Is there any benefit to it?
more than 255 pci buses. think about if you have 32 ht chains...
Sorry to be dense, but how do you have more than 4 HT chains? Aren't there are only 8 nodes allowed in a system (3 links per node)?
If you took out the middle links in an 8-way design I guess you could have 8 HT chains.
And I guess if you made it into a chain you could have 10.
I'm obviously missing something, because it seems silly.
amd Family 10h cpu could support 16 domains ( 4 bits for domain...)

Could you point me to a section of a BKDG? I found something about protection domains, but it looked like it was only for DMA.
I don't see how our current PCI functions could use domains.
