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...
Code:OpenGL vendor string: X.Org OpenGL renderer string: Gallium 0.4 on AMD JUNIPER OpenGL version string: 3.0 Mesa 8.1-devel (git-cf76edd) OpenGL shading language version string: 1.30
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)
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.

It needs a recent libdrm (>=2.4.38) and 3.5 or 3.6 kernel IIRC (I have 3.6)
