Yeah, it didn’t really occur to me either at first. I had the “people with no pcid are going to be in trouble” understanding but figured it’s not a big deal. Then, when testing code and seeing zero difference in speed, I started sanity checking. After looking around at code to see why pti was doing nothing, it turned out KAISER was turning pti off because the KVM guest I was on had no pcid.
