Intel Continues Landing New i915 DRM Features For Linux 4.15

Written by Michael Larabel in Intel on 20 October 2017 at 06:20 AM EDT. 1 Comment
Jani Nikula has sent in another drm-intel-next update for David Airlie's DRM-Next tree. They continue prepping more updates to their Direct Rendering Manager (DRM) for targeting the upcoming Linux 4.15 cycle.

There have already been several Intel "i915" DRM driver updates queued in DRM-Next for this new kernel version. Past pulls have included marking Coffeelake graphics as stable, continued Cannonlake "Gen 10" graphics enablement, various display improvements, and quite a lot of other low-level code improvements.

The Intel pull request submitted for DRM-Next on Thursday was anticipated to be the last of new feature work for 4.15. That's because David Airlie tends to frown upon new feature work landing in DRM-Next after -RC6 of the current Linux kernel cycle, with that milestone happening on Sunday. But Intel is looking at squeezing in one final pull request next week.

Arguably most notable with this latest pull request is transparent huge-pages support but there is also preemption support for execlists as well as optimizations, user-defined priority support for the scheduler, display fixes, HuC/GuC firmware refactoring, DisplayPort Multi-Stream Transport (DP MST) fixes, and quite a variety of other low-level driver improvements.

The dozens of changes in this latest pull request are outlined here.
