intel_idle: prevent SKL-H boot failure when C8+C9+C10 enabled

2016-04-12T14:33:48Z

commit d70e28f57e14a481977436695b0c9ba165472431 upstream. Some SKL-H configurations require "intel_idle.max_cstate=7" to boot. While that is an effective workaround, it disables C10. This patch detects the problematic configuration, and disables C8 and C9, keeping C10 enabled. Note that enabling SGX in BIOS SETUP can also prevent this issue, if the system BIOS provides that option. https://bugzilla.kernel.org/show_bug.cgi?id=109081 "Freezes with Intel i7 6700HQ (Skylake), unless intel_idle.max_cstate=7" Signed-off-by: Len Brown Signed-off-by: Greg Kroah-Hartman

intel_idle: Skylake Client Support

2015-08-16T02:10:26Z

Skylake Client CPU idle Power states (C-states) are similar to the previous generation, Broadwell. However, Skylake does get its own table with updated worst-case latency and average energy-break-even residency values. Signed-off-by: Len Brown

intel_idle: allow idle states to be freeze-mode specific

2015-07-26T16:43:45Z

intel_idle uses a NULL "enter" field in a cpuidle state to recognize the invalid entry terminating a variable-length array. Linux-4.0 added support for the system-wide "freeze" state in cpuidle drivers via the new "enter_freeze" field. The natural way to expose a deep idle state for freeze, but not for run-time idle is to supply "enter_freeze" without "enter"; so we update the driver to accept such states. Signed-off-by: Len Brown

Pull power management and ACPI updates from Rafael Wysocki: "These are mostly fixes and cleanups all over, although there are a few items that sort of fall into the new feature category. First off, we have new callbacks for PM domains that should help us to handle some issues related to device initialization in a better way. There also is some consolidation in the unified device properties API area allowing us to use that inferface for accessing data coming from platform initialization code in addition to firmware-provided data. We have some new device/CPU IDs in a few drivers, support for new chips and a new cpufreq driver too. Specifics: - Generic PM domains support update including new PM domain callbacks to handle device initialization better (Russell King, Rafael J Wysocki, Kevin Hilman) - Unified device properties API update including a new mechanism for accessing data provided by platform initialization code (Rafael J Wysocki, Adrian Hunter) - ARM cpuidle update including ARM32/ARM64 handling consolidation (Daniel Lezcano) - intel_idle update including support for the Silvermont Core in the Baytrail SOC and for the Airmont Core in the Cherrytrail and Braswell SOCs (Len Brown, Mathias Krause) - New cpufreq driver for Hisilicon ACPU (Leo Yan) - intel_pstate update including support for the Knights Landing chip (Dasaratharaman Chandramouli, Kristen Carlson Accardi) - QorIQ cpufreq driver update (Tang Yuantian, Arnd Bergmann) - powernv cpufreq driver update (Shilpasri G Bhat) - devfreq update including Tegra support changes (Tomeu Vizoso, MyungJoo Ham, Chanwoo Choi) - powercap RAPL (Running-Average Power Limit) driver update including support for Intel Broadwell server chips (Jacob Pan, Mathias Krause) - ACPI device enumeration update related to the handling of the special PRP0001 device ID allowing DT-style 'compatible' property to be used for ACPI device identification (Rafael J Wysocki) - ACPI EC driver update including limited _DEP support (Lan Tianyu, Lv Zheng) - ACPI backlight driver update including a new mechanism to allow native backlight handling to be forced on non-Windows 8 systems and a new quirk for Lenovo Ideapad Z570 (Aaron Lu, Hans de Goede) - New Windows Vista compatibility quirk for Sony VGN-SR19XN (Chen Yu) - Assorted ACPI fixes and cleanups (Aaron Lu, Martin Kepplinger, Masanari Iida, Mika Westerberg, Nan Li, Rafael J Wysocki) - Fixes related to suspend-to-idle for the iTCO watchdog driver and the ACPI core system suspend/resume code (Rafael J Wysocki, Chen Yu) - PM tracing support for the suspend phase of system suspend/resume transitions (Zhonghui Fu) - Configurable delay for the system suspend/resume testing facility (Brian Norris) - PNP subsystem cleanups (Peter Huewe, Rafael J Wysocki)" * tag 'pm+acpi-4.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (74 commits) ACPI / scan: Fix NULL pointer dereference in acpi_companion_match() ACPI / scan: Rework modalias creation when "compatible" is present intel_idle: mark cpu id array as __initconst powercap / RAPL: mark rapl_ids array as __initconst powercap / RAPL: add ID for Broadwell server intel_pstate: Knights Landing support intel_pstate: remove MSR test cpufreq: fix qoriq uniprocessor build ACPI / scan: Take the PRP0001 position in the list of IDs into account ACPI / scan: Simplify acpi_match_device() ACPI / scan: Generalize of_compatible matching device property: Introduce firmware node type for platform data device property: Make it possible to use secondary firmware nodes PM / watchdog: iTCO: stop watchdog during system suspend cpufreq: hisilicon: add acpu driver ACPI / EC: Call acpi_walk_dep_device_list() after installing EC opregion handler cpufreq: powernv: Report cpu frequency throttling intel_idle: Add support for the Airmont Core in the Cherrytrail and Braswell SOCs intel_idle: Update support for Silvermont Core in Baytrail SOC PM / devfreq: tegra: Register governor on module init ...

intel_idle: mark cpu id array as __initconst

2015-04-11T00:25:01Z

The CPU ids are only tested in intel_idle_probe() which is itself an __init function. For the MODULE_DEVICE_TABLE() file2alias doesn't care about the section, just about the symbol name. So it's safe to mark the cpu id array as __initconst so its memory can be released after initialization is done. Signed-off-by: Mathias Krause Signed-off-by: Rafael J. Wysocki
