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 logical and physical processors themselves. For performance reasons, the kernel should schedule processes/threads to execute on physical processors first, followed then by logical processors.
Any help is greatly appreciated. Regards,
