Daniel Vetter of Intel's Open-Source Technology Center sent in the first batch of drm-intel-next changes for landing into drm-next, David Airlie's DRM tree as the subsystem maintainer for the work that will land in Linux 3.16. The changes already queued up for this next kernel cycle contain a lot of work on an Intel Gen7 command parser, continued Valley View / Bay Trail fixes, continued work on Intel Broadwell support, run-time power management support for Broadwell and Sandy Bridge, initial Cherryview support, and other code changes.
When it comes to the Gen7 command parser, the work on it isn't yet fully complete and right now there's some outstanding performance regressions. If this work doesn't get addressed in time for the Linux 3.16 kernel, this command parser will end up being disabled by default for the time being.
The Linux 3.16 kernel will also deprecate UMS support harder with Intel only pushing their kernel mode-setting support for the past several years and trying to get the last of the Linux users off using user-space mode-setting and onto their superior KMS code-paths.
This first Intel i915 DRM driver pull request for the Linux 3.16 kernel queue can be found issued via the dri-devel mailing list.
