Intel Geometry Shaders Might Be Ready For Mesa

Holding back Mesa from full support for OpenGL 3.2 has been support for OpenGL Geometry Shaders (and some GLSL 1.50 work). Geometry shaders have been toyed with for quite a while inside Mesa and this week is a new set of thirty patches out of Intel for implementing GS driver support for Ivy Bridge and Haswell hardware.

Sent over earlier in the week by Intel OTC's Paul Berry was the initial geometry shader support for Ivy Bridge and Haswell graphics hardware. Berry says basic geometry shader functionality works but still there's some missing items like sampling and some primitive work plus the need for a lot more testing.

By the time of the Mesa 9.3/Mesa 10.0 release, hopefully OpenGL 3.2's Geometry Shader work will be worked out for Intel and also the Radeon/Nouveau Gallium3D drivers...
