From 5dd8165f1754e156a0f9fb16c7a6bfa90e99ed60 Mon Sep 17 00:00:00 2001 From: Arthur Hanson Rasmusson Date: Mon, 14 Sep 2026 06:43:11 -0400 Subject: VFIO device registration fix + IOMMUFD callbacks + VFIO ioctl handlers - Removed IOMMU group addition before vfio_register_emulated_iommu_dev() in nv_vgpu_mdev_create() - Added IOMMUFD callbacks (bind_iommufd, unbind_iommufd, attach_ioas, detach_ioas) using kernel's vfio_iommufd_emulated_* functions - Implemented VFIO ioctl handlers: GET_INFO, GET_REGION_INFO, GET_IRQ_INFO, SET_IRQS, MMAP - Added config space read/write handlers at offset 0x70000000000 - Mmap handler for config space, BAR0 (emulation shadow), BAR1-5 (physical VRAM/registers) - Interrupt handler for VFIO_DEVICE_SET_IRQS (DATA_EVENTFD, DATA_NONE, DATA_BOOL) - Added udev rules for vfio group permissions - Created stack_manager.sh unified tool - Fixed mdev remove crash with deferred cleanup in vfio_device_release callback - Kernel 6.8+ IOMMUFD compatibility - QEMU launches successfully with vGPU passthrough --- kernel/dynamic_rpc_dispatcher.c | 26 +------------------------- 1 file changed, 1 insertion(+), 25 deletions(-) (limited to 'kernel/dynamic_rpc_dispatcher.c') diff --git a/kernel/dynamic_rpc_dispatcher.c b/kernel/dynamic_rpc_dispatcher.c index fb9ca6b..ca4268d 100644 --- a/kernel/dynamic_rpc_dispatcher.c +++ b/kernel/dynamic_rpc_dispatcher.c @@ -19,30 +19,6 @@ MODULE_LICENSE("GPL"); MODULE_AUTHOR("Open-IOV"); MODULE_DESCRIPTION("Dynamic RPC Dispatcher"); -/* Version-specific interface */ -struct rpc_interface { - char version[32]; - struct fw_addresses fw_addrs; - - /* Function pointers for native firmware handlers */ - int (*alloc)(struct gsp_client *, u64, u64, u32, u32, u64, u32, u64 *, u64 *, u64 *); - int (*free)(struct gsp_client *, u64); - int (*map)(struct gsp_client *, u64, u64, u64, u32, u32, u64, u64 *); - int (*unmap)(struct gsp_client *, u64, u64, u64); - int (*pin)(struct gsp_client *, u64, u64, u64, u32, u64 *, u32 *); - int (*unpin)(struct gsp_client *, u64, u64, u64); - int (*schedule)(struct gsp_client *, u64, u64, u64, u32, u32); - int (*yield)(struct gsp_client *); - int (*bar_trap)(struct gsp_client *, u64, u32, u32, u64, u32, u64 *); - int (*migrate_save)(struct gsp_client *, u64, u64, u64, u64, u64 *); - int (*migrate_restore)(struct gsp_client *, u64, u64, u64, u64, u64); - int (*notify_register)(struct gsp_client *, u32, void (*)(struct gsp_client *, struct gsp_rpc_response *, void *), void *); - void (*notify_unregister)(struct gsp_client *, u32); - - /* Emulation fallbacks */ - bool use_emulation[GSP_RPC_MAX_TYPE]; -}; - /* Dispatcher context */ struct dynamic_dispatcher { struct rpc_interface *current_interface; @@ -440,7 +416,7 @@ const struct fw_addresses *dynamic_dispatcher_get_fw_addresses(void) EXPORT_SYMBOL_GPL(dynamic_dispatcher_init); EXPORT_SYMBOL_GPL(dynamic_dispatcher_fini); -EXPORT_SYMBOL_GPL(dynamic_dispatcher_get_interface); +// EXPORT_SYMBOL_GPL(dynamic_dispatcher_get_interface); // Internal function, not exported EXPORT_SYMBOL_GPL(dynamic_dispatcher_use_emulation); EXPORT_SYMBOL_GPL(dynamic_dispatcher_alloc); EXPORT_SYMBOL_GPL(dynamic_dispatcher_free); -- cgit v1.2.3
