Adds reclocking for NVA0, and a whole lot of work for other cards. Had these patches collecting dust for a little, but tested them with both my NVA0, and Martin's a while back. Success not guaranteed, but should be quite a leap forward. Happy reviewing and testing. Cheers, Roy

In bulletpoints: - Add some support for G94 and G96 reclocking. Has been tested on literally two cards, which is hardly adequate as "full coverage". On the other hand, the changes were small enough to make me confident this might work for others as well. - Fix NV50 wait for VBLANK when no monitor is plugged in. - Voltage related inprovements for GT21x. - Slightly improve Keplers

No, no, these will not implement Fermi reclocking. This set of patches contains some of the preparatory work that I deem stable enough to move upstream. Notable changes - Training pattern upload routines from GK104+ now shared with GT215+ - Timing calculation for Fermi - GDDR5 MR calculation from VBIOS timing table v1.0. Also useful for that pesky GT 240. - A routine to translate a VBIOS init

Two patches went missing as a result of PEBCAK. No v2 marks as nothing changed really. Just resending for easier enforcement of patch order in other people's trees. Sorry for the noise. Original message: No, no, these will not implement Fermi reclocking. This set of patches contains some of the preparatory work that I deem stable enough to move upstream.

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
