[PATCH v11 0/3] drm: add explicit fencing

[Gustavo Padovan]

From: Gustavo Padovan <gustavo.padovan@xxxxxxxxxxxxxxx>

Hi,

Hopefully the last version of the patches with the two comments from Brian
in the previous version addressed.

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!
