What about XRandr? Does XRandR support 90 or 270 on your system?
Yup, that works.
meh, my assumption was that if we have rotation on XRandR, we get the
same rotations on DRM. So either my code doesn't work for rotation or
we need to rotate the crtc instead of the plane. Can you try the
supportedTransformations patch and check the debug output which
rotations are supported for the planes?
For the record: while working on the X11 side I noticed that XRandR
supports all rotations as well. Thus I have a system where I can further
investigate.
Cheers
