Following a series of patches to improve nouveaus clock tree parsing. Reclocking these engines (all but memory) is pretty stable on the cards I've tested. Please review and merge when approved. These patches do not solve the problem that core/shader engine doesn't like to be clocked up too far without fb following, with visible corruption as a result. I suspect this problem is unrelated

Resend of patch #7 to fix behaviour when failing to pause parts of the GPU

Re-resend of patch #7 to move the _post and _pre function prototypes to nva3.h

Adds a NvReclock boolean option to allow the user to enable (or disable) reclocking. All chipsets default to off, except NVAA/NVAC, which are reportedly complete.

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

This series addresses various issues inside the reclocking code: 1. after resume the set clocks are reset 2. reclocking not possible while GPU is suspended 3. nouveau always does full reclocks even if only a change of the voltage is required Some of the patches were part of the bigger reclocking series I sent months ago, some things have changed though. This is also preparation work of

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

Hello everyone, I would need testers to check that this patch doesn't break working NVAA/NVAC configurations. It fixes an issue where some NVAC would hang on boot; if similar issues exist on NVAA, it may fix them too. You will find the patch below in two different versions: one will apply on Ben Skeggs' repository, the other one will apply on a regular Linux tree. Thanks in advance,
