drm/amdgpu: fix size calculation with stolen vga memory

2020-12-09T15:06:40Z

If we need to keep the stolen vga memory, make sure it is at least as big as the legacy vga size. Acked-by: Christian König Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org

drm/amdgpu: add an auto setting to the noretry parameter

2020-09-25T20:55:21Z

This allows us to set different defaults on a per asic basis. This way we can enable noretry on dGPUs where it can increase performance in certain cases and disable it on chips where it can be problematic. For now the default is 0 for all asics, but we may want to try and enable it again for newer dGPUs. Reviewed-by: Christian König Reviewed-by: Luben Tuikov Signed-off-by: Alex Deucher

drm/amdgpu: store noretry parameter per driver instance

2020-09-25T20:55:16Z

This will allow us to have different defaults per asic in a future patch. Reviewed-by: Christian König Reviewed-by: Luben Tuikov Signed-off-by: Alex Deucher

drm/amdgpu: move stolen memory from gmc to mman

It's more related to memory management than memory controller. Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu/gmc: disable keep_stolen_vga_memory on arcturus

2020-08-04T21:29:29Z

I suspect the only reason this was set was to avoid touching the display related registers on arcturus. Someone should double check this on arcturus with S3. Reviewed-by: Christian König Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu/gmc: add new helper to get the FB size used by pre-OS console

drm/amdgpu: implement TMZ accessor (v3)

2020-04-28T20:20:29Z

Implement an accessor of adev->tmz.enabled. Let not code around access it as "if (adev->tmz.enabled)" as the organization may change. Instead... Recruit "bool amdgpu_is_tmz(adev)" to return exactly this Boolean value. That is, this function is now an accessor of an already initialized and set adev and adev->tmz. Add "void amdgpu_gmc_tmz_set(adev)" to check and set adev->gmc.tmz_enabled at initialization time. After which one uses "bool amdgpu_is_tmz(adev)" to query whether adev supports TMZ. Also, remove circular header file include. v2: Remove amdgpu_tmz.[ch] as requested. v3: Move TMZ into GMC. Signed-off-by: Luben Tuikov Acked-by: Christian König Signed-off-by: Alex Deucher
