[PATCH weston v2 0/8] Generic Wayland dmabuf protocol

[Pekka Paalanen]

From: Pekka Paalanen <pekka.paalanen at collabora.co.uk>

Hi all,

here is the v2 iteration of the Wayland protocol extension for generic sharing
of dmabufs between clients and the compositor.

The RFCv1 can be found at
http://lists.freedesktop.org/archives/wayland-devel/2014-December/019006.html

The related tracking bug is
https://bugs.freedesktop.org/show_bug.cgi?id=83881


The major changes compared to RFCv1 are:
- use drm_fourcc.h to define format codes
- support FB modifiers and y-flip
- simplified protocol
- improved documentation
- flags for interlaced buffer content

As you can see, we have dropped the "RFC" status from this series now. We think
this is in a good enough shape to be merged into Weston as an experimental
protocol and implementation. Obviously we are still lacking on:
- agreed ways to flush caches (what can we cache? EGLImages? DRM FBs?)
- enumerating supported formats
- supported FB modifiers?
- do all imports in compositor before-hand, not as-needed
  (the import as DRM FB)
- EGL doesn't support dmabuf import with modifiers yet
- a test application not specific to (Intel) hardware (vivid?)
- compositor-drm.c's import of dmabuf needs a rewrite to bypass GBM
  (to be done after atomic lands)
- compositor-drm.c support for multi-planar buffers
