Credit goes to Claude btw. It pulled the kernel firmware binary apart, found the location of the perfomance toggle and then wrote a oneliner to read it at runtime:
```
root@pve:~# python3 -c 'import mmap,os;m=mmap.mmap(os.open("/dev/mem",os.O_RDONLY),4096,mmap.MAP_SHARED,mmap.PROT_READ,offset=0xFEC40000);print({0:"Balanced 85W",1:"Performance 120W",2:"Quiet 55W"}.get(m[0x431],m[0x431]))'
Balanced 85W
```

It's actually well covered on the excellent Strix Halo wiki: https://strixhalo.wiki/Guides/Power_Modes_and_Performance/
