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

2018-11-05T19:21:21Z

Make sure that the global BO state is always correctly initialized. This allows removing all the device code to initialize it. v2: fix up vbox (Alex) Signed-off-by: Christian König Reviewed-by: Junwei Zhang Signed-off-by: Alex Deucher

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: add amdgpu_gmc_get_pde_for_bo helper v2

drm/amdgpu: Keep track of amount of pinned CPU visible VRAM

2018-07-13T19:46:11Z

Instead of CPU invisible VRAM. Preparation for the following, no functional change intended. v2: * Also change amdgpu_vram_mgr_bo_invisible_size to amdgpu_vram_mgr_bo_visible_size, allowing further simplification (Christian König) Cc: stable@vger.kernel.org Reviewed-by: Christian König Signed-off-by: Michel Dänzer 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.

drm/amdgpu: change amdgpu_ttm_set_active_vram_size

drm/amdgpu: Map all visible VRAM at startup

2018-02-28T20:38:46Z

When using CPU to update page table, we need to kmap all the PDs/PTs after they are allocated and that requires a TLB shot down on each CPU, which is quite heavy. Instead, we map the whole visible VRAM to a kernel address at once. Pages can be obtained from the offset. v2: move the mapping base from gmc to amdgpu_mman structure, and the implementation in amdgpu_ttm_* functions Signed-off-by: Amber Lin Reviewed-by: Christian König Signed-off-by: Alex Deucher
