similar to: RESEND NVA3 clock tree improvements

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

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

Reclocking of NVAA/NVAC is substantially different from NV50+, enough to justify a separate clock implementation. This code is a forward-port of reclocking code that has been sitting in a branch for a while, and has been tested on my NVAC. Traces show no significant reasons why this shouldn't work on NVAA, but testers are always welcome. And since these are IGPs without dedicated RAM to

Following a series of patches that implement memory reclocking for NVA3/5/8 with DDR2, DDR3 and GDDR3 on board. I tested these patches on 6 different graphics cards, but I expect reclocking now to work on many more. Testers can pick up these patches and test it by enabling pstate (nouveau.pstate=1). They should then be able to change clocks by writing to /sys/class/drm/card0/device/pstate. Correct

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

The patches contain some tidy-up work, and refactoring that has arisen as a by-product of my initial work on adding TV support to nv50. Joel Holdsworth (4): drm/nouveau: Removed unneeded include in nvc0_fence.c drm/nouveau: Replaced magic numbers with defines from nouveau_reg drm/nouveau: Replaced copy-pasted nv_wait with nv50_wait_dpms_ctrl helper drm/nouveau: Refactored encoder

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

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.

Hey Alex, Thanks. I have a couple of questions and remarks, but really, those should be treated as discussion points rather than anything else. Besides some inline comments, I was curious whether it is not necessary to pause PFIFO and the engines like done with at least NVA3-NVAF? Or is the transition smooth enough? op 10-07-14 09:34, Alexandre Courbot schreef: > Add support for

There might be some callers of nouveau_clock_astate(), and they are from inetrrupt context. So we must ensure that this function can be atomic in that condition. This patch adds one parameter which is subsequently passed to nouveau_pstate_calc(). Therefore we can choose whether we want to wait for the pstate work's completion or not.

Hey Vince, Ah sorry, I thought my comment on the other patch indicated I was fine with it. I'll merge them now so they don't get lost :) Thanks, Ben. > > Thanks, > Vince > > > On 12/22/2014 05:11 PM, Vince Hsu wrote: >>
