Anyone with a multi CCD Ryzen

[F.Ultra]

Trying to figure out how to automatically detect if a Ryzen CPU have more than one CCD so if any one with such a model which includes all the 1xxxx Ryzens, 26xx and 27xx, 3100, 35xx, 36xx, 37xx, 38xx and 39xx, 59xx and 79xx models.

Hopefully that the needed info should be under /sys/devices/system/cpu/cpuX/topology/ so running say:

for f in /sys/devices/system/cpu/cpu*/topology/* ; do echo $f; cat $f; done

should provide a nice list of stuff to go over and hopefully find something useful to detect on.

Found one such report from the Feral Gamemode github page where a person with a 3700x had uploaded an extract from the topology data and there was nothing in that to indicate that the CPU used 2 CCD:s so it looks like this is currently not possible to detect in any other way than to go by a hardcoded list of known cpu:s...
