[RFC v3 06/22] RFC: egl/x11: Support DRI3 v1.1
Louis-Francis Ratté-Boulianne
lfrb at collabora.com
Wed Sep 27 05:28:36 UTC 2017
Add support for DRI3 v1.1, which allows pixmaps to be backed by
multi-planar buffers, or those with format modifiers. This is both
for allocating render buffers, as well as EGLImage imports from a
native pixmap (EGL_NATIVE_PIXMAP_KHR).
