More Intel DRM Changes For Linux 4.9, Including DMA-BUF Implicit Fencing

For Linux 4.9 we already saw some Intel DRM changes in early August, a second batch of feature changes in late August for DRM-Next, and out this morning is another batch of i915 DRM driver changes being queued for the upcoming Linux 4.9 kernel merge window.

There are a lot of changes with this latest pull request to DRM-Next. Some highlights include more virtual GPU (vGPU) support work, continued Skylake fixes, support for synchronous GPU reset handling as an effort to improve the error recovery code, preparations for non-blocking Execlist submissions, and full DMA-BUF implicit fencing support.

Some of the other Intel DRM changes include refactoring the SSEU code, GuC dmesg improvements, DPLL code changes, DisplayPort link fixes, and a variety of other bug fixes and code refactoring changes.

More details on this latest batch of Intel graphics driver feature changes for Linux 4.9 via this pull request to DRM-Next. Linux 4.9 will get underway in October while its release will be around late November or early December.
