    intel_idle: native hardware cpuidle driver for latest Intel processors · 26717172
    Len Brown authored
    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.
