Does GK20A itself have any kind of thermal protection capabilities? Upstream SOCTHERM support is not yet available (though I have a driver in my tree), so we are thinking of disabling CPU DVFS on boards that don't have always-on active cooling for now. Same might be necessary for GPU as well.
There is a small thermal driver ( https://android.googlesource.com/kernel/tegra/+/b445e5296764d18861a6450f6851f25b9ca59dee/drivers/video/tegra/host/gk20a/therm_gk20a.c ) but it doesn't seem to do much. I believe that for Tegra we rely in SOCTHERM instead, but maybe Ken could confirm?
