* MODIFICATION HISTORY: * * Ver Who Date Changes * ----- ---- -------- ----------------------------------------------------- * 1.00a drg 01/19/10 First release * 1.01a sdm 11/09/11 "xil_exception.h" added as include. * Macros XScuGic_EnableIntr and XScuGic_DisableIntr are * added to enable or disable interrupts based on * Distributor Register base address. Normally users use * XScuGic instance and call XScuGic_Enable or * XScuGic_Disable to enable/disable interrupts. These * new macros are provided when user does not want to * use an instance pointer but still wants to enable or * disable interrupts. * Function prototypes for functions (present in newly * added file xscugic_hw.c) are added. * 1.03a srt 02/27/13 Moved Offset calculation macros from *_hw.c (CR * 702687). * 1.04a hk 05/04/13 Fix for CR#705621. Moved function prototypes * XScuGic_SetPriTrigTypeByDistAddr and * XScuGic_GetPriTrigTypeByDistAddr here from xscugic.h * 3.0 pkp 12/09/14 changed XSCUGIC_MAX_NUM_INTR_INPUTS for * Zynq Ultrascale Mp ** ******************************************************************************/ #ifndef XSCUGIC_HW_H /* prevent circular inclusions */ #define XSCUGIC_HW_H /* by using protection macros */ #ifdef __cplusplus extern "C" { #endif /***************************** Include Files *********************************/ #include "xil_types.h" #include "xil_assert.h" #include "xil_io.h" #include "xil_exception.h" /************************** Constant Definitions *****************************/ /* * The maximum number of interrupts supported by the hardware. */ #ifdef __ARM_NEON__ #define XSCUGIC_MAX_NUM_INTR_INPUTS 95U /* Maximum number of interrupt defined by Zynq */ #else #define XSCUGIC_MAX_NUM_INTR_INPUTS 150U /* Maximum number of interrupt defined by Zynq Ultrascale Mp */ #endif /* * The maximum priority value that can be used in the GIC. */ #define XSCUGIC_MAX_INTR_PRIO_VAL 248U #define XSCUGIC_INTR_PRIO_MASK 0x000000F8U /** @name Distributor Interface Register Map * * Define the offsets from the base address for all Distributor registers of * the interrupt controller, some registers may be reserved in the hardware * device. * @{ */ #define XSCUGIC_DIST_EN_OFFSET 0x00000000U /**< Distributor Enable Register */ #define XSCUGIC_IC_TYPE_OFFSET 0x00000004U /**< Interrupt Controller Type Register */ #define XSCUGIC_DIST_IDENT_OFFSET 0x00000008U /**< Implementor ID Register */ #define XSCUGIC_SECURITY_OFFSET 0x00000080U /**< Interrupt Security Register */ #define XSCUGIC_ENABLE_SET_OFFSET 0x00000100U /**< Enable Set Register */ #define XSCUGIC_DISABLE_OFFSET 0x00000180U /**< Enable Clear Register */ #define XSCUGIC_PENDING_SET_OFFSET 0x00000200U /**< Pending Set Register */ #define XSCUGIC_PENDING_CLR_OFFSET 0x00000280U /**< Pending Clear Register */ #define XSCUGIC_ACTIVE_OFFSET 0x00000300U /**< Active Status Register */ #define XSCUGIC_PRIORITY_OFFSET 0x00000400U /**< Priority Level Register */ #define XSCUGIC_SPI_TARGET_OFFSET 0x00000800U /**< SPI Target Register 0x800-0x8FB */ #define XSCUGIC_INT_CFG_OFFSET 0x00000C00U /**< Interrupt Configuration Register 0xC00-0xCFC */ #define XSCUGIC_PPI_STAT_OFFSET 0x00000D00U /**< PPI Status Register */ #define XSCUGIC_SPI_STAT_OFFSET 0x00000D04U /**< SPI Status Register 0xd04-0xd7C */ #define XSCUGIC_AHB_CONFIG_OFFSET 0x00000D80U /**< AHB Configuration Register */ #define XSCUGIC_SFI_TRIG_OFFSET 0x00000F00U /**< Software Triggered Interrupt Register */ #define XSCUGIC_PERPHID_OFFSET 0x00000FD0U /**< Peripheral ID Reg */ #define XSCUGIC_PCELLID_OFFSET 0x00000FF0U /**< Pcell ID Register */ /* @} */ /** @name Distributor Enable Register * Controls if the distributor response to external interrupt inputs. * @{ */ #define XSCUGIC_EN_INT_MASK 0x00000001U /**< Interrupt In Enable */ /* @} */ /** @name Interrupt Controller Type Register * @{ */ #define XSCUGIC_LSPI_MASK 0x0000F800U /**< Number of Lockable Shared Peripheral Interrupts*/ #define XSCUGIC_DOMAIN_MASK 0x00000400U /**< Number os Security domains*/ #define XSCUGIC_CPU_NUM_MASK 0x000000E0U /**< Number of CPU Interfaces */ #define XSCUGIC_NUM_INT_MASK 0x0000001FU /**< Number of Interrupt IDs */ /* @} */ /** @name Implementor ID Register * Implementor and revision information. * @{ */ #define XSCUGIC_REV_MASK 0x00FFF000U /**< Revision Number */ #define XSCUGIC_IMPL_MASK 0x00000FFFU /**< Implementor */ /* @} */ /** @name Interrupt Security Registers * Each bit controls the security level of an interrupt, either secure or non * secure.
