drm/amdgpu: Prepare for hmm_range_register API change (v2)

2019-07-08T18:55:00Z

An upcoming change in the hmm_range_register API requires passing in a pointer to an hmm_mirror instead of mm_struct. To access the hmm_mirror we need pass bo instead of ttm to amdgpu_ttm_tt_get_user_pages because mirror is part of amdgpu_mn structure, which is accessible from bo. v2: fix building without CONFIG_HMM_MIRROR (Arnd) Signed-off-by: Philip Yang Signed-off-by: Felix Kuehling Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: fix HMM config dependency issue

2019-05-24T17:21:02Z

Only select HMM_MIRROR will get kernel config dependency warnings if CONFIG_HMM is missing in the config. Add depends on HMM will solve the issue. Add conditional compilation to fix compilation errors if HMM_MIRROR is not enabled as HMM config is not enabled. Remove unused function amdgpu_ttm_tt_mark_user_pages.

drm/amdgpu: replace get_user_pages with HMM mirror helpers

2019-05-24T17:21:02Z

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().

drm/ttm: initialize globals during device init (v2)

drm/ttm: use a static ttm_mem_global instance

2018-11-05T19:21:18Z

As the name says we only need one global instance of ttm_mem_global. Drop all the driver initialization and just use a single exported instance which is initialized during BO global initialization. Signed-off-by: Christian König Reviewed-by: Junwei Zhang Signed-off-by: Alex Deucher

drm/amdgpu: Free VGA stolen memory as soon as possible.

2018-05-15T18:43:16Z

Reserved VRAM is used to avoid overriding pre OS FB. Once our display stack takes over we don't need the reserved VRAM anymore. v2: Remove comment, we know actually why we need to reserve the stolen VRAM. Fix return type for amdgpu_ttm_late_init. v3: Return 0 in amdgpu_bo_late_init, rebase on changes to previous patch v4: rebase v5: For GMC9 reserve always just 9M and keep the stolem memory around until GART table curruption on S3 resume is resolved.

drm/amdgpu: use separate status for buffer funcs availability v2

2018-03-05T20:37:24Z

The ring status can change during GPU reset, but we still need to be able to schedule TTM buffer moves in the meantime. Otherwise we can ran into problems because of aborted move/fill operations during GPU resets. v2: still check if ring is available during direct submit.
