[Intel-gfx] [PATCH] drm/mm: Convert to drm_printer
Daniel Vetter
daniel.vetter at ffwll.ch
Thu Dec 29 11:09:24 UTC 2016
Including all drivers. I thought about keeping small compat functions
to avoid having to change all drivers. But I really like the
drm_printer idea, so figured spreading it more widely is a good thing.
v2: Review from Chris:
- Natural argument order and better name for drm_mm_print.
- show_mm() macro in the selftest.
