From 0385800c2ff7bddf16a9caad5840f4e4823253f2 Mon Sep 17 00:00:00 2001 From: Shashank Sharma Date: Tue, 10 Oct 2023 12:17:44 +0200 Subject: drm/amdgpu: add helpers to create userqueue object This patch introduces amdgpu_userqueue_object and its helper functions to creates and destroy this object. The helper functions creates/destroys a base amdgpu_bo, kmap/unmap it and save the respective GPU and CPU addresses in the encapsulating userqueue object. These helpers will be used to create/destroy userqueue MQD, WPTR and FW areas. V7: - Forked out this new patch from V11-gfx-userqueue patch to prevent that patch from growing very big. - Using amdgpu_bo_create instead of amdgpu_bo_create_kernel in prep for eviction fences (Christian) V9: - Rebase V10: - Added Alex's R-B Cc: Alex Deucher Cc: Christian Koenig Reviewed-by: Alex Deucher Signed-off-by: Shashank Sharma Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/include/amdgpu_userqueue.h | 13 +++++++++++++ 1 file changed, 13 insertions(+) (limited to 'drivers/gpu/drm/amd/include/amdgpu_userqueue.h') diff --git a/drivers/gpu/drm/amd/include/amdgpu_userqueue.h b/drivers/gpu/drm/amd/include/amdgpu_userqueue.h index b739274c72e1..bbd29f68b8d4 100644 --- a/drivers/gpu/drm/amd/include/amdgpu_userqueue.h +++ b/drivers/gpu/drm/amd/include/amdgpu_userqueue.h @@ -29,6 +29,12 @@ struct amdgpu_mqd_prop; +struct amdgpu_userq_obj { + void *cpu_ptr; + uint64_t gpu_addr; + struct amdgpu_bo *obj; +}; + struct amdgpu_usermode_queue { int queue_type; uint64_t doorbell_handle; @@ -37,6 +43,7 @@ struct amdgpu_usermode_queue { struct amdgpu_mqd_prop *userq_prop; struct amdgpu_userq_mgr *userq_mgr; struct amdgpu_vm *vm; + struct amdgpu_userq_obj mqd; }; struct amdgpu_userq_funcs { @@ -60,4 +67,10 @@ int amdgpu_userq_mgr_init(struct amdgpu_userq_mgr *userq_mgr, struct amdgpu_devi void amdgpu_userq_mgr_fini(struct amdgpu_userq_mgr *userq_mgr); +int amdgpu_userqueue_create_object(struct amdgpu_userq_mgr *uq_mgr, + struct amdgpu_userq_obj *userq_obj, + int size); + +void amdgpu_userqueue_destroy_object(struct amdgpu_userq_mgr *uq_mgr, + struct amdgpu_userq_obj *userq_obj); #endif -- cgit v1.2.3
