Experimental DragonFlyBSD Code Adds Broadwell Graphics

DragonFlyBSD developers continue porting over code from the Linux kernel's i915 DRM driver for supporting newer Intel graphics features on BSD. The latest work is for matching the DragonFlyBSD's ported Intel driver up through the code found in the Linux 3.14 kernel.

The result of the latest drm/i915 porting to DragonFlyBSD is making the GEM code paths more similar to Linux for better stability and performance, bug fixes and performance improvements for all supported GPUs, RC6 power-savings by default, and added support for Intel Broadwell GPUs.

This new i915 code hasn't yet been merged into the mainline DragonFlyBSD kernel but is currently in a testing branch. It's great to see the DragonFlyBSD developers moving forward in their Linux DRM driver porting and are starting to get closer to having their ported driver in a state that's closer to the upstream Linux kernel Git.
