How difficult is auto-tune to code. Set voltage restart hash for 5 minutes count error rate per board restart try new on etc etc? Just curious how it is done.

not in C code, but rather in bash script.
i've wrote some scripts that change freq in /config/cgminer.conf and then restart cgminer, wait 5 minutes and check HWerrs, temperature and rate for that freq.
from hi values of freq to lower ones - when you get HWerrs lower than some limit (half percent, for example) - you get right freq value.
voltage has to be changed via set_voltage program, and then start freq-optimization script again.
