[Mesa-dev] [PATCH 0/5] wayland: handle interlaced pictures

[Gwenole Beauchesne]

Hi,

Here is series of patches that brings support for interlaced surfaces in
Wayland. Current implementation involves Intel GenX driver.

Patch 1 makes it possible to attach a "picture-structure" property to
Wayland/DRM buffers. The way to do so has the benefit of allowing this
property to RGB surfaces too.

Patch 3 is not strictly needed but introduces a query option for this
"picture-structure" property. This is implemented with a new
EGL_TEXTURE_STRUCTURE_WL token.

Patch 4 adds the new picture structure flags to DRIimage. I didn't want to
change the createSubImage() interface, so I just chose to add new flags. Those
flags are to be combined with the actual image format. I don't mind either
way.

Patch 5 implements deinterlacing in Gen driver. Only tested on Ivy Bridge.

Regards,
Gwenole Beauchesne (5):
  wayland-drm: add picture structure.
  wayland: handle picture structure.
  wayland: support EGL_TEXTURE_STRUCTURE_WL queries for wl_buffer.
  __DRIimage: version 6, add new picture structure.
  intel: implement picture structure.
