I think it's a factor of your chipset. For example, my laptop: $ grep MSI /proc/interrupts 26: 33095 33046 PCI-MSI-edge eth0 27: 127014 126190 PCI-MSI-edge ahci 28: 0 0 PCI-MSI-edge ahci 29: 0 0 PCI-MSI-edge ahci 31: 525988 518310 PCI-MSI-edge iwlagn I know my G33-based desktop also distributes interrupts equally across all four cores. It is, of course, possibly to manually set the affinity, and perhaps that's what you're seeing. > > Did you see this is patch 1/6? ;-) > > yes....after I hit send and continued reviewing the rest of the patches. ;) It's good to know somebody looked at patches 2-6 because I've not had any comments yet. -- Matthew Wilcox Intel Open Source Technology Centre "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours.
