--- Comment #4 from David Mak (david.18.19.21@gmail.com) --- Created attachment 294239 --> https://bugzilla.kernel.org/attachment.cgi?id=294239&action=edit dmesg outputs for 5.9.14 and 5.10.1.
I can reproduce the issue on the RX 6800 (Navi 21 XL).
I use Radeontop to inspect the memory/GPU clock of my GPU.
When using Linux 5.9.14: - In both KDE Plasma and tty2, Memory Clock hovers at around 100MHz. - GPU Power reported by lm_sensors is around 5-7W.
When using Linux 5.10.1: - In tty2, Memory Clock hovers at around 100MHz and GPU Power reported by lm_sensors is around 5-7W. - In KDE Plasma, Memory Clock is usually around 1GHz (100%), although it can be down to ~470MHz, and GPU Power reported by lm_sensors is around 30W. - Disconnecting one of my two monitors does not change the memory clock.
I am trying to bisect the commit, but many revisions seem to give a blank screen or the amdgpu module is not loaded. (I suspect I am not building the kernel properly)
Tested linux-firmware versions: 20201120.bc9cd0b, 20201218.646f159
