[Mesa-dev] [PATCH 0/5] OpenGL ES improvements

[Roland Scheidegger]

Actually, this stuff is mandatory not just for GLES but also for OGL 4.3
(and some more formats still for 4.4). So even more surprising it's not
supported by at least CIK. I guess though it's hacked around by the
binary drivers just like here...

Textures of such formats are loaded as plain R/RG/RGBA in st/mesa due to lack of hardware support. There is no real gallium support for the new formats. The i965 driver is doing the same thing.
