AMD p-state in kernel 5.17 oem?

Hi,

As far as I can see, Jammy with OEM 5.17 kernel is still using cpufreq (CPU Ryzen 7 5850u).
Is it planned to switch to new AMD p-state ?
Is there an option I can add to grub to use p-state ?

Ok.

HOW TO ENABLE AMD-PSTATE FOR UBUNTU JAMMY WITH KERNEL 5.17 OEM

  • edit /etc/initramfs-tools/modules and include amd_pstate at the end of the text file
  • edit /etc/default/grub and modify this line GRUB_CMDLINE_LINUX="initcall_blacklist=acpi_cpufreq_init"
  • in a terminal, execute sudo update-grub then sudo update-initramfs -u
  • reboot
  • check that less /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver returns amd-pstate (you can also check this with sudo tlp-stat -p )

Latest Jammy 5.17*.1004-oem kernel does make p-state by default. No more tweaks needed.
