Description
My AMD Ryzen 5700u (which seems untested) is not recognized as AMD Zen. It has type 0x60f80, and apparently is part of the Lucienne line.
Alongside this, zen_workaround.py fails to run, with the following log:
[moony@fedora obj]$ sudo ../rr/scripts/zen_workaround.py
Traceback (most recent call last):
File "/home/moony/Projects/obj/../rr/scripts/zen_workaround.py", line 46, in <module>
os.write(msr, struct.pack('<q', val))
PermissionError: [Errno 1] Operation not permitted

Research direction
Start with scripts/zen_workaround.py and the code that identifies AMD Zen CPUs; use the reported Ryzen 5700U type 0x60f80 and the logged PermissionError as the reproduction details. Done means the processor is recognized as AMD Zen and the workaround's behavior for this system is addressed, with relevant tests or reproduction steps documented.
