[ofa-general] Re: libmlx4 wc flash

[Roland Dreier]

By the way, do you know what the best way to flush WC buffers for i386
is?  I know on x86-64 sfence is the way to go, and on ia64 I think we
want fc, but I'm not sure what the right thing is for for old 32-bit
processors.

Also, does it make sense to think about using non-temporal stores
(movntq) to get the effect of WC without having to worry about setting
up PAT?
