Can anyone tell me if netBSD supports the dual-Xeon architecture
with E7500 chipset? This would require netBSD to be SMP capable
at a minimum (which I believe it is?).
The Xeon has a feature called Hyper-Threading which enables the
single physical processor to appear as two logical processors
(completely transparent to the OS). The only requirement is for
the OS to detect the presence of the logical processors by reading
the ACPI (Advanced Configuration and Power Interface) table maintained
by the BIOS.
Can netBSD already read the ACPI?
My last question is whether or not netBSD can differentiate between the
and physical processors themselves. For performance reasons, the
should schedule processes/threads to execute on physical processors
followed then by logical processors.
Any help is greatly appreciated.
