The todo was to have some drm wrappers here for the boilerplate, but after looking at your version that's not a good idea. So not just making sure crtcs/connectors have a debugfs directory made for them, but more. Wrt adding a new directory: debugfs isnt uapi, but there's usually a massive pile of script relying on them, so it's not nice to shuffle paths around. Plus the lifetimes match anyway (at least if you don't hotplug connectors, which tegra doesn't do). -Daniel -- Daniel Vetter Software Engineer, Intel Corporation http://blog.ffwll.ch _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
