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
/etc/initramfs-tools/modules
and include amd_pstate
at the end of the text file/etc/default/grub
and modify this line GRUB_CMDLINE_LINUX="initcall_blacklist=acpi_cpufreq_init"
sudo update-grub
then sudo update-initramfs -u
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.
