From 96595204195d7e13736a84295e217316610d4cdb Mon Sep 17 00:00:00 2001 From: Srinivasan Shanmugam Date: Mon, 29 Jul 2024 21:35:26 +0530 Subject: drm/amdgpu: Make enforce_isolation setting per GPU MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit makes enforce_isolation setting to be per GPU and per partition by adding the enforce_isolation array to the adev structure. The adev variable is set based on the global enforce_isolation module parameter during device initialization. In amdgpu_ids.c, the adev->enforce_isolation value for the current GPU is used to determine whether to enforce isolation between graphics and compute processes on that GPU. In amdgpu_ids.c, the adev->enforce_isolation value for the current GPU and partition is used to determine whether to enforce isolation between graphics and compute processes on that GPU and partition. This allows the enforce_isolation setting to be controlled individually for each GPU and each partition, which is useful in a system with multiple GPUs and partitions where different isolation settings might be desired for different GPUs and partitions. v2: fix loop in amdgpu_vmid_mgr_init() (Alex) Cc: Christian König Cc: Alex Deucher Signed-off-by: Srinivasan Shanmugam Signed-off-by: Alex Deucher Suggested-by: Christian König --- drivers/gpu/drm/amd/amdgpu/amdgpu_ids.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'drivers/gpu/drm/amd/amdgpu/amdgpu_ids.h') diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_ids.h b/drivers/gpu/drm/amd/amdgpu/amdgpu_ids.h index 240fa6751260..4012fb2dd08a 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_ids.h +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_ids.h @@ -78,7 +78,8 @@ void amdgpu_pasid_free_delayed(struct dma_resv *resv, bool amdgpu_vmid_had_gpu_reset(struct amdgpu_device *adev, struct amdgpu_vmid *id); -bool amdgpu_vmid_uses_reserved(struct amdgpu_vm *vm, unsigned int vmhub); +bool amdgpu_vmid_uses_reserved(struct amdgpu_device *adev, + struct amdgpu_vm *vm, unsigned int vmhub); int amdgpu_vmid_alloc_reserved(struct amdgpu_device *adev, unsigned vmhub); void amdgpu_vmid_free_reserved(struct amdgpu_device *adev, -- cgit v1.2.3
