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.

[PATCH 0/3] drm/gk20a: support for reclocking

2014-07-10 Thread Alexandre Courbot
This series adds support for reclocking on GK20A. The first two patches touch the clock subsystem to allow GK20A to operate, by making the presence of the thermal and voltage devices optional, and allowing pstates to be provided directly instead of being probed using the BIOS (which Tegra does not
