sys/pci pcisupport.c
Log:
SMP Natoma motherboards cannot know if you are booting a UP or SMP OS. This
mod makes sure that the Natoma chipset is set into the correct mode. In
the case of my P6DNF, when booting a UP kernel, I see a substantial improvement
in the latency of certain operations. It appears that the cache hit
latency is curiously improved the most, per lat_mem_rd.
