Phoronix: Marek Lands Radeon Gallium3D MSAA Changes
Marek Olšák, the prolific independent contributor to Mesa/Gallium3D and the open-source Radeon Linux graphics driver, has landed a number of commits today in Mesa pertaining to MSAA, a.k.a. multi-sample anti-aliasing for newer Radeon GPUs...

Coolness... can anyone confirm whether this does, or does not, cause r600g on Evergreen to advertise OpenGL 3.0?

it does

Awesome. Now, on to 3.1
Looks like we need the forward compatible context support/deprecations (I've seen what I believe are commits related to this in mesa-dev), UBOs (almost done?), and Texture Buffer Objects (which I'm assuming is only done for i965).Code:GLSL 1.40 needs UBOs (in progress) Forward compatibile context support/deprecations not started Instanced drawing (GL_ARB_draw_instanced) DONE (i965, gallium, swrast) Buffer copying (GL_ARB_copy_buffer) DONE (i965, r300, r600, swrast) Primitive restart (GL_NV_primitive_restart) DONE (i965, r600) 16 vertex texture image units DONE Texture buffer objs (GL_ARB_texture_buffer_object) needs GL3.1 enabling (i965) Rectangular textures (GL_ARB_texture_rectangle) DONE (i965, r300, r600, swrast) Uniform buffer objs (GL_ARB_uniform_buffer_object) DONE (i965) Signed normalized textures (GL_EXT_texture_snorm) DONE (i965, r300, r600)

NERDGASM! *Waving hands in the air and flailing about!*
This is quite huge, we've been waiting for it for 3 years now.
Regarding 6000/5000 generation, I'll probably buy one when it's actually faster (across the board) than the 4000 generation for the FOSS drivers. But now there's simply no point.

Well...
Same commit.Code:OpenGL vendor string: X.Org OpenGL renderer string: Gallium 0.4 on AMD REDWOOD OpenGL version string: 2.1 Mesa 8.1-devel (git-cf76edd) OpenGL shading language version string: 1.30

It needs a recent libdrm (>=2.4.38) and 3.5 or 3.6 kernel IIRC (I have 3.6)
Senior Member
Actually I built it yesterday.Code:~ % pkg-config libdrm --modversion 2.4.38
But the kernel is probably build with a config similar to 3.5. Does it need some special configuration?Code:~ % uname -r 3.6.0-rc1-mainline

Do you build with the patented float feature? It's required for GL 3.0 IIRC.
