From e9efed3b80a83e44b98fc626f3268ae072550b84 Mon Sep 17 00:00:00 2001 From: Nathan Lynch Date: Sun, 27 Jul 2008 15:24:54 +1000 Subject: powerpc: Make core id information available to userspace Existing Open Firmware practice is to report each processor core as a separate node in the device tree. Report the value of the "reg" OF property corresponding to a logical CPU's device node as the core_id attribute in /sys/devices/system/cpu/cpu*/topology/core_id.
