Another question: Sebastian Reichel showed a rotated console on omap4 in his fosdem presentation, so can we do it the same way?
Interesting.
Well, we can do it the same way if we know the way he is doing it. Did he share any details? Or a pointer to the code doing this?
I just specified "fbcon=rotate:1" on the command line. This will result in the kernel console being rendered rotated on all displays. This directly renders the console rotated, so it's completly unrelated to omapdrm. X is not affected and will start without rotation being applied. For Droid 4 / OMAP4 xrandr based rotation does work without any patches, though (except for [0]).
I plan to add support for the new "panel orientation" property [1] to omapdrm once support for manually updated displays landed. This should help to get rotation applied correctly out of the box without any hacks required in the omapdrm code.
