Keeping it in VRAM wastes CPU time, because cursor_set ioctl reads handed BO back to RAM, just to write it to actual cursor BO. Here (nv92/core i7), this patch decreases overall cpu usage of drmmode_load_cursor_argb from 4.6ms to ~90us and lets nv50_crtc_cursor_set disappear from perf traces. --- I considered accelerating kernel-side copying with GPU, but it turns out that: - it's slower (120-150us), with frequent bursts (up to 5ms) - not applicable to <nv50 hw, which needs to transform cursor data Putting cursor BO in GART does not conflict with acce...

A couple of new warnings and build errors appeared through the DRM tree in linux-next after the merge window opened. The first patch here is for scripts/headers_check.pl, but as the bug is only present in drm-next at the moment, it would be good to add all five patches to that tree before they make it into mainline. It's likely that some of these have already been fixed since this
