I'll have to ask one of our devs who knows autoconf really well. I figure that's probably a good place to catch something like this. Have configure check /proc/cpuinfo and look for "R10000", and if it finds it, mod CFLAGS to pass -DR10k_LLSC_WAR, and #ifdef on that in atomic.h.

Sound plausible?


And any idea if uClibc will need similar mods?

It needs a similiar change to support R10000 v2.5.

Thought it would.  I'll keep this in mind if we ever get that running again.



Cheers,
