Subject: [PATCH v10 0/3] drm: add explicit fencing

From: Gustavo Padovan <gustavo.padovan@...labora.co.uk>

Hi,

Another iteration after comments on v8 and v9. Please refer to the cover
letter[1] in a previous version to check for more details.

The only changes in this series are in patch 3/3, see commit message for details.

Robert Foss managed to port Android's drm_hwcomposer to the new HWC2 API and
added support to fences. Current patches can be seen here:

https://git.collabora.com/cgit/user/robertfoss/drm_hwcomposer.git/log/?h=hwc2_fence_v1

He ran AOSP on top of padovan/fences kernel branch with full fence support on
qemu/virgl and msm db410c. That means we already have a working open source
userspace using the explicit fencing implementation.

Also i-g-t testing are available with all tests suggested in v7 included:

Please review!

Gustavo
