Device drivers take responsibility to fill queue-vec mapping table(vec_num[]). Signed-off-by: Danny Zhou Signed-off-by: Cunming Liang --- v6 changes: - add mapping table between irq vector number and queue id. v5 changes: - Create this new patch file for changed struct rte_intr_handle that other patches depend on, to avoid breaking git bisect. lib/librte_eal/linuxapp/eal/include/exec-env/rte_interrupts.h | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/lib/librte_eal/linuxapp/eal/include/exec-env/rte_interrupts.h b/lib/librte_eal/linuxapp/eal/include/exec-env/rte_interrupts.h index 6a159c7..9f45377 100644 --- a/lib/librte_eal/linuxapp/eal/include/exec-env/rte_interrupts.h +++ b/lib/librte_eal/linuxapp/eal/include/exec-env/rte_interrupts.h @@ -38,6 +38,9 @@ #ifndef _RTE_LINUXAPP_INTERRUPTS_H_ #define _RTE_LINUXAPP_INTERRUPTS_H_ +#define VFIO_MAX_RXTX_INTR_ID 32 +#define VFIO_MAX_QUEUE_ID VFIO_MAX_RXTX_INTR_ID + enum rte_intr_handle_type { RTE_INTR_HANDLE_UNKNOWN = 0, RTE_INTR_HANDLE_UIO, /**< uio device handle */ @@ -48,6 +51,9 @@ enum rte_intr_handle_type { RTE_INTR_HANDLE_MAX }; +#define RTE_INTR_EVENT_ADD 1UL +#define RTE_INTR_EVENT_DEL 2UL + /** Handle for interrupts. */ struct rte_intr_handle { union { @@ -57,6 +63,9 @@ struct rte_intr_handle { }; int fd; /**< interrupt event file descriptor */ enum rte_intr_handle_type type; /**< handle type */ + int max_intr; /**< max interrupt requested */ + int efds[VFIO_MAX_RXTX_INTR_ID]; /**< rxtx intr event fd for vfio */ + uint32_t vec_num[VFIO_MAX_QUEUE_ID]; /**< rxtx intr vector number */ }; #endif /* _RTE_LINUXAPP_INTERRUPTS_H_ */ -- 1.8.1.4
