Intel DRM-Next Performance Tests With Skylake (Linux 4.8)

Material queued up so far in DRM-Next for Linux 4.8 includes better DisplayPort++ dongle support, L3 cache tuning, continued GuC work, and a whole lot more. There is also GVT-g para-virtualized GPU support.
Curious about any performance improvements (or regressions) that may have landed, I ran some benchmarks today on a Core i5 Skylake system with HD Graphics 530 while comparing Linux 4.6.0 vs. Linux 4.7 Git vs. DRM-Next. The tests were used in conjunction with Mesa 12.1-dev.
But there's virtually no performance difference on the kernel side between Linux 4.6 and what will be landing in Linux 4.8, at least for this i5-6600K HD Graphics 530 box. If you are curious for more details and additional (flat) test results, stop by OpenBenchmarking.org. At least this next kernel version will be bringing features like GVT-g to make-up for the lack of any latest performance improvements in DRM space.
