2017-12-04drm/amdgpu: Avoid accessing job->entity after the job is scheduled.Andrey Grodzovsky
Bug: amdgpu_job_free_cb was accessing s_job->s_entity when the allocated amdgpu_ctx (and the entity inside it) were already deallocated from amdgpu_cs_parser_fini. Fix: Save job's priority on it's creation instead of accessing it from s_entity later on.

2017-11-15mm: remove cold parameter for release_pagesMel Gorman
All callers of release_pages claim the pages being released are cache hot. As no one cares about the hotness of pages being released to the allocator, just ditch the parameter. No performance impact is expected as the overhead is marginal. The parameter is removed simply because it is a bit stupid to have a useless parameter copied everywhere.

For VM emulation for old UVD/VCE we need to validate the BO with linear VRAM flag set first and then eventually bind it to GART.

2017-07-14drm/amdgpu: Throttle visible VRAM moves separatelyJohn Brooks
The BO move throttling code is designed to allow VRAM to fill quickly if it is relatively empty. However, this does not take into account situations where the visible VRAM is smaller than total VRAM, and total VRAM may not be close to full but the visible VRAM segment is under pressure. In such situations, visible VRAM would experience unrestricted swapping and performance would drop. Add a separate counter specifically for moves involving visible VRAM, and check it before moving BOs there. v2: Only perform calculations for separate counter if visible VRAM is smaller than total VRAM. (Michel Dänzer) v3: [Michel Dänzer] * Use BO's location rather than the AMDGPU_GEM_CREATE_CPU_ACCESS_REQUIRED flag to determine whether to account a move for visible VRAM in most cases. * Use a single if (adev->mc.visible_vram_size < adev->mc.real_vram_size) { block in amdgpu_cs_get_threshold_for_moves.
