So I just tested a few shutdown vs. reboot cycles, and if I reboot, I only get three counters. If I shutdown, then restart, I get 4 counters (including the "psys domain" one). I tried it on a few kernels, including the oldest one that comes with my distro (5.3.0-40-generic) where all the RAPL stuff is made as modules. So, maybe we're not "clearing" (wild guess here) the "psys" RAPL on a reboot, something that would happen on a cold boot? (I'm afraid to say the "B-word", as that would mean it's a Dell issue so I won't hold my breath waiting for a fix). -Kenny -- Kenneth R.
