Subject[PATCH v8 00/13] V4L2 Explicit Synchronization
Date
From: Gustavo Padovan <gustavo.padovan@collabora.com>

Hi,

So v8 is finally out addressing the comments from the previous version[1].
For more info see v5 cover letter[2]. The most important points I address
here is the handling of fences that signal with error to follow Hans
suggestion. I also added V4L2_CAP_FENCES to all vb2 drivers and marked all
codec and cobalt as unordered. More specific changelog are noted on the
patches itself.

The first 3 patches are just clean ups in preparation to add the new cap flag
and can go upstream earlier. Then there are patches to add unordered info,
the actual fences implementation and later the V4L2_CAP_FENCES flag.
The last patch contains the Documentation.

You can find the code at:

https://gitlab.collabora.com/padovan/linux/tree/v4l2-fences

The test tools I've been using are:
https://gitlab.collabora.com/padovan/drm-v4l2-test
https://gitlab.collabora.com/padovan/v4l2-fences-test

Please review,

Gustavo
