drm/ttm: return -EBUSY on pipelining with no_gpu_wait (v2)

2019-12-31T15:43:00+00:00

[ Upstream commit 3084cf46cf8110826a42de8c8ef30e8fa48974c2 ] Setting the no_gpu_wait flag means that the allocate BO must be available immediately and we can't wait for any GPU operation to finish. v2: squash in mem leak fix, rebase Signed-off-by: Christian König Acked-by: Felix Kuehling Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin

drm/ttm: fix handling in ttm_bo_add_mem_to_lru

2019-10-14T11:21:15+00:00

We should not add the BO to the swap LRU when the new mem is fixed and the TTM object about to be destroyed. Signed-off-by: Christian König Reviewed-by: Kevin Wang Link: https://patchwork.freedesktop.org/patch/335246/

drm/ttm: Restore ttm prefaulting

2019-10-14T10:49:24+00:00

Commit 4daa4fba3a38 ("gpu: drm: ttm: Adding new return type vm_fault_t") broke TTM prefaulting. Since vmf_insert_mixed() typically always returns VM_FAULT_NOPAGE, prefaulting stops after the second PTE. Restore (almost) the original behaviour. Unfortunately we can no longer with the new vm_fault_t return type determine whether a prefaulting PTE insertion hit an already populated PTE, and terminate the insertion loop. Instead we continue with the pre-determined number of prefaults.
