Keith Packard is pushing back the closing of the X.Org Server 1.13 merge window to next week in order to allow the new RandR patches to land, which is needed for the GPU hot-plugging support.
The patches that Keith Packard is talking about is mainly the provider object support
that will become RandR 1.5. This update to the Resize and Rotate extension for X.Org is needed for USB GPU hot-plugging and GPU offloading
. David Airlie of Red Hat has been working quite aggressively on these X.Org feature improvements
. Below is Packard's message in full.
I'm a softy and you all know it...
Dave Airlie is busy cleaning up the RandR changes for a bit of output device hotplug fun; the basic X server changes are mostly reviewed, he's just rewriting the protocol at the last minute after review of that. It'd be nice to get that into 1.13 as it's a cool feature, and required to support GPU hotplugging.
Daniel Stone promises to have some simple cleanups ready in the next couple of days as well.
So, we'll leave the window open for a couple of days and see if these changes can't get merged in as well.
Current plan is to wait and see if these changes are going to be ready in the next couple of days and then get them merged before declaring a feature freeze.
David's already landed DDX driver API changes
for this forthcoming xorg-server 1.13 release. X.Org Server 1.13 should be released in September.
