Hello, Attached a small patch that correctly identifies the DLLoff bit for >=GF100. Marked RFC because I haven't seen any GDDR5 samples that *enable* the DLL. I'd like to verify whether the DLL should be reset when enabled. Could increase likelihood of succesfull reclock. Ben: could you do some experiments with this bit to see if GDDR5 needs some DLL reset logic? Thanks, and happy

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

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

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

A quick look over the memory reclocking part inside the maxwell mmiotraces kind of reminded me of the kepler memory reclocking, it looks for most parts the same. I didn't do a deep inspection so treat this with great care, but it seems to work at least on those maxwell gpus this was tested on. It depends on the PMU fixes for the fuc5 though, otherwise the PMU might not work as expected and

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
