Subject: [PATCH 0/5][RFC] Use per cpuidle_device states
Date: Wed, 25 Jul 2012 12:45:57 +0200	[thread overview]
Message-ID: <1343213162-8064-1-git-send-email-daniel.lezcano@linaro.org> (raw)

Since commit 46bcfad7a819bd17ac4e831b04405152d59784ab,
        cpuidle: Single/Global registration of idle states

we have a single registration for the cpuidle states which makes
sense. But now two new architectures are coming: tegra3 and big.LITTLE.

These architectures have different cpus with different caracteristics
for power saving. High load => powerfull processors, idle => small processors.

That implies different cpu latencies.

This patchset present a simple way to keep the current behavior as introduced
by Deepthi without breaking the drivers and add the possibility to specify a
per cpu states.

Daniel Lezcano (5):
  acpi : move the acpi_idle_driver variable declaration
  acpi : move cpuidle_device field out of the acpi_processor_power
    structure
  cpuidle : add a pointer for cpuidle_state in the cpuidle_device
  cpuidle : use per cpuidle device cpu states
  cpuidle : add cpuidle_register_states function
