[Mesa-users] Radeon HD 7870 | Geo Shaders Ext | Fedora 21

[AxP]

Hey guys,

the last few days I was wondering if I had a working geometry shader 
extension and then in which mesa version it would come. Maybe I am 
overlooking something. I tried to find the extension with glxinfo and 
tried a shader demo of opentk.
I own a Radeon HD 7870 and I am using the free radeon drivers that come 
with fedora, so radeon. I found that the shader should be there for 
southern island, like written here: 
http://mesamatrix.net/#Version_OpenGL3.2-GLSL1.50_Extension_Geometryshaders 
and http://www.x.org/wiki/RadeonFeature/
So, Problem is that I have no clue if the feature is actually available, 
which version of mesa, wether there was some news about this (Did google 
or duckduckgo it :P) or or or. So Im kinda confused because of all the 
green fields on the feature site.
Do you know if the geometry shader extension is working with the free 
driver?

Many thanks,
AxP
