Subject: X86 cpuidle cleanups V3
Date: Tue, 17 Jan 2012 22:40:06 +0100 [thread overview]
Message-ID: <1326836408-23177-1-git-send-email-trenn@suse.de> (raw)
V3: - Fix a critical typo in
[PATCH 1/2] ACPI processor: Remove unneeded variable passed by
- Make checkpatch clean
This prepares physical CPU hotplug functionality for the intel_idle
and acpi_processor (cpuidle/throttling) driver.
This still needs:
- split up of processor_add function into
1) A minimum part just registering the core, not trying to init
anything, because cpu_data(cpu) is not initialized yet
(feature flags, model, family, all zero), MSRs cannot get
executed as the cpu is still offline at ACPI hotplug time
2) A part doing throttling/cpuidle intitialization when it's
safe to do so
- Only do minimum registration at ACPI CPU hotplug event time. Delay
and do full cpuidle/throttling init when the physically hotplugged
CPU is onlined via echo 1 >/sys/../cpuX/online the first time
