Hi,

New version of the DRM fences patches with all comments on v7 adressed. Please
refer to the cover letter[1] in a previous version to check for more details.

The changes since the last version can be seen in commit message on each patch.

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:

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!
