From 2671717265ae6e720a9ba5f13fbec3a718983b65 Mon Sep 17 00:00:00 2001 From: Len Brown Date: Mon, 8 Mar 2010 14:07:30 -0500 Subject: intel_idle: native hardware cpuidle driver for latest Intel processors 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.
