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

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

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

Patch 1 fixes nva3 bailing due to not finding the right ramcfg Patch 2 is a resend rebased on 3.17.0-rc4 for setting the vblank period Patch 3-5 handle writes to per-partition registers, for which NVA3 does not have special broadcast regs available. Patch 6 removes local structs from NVA3 reclocking in favour of the already existing "ram->base." variables, like in NVE0 As always,

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. Notable changes - Training pattern

Patch 1 and 2 implement wait-for-vblank, required to remove flicker when reclocking memory Patch 3 and 4 allow me to do things between waiting for VBLANK and disabling FB, like pause PFIFO and wait for the engines to idle. This minimises the time PFIFO is paused, thus maximises performance. The rest of the patches speak for themselves. As the actual memory reclocking script is still somewhat prone

I've splitted my big series between the part which actually fixes the engine reclocking bits and the part handling voltage/clock updates on temperature change, so that the more reviewed parts can be merged in faster. This series fixes a lot of Engine reclocking issues found on Fermi, Kepler and all Maxwell generation GPUs. It does _not_ fix memory reclocking on Fermi. It mostly contains of

Sometimes boot scripts leave the "DLL reset" bit on, but it shouldn't be set on every MR write. V2 addresses this by forcing DLL reset off in MR generation
