AMD EPYC 7351P not working

[ocerman]

There has been some reports before, that a restart is needed for some people. This was probably that case.

I am happy that it works. Even though I can see that some 0 values are being reported, which is propably not correct.

best regards, and thanks for this awesome module!

Hm, i just reloaded the kernel module - and that fixed it somehow. No restart needed.

I thought, that those are the disabled dies on the EPYC Chip - but by the amount of L3, I guess all dies are active. Weird.
