drm/amdgpu: Refactor amdgpu_vram_mgr_bo_invisible_size helper

2018-07-08T13:32:19Z

commit 5e9244ff585239630f15f8ad8e676bc91a94ca9e upstream. Preparation for the following fix, no functional change intended. Cc: stable@vger.kernel.org Signed-off-by: Michel Dänzer Reviewed-by: Christian König Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

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

2018-03-05T20:37:12Z

Instead of setting the active VRAM size directly provide a the info if we can use the buffer functions or not. Signed-off-by: Christian König Acked-by: Chunming zhou Signed-off-by: Alex Deucher

drm/amdgpu: move some functions into amdgpu_ttm.h

2018-03-05T20:37:05Z

Those belong to the TTM handling. Signed-off-by: Christian König Reviewed-by: Chunming Zhou Signed-off-by: Alex Deucher

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

drm/amdgpu: revert "Add support for filling a buffer with 64 bit value"

2018-02-19T19:18:55Z

This reverts commit 7bdc53f925af085ffa0580f10489f82b36cc2f1c and commit 330df03b3abf944f8f5180f2abc61367749984c0. Neither are needed any more. Signed-off-by: Christian König Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm: move amd_gpu_scheduler into common location

2017-12-07T16:51:56Z

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.

drm/amdgpu: rename amdgpu_ttm_bind to amdgpu_ttm_alloc_gart

2017-12-04T21:41:43Z

We actually don't bind here, but rather allocate GART space if necessary. Signed-off-by: Christian König Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: move GART recovery into GTT manager v2

2017-12-04T21:41:33Z

The GTT manager handles the GART address space anyway, so it is completely pointless to keep the same information around twice. v2: rebased Signed-off-by: Christian König Reviewed-by: Chunming Zhou Signed-off-by: Alex Deucher

drm/amdgpu: nuke amdgpu_ttm_is_bound() v2

2017-12-04T21:41:32Z

Rename amdgpu_gtt_mgr_is_allocated() to amdgpu_gtt_mgr_has_gart_addr() and use that instead. v2: rename the function as well. Signed-off-by: Christian König Reviewed-by: Chunming Zhou Signed-off-by: Alex Deucher
