With Intel's first drm-intel-next pull request as well as the drm-misc code updates also sent in by Intel DRM maintainer Daniel Vetter, there are already over 550 patches queued up for this next kernel cycle! Looks like Linux 4.12 could be big on the DRM front especially as Intel will have more pull requests, AMD might have DC/DAL and even Vega for 4.12, and Nouveau will have the newly-published Pascal acceleration code.
Within this first Intel DRM-Next pull request are more atomic improvements, GPU reset improvements, atomic mode-setting being enabled by default for Ironlake hardware and newer, some power management improvements, continued work on Geminilake enablement that was first introduced in Linux 4.11, context switching improvements, and a range of other low-level code improvements.
A listing of these initial Intel DRM changes for Linux 4.12 can be found via this pull request.
There is also drm-misc-next sent in this week with some VC4 improvements, extended frame-buffer fbdev support, and a range of other common code Direct Rendering Manager code improvements.
