One month after Rob Clark began developing his Freedreno Gallium3D stack for Qualcomm's Adreno A3xx hardware, he's beginning to achieve visual success. While the code hasn't yet been merged into mainline Mesa, on an A320 as found on the Google Nexus 4 he has es2gears (the OpenGL ES version of glxgears) successfully running on this open-source code.
Rob shared this milestone for his ARM SoC open-source graphics driver on his blog. Right now this code is living on a GitHub branch but will be merged into mainline Mesa in due time for this reverse-engineered Qualcomm driver. The mainline Gallium3D driver at this point is supporting the Adreno 200 series quite well.
Other hardware where the Adreno A320 is found besides the Nexus 4 is the LG Optimus G, Sony Xperia SP, ZTE Grand S, Sony Xperia Z, and many other Snapdragon S4 Pro mobile devices.
