Thanks to my 256g FW flash card, I ran this experiment on the latest version of Fedora Workstation. I followed the instructions at GitHub - FlyGoat/RyzenAdj: Adjust power management settings for Ryzen APUs to:
- build & load
ryzen_smu - install new key using
mbok - build & install
ryzenadj
The module seems loaded:
$ lsmod | grep ryzen_smu
ryzen_smu 45056 0
But, there are errors in the log:
$ sudo dmesg | grep ryzen_smu
...
ryzen_smu: SMU v11.93.4.0
ryzen_smu: Unknown PM table version: 0x005D0009
ryzen_smu: Failed to probe the PM table -- disabling feature (249)
...
AI suggests that the Ryzen AI 9 HX 370 is using a newer SMU firmware (v11.93.4.0) with a Power Management (PM) table version 0x005D0009 that the current ryzen_smu module doesn’t recognize.
So, this test didn’t directly yield what we were looking for. But, I did note that the high-temp issue was not present on the latest version of Fedora which is sporting kernel 6.15.6-200.fc42.x86_64 vs. the 6.14.11-200.fc41.x86_64 on my Bluefin-dx GTS.
So, it seems that kernel 6.15 has the high idle temp issue more or less addressed.
