| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The idea behind power policy was that it would start off as a modparam, and then hook into the new "global" in-kernel power vs energy tunable. But that tunable isn't happening, so delete the hook here. With the policy hook gone, the sub-state choice functions do not do anything useful, so delete them from the critical path. To handle sub-states in the future, we will advertise them with dedicated cpuidle_state entries. That is necessary because some of the sub-states will have substantially different properties than their peer sub-states. Signed-off-by: Len Brown <len.brown@intel.com>

* intel_idle: native hardware cpuidle driver for latest Intel processorsLen Brown2010-05-281-0/+461
This EXPERIMENTAL driver supersedes acpi_idle on Intel Atom Processors, Intel Core i3/i5/i7 Processors and associated Intel Xeon processors. It does not support the Intel Core2 processor or earlier. For kernels configured with ACPI, CONFIG_INTEL_IDLE=y allows intel_idle to probe before the ACPI processor driver. Booting with "intel_idle.max_cstate=0" disables intel_idle and the system will fall back on ACPI's "acpi_idle". Typical Linux distributions load ACPI processor module early, making CONFIG_INTEL_IDLE=m not easily useful on ACPI platforms. intel_idle probes all processors at module_init time. Processors that are hot-added later will be limited to using C1 in idle. Signed-off-by: Len Brown <len.brown@intel.com>
