[ Upstream commit 7eded018bfeccb365963bb51be731a9f99aeea59 ] We need to move the check under the non-headless case, otherwise we always reserve the VGA save size.

drm/amdgpu: fix size calculation with stolen vga memory

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

2020-09-25T20:55:21+00:00

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

2020-09-25T20:55:16+00:00

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/gmc: disable keep_stolen_vga_memory on arcturus

2020-08-04T21:29:29+00:00

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
