Sorry, not following. What sort of "examples"? Are there similar examples
in xe_drm.h, could you please point them out so we know what to add. Or you
mean examples outside xe_drm.h, e.g. in Documentation/ e.g.?

The IGT series was also posted along with the kernel series here:

	https://patchwork.freedesktop.org/series/121082/

That has plenty of examples but probably that's not what you mean?

Thanks.
