If we use the LAPIC timer during ATOM C2 on some nvidia chisets, the system stalls. https://bugzilla.kernel.org/show_bug.cgi?id=21032 Signed-off-by: Len Brown <len.brown@intel.com> Cc: Tom Gundersen <teg@jklm.no> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> 2010-10-09T02:16:27Z Len Brown len.brown@intel.com 2010-10-05T17:43:14Z urn:sha1:7fcca7d900957b43c84da171b750afcf1682808a ATM-C6 was commented out, pending public documentation. https://bugzilla.kernel.org/show_bug.cgi?id=19762 Tested-by: Dennis Jansen <Dennis.Jansen@...> Signed-off-by: Len Brown <len.brown@intel.com> 2010-10-01T01:19:22Z Suresh Siddha suresh.b.siddha@intel.com 2010-10-01T01:19:07Z urn:sha1:6110a1f43c27b516e16d5ce8860fca50748c2a87 Avoid TLB flush IPIs for the cores in deeper c-states by voluntary leave_mm() before entering into that state. CPUs tend to flush TLB in those c-states anyways. acpi_idle does this with C3-type states, but it was not caried over when intel_idle was introduced. intel_idle can apply it to C-states in addition to those that ACPI might export as C3...

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.
