drm/amdgpu: Reset the clear flag in buddy during resume

2025-08-01T08:48:42+00:00

commit 95a16160ca1d75c66bf7a1c5e0bcaffb18e7c7fc upstream. - Added a handler in DRM buddy manager to reset the cleared flag for the blocks in the freelist. - This is necessary because, upon resuming, the VRAM becomes cluttered with BIOS data, yet the VRAM backend manager believes that everything has been cleared. v2: - Add lock before accessing drm_buddy_clear_reset_blocks()(Matthew Auld) - Force merge the two dirty blocks.(Matthew Auld) - Add a new unit test case for this issue.(Matthew Auld) - Having this function being able to flip the state either way would be good. (Matthew Brost) v3(Matthew Auld): - Do merge step first to avoid the use of extra reset flag.

drm/amdgpu: add a BO metadata flag to disable write compression for Vulkan

2025-02-17T09:05:09+00:00

commit 2255b40cacc2e5ef1b127770fc1808c60de4a2fc upstream. Vulkan can't support DCC and Z/S compression on GFX12 without WRITE_COMPRESS_DISABLE in this commit or a completely different DCC interface. AMDGPU_TILING_GFX12_SCANOUT is added because it's already used by userspace.

drm/amdgpu: Enable clear page functionality

2024-04-22T17:44:16+00:00

Add clear page support in vram memory region. v1(Christian): - Dont handle clear page as TTM flag since when moving the BO back in from GTT again we don't need that. - Make a specialized version of amdgpu_fill_buffer() which only clears the VRAM areas which are not already cleared - Drop the TTM_PL_FLAG_WIPE_ON_RELEASE check in amdgpu_object.c v2: - Modify the function name amdgpu_ttm_* (Alex) - Drop the delayed parameter (Christian) - handle amdgpu_res_cleared(&cursor) just above the size calculation (Christian) - Use AMDGPU_GEM_CREATE_VRAM_WIPE_ON_RELEASE for clearing the buffers in the free path to properly wait for fences etc.. (Christian) v3(Christian): - Remove buffer clear code in VRAM manager instead change the AMDGPU_GEM_CREATE_VRAM_WIPE_ON_RELEASE handling to set the DRM_BUDDY_CLEARED flag. - Remove ! from amdgpu_res_cleared(&cursor) check. v4(Christian): - vres flag setting move to vram manager file - use dma_fence_get_stub in amdgpu_ttm_clear_buffer function - make fence a mandatory parameter and drop the if and the get/put dance Signed-off-by: Arunpravin Paneer Selvam Suggested-by: Christian König Acked-by: Felix Kuehling Link: https://patchwork.freedesktop.org/patch/msgid/20240419063538.11957-2-Arunpravin.PaneerSelvam@amd.com Signed-off-by: Christian König

drm/amdgpu: fix visible VRAM handling during faults

2024-04-17T02:39:15+00:00

When we removed the hacky start code check we actually didn't took into account that *all* VRAM pages needs to be CPU accessible. Clean up the code and unify the handling into a single helper which checks if the whole resource is CPU accessible. The only place where a partial check would make sense is during eviction, but that is neglitible.
