5.17 Kernel & amd-pstate scaling driver support

[RyanSmithOnline]

When using the amd-pstate scaling driver, tuxedo-control-center does not work correctly.

I am unable to set frequencies in the program and so tried to manually set them in /etc/tcc/profiles but when running some profiles my log (journalctl | grep tcc) is spammed with 'CpuWorker: Unexpected value boost => false instead of true'.

I'm using linux-tkg but I imagine this will affect all 5.17 kernels where the new amd-pstate scaling driver is enabled.

Ryzen 5900HX.

Hello,

I think your suspicion is correct, this still needs to be implemented/adjusted to the parameters it provides.

You can check the output of

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver

to see which driver is in use.

amd-pstate

For now I compiled the kernel without amd-pstate so I can continue to use my tuxedo-control-center profiles :)

Since the mainline kernel is out of release candidates state, I'ld like to wish for a look at the actual implementability of the new amd_pstate driver, aswell. So far it seems to be working for me, with tuxedo-control-center, except for a few quirks. On my normal office use, control-center holds my Pulse 14, 4800H at 1,4 Ghz constant at around 40°. Same is happening on the amd_pstate driver as well. Except when I send the laptop to idle. After that the pstate obvously kicks in, cause frequency hovers all over the place and the temperature goes down to 35°, with occasional spikes up to 42° induced by programs running. If I uninstall control-center-bin and tuxedo-keyboard, the same behaviour is to be seen like after what happens after the standby.

All HUD elements in the control-center show the right values and can be tuned, as usual.

fyi
