My hope was (as you can see in the last patch) to enable this for all drivers that support MS textures. I've got nv50/nvc0/r600g covered.
RadeonSI will have to read the data from the texture descriptor. I'm totally unfamiliar with LLVM, the descriptor format, etc. Hopefully someone will be able to write an appropriate patch. SVGA seems to support ms textures, but I didn't see anything in its virtual ISA that would fit. VMWare folk -- is this going to be easy to add? Or do I need to add a new PIPE_CAP?
