From 720f1c3010db6a411358b962a2007969117840bc Mon Sep 17 00:00:00 2001 From: Thomas Renninger Date: Fri, 7 Jan 2011 11:29:43 +0100 Subject: [PATCH] cpuidle: Rename X86 specific idle poll state[0] from C0 to POLL C0 means and is well know as "not idle". All documentation out there uses this term as "running"/"not idle" state. Also Linux userspace tools (e.g. cpufreq-aperf and turbostat) show C0 residency which there is correct, but means something totally else than cpuidle "POLL" state.
