Radeon & AMDGPU DRM Fixes Queue Up For Linux 4.2

While the Linux 4.2 kernel merge window isn't yet over, AMD developers already have amassed a collection of fixes for the Radeon and AMDGPU DRM drivers following the big DRM pull.

The feature DRM pull for Linux 4.2 brought the new AMDGPU driver for supporting the very latest and future AMD graphics processors. This pull also brought VCE1 video encode and other functionality to the longstanding Radeon DRM driver. This new pull sent into DRM subsystem maintainer David Airlie has fixes for both of these open-source AMD kernel graphics drivers.

The fixes for this latest pull vary and include fixing Radeon audio support, hibernation/suspend fixes, AMDGPU ioctl optimizations/fixes, VCE command stream checker improvements, and other bug-fixes. In total these changes for Linux 4.2 add another 400+ lines of code between these two DRM drivers.

These changes are going to be queued up into Airlie's DRM tree and should be called for merging into the mainline Linux 4.2 kernel in the days ahead. The full list of changes can be found via that pull request. As always, we continue carrying out daily kernel and Mesa graphics benchmarks in a fully-automated manner with the newest Git code over on LinuxBenchmarking.com.
