Ok, I'm uploading another thermald log that shows it restricting
performance even more than before (probably because I was able to get
the temperature higher), and then NOT improving performance again once
temperatures have gone back down to normal.  thermald was started when
temperatures were cool and performance was at max (I put 'date' in the
log, 8:42:43am).  Then I used a combination of stress-ng and some wine
programs to get a high temperature, which eventually restricted my
performance to minimums (but not quite 0KHz as indicated by pstate-
frequency). Once temperature was back to normal the performance stayed
at low levels and I stopped thermald.  At that point:
