Christian König landed a number of RadeonSI driver fixes today into mainline Mesa. The German developer working for AMD fixed up shader size and handling, vetex buffer and elements, dummy export in shaders, shader binding, stencil op mapping, db and stencil setup, and other work. This was more than 100 lines of changes to this open-source Gallium3D driver being developed for the AMD Radeon HD 7000 series and future hardware generations.
With the last commit to RadeonSI from this morning, the commit message reads:
v2: fix tiling for small pitches, that finally makes glxgears and readPixSanity workNow finally six months after the hardware first began to ship, the Radeon HD 7000 series graphics cards can handle the simple glxgears demo test. Hopefully hitting the rest of the OpenGL milestones for the RadeonSI Gallium3D driver will now come much quicker, though it's still unlikely to find the support primed for end-users by next month's Mesa 8.1 release.
