--- Comment #27 from Mario Limonciello (AMD) (mario.limonciello@amd.com) ---
So I think there are actually two issues in this bug.
* The first one was the one that Artem reported which looks like a problem with
the EC communicating some limits to the APU. This is Artem's issue.
* The second one is that there was a bug in amd-pstate that could cause CPPC
requests to have the wrong values. This is (nearly) everyone else's issue in
this bug.
The second issue is fixed by
https://github.com/torvalds/linux/commit/22fb4f041999f5f16ecbda15a2859b4ef4cbf47e
For the first issue, Artem can you update to 6.8-rc7, make sure you've added
the TEE firmware for the amd-pmf driver from linux-firmware and see if you can
still reproduce it?
