[PATCH v17 00/14] DRM backend planes and modifiers

[Daniel Stone]

Hi,
Another re-send after Pekka's comments on the modifiers patches. Patches
01-12 from the last series were merged after the last round.

Patch 1 is new; patches 2 and 3 were extracted from patches 5 and 6.

Patches 4-6 have otherwise seen changes after Pekka's review; all the
comments were addressed.

Patches 7-14 are unchanged from the previous submission, except where a
rebase may have modified them.

This iteration of the series is available from:
    https://gitlab.collabora.com/daniels/weston/commits/wip/2018-07/atomic-v17

The tree on GitLab includes a 'drm debug' patch at the top, which adds a
lot of debug spew to the KMS backend. It is very useful to cherry-pick
this patch and include any debug information when reporting bugs on this
series, however the log volume is great enough that it can visibly slow
the compositor.

Cheers,
Daniel
