Powertop by itself doesn't set any tunables on boot
There is a systemd unit that runs powertop with --auto-tune
For stuff like framebuffer compression, the Intel driver only enables
it
on sufficiently new hardware where it's expected bugs are less likely.
Maybe some similar heuristic could be used for setting default tunables,
but I'm not sure what it would be without specific examples.
thermald seems to be something else entirely - it's for thermal
throttling. This might prevent the thermal MCE's that pop up when my
machine overheats, but as far as I can tell is an independent issue.
It does prevent the thermal MCE warnings on one of my laptops; seems
to more aggressively throttle that machine while also maybe ramping up
the fans sooner.
