intel_idle: disable module support 2010-08-14T18:40:36+00:00 Len Brown len.brown@intel.com 2010-08-14T18:40:36+00:00 6ce9cd8669fa1195fdc21643370e34523c7ac988 Right now the module capability is cauing more trouble than it is worth. At least one distro built intel_idle as a module where it lost the init race with ACPI, making it useless. Make intel_idle bool so that if you select it, you will use it. We can restore module capability after cpuidle is enhanced to handle run-time changing of idle drivers. Signed-off-by: Len Brown <len.brown@intel.com>

intel_idle: native hardware cpuidle driver for latest Intel processors 2010-05-28T18:26:20+00:00 Len Brown len.brown@intel.com 2010-03-08T19:07:30+00:00 2671717265ae6e720a9ba5f13fbec3a718983b65 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>
