seems right though we should probably decrease the logging, its a lot
to spam dmesg with everytime.
for nouveau I made a log level for dynamic pm suspend/resume that
didn't log stuff, I think it should
probably be silent in dmesg and transparent to users.
Maybe with a file in sysfs or somewhere to say what the actual GPU state is,
