Intel Is Prepping A Final Batch Of Feature Changes For Linux 4.15 DRM

Intel has been sending in feature updates for their Direct Rendering Manager driver of new material that will debut in Linux 4.15. A third and final feature update is expected next week for DRM-Next.

The feature work thus far has included furthering their "Gen 10" Cannonlake graphics support, the kernel bits for ARB_timer_query handling to then be exposed in Mesa, display fixes, some improvements around GPU clock boosting, and then in the most recent pull request it no longer treats Coffee Lake as "alpha" support among other code improvements.

Intel's Jani Nikula sent out on Thursday a new drm-intel-testing branch and indicated in a separate mailing list message to David Airlie that it will serve as the final Intel i915 feature updates with one last pull request to be sent in next week.

This latest batch of testing code includes transparent huge-pages support, execlist preemption support, user-defined priorities for its scheduler, more display fixes, HuC/GuC firmware refactoring, and a variety of other code improvements. The transparent huge-pages is likely the most interesting of this new batch to ultimately be queued for Linux 4.15.

The Linux 4.15 merge window should open by mid-November once Linux 4.14 LTS is finally in a state to be released.
