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

2018-07-13T19:46:11+00:00

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.

2018-05-15T18:43:16+00:00

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

2018-03-05T20:37:24+00:00

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: Map all visible VRAM at startup

2018-02-28T20:38:46+00:00

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

drm: move amd_gpu_scheduler into common location

2017-12-07T16:51:56+00:00

This moves and renames the AMDGPU scheduler to a common location in DRM in order to facilitate re-use by other drivers. This is mostly a straight forward rename with no code changes. One notable exception is the function to_drm_sched_fence(), which is no longer a inline header function to avoid the need to export the drm_sched_fence_ops_scheduled and drm_sched_fence_ops_finished structures.
