Not sure if possible with drm (perhaps only with certain devices). Would be possible with OpenGL though at least.

Looks like it's more involved than that. https://ereleaseblog.wordpress.com/2015/05/15/fun-with-drm-and-randr/

Still no clue what hardware planes are. Need to figure it out next fortnight I guess. :)

Also, is this related? https://github.com/Cloudef/wlc/issues/64

No, buffer transformations are for clients. (They may request their buffer to be shown rotated for example, where compositor needs to handle input etc accordingly)

Hi. Could the transform parameter of wl_output be what we want?

This describes the transform that a compositor will apply to a surface to compensate for the rotation or mirroring of an output device.

That's only for communicating the current rotation to client.

I haven't looked at the code of either this or Weston to know how compatible they are, but that does handle my rotated monitor correctly. If nothing else, that might point at one way to handle it.

This thread should give an idea how tricky this may prove to be:

Looks like that BZ is marked fixed -- will WLC be able to support this feature in the future, then?
