Thanks.

It's a bit mask; see include/drm/drmP.h in the kernel tree for the bit
definitions. 0x10 is atomic modeset debugging; it's pretty verbose, I
personally prefer to not include that unless I think it's needed. Makes it
easier to read the logs without it, but others may have different
preferences...
