Some fixes were suggested, but essentially we should call the move notification before actually moving things because only this way we have the correct order for DMA-buf and VM move notifications as well. Also rework the statistic handling so that we don't update the eviction counter before the move. v2: add missing NULL check Signed-off-by: Christian König <christian.koenig(a)amd.com> Fixes: 94aeb4117343 ("drm/amdgpu: fix ftrace event amdgpu_bo_move always move on same heap") Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/3171 Reviewed-by: Alex Deucher <alexander.deucher(a)amd.com> Signed-off-by: Alex Deucher <alexander.deucher(a)amd.com> CC: stable(a)vger.kernel.org diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_object.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_object.c index 706345ea1430..751443402ced 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_object.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_object.c @@ -1255,14 +1255,18 @@ int amdgpu_bo_get_metadata(struct amdgpu_bo *bo, void *buffer, * amdgpu_bo_move_notify - notification about a memory move * @bo: pointer to a buffer object * @evict: if this move is evicting the buffer from the graphics address space + * @new_mem: new resource for backing the BO * * Marks the corresponding &amdgpu_bo buffer object as invalid, also performs * bookkeeping. * TTM driver callback which is called when ttm moves a buffer. */ -void amdgpu_bo_move_notify(struct ttm_buffer_object *bo, bool evict) +void amdgpu_bo_move_notify(struct ttm_buffer_object *bo, + bool evict, + struct ttm_resource *new_mem) { struct amdgpu_device *adev = amdgpu_ttm_adev(bo->bdev); + struct ttm_resource *old_mem = bo->resource; struct amdgpu_bo *abo; if (!amdgpu_bo_is_amdgpu_bo(bo)) @@ -1274,12 +1278,12 @@ void amdgpu_bo_move_notify(struct ttm_buffer_object *bo, bool evict) amdgpu_bo_kunmap(abo); if (abo->tbo.base.dma_buf && !abo->tbo.base.import_attach && - bo->resource->mem_type != TTM_PL_SYSTEM) + old_mem && old_mem->mem_type != TTM_PL_SYSTEM) dma_buf_move_notify(abo->tbo.base.dma_buf); - /* remember the eviction */ - if (evict) - atomic64_inc(&adev->num_evictions); + /* move_notify is called before move happens */ + trace_amdgpu_bo_move(abo, new_mem ?

The GPU has an unused 4K area of the register BAR space into which you can remap registers. We remap the HDP flush registers into this space to allow userspace (CPU or GPU) to flush the HDP when it updates VRAM. However, on systems with >4K pages, we end up exposing PAGE_SIZE of MMIO space.
