Hi Ben, Pre-nv40 cards don't have domains defined, which the nouveau_clock_init code assumes exists. The following (white-space-damaged, sorry) patch fixes boot for me, haven't really tested the pre-nv40 cards in my system much further. I assume there's some proper fix here. -ilia diff --git a/drivers/gpu/drm/nouveau/core/subdev/clock/base.c b/drivers/gpu/drm/nouve...

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 have). The last patch adds the GK20A clock device. Arguably the clock can be seen as a stripped-down

Second version of the gk20a clock patches. I have tried to keep the therm and volt devices mandatory in the clock driver, but unfortunately they are too tied to bios to allow this, at least for the moment. Consequently this version is mostly a port of the first version to Ben's tree. Ben, please let me know what I have done wrong in terms of integration to your tree, as the main purpose of
