Hi Alex, Thanks for your information. I updated the patch using the amdgpu_dpm_get_sclk/mclk APIs which make the patch much simpler.

That's mostly just leftover from radeon. A better solution would be use the existing amdgpu_dpm_get_sclk and amdgpu_dpm_get_mclk macros. Maybe something like the attached patch? Unless there is a specific need for the max clocks on AC. I think in most cases the results will be the same.

The attached patch tries to fix it. Please help to review it. Any comment is welcomed. Regards, Evan -------------- next part -------------- An HTML attachment was scrubbed...
