Hello,
I am looking to see if I can minimize the need to switch between Windows and Fedora by gaming on Fedora where possible.
I have an AMD RX480 and I’m looking into undervolting it on Fedora as it throttles itself when trying to run at full power.
I have found several guides stating I need to add:
amdgpu.ppfeaturemask=0xfffd7fff or amdgpu.ppfeaturemask=0xffffffff to the kernel command line to unlock the settings files needed to achieve this. However when setting this it causes my screen to flicker.
I am currently using kernel version 5.5.7 and mesa version 19.2.8 but also tried it yesterday prior to the the kernel update and got the same issue.
I am wondering if anyone has any experience and knows if this is an issue with my card or with the kernel drivers?
Edit: Rebasing to F32 branched version doesn’t resolve it if it’s related to drivers. Not sure how officially supported it is to be raising a bug report though.
