Change Log for Xilkernel
|
|
=================================
|
|
2011-08-22
|
|
version v5_01a
|
|
* init.h, ksched.h, ksemaphore.h, mem.h, process.h, timer.h, xtrace.h,
|
|
xmk.h, libprocess.c, libtimer.c, microblaze/debugmon.c, microblaze/mpu.c,
|
|
microblaze/timer_intr_handler.c, ppc/debugmon.c, ppc/ppc_hw.c, sched.c,
|
|
ppc/timer_intr_handler.c, bufmalloc.c, intr.c, mem.c, process.c, timer.c:
|
|
Removed compilation issues that are found when compiled with
|
|
GCC "-Wstrict-prototype" option. Some of the typical changes made are:
|
|
"void soft_tmr_init();" is changed to "void soft_tmr_init(void);".
|
|
|
|
The main.c at src/sys directory is renamed to xilkernel_main.c to avoid
|
|
conflicts during debugging.
|
|
|
|
include/arch/microblaze/arch.h: Two more regs are added to the process
|
|
context. These new regs will be used only when stack protection is
|
|
enabled in microblaze. Otherwise they will be dummies.
|
|
|
|
include/sys/decls.h: Externs for _ftext, _etext, _fdata, _edata,
|
|
_frodata, _erodata, _stack_end, _stack, _fstack_guard_top,
|
|
_estack_guard_top, _fstack_guard_bottom, and _estack_guard_bottom
|
|
are added.
|
|
|
|
microblaze/entry.S: Code added for saving and restoring the SHR and SLR
|
|
registers when microblaze stack protection is enabled in the hardware.
|
|
|
|
microblaze/hw_exception_handler.S: Code added for the new stack protection
|
|
exception. It is identical to what is present for standalone BSP.
|
|
|
|
microblaze/mpu.c : Vector table is added to the TLB entries, The externs
|
|
for _ftext, _etext, _fdata, _edata,_frodata, _erodata, _stack_end,
|
|
_stack, _fstack_guard_top, _estack_guard_top, _fstack_guard_bottom,
|
|
and _estack_guard_bottom are removed.
|
|
|
|
microblaze/mb-hw.c: In function "setup_initial_context", code added to
|
|
store the stack limits. In function init_idle_task, code added to store
|
|
the stack limits and initialize the SHR and SLR regs. Also MACROs for
|
|
writing to/reading from SHR/SLR regs are added. Changes done in function
|
|
"microblaze_report_exception" to remove warnings. Lines of code added to
|
|
zero out "esr", "ear" and "pc" after they are used. Changes done at
|
|
many places in the file to remove warnings found with GCC
|
|
"-Wstrict-prototype" option. In function "microblaze_report_exception",
|
|
the existing "DPRINTF"s are replaced with xil_printfs.
|
|
|
|
sys/pthread.c: Code added to pass the stacksize while calling
|
|
"setup_initial_context". The stacksize passed is used for microblaze and in
|
|
general can be handy for future enhancements.
|
|
|
|
sys/elf.c: Extra "stacksize" argument added for the "setup_initial_context"
|
|
call.
|
|
|
|
ppc/ppc-hw.c: Extra "stacksize" argument added for the "setup_initial_context"
|
|
call. It is zeroed out to remove compilation warnings.
|
|
|
|
ppc/timer_intr_handler.c: In function "timer_int_handler" the passed argument
|
|
is zeroed out to remove compilation warning.
|
|
|
|
xilkernel_v2_1_0.tcl: Changes done so that function prototypes generated for
|
|
static thread entry functions do not lead to warnings during compilation
|
|
(with GCC "-Wstrict-prototype" option).
|
|
|
|
|
|
|
|
2010-09-14
|
|
* src/src/arch/microblaze/hw_exception_handler.S: Added in xparameters.h
|
|
so that exception enable information is available.

|
|
|
|

|
|
* src/src/arch/microblaze/mb-hw.c, src/src/arch/ppc/ppc-hw.c,
|
|
src/src/sys/main.c, src/include/sys/arch.h: Adapted to work with
|
|
new HAL API from standalone_v3.
|
|
|
|
2010-02-08
|
|
* data/xilkernel_v2_1_0.tcl: Add DRC for pthread stack size.
|
|
|
|
2010-01-27
|
|
* src/include/sys/init.h, src/src/sys/main.c: Protos for
|
|
xilkernel_init and xilkernel_start.

2009-12-17
|
|
* data/xilkernel_v2_1_0.mld, data/xilkernel_v2_1_0.tcl: New
|
|
standalone version. Change dependency to standalone_v3_00_a. Do
|
|
the necessary management of standalone_v3 sources.
|
|
|
|
2008-11-17
|
|
|
|
* src/src/sys/main.c, src/include/sys/init.h: Add new API
|
|
xmk_add_static_thread(). This function can be used prior to
|
|
xilkernel_init() to add startup threads via application code.
|
|
|
|
2008-11-06
|
|
|
|
* data/xilkernel.tcl: Modify TCL iteration of I/O ranges to
|
|
accomodate changes in the the hardware TCL interface.
|
|
|

|
|
|
|
2008-02-20
|
|
|
|
* src/src/sys/alloc.c: Make kernel stack size equal to the greater
|
|
of 1024 bytes or pthread_stack_size. New stack start pointer
|
|
variable used to switch stacks in kernel entry routines.
|
|
* src/include/arch/<processor>/arch.h: Remove KERNEL_IRQ_STACKSZ
|
|
* src/src/arch/<processor>/entry<sub_type>.S: Load new stack
|
|
pointer from kernel_irq_stack_ptr rather than offset from label
|
|
kernel_irq_stack.
|
|
|
|
2007-10-22
|
|
|
|
* data/xilkernel_v2_1_0.mld: Change depends tag to standalone_v2_00_a.
|
|
|
|
2007-10-15
|
|
|
|
* Makefile_mb.sh: Fix regression with compiler used in kernel Make. Always
|
|
use *-gcc
|
|
|
|
* timer.h: Add prototype for xget_clock_ticks
|
|
|
|
2007-09-26
|
|
|
|
* ktypes.h: Add new field 'remain' for storing process timeout information
|
|
|
|
* process.c: When unblocking a process waiting on a timeout, store the
|
|
remaining timeout amount in the process data structure.
|
|
|
|
* semaphore.c: Add sys/timer.h to includes
|
|
|
|
* timer.c: Cleanup prototypes. Add new function to compute ticks_to_ms.
|
|
Store timeout remaining in process data structure. Update to remove_tmr
|
|
on 2007-09-11 was not sufficient. Since the previous scheme required an
|
|
interrupt to deallocate removed timers. It could cause an application to
|
|
run out of timers, before the next interrupt. Created new scheme, where
|
|
active_tmr lists are updated promptly upon a timer being deactivated.
|
|
|
|
* xtrace.c/.h: New xtrace API for internal use. Minimally intrusive way
|
|
to instrument kernel and log events of interest. Log gets printed out
|
|
later through debugger. Not available through MSS.
|
|
|
|
2007-09-19
|
|
|
|
* timer_intr_handler.c/<arch>-hw.c: Fix for bug where threads could starve
|
|
because of the way we always used to refresh PIT timer. Now, when a thread
|
|
receives only a partial tick, the timer is not refreshed and instead the
|
|
thread receives one more full time quantum. cr=448047
|
|
|
|
2007-09-11
|
|
|
|
* timer.c: Fix bug with timer handling of closely scheduled add/remove
|
|
of timers. The changes make sure that no ghost timers are left in the
|
|
timer lists and there are no aliasing effects. cr=448047
|
|
|
|
2014-04-15
|
|
|
|
* modified driver tcl to remove _interrupt_handler.o from libgloss.a
|
|
instead of libxil.a
|
|
|
|
2014-04-29
|
|
|
|
* modified driver tcl to use libxil.a if libgloss.a does not exist
|
|
|
|
2014-06-27
|
|
* Fixed the CR:802962 and the CR:803104 changes are made in the tcl file
|
|
|
|
2014-11-13
|
|
* Fixed CR:828759 Changes are made in the tcl file
