Subject: [PATCH 00/13] Atomic Properties
Date: Tue, 16 Dec 2014 18:05:28 -0500	[thread overview]
Message-ID: <1418771141-16954-1-git-send-email-robdclark@gmail.com> (raw)

Now that we have core atomic helpers, let's expose that to userspace!
The first step here is to, for drivers supporting atomic, expose all
the core plane/CRTC/connector state as properties.  Once this is in
place, all that remains is the atomic ioctl to allow userspace to
atomically set a bunch of properties on a bunch of objects (RFC patch
at the end).

All of the core properties have their set/get/check's handled  by the
drm_atomic core, so drivers needn't be bothered about that.

NOTE: that there is one notable omission here.  The 'MODE' property
on the CRTC.  Without this, you can do atomic pageflip but not yet
atomic modeset.  I am debating between three paths for handling MODE:

 1) Add back blob property support to atomic ioctl
 2) Add ioctls to create/destroy blob properties, and then simply
    pass blob property id to atomic ioctl.
 3) Stick our head in the sands and expose mode as a bunch of descrete
    properties.

Of these, at the moment I prefer #2, since it is more consistent with
how userspace currently reads blob properties, and it avoids making the
atomic ioctl function even more gnarly.
