The counters on M3UPI Link 0 and Link 3 don't count. Writing 0 to
these counters may causes system crash on some machines.

The PCI BDF addresses of M3UPI in current code are incorrect.
The correct addresses should be
D18:F1 0x204D
D18:F2 0x204E
D18:F5 0x204D

Should this have a Fixes: tag?


Yes, sorry for missing it.
Here it is.
Fixes: cd34cd97b7b4 ("perf/x86/intel/uncore: Add Skylake server uncore support")

Thanks,
Kan
