Hi Linus, please pull from: git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-idle-2.6.git idle-release Two regressio fixes for those cutting over to intel_idle from acpi_idle, both are candidates for 2.6.35.stable. First, if you have a Lenovo S10-3 netbook, you could not boot. Second, intel_idle was not as quiet as acpi_idle on multi-core. Plus some low risk fluff patches to get out of the way. This will update the files shown below. thanks! -- Len Brown Intel Open Source Technology Center ps. individual patches are available on linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx and a consolidated plain patch is available here: http://ftp.kernel.org/pub/linux/kernel/people/lenb/idle/patches/2.6.36/idle-release-2.6.36-rc6.diff.gz drivers/acpi/processor_driver.c | 2 +- drivers/cpuidle/governors/menu.c | 2 +- drivers/idle/intel_idle.c | 20 +++++++++++++++----- drivers/pci/quirks.c | 20 ++++++++++++++++++++ include/linux/cpuidle.h | 1 + 5 files changed, 38 insertions(+), 7 deletions(-) mode change 100755 => 100644 drivers/idle/intel_idle.c through these commits: Len Brown (2): intel_idle: PCI quirk to prevent Lenovo Ideapad s10-3 boot hang acpi_idle: add missing \n to printk Lucas De Marchi (1): cpuidle: Fix typos Namhyung Kim (1): intel_idle: add missing __percpu markup Suresh Siddha (1): intel_idle: Voluntary leave_mm before entering deeper Thomas Weber (1): intel_idle: Change mode 755 => 644 with this log: commit 6110a1f43c27b516e16d5ce8860fca50748c2a87 Author: Suresh Siddha <suresh.b.siddha@xxxxxxxxx> Date: Thu Sep 30 21:19:07 2010 -0400 intel_idle: Voluntary leave_mm before entering deeper 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...

This occurs when entering ATM-C4 for the first time, unless BM_STS is first cleared. acpi_idle doesn't see this because it first checks and clears BM_STS, but it would hit the same hang if that check were disabled. http://bugs.meego.com/show_bug.cgi?id=7093 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/634702 Signed-off-by: Len Brown <len.brown@xxxxxxxxx> _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
