Errors when changing to balance on a Ryzen system

[alosarjos]

Hi there!

I'm just giving a try to tuned instead of the regular PPD but I'm seeing some errors on the logs, not sure if an issue on my side or the program.

When changing to balance and running a tuneadm-verify I'm getting some errors. From the logs:

Boost file seems to exists:

Hi, are you able to change the content of the boost file manually?

[alosarjos]

Looks like I can't, maybe it's something that has yet to be enabled? Looking for some info, I found:

https://lore.kernel.org/linux-kernel/9725dfcbb8848d68ce5c8c099cd3c6805bebf20b.1718988436.git.perry.yuan@amd.com/T/

Which are some "recent" kernel patches

I dont have the ' /sys/devices/system/cpu/amd_pstate/cpb_boost' so maybe I cant change the boost yet?
