cpupower not working with 15.2 on my laptop

cpupower used to work under leap 15.1 and now it doesn’t.

I did not upgrade from 15.1 to 15.2, I backed up my data and wiped the disk to install 15.2 as a fresh install. The cpu is an old AMD-A10

Now I get:


$ cpupower frequency-info
analyzing CPU 0:

here’s my inxi

To me it looks like it’s missing some driver, but I don’t know what.

I’d like to enable the performance governor

Thanks

Hi
I use to have one of those Dells, do you see acpi errors (or something in the grub command line options) as acpi-cpufreq module should be loaded?

If no acpi options, try adding the following to kernel command line options via YaST bootloader;


acpi_enforce_resources=lax

It doesn’t look like there’s any error:


Jul 08 18:13:15 localhost kernel: ACPI: LAPIC_NMI (acpi_id[0xff] high edge lint[0x1])

Does this mean that it’s already at “full speed”?

I’m just starting a zoom meeting. I’ll try the grub parameter tomorrow

Thanks for the insight
