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

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.
