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

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
