Re: [PATCH] iommu/amd: flush IOTLB for specific domains only

2017-06-03 Thread Jan Ziak 
Hi

I am getting "AMD-Vi: Completion-Wait loop timed out" error
approximately once per several days with R9 390.

Is there a reason why this patch isn't in the mainstream linux-git yet?

[PATCH] drm/amdgpu: correct clock info for SRIOV

2017-06-03 Thread Xiangliang Yu 
Currently, get clock info from default clk of pm if dpm is disable.
Buf SRIOV doesn't support dpm and pm, can't get anything from pm.
Only get clock info only from default clk of amdgpu for SRIOV.

And driver get pm default clk also from amdgpu default clk and never
be changed by others. So use amdgpu default clk value for SRIOV
and non-dpm cases.
