Revert "drm/amdgpu: replace get_user_pages with HMM mirror helpers"

This reverts commit 915d3eecfa23693bac9e54cdacf84fb4efdcc5c4. This depends on an HMM fix which is not upstream yet. Signed-off-by: Alex Deucher

drm/amdgpu: Only clear dumb buffers if ring is enabled

2019-03-19T20:36:57+00:00

The buffers should be cleared when possible but we also don't want buffer creation to fail in the rare case where the ring isn't ready during the call. This could happen during some suspend/resume sequences. Cc: Christian König Signed-off-by: Nicholas Kazlauskas Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: Clear VRAM for DRM dumb_create buffers

2019-03-19T20:36:57+00:00

The dumb_create API isn't intended for high performance rendering and it's more useful for userspace (ie. IGT) to have them precleared. The bonus here is that we also won't needlessly leak whatever was previously in VRAM, but it also probably wasn't sensitive if it was going through this API.

drm/amdgpu: replace get_user_pages with HMM mirror helpers

2019-03-19T20:03:45+00:00

Use HMM helper function hmm_vma_fault() to get physical pages backing userptr and start CPU page table update track of those pages. Then use hmm_vma_range_done() to check if those pages are updated before amdgpu_cs_submit for gfx or before user queues are resumed for kfd. If userptr pages are updated, for gfx, amdgpu_cs_ioctl will restart from scratch, for kfd, restore worker is rescheduled to retry. HMM simplify the CPU page table concurrent update check, so remove guptasklock, mmu_invalidations, last_set_pages fields from amdgpu_ttm_tt struct. HMM does not pin the page (increase page ref count), so remove related operations like release_pages(), put_page(), mark_page_dirty().
