Did you enable AMDGPU DC by changing kernel boot parameters?

I tried to capture some dmesg log, but booting with suggested kernel line
amdgpu.dc_log=1 but no output was produced at flickering. Than I realized that
I have to enable amdgpu.dc in order to use it's logging :) and the issue
disappeared. So far after a hour I don't see any flickering anymore.</pre>
