Right now from configure.ac I've got either targeting-hardware mode, or targeting-simulator mode. What I need to add is something in between, where we use the ioctls from simulator mode so that people can run the driver on i965 systems, and then just don't make the simulator calls at the very end of the drawing pipeline since you don't have the simulator. Then people could even run shader-db without having the actual hardware, and that would get a lot of coverage of compiler changes. You could knock this together with some #ifdefs around all 7 mentions of "simpenrose", but I'll try to get a clean patch sent out. I'm just trying to decide whether this should be a --enable argument or "oh, hey, you're not on arm, you must want either simulator or everything-but-simulator mode" I'd also like something a bit nicer than my symlink trick for loading the driver (right now I link the built vc4_dri.so to i965_dri.so in a subdirectory, and LIBGL_DRIVERS_PATH it). Maybe if I getenv() a name From loader.c for computing driver name, I could also skip a bunch of the i965 symbols I have to add.
