I'm afraid that my RockChip-foo is extremely limited. Perhaps the actual user of these should be mentioned ? xf86-video-rockhip (is there one ?) or any other effort/project that lacks some (all?) of the criticism listed. (Sort of) the bottom line - either reuse the existing interfaces or provide an approved, full blown userspace (libdrm demos/programs do not count) that uses the new interfaces. I haven't made these rules, just a fool^Wguy that repeats them so that people don't abuse them much. If in doubt check with Dave and Daniel V - they had enough repeating these. -Emil -- To unsubscribe from this list: send the line "unsubscribe devicetree" i= n the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
