Intel Lands First Round Of Graphics Work For Linux 4.5, Includes Kaby Lake

The first batch of Intel DRM graphics driver changes targeting the Linux 4.5 kernel have landed into DRM-Next.

First and foremost, there's the basic support for Kabylake. Kabylake is the 2016 successor to Skylake that Intel squeezed in for release before the originally expected Cannonlake. Kaby Lake will stick to 14nm and add native USB 3.1, HDCP 2.2, VP9 and HEVC 10-bit hardware decoding, and more. The graphics and video capabilities are expected to be faster than Skylake, but no drastic underlying changes. Intel has been rolling out open-source patches for Kabylake over the past month; Kabylake is considered to be just "Gen 9.5" graphics compared to "Gen 9" of Skylake.

Besides the initial Kaby Lake graphics support in Linux 4.5, this initial DRM update has a number of fixes, typesafe register MMIO functions, Panel Self Refresh (PSR) improvements, DisplayPort compliance improvements, and a number of other low-level changes.
