(506 pages).  I think there's a lack of documentation on GCN, though.

I think we should start by reviewing code generated from OpenCL source,
much like we review x86-64 assembly code generated by gcc.

Does this mean it was no longer stable at 1250 MHz core?  Are you
referring to my test from yesterday, where I got ASIC hang at 1250 MHz
after 3.5 minutes?  If so, that does not tell me much because I also got
a system reboot after 15 minutes running the same code at stock clocks.

BTW, changing the memory clock back and forth did not affect bf-opencl
performance at all, which confirms that it indeed does not use global
memory much (in the current code revision).  That's good.
