From 8c505bdc9c8b955223b054e34a0be9c3d841cd20 Mon Sep 17 00:00:00 2001 From: Christian König Date: Wed, 9 Jun 2021 13:51:36 +0200 Subject: drm/amdgpu: rework dma_resv handling v3 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Drop the workaround and instead implement a better solution. Basically we are now chaining all submissions using a dma_fence_chain container and adding them as exclusive fence to the dma_resv object. This way other drivers can still sync to the single exclusive fence while amdgpu only sync to fences from different processes. v3: add the shared fence first before the exclusive one Signed-off-by: Christian König Reviewed-by: Alex Deucher Acked-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20210614174536.5188-2-christian.koenig@amd.com --- drivers/gpu/drm/amd/amdgpu/amdgpu_object.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/gpu/drm/amd/amdgpu/amdgpu_object.c') diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_object.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_object.c index b7a2070d90af..d13490975ac3 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_object.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_object.c @@ -892,7 +892,7 @@ int amdgpu_bo_pin_restricted(struct amdgpu_bo *bo, u32 domain, return -EINVAL; /* A shared bo cannot be migrated to VRAM */ - if (bo->prime_shared_count || bo->tbo.base.import_attach) { + if (bo->tbo.base.import_attach) { if (domain & AMDGPU_GEM_DOMAIN_GTT) domain = AMDGPU_GEM_DOMAIN_GTT; else -- cgit v1.2.3 From ea7acd7c5967542353430947f3faf699e70602e5 Mon Sep 17 00:00:00 2001 From: Andrey Grodzovsky Date: Tue, 22 Jun 2021 12:23:38 -0400 Subject: drm/amdgpu: Fix BUG_ON assert MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit With added CPU domain to placement you can have now 3 placemnts at once.
