drm/amdgpu: just disallow reading untouched registers

2017-03-30T18:44:00+00:00

Not sure what the original intention was here, but returning a random piece of kernel memory to userspace because we didn't set the value at all is clearly not a good idea. This patch disallows reading the register and returns a proper error code instead. Signed-off-by: Christian König Acked-by: Alex Deucher Acked-by: Tom St Denis Signed-off-by: Alex Deucher

drm/amdgpu: use new flag to handle different firmware loading method

2017-03-30T03:54:33+00:00

This patch introduces a new flag named "amdgpu_firmware_load_type" to handle different firmware loading method. Since Vega10, there are three ways to load firmware. It would be better to use a flag and a fw_load_type kernel parameter to configure it. Acked-by: Christian König Signed-off-by: Huang Rui Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu:cg & pg shouldn't active on VF device
