I can't really tell how the spe_id field is used on our platform. It looks like the value comes comes from a property in the open-firmware device-tree, but looking at the values in the device-tree, it's not obvious how or if the spe_id value relates to the simple SPU number. Sorry I can't give you a better answer. -- Kevin Corry [EMAIL PROTECTED] http://www.ibm.com/linux/ _______________________________________________ perfmon mailing list [email protected] http://www.hpl.hp.com/hosted/linux/mail-archives/perfmon/
