Then where does the firmware come from?  I've been glancing at the AMD
documentation for the R600 and I'd like to figure out why the firmware
seems to be running in an infinite loop without ever halting, and
driving the temperature of my card over 80 C, but I need the original
assembly code for that.

So it is kind of like a barrier in the IO world?  You put a dozen
commands into the pipeline and then a fence, and when they all complete,
the fence gives you feedback so you know?
