-* <b>Interrupts</b>
-*
-* It is the responsibility of the application to connect the interrupt
-* handler of the timer/counter to the interrupt source. The interrupt
-* handler function, XTmrCtr_InterruptHandler, is visible such that the user
-* can connect it to the interrupt source. Note that this interrupt handler
-* does not provide interrupt context save and restore processing, the user
-* must perform this processing.
-*
-* The driver services interrupts and passes timeouts to the upper layer
-* software through callback functions. The upper layer software must register
-* its callback functions during initialization. The driver requires callback
-* functions for timers.
-*
-* @note
-* The default settings for the timers are:
-*   - Interrupt generation disabled
-*   - Count up mode
-*   - Compare mode
-*   - Hold counter (will not reload the timer)
-*   - External compare output disabled
-*   - External capture input disabled
-*   - Pulse width modulation disabled
-*   - Timer disabled, waits for Start function to be called
-* <br><br>
-* A timer counter device may contain multiple timer counters. The symbol
-* XTC_DEVICE_TIMER_COUNT defines the number of timer counters in the device.
-* The device currently contains 2 timer counters.
-* <br><br>
-* This driver is intended to be RTOS and processor independent. It works with
-* physical addresses only. Any needs for dynamic memory management, threads
-* or thread mutual exclusion, virtual memory, or cache control must be
-* satisfied by the layer above this driver.
-*
-* <pre>
-* MODIFICATION HISTORY:
-*
-* Ver   Who  Date     Changes
-* ----- ---- -------- -----------------------------------------------
-* 1.00a ecm  08/16/01 First release
-* 1.00b jhl  02/21/02 Repartitioned the driver for smaller files
-* 1.10b mta  03/21/07 Updated to new coding style.
-* 1.11a sdm  08/22/08 Removed support for static interrupt handlers from the MDD
-*		      file
-* 2.00a ktn  10/30/09 Updated to use HAL API's. _m is removed from all the macro
-*		      definitions.
-* 2.01a ktn  07/12/10 Renamed the macro XTimerCtr_ReadReg as XTmrCtr_ReadReg
-*		      for naming consistency (CR 559142).
-* 2.02a sdm  09/28/10 Updated the driver tcl to generate the xparameters
-*		      for the timer clock frequency (CR 572679).
-* 2.03a rvo  11/30/10 Added check to see if interrupt is enabled before further
-*		      processing for CR 584557.
-* 2.04a sdm  07/12/11 Added support for cascade mode operation.
-* 		      The cascade mode of operation is present in the latest
-*		      versions of the axi_timer IP. Please check the HW
-*		      Datasheet to see whether this feature is present in the
-*		      version of the IP that you are using.
-* 2.05a adk  15/05/13 Fixed the CR:693066
-*		      Added the IsStartedTmrCtr0/IsStartedTmrCtr1 members to the
-*		      XTmrCtr instance structure.
-*		      The IsStartedTmrCtrX will be assigned XIL_COMPONENT_IS_STARTED in
-*		      the XTmrCtr_Start function.
-*		      The IsStartedTmrCtrX will be cleared in the XTmrCtr_Stop function.
-*		      There will be no Initialization done in the
-*		      XTmrCtr_Initialize if both the timers have already started and
-*		      the XST_DEVICE_IS_STARTED Status is returned.
-*		      Removed the logic in the XTmrCtr_Initialize function
-*		      which was checking the Register Value to know whether
-*		      a timer has started or not.
-* 3.0   adk  19/12/13 Updated as per the New Tcl API's
-* 4.0   als  09/30/15 Updated initialization API.

-*
-* This file contains utility functions such as memory test functions.
-*
-* <b>Memory test description</b>
-*
-* A subset of the memory tests can be selected or all of the tests can be run
-* in order. If there is an error detected by a subtest, the test stops and the
-* failure code is returned. Further tests are not run even if all of the tests
-* are selected.
-*
-* Subtest descriptions:
-* <pre>
-* XUT_ALLMEMTESTS:
-*       Runs all of the following tests
-*
-* XUT_INCREMENT:
-*       Incrementing Value Test.
-*       This test starts at 'XUT_MEMTEST_INIT_VALUE' and uses the incrementing
-*       value as the test value for memory.
-*
-* XUT_WALKONES:
-*       Walking Ones Test.
-*       This test uses a walking '1' as the test value for memory.
-*       location 1 = 0x00000001
-*       location 2 = 0x00000002
-*       ...
-*
-* XUT_WALKZEROS:
-*       Walking Zero's Test.
-*       This test uses the inverse value of the walking ones test
-*       as the test value for memory.
-*       location 1 = 0xFFFFFFFE
-*       location 2 = 0xFFFFFFFD
-*       ...
-*
-* XUT_INVERSEADDR:
-*       Inverse Address Test.
-*       This test uses the inverse of the address of the location under test
-*       as the test value for memory.
-*
-* XUT_FIXEDPATTERN:
-*       Fixed Pattern Test.
-*       This test uses the provided patters as the test value for memory.
-*       If zero is provided as the pattern the test uses '0xDEADBEEF".
-* </pre>
-*
-* <i>WARNING</i>
-*
-* The tests are <b>DESTRUCTIVE</b>. Run before any initialized memory spaces
-* have been set up.
-*
-* The address, Addr, provided to the memory tests is not checked for
-* validity except for the NULL case. It is possible to provide a code-space
-* pointer for this test to start with and ultimately destroy executable code
-* causing random failures.
-*
-* @note
-*
-* Used for spaces where the address range of the region is smaller than
-* the data width. If the memory range is greater than 2 ** width,
-* the patterns used in XUT_WALKONES and XUT_WALKZEROS will repeat on a
-* boundry of a power of two making it more difficult to detect addressing
-* errors. The XUT_INCREMENT and XUT_INVERSEADDR tests suffer the same
-* problem. Ideally, if large blocks of memory are to be tested, break
-* them up into smaller regions of memory to allow the test patterns used
-* not to repeat over the region tested.
-*
-* <pre>
-* MODIFICATION HISTORY:

-<div class="textblock"><p>This is the driver API for the AXI DMA engine.For a full description of DMA features, please see the hardware spec. This driver supports the following features:</p>
-<ul>
-<li>Scatter-Gather DMA (SGDMA)</li>
-<li>Simple DMA</li>
-<li>Interrupts</li>
-<li>Programmable interrupt coalescing for SGDMA</li>
-<li>APIs to manage Buffer Descriptors (BD) movement to and from the SGDMA engine</li>
-</ul>
-<p><b>Simple DMA</b></p>
-<p>Simple DMA allows the application to define a single transaction between DMA and Device. It has two channels: one from the DMA to Device and the other from Device to DMA. Application has to set the buffer address and length fields to initiate the transfer in respective channel.</p>
-<p><b>Transactions</b></p>
-<p>The object used to describe a transaction is referred to as a Buffer Descriptor (BD). Buffer descriptors are allocated in the user application. The user application needs to set buffer address, transfer length, and control information for this transfer. The control information includes SOF and EOF. Definition of those masks are in <a class="el" href="xaxidma__hw_8h.html">xaxidma_hw.h</a></p>
-<p><b>Scatter-Gather DMA</b></p>
-<p>SGDMA allows the application to define a list of transactions in memory which the hardware will process without further application intervention. During this time, the application is free to continue adding more work to keep the Hardware busy.</p>
-<p>User can check for the completion of transactions through polling the hardware, or interrupts.</p>
-<p>SGDMA processes whole packets. A packet is defined as a series of data bytes that represent a message. SGDMA allows a packet of data to be broken up into one or more transactions. For example, take an Ethernet IP packet which consists of a 14 byte header followed by a 1 or more bytes of payload. With SGDMA, the application may point a BD to the header and another BD to the payload, then transfer them as a single message. This strategy can make a TCP/IP stack more efficient by allowing it to keep packet header and data in different memory regions instead of assembling packets into contiguous blocks of memory.</p>
-<p><b>BD Ring Management</b></p>
-<p>BD rings are shared by the software and the hardware.</p>
-<p>The hardware expects BDs to be setup as a linked list. The DMA hardware walks through the list by following the next pointer field of a completed BD. The hardware stops processing when the just completed BD is the same as the BD specified in the Tail Ptr register in the hardware.</p>
-<p>The last BD in the ring is linked to the first BD in the ring.</p>
-<p>All BD management are done inside the driver. The user application should not directly modify the BD fields. Modifications to the BD fields should always go through the specific API functions.</p>
-<p>Within the ring, the driver maintains four groups of BDs. Each group consists of 0 or more adjacent BDs:</p>
-<ul>
-<li>Free: The BDs that can be allocated by the application with <a class="el" href="group__axidma__v9__0.html#ga44003cd704b7d4868d1dc00bb433a91f" title="Reserve locations in the BD ring. ">XAxiDma_BdRingAlloc()</a>.</li>
-<li>Pre-process: The BDs that have been allocated with <a class="el" href="group__axidma__v9__0.html#ga44003cd704b7d4868d1dc00bb433a91f" title="Reserve locations in the BD ring. ">XAxiDma_BdRingAlloc()</a>. These BDs are under application control. The application modifies these BDs through driver API to prepare them for DMA transactions.</li>
-<li>Hardware: The BDs that have been enqueued to hardware with <a class="el" href="group__axidma__v9__0.html#gaac81111b373e373be7dd3989fffffe7b" title="Enqueue a set of BDs to hardware that were previously allocated by XAxiDma_BdRingAlloc(). ">XAxiDma_BdRingToHw()</a>. These BDs are under hardware control and may be in a state of awaiting hardware processing, in process, or processed by hardware. It is considered an error for the application to change BDs while they are in this group. Doing so can cause data corruption and lead to system instability.</li>
-<li>Post-process: The BDs that have been processed by hardware and have been extracted from the Hardware group with <a class="el" href="group__axidma__v9__0.html#ga1e5d328b4d4a247d1530fac3efe4c59c" title="Returns a set of BD(s) that have been processed by hardware.

-</pre><p><b>Interrupt Coalescing</b></p>
-<p>SGDMA provides control over the frequency of interrupts through interrupt coalescing. The DMA engine provides two ways to tune the interrupt coalescing:</p>
-<ul>
-<li>The packet threshold counter. Interrupt will fire once the programmable number of packets have been processed by the engine.</li>
-<li>The packet delay timer counter. Interrupt will fire once the programmable amount of time has passed after processing the last packet, and no new packets to process. Note that the interrupt will only fire if at least one packet has been processed.</li>
-</ul>
-<p><b> Interrupt </b></p>
-<p>Interrupts are handled by the user application. Each DMA channel has its own interrupt ID. The driver provides APIs to enable/disable interrupt, and tune the interrupt frequency regarding to packet processing frequency.</p>
-<p><b> Software Initialization </b></p>
-<p>To use the Simple mode DMA engine for transfers, the following setup is required:</p>
-<ul>
-<li>DMA Initialization using <a class="el" href="group__axidma__v9__0.html#ga8026e76c90d891d21c9c355ff776cb77" title="This function initializes a DMA engine. ">XAxiDma_CfgInitialize()</a> function. This step initializes a driver instance for the given DMA engine and resets the engine.</li>
-<li>Enable interrupts if chosen to use interrupt mode. The application is responsible for setting up the interrupt system, which includes providing and connecting interrupt handlers and call back functions, before enabling the interrupts.</li>
-<li>Set the buffer address and length field in respective channels to start the DMA transfer</li>
-</ul>
-<p>To use the SG mode DMA engine for transfers, the following setup are required:</p>
-<ul>

-<li>BD Ring creation. A BD ring is needed per DMA channel and can be built by calling <a class="el" href="group__axidma__v9__0.html#ga5c6d6f492642dd355478c3a853556d6b" title="Using a memory segment allocated by the caller, This fundtion creates and setup the BD ring...">XAxiDma_BdRingCreate()</a>.</li>

-</ul>
-<p><b> How to start DMA transactions </b></p>
-<p>The user application uses <a class="el" href="group__axidma__v9__0.html#gaac81111b373e373be7dd3989fffffe7b" title="Enqueue a set of BDs to hardware that were previously allocated by XAxiDma_BdRingAlloc(). ">XAxiDma_BdRingToHw()</a> to submit BDs to the hardware to start DMA transfers.</p>
-<p>For both channels, if the DMA engine is currently stopped (using <a class="el" href="group__axidma__v9__0.html#gadb572b623215a7df62b1e0468e3bd68c" title="Pause DMA transactions on both channels. ">XAxiDma_Pause()</a>), the newly added BDs will be accepted but not processed until the DMA engine is started, using <a class="el" href="group__axidma__v9__0.html#gaafd18a1df185c30b4745c147e3295ac3" title="Start a DMA channel, updates current descriptors and Allow DMA transactions to commence on a given ch...">XAxiDma_BdRingStart()</a>, or resumed, using <a class="el" href="group__axidma__v9__0.html#ga847cd9a0255fcb444bce58b945de8574" title="Resume DMA transactions on both channels. ">XAxiDma_Resume()</a>.</p>
-<p><b> Software Post-Processing on completed DMA transactions </b></p>
-<p>If the interrupt system has been set up and the interrupts are enabled, a DMA channels notifies the software about the completion of a transfer through interrupts. Otherwise, the user application can poll for completions of the BDs, using <a class="el" href="group__axidma__v9__0.html#ga1e5d328b4d4a247d1530fac3efe4c59c" title="Returns a set of BD(s) that have been processed by hardware.

">XAxiDma_BdHwCompleted()</a>.</p>
-<ul>
-<li>Once BDs are finished by a channel, the application first needs to fetch them from the channel using <a class="el" href="group__axidma__v9__0.html#ga1e5d328b4d4a247d1530fac3efe4c59c" title="Returns a set of BD(s) that have been processed by hardware. ">XAxiDma_BdRingFromHw()</a>.</li>
-<li>On the TX side, the application now could free the data buffers attached to those BDs as the data in the buffers has been transmitted.</li>
-<li>On the RX side, the application now could use the received data in the buffers attached to those BDs.</li>
-<li>For both channels, completed BDs need to be put back to the Free group using <a class="el" href="group__axidma__v9__0.html#gad2ac76e5a39486896cd484e51d2898c7" title="Frees a set of BDs that had been previously retrieved with XAxiDma_BdRingFromHw(). ">XAxiDma_BdRingFree()</a>, so they can be used for future transactions.</li>
-<li>On the RX side, it is the application's responsibility to have BDs ready to receive data at any time. Otherwise, the RX channel refuses to accept any data if it has no RX BDs.</li>
-</ul>
-<p><b> Examples </b></p>
-<p>We provide five examples to show how to use the driver API:</p><ul>
-<li>One for SG interrupt mode (xaxidma_example_sg_intr.c), multiple BD/packets transfer</li>
-<li>One for SG polling mode (xaxidma_example_sg_poll.c), single BD transfer.</li>
-<li>One for SG polling mode (xaxidma_poll_multi_pkts.c), multiple BD/packets transfer</li>
-<li>One for simple polling mode (xaxidma_example_simple_poll.c)</li>
-<li>One for simple Interrupt mode (xaxidma_example_simple_intr.c)</li>
-</ul>
-<p><b> Address Translation </b></p>
-<p>All buffer addresses and BD addresses for the hardware are physical addresses. The user application is responsible to provide physical buffer address for the BD upon BD ring creation. The user application accesses BD through its virtual addess. The driver maintains the address translation between the physical and virtual address for BDs.</p>
-<p><b> Cache Coherency </b></p>
-<p>This driver expects all application buffers attached to BDs to be in cache coherent memory. If cache is used in the system, buffers for transmit MUST be flushed from the cache before passing the associated BD to this driver. Buffers for receive MUST be invalidated before accessing the data.</p>
-<p><b> Alignment </b></p>
-<p>For BDs:</p>
-<p>Minimum alignment is defined by the constant XAXIDMA_BD_MINIMUM_ALIGNMENT. This is the smallest alignment allowed by both hardware and software for them to properly work.</p>
-<p>If the descriptor ring is to be placed in cached memory, alignment also MUST be at least the processor's cache-line size. Otherwise, system instability occurs. For alignment larger than the cache line size, multiple cache line size alignment is required.</p>
-<p>Aside from the initial creation of the descriptor ring (see <a class="el" href="group__axidma__v9__0.html#ga5c6d6f492642dd355478c3a853556d6b" title="Using a memory segment allocated by the caller, This fundtion creates and setup the BD ring...">XAxiDma_BdRingCreate()</a>), there are no other run-time checks for proper alignment of BDs.</p>
-<p>For application data buffers:</p>
-<p>Application data buffers may reside on any alignment if DRE is built into the hardware. Otherwise, application data buffer must be word-aligned. The word is defined by XPAR_AXIDMA_0_M_AXIS_MM2S_TDATA_WIDTH for transmit and XPAR_AXIDMA_0_S_AXIS_S2MM_TDATA_WIDTH for receive.</p>
-<p>For scatter gather transfers that have more than one BDs in the chain of BDs, Each BD transfer length must be multiple of word too. Otherwise, internal error happens in the hardware.</p>
-<p><b> Error Handling </b></p>
-<p>The DMA engine will halt on all error conditions. It requires the software to do a reset before it can start process new transfer requests.</p>
-<p><b> Restart After Stopping </b></p>
-<p>After the DMA engine has been stopped (through reset or reset after an error) the software keeps track of the current BD pointer when reset happens, and processing of BDs can be resumed through <a class="el" href="group__axidma__v9__0.html#gaafd18a1df185c30b4745c147e3295ac3" title="Start a DMA channel, updates current descriptors and Allow DMA transactions to commence on a given ch...">XAxiDma_BdRingStart()</a>.</p>
-<p><b> Limitations </b></p>
-<p>This driver does not have any mechanisms for mutual exclusion. It is up to the application to provide this protection.</p>
-<p><b> Hardware Defaults &amp; Exclusive Use </b></p>
-<p>After the initialization or reset, the DMA engine is in the following default mode:</p><ul>
-<li>All interrupts are disabled.</li>
-<li>Interrupt coalescing counter is 1.</li>
-<li>The DMA engine is not running (halted). Each DMA channel is started separately, using <a class="el" href="group__axidma__v9__0.html#ga7b38bc9220c391823219937580bd816f" title="Start a DMA channel and Allow DMA transactions to commence on a given channel if descriptors are read...">XAxiDma_StartBdRingHw()</a> if no BDs are setup for transfer yet, or <a class="el" href="group__axidma__v9__0.html#gaafd18a1df185c30b4745c147e3295ac3" title="Start a DMA channel, updates current descriptors and Allow DMA transactions to commence on a given ch...">XAxiDma_BdRingStart()</a> otherwise.</li>
-</ul>
-<p>The driver has exclusive use of the registers and BDs. All accesses to the registers and BDs should go through the driver interface.</p>
-<p><b> Debug Print </b></p>
-<p>To see the debug print for the driver, please put "-DDEBUG" as the extra compiler flags in software platform settings. Also comment out the line in xdebug.h: "#undef DEBUG".</p>
-<p><b>Changes From v1.00a</b></p>

- *
- * @file xaxidma_example_sg_intr.c
- *
- * This file demonstrates how to use the xaxidma driver on the Xilinx AXI
- * DMA core (AXIDMA) to transfer packets in interrupt mode when the AXIDMA
- * core is configured in Scatter Gather Mode
- *
- * We show how to do multiple packets transfers, as well as how to do multiple
- * BDs per packet transfers.
- *
- * This code assumes a loopback hardware widget is connected to the AXI DMA
- * core for data packet loopback.
- *
- * To see the debug print, you need a Uart16550 or uartlite in your system,
- * and please set "-DDEBUG" in your compiler options. You need to rebuild your
- * software executable.
- *
- * Make sure that MEMORY_BASE is defined properly as per the HW system. The
- * h/w system built in Area mode has a maximum DDR memory limit of 64MB. In
- * throughput mode, it is 512MB.  These limits are need to ensured for
- * proper operation of this code.

-/**
- *
- * @file xaxidma_example_sg_poll.c
- *
- * This file demonstrates how to use the xaxidma driver on the Xilinx AXI
- * DMA core (AXIDMA) to transfer packets in polling mode when the AXIDMA
- * core is configured in Scatter Gather Mode.
- *
- * This code assumes a loopback hardware widget is connected to the AXI DMA
- * core for data packet loopback.
- *
- * To see the debug print, you need a Uart16550 or uartlite in your system,
- * and please set "-DDEBUG" in your compiler options. You need to rebuild your
- * software executable.
- *
- * Make sure that MEMORY_BASE is defined properly as per the HW system. The
- * h/w system built in Area mode has a maximum DDR memory limit of 64MB. In
- * throughput mode, it is 512MB.  These limits are need to ensured for
- * proper operation of this code.
- *
- *
- * <pre>

- * @file xaxidma_example_simple_intr.c
- *
- * This file demonstrates how to use the xaxidma driver on the Xilinx AXI
- * DMA core (AXIDMA) to transfer packets.in interrupt mode when the AXIDMA core
- * is configured in simple mode
- *
- * This code assumes a loopback hardware widget is connected to the AXI DMA
- * core for data packet loopback.
- *
- * To see the debug print, you need a Uart16550 or uartlite in your system,
- * and please set "-DDEBUG" in your compiler options. You need to rebuild your
- * software executable.
- *
- * Make sure that MEMORY_BASE is defined properly as per the HW system. The
- * h/w system built in Area mode has a maximum DDR memory limit of 64MB. In
- * throughput mode, it is 512MB.  These limits are need to ensured for
- * proper operation of this code.
- *
- *
- * <pre>
- * MODIFICATION HISTORY:
- *
- * Ver   Who  Date     Changes
- * ----- ---- -------- -------------------------------------------------------

- *
- * This file demonstrates how to use the xaxidma driver on the Xilinx AXI
- * DMA core (AXIDMA) to transfer packets in polling mode when the AXI DMA core
- * is configured in simple mode.
- *
- * This code assumes a loopback hardware widget is connected to the AXI DMA
- * core for data packet loopback.
- *
- * To see the debug print, you need a Uart16550 or uartlite in your system,
- * and please set "-DDEBUG" in your compiler options. You need to rebuild your
- * software executable.
- *
- * Make sure that MEMORY_BASE is defined properly as per the HW system. The
- * h/w system built in Area mode has a maximum DDR memory limit of 64MB. In
- * throughput mode, it is 512MB.  These limits are need to ensured for
- * proper operation of this code.
- *
- *

- *
- * Ver   Who  Date     Changes
- * ----- ---- -------- -------------------------------------------------------
- * 4.00a rkv  02/22/11 New example created for simple DMA, this example is for
- *       	       simple DMA
- * 5.00a srt  03/06/12 Added Flushing and Invalidation of Caches to fix CRs
- *		       648103, 648701.
- *		       Added V7 DDR Base Address to fix CR 649405.
- * 6.00a srt  03/27/12 Changed API calls to support MCDMA driver.
- * 7.00a srt  06/18/12 API calls are reverted back for backward compatibility.
- * 7.01a srt  11/02/12 Buffer sizes (Tx and Rx) are modified to meet maximum
- *		       DDR memory limit of the h/w system built with Area mode
- * 7.02a srt  03/01/13 Updated DDR base address for IPI designs (CR 703656).

-/**
- *
- * @file xaximcdma_example_sg_intr.c
- *
- * This file demonstrates how to use the xaxidma driver on the Xilinx AXI
- * DMA core v6_00_a (AXIDMA) to transfer packets in interrupt mode for
- * Multiple Channel capability.
- * Thi example is designed to work only when AXIDMA core is configured
- * in Scatter Gather Mode and Multiple Channel mode.
- *
- * We show how to do multiple packets transfers, as well as how to do multiple
- * BDs per packet transfers.
- *
- * This code is tested only with two channels on both Tx and Rx.
- * This code assumes a loopback hardware widget is connected to the AXI DMA
- * core for data packet loopback. The loopback widget is configured in a way
- * that, when a packet is transmitted on "Tx Channel 0" it will be received
- * on the "Rx channel 1" and if "Tx Channel 1" it is on Rx Channel 0.
- * Both the cases are included in this example.
- *
- * To see the debug print, you need a Uart16550 or uartlite in your system,
- * and please set "-DDEBUG" in your compiler options. You need to rebuild your
- * software executable.
- *
- * Make sure that MEMORY_BASE is defined properly as per the HW system. The
- * h/w system built in Area mode has a maximum DDR memory limit of 64MB. In
- * throughput mode, it is 512MB.  These limits are need to ensured for
- * proper operation of this code.
- *
- * <pre>
- * MODIFICATION HISTORY:
- *
- * Ver   Who  Date     Changes
- * ----- ---- -------- -------------------------------------------------------
- * 1.00a srt  03/27/12 First release
- * 2.00a srt  06/18/12 API calls are reverted back for backward compatibility.
- * 2.01a srt  11/02/12 Buffer sizes (Tx and Rx) are modified to meet maximum
- *		       DDR memory limit of the h/w system built with Area mode
- * 7.02a srt  03/01/13 Updated DDR base address for IPI designs (CR 703656).

-/**
- *
- * @file xaxidma_poll_multi_pkts.c
- *
- * This file demonstrates how to use the xaxidma driver on the Xilinx AXI
- * DMA core (AXIDMA) to transfer multiple packets in polling mode when the
- * AXI DMA core is configured in Scatter Gather Mode.
- *
- * This code assumes a loopback hardware widget is connected to the AXI DMA
- * core for data packet loopback.
- *
- * To see the debug print, you need a Uart16550 or uartlite in your system,
- * and please set "-DDEBUG" in your compiler options. You need to rebuild your
- * software executable.
- *
- * Make sure that MEMORY_BASE is defined properly as per the HW system. The
- * h/w system built in Area mode has a maximum DDR memory limit of 64MB. In
- * throughput mode, it is 512MB.  These limits are need to ensured for
- * proper operation of this code.
- *
- *
- * <pre>

-/**
-*
-* @file xaxidma.h
-* @addtogroup axidma_v9_0
-* @{
-* @details
-*
-* This is the driver API for the AXI DMA engine.
-*
-* For a full description of DMA features, please see the hardware spec. This
-* driver supports the following features:
-*
-*   - Scatter-Gather DMA (SGDMA)
-*   - Simple DMA
-*   - Interrupts
-*   - Programmable interrupt coalescing for SGDMA
-*   - APIs to manage Buffer Descriptors (BD) movement to and from the SGDMA
-*     engine
-*
-* <b>Simple DMA</b>
-*
-* Simple DMA allows the application to define a single transaction between DMA
-* and Device. It has two channels: one from the DMA to Device and the other
-* from Device to DMA. Application has to set the buffer address and
-* length fields to initiate the transfer in respective channel.
-*
-* <b>Transactions</b>
-*
-* The object used to describe a transaction is referred to as a Buffer
-* Descriptor (BD). Buffer descriptors are allocated in the user application.
-* The user application needs to set buffer address, transfer length, and
-* control information for this transfer. The control information includes
-* SOF and EOF. Definition of those masks are in xaxidma_hw.h
-*
-* <b>Scatter-Gather DMA</b>
-*
-* SGDMA allows the application to define a list of transactions in memory which
-* the hardware will process without further application intervention. During
-* this time, the application is free to continue adding more work to keep the
-* Hardware busy.
-*
-* User can check for the completion of transactions through polling the
-* hardware, or interrupts.
-*
-* SGDMA processes whole packets. A packet is defined as a series of
-* data bytes that represent a message. SGDMA allows a packet of data to be
-* broken up into one or more transactions. For example, take an Ethernet IP
-* packet which consists of a 14 byte header followed by a 1 or more bytes of
-* payload. With SGDMA, the application may point a BD to the header and another
-* BD to the payload, then transfer them as a single message. This strategy can
-* make a TCP/IP stack more efficient by allowing it to keep packet header and
-* data in different memory regions instead of assembling packets into
-* contiguous blocks of memory.
-*
-* <b>BD Ring Management</b>
-*
-* BD rings are shared by the software and the hardware.
-*
-* The hardware expects BDs to be setup as a linked list. The DMA hardware walks
-* through the list by following the next pointer field of a completed BD.
-* The hardware stops processing when the just completed BD is the same as the
-* BD specified in the Tail Ptr register in the hardware.
-*
-* The last BD in the ring is linked to the first BD in the ring.
-*
-* All BD management are done inside the driver. The user application should not
-* directly modify the BD fields. Modifications to the BD fields should always
-* go through the specific API functions.
-*
-* Within the ring, the driver maintains four groups of BDs. Each group consists
-* of 0 or more adjacent BDs:
-*
-*   - Free: The BDs that can be allocated by the application with
-*     XAxiDma_BdRingAlloc().
-*
-*   - Pre-process: The BDs that have been allocated with
-*     XAxiDma_BdRingAlloc(). These BDs are under application control. The
-*     application modifies these BDs through driver API to prepare them
-*     for DMA transactions.
-*
-*   - Hardware: The BDs that have been enqueued to hardware with
-*     XAxiDma_BdRingToHw(). These BDs are under hardware control and may be in a
-*     state of awaiting hardware processing, in process, or processed by
-*     hardware. It is considered an error for the application to change BDs
-*     while they are in this group. Doing so can cause data corruption and lead
-*     to system instability.
-*
-*   - Post-process: The BDs that have been processed by hardware and have
-*     been extracted from the Hardware group with XAxiDma_BdRingFromHw().
-*     These BDs are under application control. The application can check the
-*     transfer status of these BDs. The application use XAxiDma_BdRingFree()
-*     to put them into the Free group.
-*
-* BDs are expected to transition in the following way for continuous
-* DMA transfers:
-* <pre>
-*
-*         XAxiDma_BdRingAlloc()                   XAxiDma_BdRingToHw()
-*   Free ------------------------> Pre-process ----------------------> Hardware
-*                                                                      |
-*    /|\                                                               |
-*     |   XAxiDma_BdRingFree()                  XAxiDma_BdRingFromHw() |
-*     +--------------------------- Post-process <----------------------+
-*
-* </pre>
-*
-* When a DMA transfer is to be cancelled before enqueuing to hardware,
-* application can return the requested BDs to the Free group using
-* XAxiDma_BdRingUnAlloc(), as shown below:
-* <pre>
-*
-*         XAxiDma_BdRingUnAlloc()
-*   Free <----------------------- Pre-process
-*
-* </pre>
-*
-* The API provides functions for BD list traversal:
-* - XAxiDma_BdRingNext()
-* - XAxiDma_BdRingPrev()
-*
-* These functions should be used with care as they do not understand where
-* one group ends and another begins.
-*
-* <b>SGDMA Descriptor Ring Creation</b>
-*
-* BD ring is created using XAxiDma_BdRingCreate(). The memory for the BD ring
-* is allocated by the application, and it has to be contiguous. Physical
-* address is required to setup the BD ring.
-*
-* The applicaiton can use XAxiDma_BdRingMemCalc() to find out the amount of
-* memory needed for a certain number of BDs. XAxiDma_BdRingCntCalc() can be
-* used to find out how many BDs can be allocated for certain amount of memory.
-*
-* A helper function, XAxiDma_BdRingClone(), can speed up the BD ring setup if
-* the BDs have same types of controls, for example, SOF and EOF. After
-* using the XAxiDma_BdRingClone(), the application only needs to setup the
-* buffer address and transfer length. Note that certain BDs in one packet,
-* for example, the first BD and the last BD, may need to setup special
-* control information.
-*
-* <b>Descriptor Ring State Machine</b>
-*
-* There are two states of the BD ring:
-*
-*   - HALTED (H), where hardware is not running
-*
-*   - NOT HALTED (NH), where hardware is running
-*
-* The following diagram shows the state transition for the DMA engine:
-*
-* <pre>
-*   _____ XAxiDma_StartBdRingHw(), or XAxiDma_BdRingStart(),   ______
-*   |   |               or XAxiDma_Resume()                    |    |
-*   | H |----------------------------------------------------->| NH |
-*   |   |<-----------------------------------------------------|    |
-*   -----   XAxiDma_Pause() or XAxiDma_Reset()                 ------
-* </pre>
-*
-* <b>Interrupt Coalescing</b>
-*
-* SGDMA provides control over the frequency of interrupts through interrupt
-* coalescing. The DMA engine provides two ways to tune the interrupt
-* coalescing:
-*
-* - The packet threshold counter. Interrupt will fire once the
-*   programmable number of packets have been processed by the engine.
-*
-* - The packet delay timer counter. Interrupt will fire once the
-*   programmable amount of time has passed after processing the last packet,
-*   and no new packets to process. Note that the interrupt will only fire if
-*   at least one packet has been processed.
-*
-* <b> Interrupt </b>
-*
-* Interrupts are handled by the user application. Each DMA channel has its own
-* interrupt ID. The driver provides APIs to enable/disable interrupt,
-* and tune the interrupt frequency regarding to packet processing frequency.
-*
-* <b> Software Initialization </b>
-*
-*
-* To use the Simple mode DMA engine for transfers, the following setup is
-* required:
-*
-* - DMA Initialization using XAxiDma_CfgInitialize() function. This step
-*   initializes a driver instance for the given DMA engine and resets the
-*   engine.
-*
-* - Enable interrupts if chosen to use interrupt mode. The application is
-*   responsible for setting up the interrupt system, which includes providing
-*   and connecting interrupt handlers and call back functions, before
-*   enabling the interrupts.
-*
-* - Set the buffer address and length field in respective channels to start
-*   the DMA transfer
-*
-* To use the SG mode DMA engine for transfers, the following setup are
-* required:
-*
-* - DMA Initialization using XAxiDma_CfgInitialize() function. This step
-*   initializes a driver instance for the given DMA engine and resets the
-*   engine.
-*
-* - BD Ring creation. A BD ring is needed per DMA channel and can be built by
-*   calling XAxiDma_BdRingCreate().
-*
-* - Enable interrupts if chose to use interrupt mode. The application is
-*   responsible for setting up the interrupt system, which includes providing
-*   and connecting interrupt handlers and call back functions, before
-*   enabling the interrupts.
-*
-* - Start a DMA transfer: Call XAxiDma_BdRingStart() to start a transfer for
-*   the first time or after a reset, and XAxiDma_BdRingToHw() if the channel
-*   is already started. Calling XAxiDma_BdRingToHw() when a DMA channel is not
-*   running will not put the BDs to the hardware, and the BDs will be processed
-*   later when the DMA channel is started through XAxiDma_BdRingStart().
-*
-* <b> How to start DMA transactions </b>
-*
-* The user application uses XAxiDma_BdRingToHw() to submit BDs to the hardware
-* to start DMA transfers.
-*
-* For both channels, if the DMA engine is currently stopped (using
-* XAxiDma_Pause()), the newly added BDs will be accepted but not processed
-* until the DMA engine is started, using XAxiDma_BdRingStart(), or resumed,
-* using XAxiDma_Resume().
-*
-* <b> Software Post-Processing on completed DMA transactions </b>
-*
-* If the interrupt system has been set up and the interrupts are enabled,
-* a DMA channels notifies the software about the completion of a transfer
-* through interrupts. Otherwise, the user application can poll for
-* completions of the BDs, using XAxiDma_BdRingFromHw() or
-* XAxiDma_BdHwCompleted().
-*
-* - Once BDs are finished by a channel, the application first needs to fetch
-*   them from the channel using XAxiDma_BdRingFromHw().
-*
-* - On the TX side, the application now could free the data buffers attached to
-*   those BDs as the data in the buffers has been transmitted.
-*
-* - On the RX side, the application now could use the received data in the
-*	buffers attached to those BDs.
-*
-* - For both channels, completed BDs need to be put back to the Free group
-*   using XAxiDma_BdRingFree(), so they can be used for future transactions.
-*
-* - On the RX side, it is the application's responsibility to have BDs ready
-*   to receive data at any time. Otherwise, the RX channel refuses to
-*   accept any data if it has no RX BDs.
-*
-* <b> Examples </b>
-*
-* We provide five examples to show how to use the driver API:
-* - One for SG interrupt mode (xaxidma_example_sg_intr.c), multiple BD/packets transfer
-* - One for SG polling mode (xaxidma_example_sg_poll.c), single BD transfer.
-* - One for SG polling mode (xaxidma_poll_multi_pkts.c), multiple BD/packets transfer
-* - One for simple polling mode (xaxidma_example_simple_poll.c)
-* - One for simple Interrupt mode (xaxidma_example_simple_intr.c)
-*
-* <b> Address Translation </b>
-*
-* All buffer addresses and BD addresses for the hardware are physical
-* addresses. The user application is responsible to provide physical buffer
-* address for the BD upon BD ring creation. The user application accesses BD
-* through its virtual addess. The driver maintains the address translation
-* between the physical and virtual address for BDs.
-*
-* <b> Cache Coherency </b>
-*
-* This driver expects all application buffers attached to BDs to be in cache
-* coherent memory. If cache is used in the system, buffers for transmit MUST
-* be flushed from the cache before passing the associated BD to this driver.
-* Buffers for receive MUST be invalidated before accessing the data.
-*
-* <b> Alignment </b>
-*
-* For BDs:
-*
-* Minimum alignment is defined by the constant XAXIDMA_BD_MINIMUM_ALIGNMENT.
-* This is the smallest alignment allowed by both hardware and software for them
-* to properly work.
-*
-* If the descriptor ring is to be placed in cached memory, alignment also MUST
-* be at least the processor's cache-line size. Otherwise, system instability
-* occurs. For alignment larger than the cache line size, multiple cache line
-* size alignment is required.
-*
-* Aside from the initial creation of the descriptor ring (see
-* XAxiDma_BdRingCreate()), there are no other run-time checks for proper
-* alignment of BDs.
-*
-* For application data buffers:
-*
-* Application data buffers may reside on any alignment if DRE is built into the
-* hardware. Otherwise, application data buffer must be word-aligned. The word
-* is defined by XPAR_AXIDMA_0_M_AXIS_MM2S_TDATA_WIDTH for transmit and
-* XPAR_AXIDMA_0_S_AXIS_S2MM_TDATA_WIDTH for receive.
-*
-* For scatter gather transfers that have more than one BDs in the chain of BDs,
-* Each BD transfer length must be multiple of word too. Otherwise, internal
-* error happens in the hardware.
-*
-* <b> Error Handling </b>
-*
-* The DMA engine will halt on all error conditions. It requires the software
-* to do a reset before it can start process new transfer requests.
-*
-* <b> Restart After Stopping </b>
-*
-* After the DMA engine has been stopped (through reset or reset after an error)
-* the software keeps track of the current BD pointer when reset happens, and
-* processing of BDs can be resumed through XAxiDma_BdRingStart().
-*
-* <b> Limitations </b>
-*
-* This driver does not have any mechanisms for mutual exclusion. It is up to
-* the application to provide this protection.
-*
-* <b> Hardware Defaults & Exclusive Use </b>
-*
-* After the initialization or reset, the DMA engine is in the following
-* default mode:
-* - All interrupts are disabled.
-*
-* - Interrupt coalescing counter is 1.
-*
-* - The DMA engine is not running (halted). Each DMA channel is started
-*   separately, using XAxiDma_StartBdRingHw() if no BDs are setup for transfer
-*   yet, or XAxiDma_BdRingStart() otherwise.
-*
-* The driver has exclusive use of the registers and BDs. All accesses to the
-* registers and BDs should go through the driver interface.
-*
-* <b> Debug Print </b>
-*
-* To see the debug print for the driver, please put "-DDEBUG" as the extra
-* compiler flags in software platform settings. Also comment out the line in
-* xdebug.h: "#undef DEBUG".
-*
-* <b>Changes From v1.00a</b>
-*
-* . We have changes return type for XAxiDma_BdSetBufAddr() from void to int
-* . We added XAxiDma_LookupConfig() so that user does not need to look for the
-* hardware settings anymore.

- *
- * Buffer descriptor (BD) management API.
- *
- * <b> Buffer Descriptors </b>
- *
- * A BD defines a DMA transaction (see "Transaction" section in xaxidma.h).
- * All accesses to a BD go through this set of API.
- *
- * The XAxiDma_Bd structure defines a BD. The first XAXIDMA_BD_HW_NUM_BYTES
- * are shared between hardware and software.
- *
- * <b> Actual Transfer Length </b>
- *
- * The actual transfer length for receive could be smaller than the requested
- * transfer length. The hardware sets the actual transfer length in the
- * completed BD. The API to retrieve the actual transfer length is
- * XAxiDma_GetActualLength().
- *
- * <b> User IP words </b>
- *
- * There are 5 user IP words in each BD.
- *
- * If hardware does not have the StsCntrl stream built in, then these words
- * are not usable. Retrieving these words get a NULL pointer and setting
- * these words results an error.
- *
- * <b> Performance </b>
- *
- * BDs are typically in a non-cached memory space. Reducing the number of
- * I/O operations to BDs can improve overall performance of the DMA channel.
- *
- * <pre>

-* This is a guide on how to move from using the xlldma driver to use xaxidma
-* driver.

-* MODIFICATION HISTORY:
-*
-* Ver   Who  Date     Changes
-* ----- ---- -------- -------------------------------------------------------
-* 1.00a jz   05/18/10 First release
-* 2.00a jz   08/10/10 Second release, added in xaxidma_g.c, xaxidma_sinit.c,
-*                     updated tcl file, added xaxidma_porting_guide.h
-* 4.00a rkv  02/22/11 Added support for simple DMA mode
-* 6.00a srt  03/27/12 Added support for MCDMA mode
-* 7.00a srt  06/18/12 API calls are reverted back for backward compatibility.
-*
-* </pre>
-*
-* <b>Overview</b>
-*
-* The API for xaxidma driver is similar to xlldma driver. The prefix for the
-* API functions and structures is XAxiDma_ for the xaxidma driver.
-*
-* Due to hardware feature changes, signatures of some API functions are a
-* little bit different from the xlldma API functions.
-*
-* We present API functions:
-* - That only have prefix changes
-* - That have different return type
-* - That are new API functions
-* - That have been removed
-*
-* Note that data structures have different prefix of XAxiDma_. Those API
-* functions, that have data structures with prefix change, are considered as
-* prefix change.
-*
-* <b>API Functions That Only Have Prefix Changes</b>

-*
-* <b>API Functions That Are New API Functions</b>
-*
-* Now that the AXI DMA core is a standalone core, some new API are intrduced.
-* Some other functions are added due to hardware interface change, so to
-* replace old API functions.
-*
-* - XAxiDma_Config *XAxiDma_LookupConfig(u32 DeviceId);

-*
-* <b>API Functions That Have Been Removed</b>
-*
-* Please see individual function comments for how to replace the removed API
-* function with new API functions.
-*

-<div class="textblock"><p>This is the main header file for Xilinx AXI4-Stream Switch Control Router core. It is used for routing streams where masters in the system do not know final destination address.</p>
-<p><b>Core Features </b></p>
-<p>For a full description of AXI4-Stream Switch Control Router, please see the hardware specification.</p>
-<p><b>Software Initialization &amp; Configuration</b></p>
-<p>The application needs to do following steps in order for preparing the AXI4-Stream Switch Control Router core to be ready.</p>
-<ul>
-<li>Call XAxisScr_LookupConfig using a device ID to find the core configuration.</li>
-<li>Call XAxisScr_CfgInitialize to initialize the device and the driver instance associated with it.</li>
-</ul>
-<p><b>Interrupts </b></p>
-<p>This driver does not have interrupt mechanism.</p>
-<p><b> Virtual Memory </b></p>
-<p>This driver supports Virtual Memory. The RTOS is responsible for calculating the correct device base address in Virtual Memory space.</p>
-<p><b> Threads </b></p>
-<p>This driver is not thread safe. Any needs for threads or thread mutual exclusion must be satisfied by the layer above this driver.</p>
-<p><b> Asserts </b></p>
-<p>Asserts are used within all Xilinx drivers to enforce constraints on argument values. Asserts can be turned off on a system-wide basis by defining at compile time, the NDEBUG identifier. By default, asserts are turned on and it is recommended that users leave asserts on during development.</p>
-<p><b> Building the driver </b></p>
-<p>The XAXI4-Stream Switch driver is composed of several source files. This allows the user to build and link only those parts of the driver that are necessary.</p>

-* This is the main header file for Xilinx AXI4-Stream Switch Control Router
-* core. It is used for routing streams where masters in the system do not know
-* final destination address.
-*
-* <b>Core Features </b>
-*
-* For a full description of AXI4-Stream Switch Control Router, please see the
-* hardware specification.
-*
-* <b>Software Initialization & Configuration</b>
-*
-* The application needs to do following steps in order for preparing the
-* AXI4-Stream Switch Control Router core to be ready.
-*
-* - Call XAxisScr_LookupConfig using a device ID to find the core
-*   configuration.
-* - Call XAxisScr_CfgInitialize to initialize the device and the driver
-*   instance associated with it.
-*
-* <b>Interrupts </b>
-*
-* This driver does not have interrupt mechanism.
-*
-* <b> Virtual Memory </b>
-*
-* This driver supports Virtual Memory. The RTOS is responsible for calculating
-* the correct device base address in Virtual Memory space.
-*
-* <b> Threads </b>
-*
-* This driver is not thread safe. Any needs for threads or thread mutual
-* exclusion must be satisfied by the layer above this driver.
-*
-* <b> Asserts </b>
-*
-* Asserts are used within all Xilinx drivers to enforce constraints on argument
-* values. Asserts can be turned off on a system-wide basis by defining at
-* compile time, the NDEBUG identifier. By default, asserts are turned on and it
-* is recommended that users leave asserts on during development.
-*
-* <b> Building the driver </b>
-*
-* The XAXI4-Stream Switch driver is composed of several source files. This
-* allows the user to build and link only those parts of the driver that are
-* necessary.

-<p>Used for spaces where the address range of the region is smaller than the data width. If the memory range is greater than 2 ** width, the patterns used in XUT_WALKONES and XUT_WALKZEROS will repeat on a boundry of a power of two making it more difficult to detect addressing errors. The XUT_INCREMENT and XUT_INVERSEADDR tests suffer the same problem. Ideally, if large blocks of memory are to be tested, break them up into smaller regions of memory to allow the test patterns used not to repeat over the region tested. </p>

-* @file xutil.h

-* @{
-*
-* This file contains utility functions such as memory test functions.
-*
-* <b>Memory test description</b>
-*
-* A subset of the memory tests can be selected or all of the tests can be run
-* in order. If there is an error detected by a subtest, the test stops and the
-* failure code is returned. Further tests are not run even if all of the tests
-* are selected.
-*
-* Subtest descriptions:
-* <pre>
-* XUT_ALLMEMTESTS:
-*       Runs all of the following tests
-*
-* XUT_INCREMENT:
-*       Incrementing Value Test.
-*       This test starts at 'XUT_MEMTEST_INIT_VALUE' and uses the incrementing
-*       value as the test value for memory.
-*
-* XUT_WALKONES:
-*       Walking Ones Test.
-*       This test uses a walking '1' as the test value for memory.
-*       location 1 = 0x00000001
-*       location 2 = 0x00000002
-*       ...
-*
-* XUT_WALKZEROS:
-*       Walking Zero's Test.
-*       This test uses the inverse value of the walking ones test
-*       as the test value for memory.
-*       location 1 = 0xFFFFFFFE
-*       location 2 = 0xFFFFFFFD
-*       ...
-*
-* XUT_INVERSEADDR:
-*       Inverse Address Test.
-*       This test uses the inverse of the address of the location under test
-*       as the test value for memory.
-*
-* XUT_FIXEDPATTERN:
-*       Fixed Pattern Test.
-*       This test uses the provided patters as the test value for memory.
-*       If zero is provided as the pattern the test uses '0xDEADBEEF".
-* </pre>
-*
-* <i>WARNING</i>
-*
-* The tests are <b>DESTRUCTIVE</b>. Run before any initialized memory spaces
-* have been set up.
-*
-* The address, Addr, provided to the memory tests is not checked for
-* validity except for the NULL case. It is possible to provide a code-space
-* pointer for this test to start with and ultimately destroy executable code
-* causing random failures.
-*
-* @note
-*
-* Used for spaces where the address range of the region is smaller than
-* the data width. If the memory range is greater than 2 ** width,
-* the patterns used in XUT_WALKONES and XUT_WALKZEROS will repeat on a
-* boundry of a power of two making it more difficult to detect addressing
-* errors. The XUT_INCREMENT and XUT_INVERSEADDR tests suffer the same
-* problem. Ideally, if large blocks of memory are to be tested, break
-* them up into smaller regions of memory to allow the test patterns used
-* not to repeat over the region tested.
-*
-* <pre>
-* MODIFICATION HISTORY:
-*
-* Ver    Who    Date    Changes
-* ----- ---- -------- -----------------------------------------------
-* 1.00a ecm  11/01/01 First release
-* 1.00a xd   11/03/04 Improved support for doxygen.

-## @BEGIN_CHANGELOG
-##
-##     09/17/07 ecm  Removed the PCI specific connections
-##              Moved to the Linux MLD.
-##     10/24/07 rpm  Fixed KIND_OF_INTR bug in canonicals and
-##              also generalized match on external interrupts
-##     06/25/09 sdm  Updated so that canonical definitions are
-##              not generated when instance name matches
-##              canonical name
-##     04/27/10 sdm Updated the tcl so that the defintions are generated in
-##		the xparameters.h to know whether the optional registers
-##		SIE, CIE and IVR are enabled in the HW - Refer CR 555392
-##     05/24/11 hvm updated tcl to generate vector ids for external interrupts
-##		CR565336
-##     06/15/11 hvm Updated tcl with bypassing the external interrupt definition
-##		in xredefine_intc function. CR613925.
-##     01/19/12 Updated the intc_define_use_dcr function so that it doesnot
-##              error out if there is more than one bus interface to the
-##              intc controller. The new common::version of the AXI_INTC can have two
-##              bus interfaces to support the fast interrupt for MicroBlaze.
-##              Updated for the generation of the C_HAS_FAST xparameters
-##     08/16/12 bss added generation of C_IVAR_RESET_VALUE xparameters
-##
-##     01/29/13 bss Added check_cascade and get_intctype to support
-##		    Cascade mode. Modified intc_define_vector_table procedure
-##		    to generate interrupt IDs as 32..63 and 64..95 and so on
-##		    for Slave controllers in Cascade mode
-##     01/22/14 bss Modified check_cascade to fix CR#764865
-##     17/02/14 adk Fixed the CR:771287 in intc_define_vector_table
-##		    if number of interrupt ports not equal to total numer of
-##		    interrupts returning immediatly.And in the xredefine_intc
-##		    if there is not interrupt source returining immediately.
-##     4/8/14   bss Modified xredefine_intc to handle external interrupt pins
-##		    correctly (CR#799609).
-##     11/3/14 adk  added generation of C_HAS_ILR parameter to xparameters.h
-##		    (CR#828046).

-<div class="textblock"><p>The Xilinx interrupt controller driver component. This component supports the Xilinx interrupt controller.</p>
-<p>The interrupt controller driver uses the idea of priority for the various handlers. Priority is an integer within the range of 0 and 31 inclusive with 0 being the highest priority interrupt source.</p>
-<p>The Xilinx interrupt controller supports the following features:</p>
-<ul>
-<li>specific individual interrupt enabling/disabling</li>
-<li>specific individual interrupt acknowledging</li>
-<li>attaching specific callback function to handle interrupt source</li>
-<li>master enable/disable</li>
-<li>single callback per interrupt or all pending interrupts handled for each interrupt of the processor</li>
-</ul>
-<p>The acknowledgement of the interrupt within the interrupt controller is selectable, either prior to the device's handler being called or after the handler is called. This is necessary to support interrupt signal inputs which are either edge or level signals. Edge driven interrupt signals require that the interrupt is acknowledged prior to the interrupt being serviced in order to prevent the loss of interrupts which are occurring extremely close together. A level driven interrupt input signal requires the interrupt to acknowledged after servicing the interrupt to ensure that the interrupt only generates a single interrupt condition.</p>
-<p>Details about connecting the interrupt handler of the driver are contained in the source file specific to interrupt processing, <a class="el" href="xintc__intr_8c.html">xintc_intr.c</a>.</p>
-<p>This driver is intended to be RTOS and processor independent. It works with physical addresses only. Any needs for dynamic memory management, threads or thread mutual exclusion, virtual memory, or cache control must be satisfied by the layer above this driver.</p>
-<p><b>Interrupt Vector Tables</b></p>
-<p>The interrupt vector table for each interrupt controller device is declared statically in <a class="el" href="xintc__g_8c.html">xintc_g.c</a> within the configuration data for each instance. The device ID of the interrupt controller device is used by the driver as a direct index into the configuration data table - to retrieve the vector table for an instance of the interrupt controller. The user should populate the vector table with handlers and callbacks at run-time using the <a class="el" href="group__intc__v3__4.html#gaee9ec5873a764994d64b4da35a110084" title="Makes the connection between the Id of the interrupt source and the associated handler that is to run...">XIntc_Connect()</a> and <a class="el" href="group__intc__v3__4.html#ga8f7caaeb26b6b264fffefbd32f90f855" title="Updates the interrupt table with the Null Handler and NULL arguments at the location pointed at by th...">XIntc_Disconnect()</a> functions.</p>
-<p>Each vector table entry corresponds to a device that can generate an interrupt. Each entry contains an interrupt handler function and an argument to be passed to the handler when an interrupt occurs. The tools default this argument to the base address of the interrupting device. Note that the device driver interrupt handlers given in this file do not take a base address as an argument, but instead take a pointer to the driver instance. This means that although the table is created statically, the user must still use <a class="el" href="group__intc__v3__4.html#gaee9ec5873a764994d64b4da35a110084" title="Makes the connection between the Id of the interrupt source and the associated handler that is to run...">XIntc_Connect()</a> when the interrupt handler takes an argument other than the base address. This is only to say that the existence of the static vector tables should not mislead the user into thinking they no longer need to register/connect interrupt handlers with this driver.</p>

-* This file contains a design example using the Interrupt Controller driver
-* (XIntc) and hardware device. Please reference other device driver examples to
-* see more examples of how the intc and interrupts can be used by a software
-* application.
-*
-* This example shows the use of the Interrupt Controller both with a PowerPC
-* and MicroBlaze processor.
-*
-* @note
-*		This example can also be used for Cascade mode interrupt
-*		controllers by using the interrupt IDs generated in
-*		xparameters.h. For Cascade mode, Interrupt IDs are generated
-*		in xparameters.h as shown below:
-*
-*	    Master/Primary INTC
-*		 ______
-*		|      |-0      Secondary INTC
-*		|      |-.         ______

-*		All driver functions has to be called using
-*		DeviceId/InstancePtr of Primary/Master Controller only. Driver

-* @details
-*
-* The Xilinx interrupt controller driver component. This component supports the
-* Xilinx interrupt controller.
-*
-* The interrupt controller driver uses the idea of priority for the various
-* handlers. Priority is an integer within the range of 0 and 31 inclusive with
-* 0 being the highest priority interrupt source.
-*
-* The Xilinx interrupt controller supports the following features:
-*
-*   - specific individual interrupt enabling/disabling
-*   - specific individual interrupt acknowledging
-*   - attaching specific callback function to handle interrupt source
-*   - master enable/disable
-*   - single callback per interrupt or all pending interrupts handled for
-*     each interrupt of the processor
-*
-* The acknowledgement of the interrupt within the interrupt controller is
-* selectable, either prior to the device's handler being called or after
-* the handler is called. This is necessary to support interrupt signal inputs
-* which are either edge or level signals.  Edge driven interrupt signals
-* require that the interrupt is acknowledged prior to the interrupt being
-* serviced in order to prevent the loss of interrupts which are occurring
-* extremely close together.  A level driven interrupt input signal requires
-* the interrupt to acknowledged after servicing the interrupt to ensure that
-* the interrupt only generates a single interrupt condition.
-*
-* Details about connecting the interrupt handler of the driver are contained
-* in the source file specific to interrupt processing, xintc_intr.c.
-*
-* This driver is intended to be RTOS and processor independent.  It works with
-* physical addresses only.  Any needs for dynamic memory management, threads
-* or thread mutual exclusion, virtual memory, or cache control must be
-* satisfied by the layer above this driver.
-*
-* <b>Interrupt Vector Tables</b>
-*
-* The interrupt vector table for each interrupt controller device is declared
-* statically in xintc_g.c within the configuration data for each instance.
-* The device ID of the interrupt controller device is used by the driver as a
-* direct index into the configuration data table - to retrieve the vector table
-* for an instance of the interrupt controller. The user should populate the
-* vector table with handlers and callbacks at run-time using the XIntc_Connect()
-* and XIntc_Disconnect() functions.
-*
-* Each vector table entry corresponds to a device that can generate an
-* interrupt. Each entry contains an interrupt handler function and an argument
-* to be passed to the handler when an interrupt occurs.  The tools default this
-* argument to the base address of the interrupting device.  Note that the
-* device driver interrupt handlers given in this file do not take a base
-* address as an argument, but instead take a pointer to the driver instance.
-* This means that although the table is created statically, the user must still
-* use XIntc_Connect() when the interrupt handler takes an argument other than
-* the base address. This is only to say that the existence of the static vector
-* tables should not mislead the user into thinking they no longer need to
-* register/connect interrupt handlers with this driver.

-* MODIFICATION HISTORY:
-*
-* Ver   Who  Date     Changes
-* ----- ---- -------- -------------------------------------------------------
-* 1.00a ecm  08/16/01 First release
-* 1.00a rpm  01/09/02 Removed the AckLocation argument from XIntc_Connect().
-*                     This information is now internal in xintc_g.c.
-* 1.00b jhl  02/13/02 Repartitioned the driver for smaller files
-* 1.00b jhl  04/24/02 Made LookupConfig function global and relocated config
-*                     data type
-* 1.00c rpm  10/17/03 New release. Support the static vector table created
-*                     in the xintc_g.c configuration table. Moved vector
-*                     table and options out of instance structure and into
-*                     the configuration table.
-* 1.10c mta  03/21/07 Updated to new coding style
-* 1.11a sv   11/21/07 Updated driver to support access through a DCR bridge
-* 2.00a ktn  10/20/09 Updated to use HAL Processor APIs and _m is removed from
-*		      all the macro names/definitions.
-* 2.01a sdm  04/27/10 Updated the tcl so that the defintions are generated in
-*		      the xparameters.h to know whether the optional registers
-*		      SIE, CIE and IVR are enabled in the HW - Refer CR 555392.
-*		      This driver doesnot make use of these definitions and does
-*		      not use the optional registers.

-*		      interrupts. CR565336
-* 2.04a bss  01/13/12 Added XIntc_ConnectFastHandler API for Fast Interrupt
-*		      and XIntc_SetNormalIntrMode for setting to normal
-*		      interrupt mode.
-* 2.04a asa  03/19/12 Changed the XIntc_Config struct. The order of entries
-*		      declared in the structure now matches with the
-*		      XIntc_ConfigTable generated by the driver tcl.
-* 2.05a bss  08/16/12 Updated to support relocatable vectors in Microblaze,
-*		      added IntVectorAddr to XIntc_Config for this.
-*		      Added XIntc_RegisterFastHandler API to register fast
-*		      interrupt handlers using base address.

-*		      API in xintc_l.c.
-*		      Modified XIntc_SetOptions API in xintc_options.c.
-*		      Modified XIntc_SimulateIntr API in xintc_selftest.c.
-*		      Modified driver tcl:
-*			to check for Cascade mode and generate XPAR_INTC_TYPE
-*			for each controller.
-*			Generate XPAR_INTC_MAX_NUM_INTR_INPUTS by adding all
-*			interrupt sources of all Controllers in Cascade mode.
-* 2.07a bss  10/18/13 To support Nested interrupts:

-*		      Modified driver tcl to generate XPAR_AXI_INTC_0_TYPE
-*		      correctly(CR#764865).
-*
-* @note
-*		For Cascade mode, Interrupt IDs are generated in xparameters.h
-*		as shown below:
-*
-*	    Master/Primary INTC

-*
-*		All driver functions has to be called using DeviceId/
-*		InstancePtr/BaseAddress of Primary/Master Controller and
-*		Interrupts IDs generated in xparameters.h only.
-*		Driver functions takes care of Slave Controllers based on
-*		Interrupt ID passed. User must not use Interrupt source/ID
-*		31 of Primary and Secondary controllers to call driver
-*		functions.
-*
-*		For nested interrupts, XIntc_DeviceInterruptHandler saves
-*		microblaze r14 register on entry and restores on exit. This is
-*		required since compiler does not support nesting. It enables
-*		Microblaze interrupts after blocking further interrupts from
-*		the current interrupt number and interrupts below current
-*		interrupt proirity by writing to Interrupt Level Register of
-*		INTC on entry. On exit, it disables microblaze interrupts and
-*		restores ILR register default value(0xFFFFFFFF)back. It is
-*		recommended to increase STACK_SIZE in linker script for nested
-*		interrupts.
-* 3.0     adk    12/10/13  Updated as per the New Tcl API's
-* 3.0 	  adk 	 17/02/14  Fixed the CR:771287 Changes are made in the intc
-* 		           driver tcl.
-* 3.1     adk    8/4/14    Fixed the CR:783248 Changes are made in
-*			   the test-app tcl
-* 3.2     bss    4/8/14    Fixed driver tcl to handle external interrupt pins
-*			   correctly (CR#799609).
-* 3.3     adk    11/3/14   added generation of C_HAS_ILR parameter to
-*			   xparameters.h.Changes are made in the driver tcl file
-*			   (CR#828046).

-* processing is partitioned seperately such that users are not required to
-* use the provided interrupt processing.  This file requires other files of
-* the driver to be linked in also.
-*
-* Two different interrupt handlers are provided for this driver such that the
-* user must select the appropriate handler for the application.  The first
-* interrupt handler, XIntc_VoidInterruptHandler, is provided for systems
-* which use only a single interrupt controller or for systems that cannot
-* otherwise provide an argument to the XIntc interrupt handler (e.g., the RTOS
-* interrupt vector handler may not provide such a facility).  The constant
-* XPAR_INTC_SINGLE_DEVICE_ID must be defined for this handler to be included in
-* the driver.  The second interrupt handler, XIntc_InterruptHandler, uses an
-* input argument which is an instance pointer to an interrupt controller driver
-* such that multiple interrupt controllers can be supported.  This handler
-* requires the calling function to pass it the appropriate argument, so another
-* level of indirection may be required.
-*
-* Note that both of these handlers are now only provided for backward
-* compatibility. The handler defined in xintc_l.c is the recommended handler.
-*
-* The interrupt processing may be used by connecting one of the interrupt
-* handlers to the interrupt system.  These handlers do not save and restore
-* the processor context but only handle the processing of the Interrupt
-* Controller.  The two handlers are provided as working examples. The user is
-* encouraged to supply their own interrupt handler when performance tuning is
-* deemed necessary.

-* This driver assumes that the context of the processor has been saved prior to
-* the calling of the Interrupt Controller interrupt handler and then restored
-* after the handler returns. This requires either the running RTOS to save the
-* state of the machine or that a wrapper be used as the destination of the
-* interrupt vector to save the state of the processor and restore the state
-* after the interrupt handler returns.

-* Also see the discussion of the interrupt vector tables in xintc.h.
-*
-* There are currently two interrupt handlers specified in this interface.
-*
-* - XIntc_LowLevelInterruptHandler() is a handler without any arguments that
-*   is used in cases where there is a single interrupt controller device in
-*   the system and the handler cannot be passed an argument. This function is
-*   provided mostly for backward compatibility.
-*
-* - XIntc_DeviceInterruptHandler() is a handler that takes a device ID as an
-*   argument, indicating which interrupt controller device in the system is
-*   causing the interrupt - thereby supporting multiple interrupt controllers.

-<div class="textblock"><p>The Xilinx Dual Channel Fifo driver component. This driver supports the Virtex-5(TM) and Virtex-4(TM) XPS_ll_Fifo and the AxiFifo.</p>
-<p>For a full description of the bridge features, please see the HW spec. This driver supports the following features:</p><ul>
-<li>Memory mapped access to host interface registers</li>
-<li>API for polled frame transfers</li>
-<li>API for interrupt driven frame transfers</li>
-<li>Virtual memory support</li>
-<li>Full duplex operation</li>
-</ul>
-<h2>Driver Description</h2>
-<p>This driver enables higher layer software to access the XPS_llFifo core using any alignment in the data buffers.</p>
-<p>This driver supports send and receive channels in the same instance structure in the same fashion as the hardware core.</p>
-<h2>Initialization</h2>
-<p>An instance of this driver is initialized using a call to Initialize().</p>
-<h2>Usage</h2>
-<p>It is fairly simple to use the API provided by this FIFO driver. The only somewhat tricky part is that the calling code must correctly call a couple routines in the right sequence for receive and transmit.</p>
-<p>This sequence is described here. Check the routine functional descriptions for information on how to use a specific API routine.</p>
-<h3>Receive</h3>
-<p>A frame is received by using the following sequence:<br />
- 1) call <a class="el" href="group__llfifo__v5__0.html#ga12da547aa1c9a85e2b0b151f438ff9d5" title="XLlFifo_RxOccupancy returns the number of 32-bit words available (occupancy) to be read from the rece...">XLlFifo_RxOccupancy()</a> to check the occupancy count<br />
- 2) call <a class="el" href="group__llfifo__v5__0.html#ga53af32ae6901462cc8d6fb9adc04655e" title="XLlFifo_RxGetLen notifies the hardware that the program is ready to receive the next frame from the r...">XLlFifo_RxGetLen()</a> to get the length of the next incoming frame<br />
- 3) call <a class="el" href="group__llfifo__v5__0.html#gaadc3685592b060c0d864850e86be5c03" title="XLlFifo_Read reads Bytes bytes from the receive channel of the FIFO referenced by InstancePtr to the ...">XLlFifo_Read()</a> one or more times to read the number of bytes reported by <a class="el" href="group__llfifo__v5__0.html#ga53af32ae6901462cc8d6fb9adc04655e" title="XLlFifo_RxGetLen notifies the hardware that the program is ready to receive the next frame from the r...">XLlFifo_RxGetLen()</a>.<br />
-</p>
-<p>For example: </p><pre>
- 	while (<a class="el" href="group__llfifo__v5__0.html#ga12da547aa1c9a85e2b0b151f438ff9d5" title="XLlFifo_RxOccupancy returns the number of 32-bit words available (occupancy) to be read from the rece...">XLlFifo_RxOccupancy(&amp;RxInstance)</a>) {
- 		frame_len = <a class="el" href="group__llfifo__v5__0.html#ga53af32ae6901462cc8d6fb9adc04655e" title="XLlFifo_RxGetLen notifies the hardware that the program is ready to receive the next frame from the r...">XLlFifo_RxGetLen(&amp;RxInstance)</a>;
-		while (frame_len) {
- 			unsigned bytes = min(sizeof(buffer), frame_len);
- 			<a class="el" href="group__llfifo__v5__0.html#gaadc3685592b060c0d864850e86be5c03" title="XLlFifo_Read reads Bytes bytes from the receive channel of the FIFO referenced by InstancePtr to the ...">XLlFifo_Read(&amp;RxInstance, buffer, bytes)</a>;
- 			// ********
- 			// do something with buffer here
- 			// ********
- 			frame_len -= bytes;
-		}
- 	}
- </pre><p>This FIFO hardware core does <b>not</b> support a sequence where the calling code calls RxGetLen() twice in a row and then receive the data for two frames. Each frame must be read in by calling RxGetLen() just prior to reading the data.</p>
-<h3>Transmit</h3>
-<p>A frame is transmittted by using the following sequence:<br />
- 1) call <a class="el" href="group__llfifo__v5__0.html#ga1fa93f486abaaf35c7d599a8cd91b295" title="XLlFifo_Write writes Bytes bytes of the block of memory, referenced by BufPtr, to the transmit channe...">XLlFifo_Write()</a> one or more times to write all the of bytes in the next frame.<br />
- 2) call <a class="el" href="group__llfifo__v5__0.html#gacd09ed5189e0b85994901102655964f7" title="XLlFifo_TxSetLen begins a hardware transfer of Bytes bytes out of the transmit channel of the FIFO sp...">XLlFifo_TxSetLen()</a> to begin the transmission of frame just written.<br />
-</p>
-<p>For example: </p><pre>
- 	frame_left = frame_len;
- 	while (frame_left) {
- 		unsigned bytes = min(sizeof(buffer), frame_left);
- 		<a class="el" href="group__llfifo__v5__0.html#ga1fa93f486abaaf35c7d599a8cd91b295" title="XLlFifo_Write writes Bytes bytes of the block of memory, referenced by BufPtr, to the transmit channe...">XLlFifo_Write(&amp;TxInstance, buffer, bytes)</a>;
- 		// ********
- 		// do something here to refill buffer
- 		// ********
- 		frame_left -= bytes;
- 	}
- 	<a class="el" href="group__llfifo__v5__0.html#gacd09ed5189e0b85994901102655964f7" title="XLlFifo_TxSetLen begins a hardware transfer of Bytes bytes out of the transmit channel of the FIFO sp...">XLlFifo_TxSetLen(&amp;RxInstance, frame_len)</a>;
- </pre><p>This FIFO hardware core does <b>not</b> support a sequence where the calling code writes the data for two frames and then calls TxSetLen() twice in a row. Each frame must be written by writting the data for one frame and then calling TxSetLen().</p>
-<h2>Interrupts</h2>
-<p>This driver does not handle interrupts from the FIFO hardware. The software layer above may make use of the interrupts by setting up its own handlers for the interrupts.</p>
-<pre>
- MODIFICATION HISTORY:</pre><pre> Ver   Who  Date     Changes
- ----- ---- -------- -------------------------------------------------------
- 1.00a jvb  10/12/06 First release
- 1.01a sdm  08/22/08 Removed support for static interrupt handlers from the
-		       MDD file
- 1.02a jz   12/04/09 Hal phase 1 support
- 2.01a asa  09/17/10 Added code for resetting Local Link/AXI Streaming
-		       interface for CR574868
- 2.02a asa  12/27/11 Changed the function XStrm_Read in xtreamer.c to reset
-		       HeadIndex to zero when all bytes have been read.
-		       Changed the macro XStrm_IsRxInternalEmpty in file
-		       xtreamer.h to use FrmByteCnt instead of HeadIndex.
-		       When FrmByteCnt is zero, this means all internal buffers
-		       in streamer are empty. Earlier implementation using
-		       HeadIndex was not very clear and could give improper
-		       results for some cases.
-		       Changed the macro XLlFifo_IsRxEmpty in file <a class="el" href="xllfifo_8h.html">xllfifo.h</a>
-		       These changes are done to fix the CR 604650.
-  2.03a asa  14/08/12  Added XLLF_TDR_OFFSET, XLLF_RDR_OFFSET
-		         defines for the new registers, and XLLF_INT_TFPF_MASK,
-		         XLLF_INT_TFPE_MASK, XLLF_INT_RFPF_MASK and
-		         XLLF_INT_RFPE_MASK for the new version of the
-		         AXI4-Stream FIFO core (v2.01a and later)</pre><pre> 3.00a adk 08/10/13 Added support for AXI4 Datainterface.Changes are
- 		      In <a class="el" href="xllfifo_8c.html">Xllfifo.c</a> file XLlFifo_RxGetWord,XLlFifo_TxPutword.
- 		      In <a class="el" href="xllfifo_8h.html">XLlfifo.h</a> file updated XLlfifo structure for
- 		      Axi4BaseAddress and for Datainterface type provided
-		      polling and interrupt examples. XLlfifo_IsRxDone Macro
-		      Is added in the <a class="el" href="xllfifo_8h.html">XLlfifo.h</a> file for polledmode exmaple.
-		      Added Static initialzation for the driver.
-		      XLlFifo_Initialize is still used to make the driver
-		      backward compatible.
- 4.0   adk  19/12/13 Updated as per the New Tcl API's
- 5.0   adk  15/05/15 Updated the register offsets in the AXI4 data path
-		       as per latest IP version(v4.1)(CR:860254).</pre><pre> </pre> </div></div><!-- contents -->

- * Implementation Notes:
- *
- * This Fifo driver makes use of a byte streamer driver (xstreamer.h). The code
- * is structured like so:
- *
- * +--------------------+
- * |     llfifo        |
- * |   +----------------+
- * |   | +--------------+
- * |   | |  xstreamer   |

- * |   +----------------+
- * |                    |
- * +--------------------+
- *
- * Initialization
- * At initialization time this driver (llfifo) sets up the streamer objects to
- * use routines in this driver (llfifo) to perform the actual I/O to the H/W
- * FIFO core.
- *
- * Operation
- * Once the streamer objects are set up, the API routines in this driver, just
- * call through to the streamer driver to perform the read/write operations.
- * The streamer driver will eventually make calls back into the routines (which
- * reside in this driver) given at initialization to peform the actual I/O.
- *
- * Interrupts
- * Interrupts are handled in the OS/Application layer above this driver.

- *
- * The Xilinx Dual Channel Fifo driver component. This driver supports the
- * Virtex-5(TM) and Virtex-4(TM) XPS_ll_Fifo and the AxiFifo.
- *
- * For a full description of the bridge features, please see the HW spec. This
- * driver supports the following features:
- *   - Memory mapped access to host interface registers
- *   - API for polled frame transfers
- *   - API for interrupt driven frame transfers
- *   - Virtual memory support
- *   - Full duplex operation
- *
- * <h2>Driver Description</h2>
- *
- * This driver enables higher layer software to access the XPS_llFifo core
- * using any alignment in the data buffers.
- *
- * This driver supports send and receive channels in the same instance
- * structure in the same fashion as the hardware core.
- *
- * <h2>Initialization</h2>
- *
- * An instance of this driver is initialized using a call to Initialize().
- *
- * <h2>Usage</h2>
- *
- * It is fairly simple to use the API provided by this FIFO driver. The
- * only somewhat tricky part is that the calling code must correctly call
- * a couple routines in the right sequence for receive and transmit.
- *
- * This sequence is described here. Check the routine functional
- * descriptions for information on how to use a specific API routine.
- *
- * <h3>Receive</h3>
- *
- * A frame is received by using the following sequence:<br>
- * 1) call XLlFifo_RxOccupancy() to check the occupancy count<br>
- * 2) call XLlFifo_RxGetLen() to get the length of the next incoming frame<br>
- * 3) call XLlFifo_Read() one or more times to read the number of bytes
- *    reported by XLlFifo_RxGetLen().<br>
- *
- * For example:
- * <pre>
- * 	while (XLlFifo_RxOccupancy(&RxInstance)) {
- * 		frame_len = XLlFifo_RxGetLen(&RxInstance);
- *		while (frame_len) {
- * 			unsigned bytes = min(sizeof(buffer), frame_len);
- * 			XLlFifo_Read(&RxInstance, buffer, bytes);
- * 			// ********
- * 			// do something with buffer here
- * 			// ********
- * 			frame_len -= bytes;
- *		}
- * 	}
- * </pre>
- *
- * This FIFO hardware core does <b>not</b> support a sequence where the
- * calling code calls RxGetLen() twice in a row and then receive the data
- * for two frames. Each frame must be read in by calling RxGetLen() just
- * prior to reading the data.
- *
- * <h3>Transmit</h3>
- * A frame is transmittted by using the following sequence:<br>
- * 1) call XLlFifo_Write() one or more times to write all the of bytes in
- *    the next frame.<br>
- * 2) call XLlFifo_TxSetLen() to begin the transmission of frame just
- *    written.<br>
- *
- * For example:
- * <pre>
- * 	frame_left = frame_len;
- * 	while (frame_left) {
- * 		unsigned bytes = min(sizeof(buffer), frame_left);
- * 		XLlFifo_Write(&TxInstance, buffer, bytes);
- * 		// ********
- * 		// do something here to refill buffer
- * 		// ********
- * 		frame_left -= bytes;
- * 	}
- * 	XLlFifo_TxSetLen(&RxInstance, frame_len);
- * </pre>
- *
- * This FIFO hardware core does <b>not</b> support a sequence where the
- * calling code writes the data for two frames and then calls TxSetLen()
- * twice in a row. Each frame must be written by writting the data for one
- * frame and then calling TxSetLen().
- *
- * <h2>Interrupts</h2>
- * This driver does not handle interrupts from the FIFO hardware. The
- * software layer above may make use of the interrupts by setting up its
- * own handlers for the interrupts.
- *
- * <pre>
- * MODIFICATION HISTORY:
- *
- * Ver   Who  Date     Changes
- * ----- ---- -------- -------------------------------------------------------
- * 1.00a jvb  10/12/06 First release
- * 1.01a sdm  08/22/08 Removed support for static interrupt handlers from the
- *		       MDD file
- * 1.02a jz   12/04/09 Hal phase 1 support
- * 2.01a asa  09/17/10 Added code for resetting Local Link/AXI Streaming
- *		       interface for CR574868
- * 2.02a asa  12/27/11 Changed the function XStrm_Read in xtreamer.c to reset
- *		       HeadIndex to zero when all bytes have been read.
- *		       Changed the macro XStrm_IsRxInternalEmpty in file
- *		       xtreamer.h to use FrmByteCnt instead of HeadIndex.
- *		       When FrmByteCnt is zero, this means all internal buffers
- *		       in streamer are empty. Earlier implementation using
- *		       HeadIndex was not very clear and could give improper
- *		       results for some cases.
- *		       Changed the macro XLlFifo_IsRxEmpty in file xllfifo.h
- *		       These changes are done to fix the CR 604650.
-  * 2.03a asa  14/08/12  Added XLLF_TDR_OFFSET, XLLF_RDR_OFFSET
- *		         defines for the new registers, and XLLF_INT_TFPF_MASK,
- *		         XLLF_INT_TFPE_MASK, XLLF_INT_RFPF_MASK and
- *		         XLLF_INT_RFPE_MASK for the new version of the
- *		         AXI4-Stream FIFO core (v2.01a and later)
- *
- * 3.00a adk 08/10/13 Added support for AXI4 Datainterface.Changes are
- * 		      In Xllfifo.c file XLlFifo_RxGetWord,XLlFifo_TxPutword.
- * 		      In XLlfifo.h file updated XLlfifo structure for
- * 		      Axi4BaseAddress and for Datainterface type provided
- *		      polling and interrupt examples. XLlfifo_IsRxDone Macro
- *		      Is added in the XLlfifo.h file for polledmode exmaple.
- *		      Added Static initialzation for the driver.
- *		      XLlFifo_Initialize is still used to make the driver
- *		      backward compatible.
- * 4.0   adk  19/12/13 Updated as per the New Tcl API's
- * 5.0   adk  15/05/15 Updated the register offsets in the AXI4 data path
- *		       as per latest IP version(v4.1)(CR:860254).

- * Implementation Notes
- *
- * --- Receive ---
- *
- * The basic algorithm for receiving bytes through this byte streamer copies a
- * fifo key-hole width chunk from the fifo into a holding buffer and then doles
- * out the bytes from the holding buffer. In some cases, when the buffer given
- * happens to already be aligned in memory, this algorithm will bypass the
- * holding buffer.
- *
- * Here is a picture to depict this process:
- *
- * Initial state:                 holding buffer
- *                                +--------------+

- *                                               ^
- *                                               |
- *                                             index
- *
- * during XStrm_Read():
- * first holding buffer fill:     holding buffer

- * --- Transmit ---
- *

- * when it is full.  In some cases, when the buffer given happens to already be
- * aligned in memory, this algorithm will bypass the holding buffer.

-* @{
- *
- * The Xilinx byte streamer for packet FIFOs.
- *
- * <h2>Driver Description</h2>
- *
- * This driver enables higher layer software to access a hardware FIFO using
- * any alignment in the data buffers while preserving alignment for the hardware
- * FIFO access.
- *
- * This driver treats send and receive channels separately, using different
- * types of instance objects for each.
- *
- * This driver makes use of another FIFO driver to access the specific FIFO
- * hardware through use of the routines passed into the Tx/RxInitialize
- * routines.
- *
- * <h2>Initialization</h2>
- *
- * Send and receive channels are intialized separately. The receive channel is
- * initiailzed using XStrm_RxInitialize(). The send channel is initialized
- * using XStrm_TxInitialize().
- *
- *
- * <h2>Usage</h2>
- * It is fairly simple to use the API provided by this byte streamer
- * driver. The only somewhat tricky part is that the calling code must
- * correctly call a couple routines in the right sequence for receive and
- * transmit.
- *
- * 	This sequence is described here. Check the routine functional
- * descriptions for information on how to use a specific API routine.
- *
- * <h3>Receive</h3>
- * A frame is received by using the following sequence:<br>
- * 1) call XStrm_RxGetLen() to get the length of the next incoming frame.<br>
- * 2) call XStrm_Read() one or more times to read the number of bytes
- * 	   reported by XStrm_RxGetLen().<br>
- *
- * For example:
- * <pre>
- * 	frame_len = XStrm_RxGetLen(&RxInstance);
- * 	while (frame_len) {
- * 		unsigned bytes = min(sizeof(buffer), frame_len);
- * 		XStrm_Read(&RxInstance, buffer, bytes);
- * 		// do something with buffer here
- * 		frame_len -= bytes;
- * 	}
- * </pre>
- *
- * Other restrictions on the sequence of API calls may apply depending on
- * the specific FIFO driver used by this byte streamer driver.
- *
- * <h3>Transmit</h3>
- * A frame is transmittted by using the following sequence:<br>
- * 1) call XStrm_Write() one or more times to write all the of bytes in
- *    the next frame.<br>
- * 2) call XStrm_TxSetLen() to begin the transmission of frame just
- *    written.<br>
- *
- * For example:
- * <pre>
- * 	frame_left = frame_len;
- * 	while (frame_left) {
- * 		unsigned bytes = min(sizeof(buffer), frame_left);
- * 		XStrm_Write(&TxInstance, buffer, bytes);
- * 		// do something here to refill buffer
- * 	}
- * 	XStrm_TxSetLen(&RxInstance, frame_len);
- * </pre>
- *
- * Other restrictions on the sequence of API calls may apply depending on
- * the specific FIFO driver used by this byte streamer driver.
- *
- * <pre>
- * MODIFICATION HISTORY:
- *
- * Ver   Who  Date     Changes

-<div class="textblock"><p>The Xilinx timer/counter component. This component supports the Xilinx timer/counter. More detailed description of the driver operation can be found in the <a class="el" href="xtmrctr_8c.html">xtmrctr.c</a> file.</p>
-<p>The Xilinx timer/counter supports the following features:</p><ul>
-<li>Polled mode.</li>
-<li>Interrupt driven mode</li>
-<li>enabling and disabling specific timers</li>
-<li>PWM operation</li>
-<li>Cascade Operation (This is to be used for getting a 64 bit timer and this feature is present in the latest versions of the axi_timer IP)</li>
-</ul>
-<p>The driver does not currently support the PWM operation of the device.</p>
-<p>The timer counter operates in 2 primary modes, compare and capture. In either mode, the timer counter may count up or down, with up being the default.</p>
-<p>Compare mode is typically used for creating a single time period or multiple repeating time periods in the auto reload mode, such as a periodic interrupt. When started, the timer counter loads an initial value, referred to as the compare value, into the timer counter and starts counting down or up. The timer counter expires when it rolls over/under depending upon the mode of counting. An external compare output signal may be configured such that a pulse is generated with this signal when it hits the compare value.</p>
-<p>Capture mode is typically used for measuring the time period between external events. This mode uses an external capture input signal to cause the value of the timer counter to be captured. When started, the timer counter loads an initial value, referred to as the compare value,</p>
-<p>The timer can be configured to either cause an interrupt when the count reaches the compare value in compare mode or latch the current count value in the capture register when an external input is asserted in capture mode. The external capture input can be enabled/disabled using the XTmrCtr_SetOptions function. While in compare mode, it is also possible to drive an external output when the compare value is reached in the count register The external compare output can be enabled/disabled using the XTmrCtr_SetOptions function.</p>
-<p><b>Interrupts</b></p>
-<p>It is the responsibility of the application to connect the interrupt handler of the timer/counter to the interrupt source. The interrupt handler function, XTmrCtr_InterruptHandler, is visible such that the user can connect it to the interrupt source. Note that this interrupt handler does not provide interrupt context save and restore processing, the user must perform this processing.</p>
-<p>The driver services interrupts and passes timeouts to the upper layer software through callback functions. The upper layer software must register its callback functions during initialization. The driver requires callback functions for timers.</p>
-<dl class="section note"><dt>Note</dt><dd>The default settings for the timers are:<ul>
-<li>Interrupt generation disabled</li>
-<li>Count up mode</li>
-<li>Compare mode</li>
-<li>Hold counter (will not reload the timer)</li>
-<li>External compare output disabled</li>
-<li>External capture input disabled</li>
-<li>Pulse width modulation disabled</li>
-<li>Timer disabled, waits for Start function to be called <br />
-<br />
- A timer counter device may contain multiple timer counters. The symbol XTC_DEVICE_TIMER_COUNT defines the number of timer counters in the device. The device currently contains 2 timer counters. <br />
-<br />
- This driver is intended to be RTOS and processor independent. It works with physical addresses only. Any needs for dynamic memory management, threads or thread mutual exclusion, virtual memory, or cache control must be satisfied by the layer above this driver.</li>

-MODIFICATION HISTORY:</pre><pre>Ver   Who  Date     Changes
------ ---- -------- -----------------------------------------------
-1.00a ecm  08/16/01 First release
-1.00b jhl  02/21/02 Repartitioned the driver for smaller files
-1.10b mta  03/21/07 Updated to new coding style.
-1.11a sdm  08/22/08 Removed support for static interrupt handlers from the MDD
-      	      file
-2.00a ktn  10/30/09 Updated to use HAL API's. _m is removed from all the macro
-      	      definitions.
-2.01a ktn  07/12/10 Renamed the macro XTimerCtr_ReadReg as XTmrCtr_ReadReg
-      	      for naming consistency (CR 559142).
-2.02a sdm  09/28/10 Updated the driver tcl to generate the xparameters
-      	      for the timer clock frequency (CR 572679).
-2.03a rvo  11/30/10 Added check to see if interrupt is enabled before further
-      	      processing for CR 584557.
-2.04a sdm  07/12/11 Added support for cascade mode operation.
-		      The cascade mode of operation is present in the latest
-      	      versions of the axi_timer IP. Please check the HW
-      	      Datasheet to see whether this feature is present in the
-      	      version of the IP that you are using.
-2.05a adk  15/05/13 Fixed the CR:693066
-      	      Added the IsStartedTmrCtr0/IsStartedTmrCtr1 members to the
-      	      <a class="el" href="struct_x_tmr_ctr.html" title="The XTmrCtr driver instance data. ">XTmrCtr</a> instance structure.
-      	      The IsStartedTmrCtrX will be assigned XIL_COMPONENT_IS_STARTED in
-      	      the XTmrCtr_Start function.
-      	      The IsStartedTmrCtrX will be cleared in the XTmrCtr_Stop function.
-      	      There will be no Initialization done in the
-      	      XTmrCtr_Initialize if both the timers have already started and
-      	      the XST_DEVICE_IS_STARTED Status is returned.
-      	      Removed the logic in the XTmrCtr_Initialize function
-      	      which was checking the Register Value to know whether
-      	      a timer has started or not.
-3.0   adk  19/12/13 Updated as per the New Tcl API's
-4.0   als  09/30/15 Updated initialization API.

-* @param	TmrCtrInstancePtr is a pointer to the XTmrCtr driver Instance
-* @param	DeviceId is the XPAR_<TmrCtr_instance>_DEVICE_ID value from

-*
-* @return
-*		- XST_SUCCESS if the Test is successful

-* @{
-* @details
-*
-* The Xilinx timer/counter component. This component supports the Xilinx
-* timer/counter. More detailed description of the driver operation can
-* be found in the xtmrctr.c file.
-*
-* The Xilinx timer/counter supports the following features:
-*   - Polled mode.
-*   - Interrupt driven mode
-*   - enabling and disabling specific timers
-*   - PWM operation
-*   - Cascade Operation (This is to be used for getting a 64 bit timer and this
-*     feature is present in the latest versions of the axi_timer IP)
-*
-* The driver does not currently support the PWM operation of the device.
-*
-* The timer counter operates in 2 primary modes, compare and capture. In
-* either mode, the timer counter may count up or down, with up being the
-* default.
-*
-* Compare mode is typically used for creating a single time period or multiple
-* repeating time periods in the auto reload mode, such as a periodic interrupt.
-* When started, the timer counter loads an initial value, referred to as the
-* compare value, into the timer counter and starts counting down or up. The
-* timer counter expires when it rolls over/under depending upon the mode of
-* counting. An external compare output signal may be configured such that a
-* pulse is generated with this signal when it hits the compare value.
-*
-* Capture mode is typically used for measuring the time period between
-* external events. This mode uses an external capture input signal to cause
-* the value of the timer counter to be captured. When started, the timer
-* counter loads an initial value, referred to as the compare value,
-
-* The timer can be configured to either cause an interrupt when the count
-* reaches the compare value in compare mode or latch the current count
-* value in the capture register when an external input is asserted
-* in capture mode. The external capture input can be enabled/disabled using the
-* XTmrCtr_SetOptions function. While in compare mode, it is also possible to
-* drive an external output when the compare value is reached in the count
-* register The external compare output can be enabled/disabled using the
-* XTmrCtr_SetOptions function.
-*
-* <b>Interrupts</b>
-*
-* It is the responsibility of the application to connect the interrupt
-* handler of the timer/counter to the interrupt source. The interrupt
-* handler function, XTmrCtr_InterruptHandler, is visible such that the user
-* can connect it to the interrupt source. Note that this interrupt handler
-* does not provide interrupt context save and restore processing, the user
-* must perform this processing.
-*
-* The driver services interrupts and passes timeouts to the upper layer
-* software through callback functions. The upper layer software must register
-* its callback functions during initialization. The driver requires callback
-* functions for timers.
-*
-* @note
-* The default settings for the timers are:
-*   - Interrupt generation disabled
-*   - Count up mode
-*   - Compare mode
-*   - Hold counter (will not reload the timer)
-*   - External compare output disabled
-*   - External capture input disabled
-*   - Pulse width modulation disabled
-*   - Timer disabled, waits for Start function to be called
-* <br><br>
-* A timer counter device may contain multiple timer counters. The symbol
-* XTC_DEVICE_TIMER_COUNT defines the number of timer counters in the device.
-* The device currently contains 2 timer counters.
-* <br><br>
-* This driver is intended to be RTOS and processor independent. It works with
-* physical addresses only. Any needs for dynamic memory management, threads
-* or thread mutual exclusion, virtual memory, or cache control must be
-* satisfied by the layer above this driver.
-*
-* <pre>
-* MODIFICATION HISTORY:
-*
-* Ver   Who  Date     Changes
-* ----- ---- -------- -----------------------------------------------
-* 1.00a ecm  08/16/01 First release
-* 1.00b jhl  02/21/02 Repartitioned the driver for smaller files
-* 1.10b mta  03/21/07 Updated to new coding style.
-* 1.11a sdm  08/22/08 Removed support for static interrupt handlers from the MDD
-*		      file
-* 2.00a ktn  10/30/09 Updated to use HAL API's. _m is removed from all the macro
-*		      definitions.
-* 2.01a ktn  07/12/10 Renamed the macro XTimerCtr_ReadReg as XTmrCtr_ReadReg
-*		      for naming consistency (CR 559142).
-* 2.02a sdm  09/28/10 Updated the driver tcl to generate the xparameters
-*		      for the timer clock frequency (CR 572679).
-* 2.03a rvo  11/30/10 Added check to see if interrupt is enabled before further
-*		      processing for CR 584557.
-* 2.04a sdm  07/12/11 Added support for cascade mode operation.
-* 		      The cascade mode of operation is present in the latest
-*		      versions of the axi_timer IP. Please check the HW
-*		      Datasheet to see whether this feature is present in the
-*		      version of the IP that you are using.
-* 2.05a adk  15/05/13 Fixed the CR:693066
-*		      Added the IsStartedTmrCtr0/IsStartedTmrCtr1 members to the
-*		      XTmrCtr instance structure.
-*		      The IsStartedTmrCtrX will be assigned XIL_COMPONENT_IS_STARTED in
-*		      the XTmrCtr_Start function.
-*		      The IsStartedTmrCtrX will be cleared in the XTmrCtr_Stop function.
-*		      There will be no Initialization done in the
-*		      XTmrCtr_Initialize if both the timers have already started and
-*		      the XST_DEVICE_IS_STARTED Status is returned.
-*		      Removed the logic in the XTmrCtr_Initialize function
-*		      which was checking the Register Value to know whether
-*		      a timer has started or not.
-* 3.0   adk  19/12/13 Updated as per the New Tcl API's
-* 4.0   als  09/30/15 Updated initialization API.

 This is VILLASnode, a gateway for processing and forwardning simulation data between real-time simulators.
+VILLASnode is a client/server application to connect simulation equipment and software such as:
 
+ - OPAL-RT eMegaSim,
+ - RTDS GTFPGA cards,
+ - Simulink,
+ - LabView,
+ - and FPGA models.
 
-## Documentation
+It's designed with a focus on very low latency to achieve almost realtime exchange of simulation data.
+VILLASnode is used in distributed- and co-simulation scenarios and developed for the field of power grid simulation at the EON Energy Research Center in Aachen, Germany.
 
-The documentation for this software is available at [doc/Mainpage](doc/Mainpage.md).
+## Overview
 
-The full documentation is available at [doc/html/index.html](doc/html/index.html) after running `doxygen` in this directory.
+The project consists of a server daemon and several client modules which are documented here.
 
-You can access the prebuild documentation at: http://134.130.169.32/villas/node/ (available only from ACS *Office network* and *Simulation Network*).
+[TOC]
+
+### Server
+
+The server simply acts as a gateway to forward simulation data from one client to another.
+Furthermore, it collects statistics, monitors the quality of service and handles encryption or tunneling through VPNs.
+
+For optimal performance the server is implemented in low-level C and makes use of several Linux-specific realtime features.
+The primary design goal was to make the behaviour of the system as deterministic as possible.
+
+Therefore, it's advisable to run the server component on a [PREEMPT_RT](https://rt.wiki.kernel.org/index.php/CONFIG_PREEMPT_RT_Patch) patched version of Linux. In our environment, we use Fedora-based distribution which has been stripped to the bare minimum (no GUI, only a few background processes).
+
+The server is a multi-threaded application.
+
+### Clients
+
+There are two types of clients:
+
+1.  The server handles diffrent types of nodes.
+    The most commonly used node-type is the 'socket' type which allows communication over network links (UDP, raw IP, raw Ethernet frames).
+    But there are also other specialized node types to retreive or send data to equipemnt, which is directly connected to or running on the server itself.
+    An example for such a node is the 'gtfpga' type which directly fetches and pushes data to a PCIe card.
+    Or the 'file' type which logs or replays simulation data from the harddisk.
+
+2. An other way to connect simulation equipment is by using a client-application which itself sends the data over the network to VILLASnode.
+   In this scenario, VILLASnode uses the 'socket' node-type to communicate with the client-application.
+
+Usually, new clients / equipemnt should be implemented as a new node-type as part of VILLASnode.
+Using a dedicated client-application which communicates via the 'socket' type is deprecated because it leads to code duplication.

 # Concept
 
-The server is designed around the concept of _nodes_ and _paths_.
+VILLASnode is designed around the concept of _nodes_, _super-nodes_ and _paths_.
 It's the task of the server to forward real-time simulation data between multiple parties.
 In doing so, the server has to perform simple checks and collects statistics.
 From the viewpoint of the communication parters the server is nearly transparent.
 Hence, it's cruical to keep the added overhead as low as possible (in terms of latency).

+Developement is currently coordinated by Steffen Vogel <stvogel@eonerc.rwth-aachen.de> using [GitLab](http://git.rwth-aachen.de/VILLASframework/VILLASnode).

+
+## Programming Paradigm
+
+VILLASnode is currently written in C using the ISO C99 standard.
+Yet, it is heavily structured into modules / plugins and uses a C++-like object oriented style.
+In the future, VILLASnode might switch to lightweight C++.
+
+Main _classes_ in VILLASnode are struct node, struct path, struct hook and struct api_ressource.
+In order to track the life cycle of those objects, each of them has an enum state member.
+The following figure illustrates the state machine which is used:
+
+@diafile states.dia

 ## Shared library: libvillas
 
-VILLASnode is split into a shared library called libvillas and a couple of executables (`villas-server`, `villas-pipe`, `villas-test`, `villas-signal`) which are linked agains the library.

 # Advanced IO {#advio}
 
-@todo
\ No newline at end of file
+__This page is intended for developers only__
+
+Implements an fopen() abstraction allowing reading from URIs.
+
+This file introduces a c library buffered I/O interface to URI reads it supports fopen(), fread(), fgets(), feof(), fclose(), rewind(). Supported functions have identical prototypes to their normal libc namesakes and are preceaded by 'a'.
+
+Using this code you can replace your program's fopen() with afopen() and fread() with afread() and it become possible to read remote streams instead of (only) local files. Local files (ie those that can be directly fopened) will drop back to using the underlying libc implementations.
+
+Advanced IO (ADVIO) is an extension of the standard IO features (STDIO) which can operate on files stored remotely via a variety of different protocols.
+As ADVIO is built upon libcurl, it supports all of [libcurl protocols](https://curl.haxx.se/libcurl/c/CURLOPT_PROTOCOLS.html).
+
+When openeing a file with ADVIO, the file is requested from the remote server and stored as a local temporary file on the disk.
+Subsequent operations use this local copy of the file.
+When closing or flushing the file, the local copy gets checked for modifications and uploaded to the remote.
+ 
+ There are a few points to keep in mind:
+ 
+ - `afflush()` uploads the file contents to its origin URI if it was changed locally.
+ - `afclose()` flushes (and hence uploads) the file only if it has been modified. Modifications are detected by comparing the files SHA1 hashes.
+ 
+## Extensions
+
+The following functions have been added:
+
+- `aupload()` uploads the file irrespectively if it was changed or not.
+- `adownload()` downloads the file and discards any local changes.
+- `auri()` returns a pointer to the URI.
+- `ahash()` returns a pointer to a
+ 
+## Example
+ 
+    #include <advio.h>
+    
+    AFILE *f;
+    char buf[1024];
+    
+    f = afopen("ftp://user:passwd@server/path/to/file.txt", "r");
+    if (!f)
+    	serror("Failed to open file");
+    
+    afread(buf, 1, 1024, f);
+    
+    printf("%s", buf);
+    
+    afclose(f);
+
+## Usage for VILLASnode
+
+VILLASnode uses ADVIO currently for:
+
+- Fetchting the configuration file. This means VILLASnode can be started like `villas-node http://server/config.conf`
+- As source and destination file for the `file` node-type. Please have a look at the example configuration file `etc/advio.conf`.

+VILLASnode can be controlled remotely over a HTTP REST / WebSocket API.
+This page documents this API.
+
+## Transports
+
+The API is accessible via multiple transports:
+
+- via HTTP POST requests
+- via a WebSocket protocol
+- via a Unix socket
+
+All transports use the same JSON based protocol to handle requests.

Subject: [PATCH 210/211] Overhaul of build and packaging system:
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Build RPM packages for VILLASnode and dependencies with the ‚rpm‘, ‚rpm-villas‘, ‚rpm-livxil‘ and ‚rpm-libwebsockets‘ make targets
- Upload new RPM packages to the repository with the ‚deploy‘ make target
- Build a developer Docker image with the `docker-dev` target
- Run the developer image with the `run-docker-dev` target
- Build a production Docker image with the `docker` target
  This requires that all RPM packages have been build previously!
- Use hard-coded default paths where applicable
- Updated index website
- Added some usage information and hints

Documentation of the new system is still outstanding
