Enable xfer only when we need it to save power
drm/nv50/ctxprog: enable xfer only when we need it to save power
This patch adds instructions to ctxprog and by doing, impact context-switching
performance.
My testcase showed a 1% performance cost using glxgears that is a
context-switch bound application.
Please test and report bugs/performance/power/other.
