drm/ttm: use per BO cleanup workers

2022-12-06T09:53:20+00:00

Instead of a single worker going over the list of delete BOs in regular intervals use a per BO worker which blocks for the resv object and locking of the BO. This not only simplifies the handling massively, but also results in much better response time when cleaning up buffers.

drm/ttm: rework bulk move handling v5

2022-03-29T08:55:32+00:00

Instead of providing the bulk move structure for each LRU update set this as property of the BO. This should avoid costly bulk move rebuilds with some games under RADV. v2: some name polishing, add a few more kerneldoc words. v3: add some lockdep v4: fix bugs, handle pin/unpin as well v5: improve kerneldoc Signed-off-by: Christian König Tested-by: Bas Nieuwenhuizen Reviewed-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20220321132601.2161-5-christian.koenig@amd.com

It covers more than just ttm_bo_type_sg usage, like with say dma-buf, since one other user is userptr in amdgpu, and in the future we might have some more. Hence EXTERNAL is likely a more suitable name. v2(Christian): - Rename these to TTM_TT_FLAGS_* - Fix up all the holes in the flag values Suggested-by: Christian König Signed-off-by: Matthew Auld Cc: Thomas Hellström Cc: Christian König Acked-by: Christian König Link: https://patchwork.freedesktop.org/patch/msgid/20210929132629.353541-1-matthew.auld@intel.com Signed-off-by: Christian König
