Hi,
Building on the blob-property submission series[0], this provides a
MODE_ID property that can be used to set the current mode for a CRTC
under atomic modesetting, plus a way for users to create blob
properties so they can specify their own modes.
Using this[1] I've been able to validate the atomic userspace API with
a ported version of Weston[2]. This is currently undergoing review, but
seems pretty OK. Both modesetting for every output together, and
per-output async pageflips with events, works as well as the driver
does.
Also tested with fbcon and X11, on Broadwell.
Cheers,
Daniel
