Explicit Fencing For Atomic DRM Drivers Coming In Linux 4.10
Written by Michael Larabel in Linux Kernel on 17 November 2016 at 04:00 AM EST. 4 Comments
Adding to the list of new features coming for Linux 4.10 is support for explicit fencing for atomic DRM drivers.

The explicit fencing support has been a long time coming and is the work of Collabora and others. This mainline Linux kernel work is based on the work done by Google with their work on the Sync Framework for Android. Gustavo Padovan of Collabora who has been leading much of this work on fencing for the mainline Linux kernel has already written about it at length on his blog with part 1 and part 2.

The pull request for the explicit fencing was sent in today via the drm-misc-next and has already landed in DRM-Next. More details via the commit messages on out-fences support and in-fences support.
