Hi, Patchbomb time, this set of patches is a first pass at add adding ARB_tessellation_shader support to the r600g driver. Only Evergreen and newer GPUs support tessellation. On any of the GPUs that support native FP64, this will enable OpenGL 4.1 on them.
The first bunch of patches are a bit of a driver rework to get things in better shape for tessellation, they shouldn't cause any regressions. This runs heaven on cayman and should pass all the piglits unless I've done something wrong. Development hit two HW programming fun times, one with tess and dynamic GPR interaction requiring disabling dynamic GPRs, and one with programming of some SIMD registers to block TESS shaders on one unit. These fixed most of the hangs we saw during development. This doesn't contain SB support yet, Glenn has started working on it. Currently tested hw: working: CAYMAN, REDWOOD, BARTS, TURKS hangs on any tessellation: CAYMAN hangs differently at least with heaven: SUMO This patchset doesn't block it on any GPUs, but when merged it probably should.
