A question about the USE of Highest Way in l3_cat

[mdcornu]

Apologies for the delayed response.
If you run pqos -Vs you will see a line similar to this:
INFO: L3 CAT details: CDP support=1, CDP on=0, #COS=16, #ways=11, ways contention bit-mask 0x600

The "ways contention bit-mask" represents cache ways that are shared by other entities (e.g IO device such as PCIe, CXL, etc... ).
When using CAT, those cache ways cannot be individually selected.
