I think the easiest way would be to look in the /proc/device-tree, for the info given to you by the OF. This naturally will probably only work on newworld and chrp, not sure about oldworld and prep SMP boxes. Anyway, on my pegasos2/G4, i have : $ ls /proc/device-tree/cpus/ #address-cells #cpus linux,phandle name PowerPC,74x7 #size-cells Presumably you have two processor nodes on SMP boxes. Also, another way would (maybe) to look at the content of #cpus : $ hexdump /proc/device-tree/cpus/#cpus 0000000 0000 0001 0000004 So, on my box, #cpus will contain 1, and presumably on SMP boxes, it will contain 2 or more. I have not tested this, but please check on your system. Friendly, Sven Luther
