It's been a while since I've been through the SMU code so I don't know
all the places that restore_uesr_profile is used, but, just to confirm,
these would still go back to default (boot) values on a GPU reset, yes?
I ask because when pushing OD settings too far, GPU resets are often
encountered, and you might be able to create a state where it would
continually reset if your OD settings are remembered even through a full
Very nice feature other than that, though, as I actually keep
`radeontop` open in a tmux session to prevent my secondary card from
resetting my OD settings, so this will be nice.
