  • 2be6d9bfe   clocksource: Select CLKSRC_MMIO where needed ... Browse Code »

    The Tegra clocksource implementation uses the clocksource_mmio helper
    functions, but currently can be configured without them, which fails:

    drivers/clocksource/built-in.o: In function `tegra20_init_timer':
    :(.init.text+0xac): undefined reference to `clocksource_mmio_init'
    :(.init.text+0x140): undefined reference to `clocksource_mmio_readl_up'

    The same problem exists for Digicolor:

    drivers/clocksource/built-in.o: In function `digicolor_timer_init':
    :(.init.text+0xfa): undefined reference to `clocksource_mmio_init'
    :(.init.text+0x14c): undefined reference to `clocksource_mmio_readl_down'

    I've inspected the Kconfig file to look for other cases that I have not
    yet run into, and added an explicit 'select' to each one to ensure we
    can successfully link the drivers.

  • 3da6d49e8   clocksource: Disallow drivers for ARCH_USES_GETTIMEOFFSET ... Browse Code »

    We can now select clocksource drivers like ti-32k and CONFIG_OF
    on ancient machines that still use gettimeoffset, and the combination
    results in a link error.

    arch/arm/kernel/built-in.o: In function `time_init':
    (.init.text+0xc28): undefined reference to `clocksource_probe'

    The reason for this is that the Makefile is hidden behind
    CONFIG_ARCH_USES_GETTIMEOFFSET, but the Kconfig file is not, and
    it has shown up just now because the ti-32k driver was added
    and can be selected using COMPILE_TEST on all platforms.

    This patch hides the Kconfig menu in CONFIG_ARCH_USES_GETTIMEOFFSET
    as well.

    Pull ARM SoC cleanups from Olof Johansson:
    "Again we have a sizable (but not huge) cleanup branch with a net delta
    of about -3k lines.

    Main contents here is:

    - A bunch of development/cleanup of a few PXA boards
    - Removal of bockw platforms on shmobile, since the platform has now
    gone completely multiplatform. Whee!
    - move of the 32kHz timer on OMAP to a proper timesource
    - Misc cleanup of older OMAP material (incl removal of one board
    file)
    - Switch over to new common PWM lookup support for several platforms

    There's also a handful of other cleanups across the tree, but the
    above are the major pieces"

    Pull power management and ACPI updates from Rafael Wysocki:
    "Quite a new features are included this time.

    First off, the Collaborative Processor Performance Control interface
    (version 2) defined by ACPI will now be supported on ARM64 along with
    a cpufreq frontend for CPU performance scaling.

    Second, ACPI gets a new infrastructure for the early probing of IRQ
    chips and clock sources (along the lines of the existing similar
    mechanism for DT).

    Next, the ACPI core and the generic device properties API will now
    support a recently introduced hierarchical properties extension of the
    _DSD (Device Specific Data) ACPI device configuration object. If the
    ACPI platform firmware uses that extension to organize device
    properties in a hierarchical way, the kernel will automatically handle
    it and make those properties available to device drivers via the
    generic device properties API.

    It also will be possible to build the ACPICA's AML interpreter
    debugger into the kernel now and use that to diagnose AML-related
    problems more efficiently. In the future, this should make it
    possible to single-step AML execution and do similar things.
    Interesting stuff, although somewhat experimental at this point.

    Finally, the PM core gets a new mechanism that can be used by device
    drivers to distinguish between suspend-to-RAM (based on platform
    firmware support) and suspend-to-idle (or other variants of system
    suspend the platform firmware is not involved in) and possibly
    optimize their device suspend/resume handling accordingly.

    In addition to that, some existing features are re-organized quite
    substantially.

    First, the ACPI-based handling of PCI host bridges on x86 and ia64 is
    unified and the common code goes into the ACPI core (so as to reduce
    code duplication and eliminate non-essential differences between the
    two architectures in that area).

    Second, the Operating Performance Points (OPP) framework is
    reorganized to make the code easier to find and follow.

    Next, the cpufreq core's sysfs interface is reorganized to get rid of
    the "primary CPU" concept for configurations in which the same
    performance scaling settings are shared between multiple CPUs.

    Finally, some interfaces that aren't necessary any more are dropped
    from the generic power domains framework.

    On top of the above we have some minor extensions, cleanups and bug
    fixes in multiple places, as usual.

    Specifics:

    - ACPICA update to upstream revision 20150930 (Bob Moore, Lv Zheng).

    The most significant change is to allow the AML debugger to be
    built into the kernel. On top of that there is an update related
    to the NFIT table (the ACPI persistent memory interface) and a few
    fixes and cleanups.

    - ACPI CPPC2 (Collaborative Processor Performance Control v2) support
    along with a cpufreq frontend (Ashwin Chaugule).

    This can only be enabled on ARM64 at this point.

    - New ACPI infrastructure for the early probing of IRQ chips and
    clock sources (Marc Zyngier).

    - Support for a new hierarchical properties extension of the ACPI
    _DSD (Device Specific Data) device configuration object allowing
    the kernel to handle hierarchical properties (provided by the
    platform firmware this way) automatically and make them available
    to device drivers via the generic device properties interface
    (Rafael Wysocki).

    - Generic device properties API extension to obtain an index of
    certain string value in an array of strings, along the lines of
    of_property_match_string(), but working for all of the supported
    firmware node types, and support for the "dma-names" device
    property based on it (Mika Westerberg).

    - ACPI core fix to parse the MADT (Multiple APIC Description Table)
    entries in the order expected by platform firmware (and mandated by
    the specification) to avoid confusion on systems with more than 255
    logical CPUs (Lukasz Anaczkowski).

    - Consolidation of the ACPI-based handling of PCI host bridges on x86
    and ia64 (Jiang Liu).

    - ACPI core fixes to ensure that the correct IRQ number is used to
    represent the SCI (System Control Interrupt) in the cases when it
    has been re-mapped (Chen Yu).

    - New ACPI backlight quirk for Lenovo IdeaPad S405 (Hans de Goede).

    - ACPI EC driver fixes (Lv Zheng).

    - Assorted ACPI fixes and cleanups (Dan Carpenter, Insu Yun, Jiri
    Kosina, Rami Rosen, Rasmus Villemoes).

    - New mechanism in the PM core allowing drivers to check if the
    platform firmware is going to be involved in the upcoming system
    suspend or if it has been involved in the suspend the system is
    resuming from at the moment (Rafael Wysocki).

    This should allow drivers to optimize their suspend/resume handling
    in some cases and the changes include a couple of users of it (the
    i8042 input driver, PCI PM).

    - PCI PM fix to prevent runtime-suspended devices with PME enabled
    from being resumed during system suspend even if they aren't
    configured to wake up the system from sleep (Rafael Wysocki).

    - New mechanism to report the number of a wakeup IRQ that woke up the
    system from sleep last time (Alexandra Yates).

    - Removal of unused interfaces from the generic power domains
    framework and fixes related to latency measurements in that code
    (Ulf Hansson, Daniel Lezcano).

    - cpufreq core sysfs interface rework to make it handle CPUs that
    share performance scaling settings (represented by a common cpufreq
    policy object) more symmetrically (Viresh Kumar).

    This should help to simplify the CPU offline/online handling among
    other things.

    - cpufreq core fixes and cleanups (Viresh Kumar).

    - intel_pstate fixes related to the Turbo Activation Ratio (TAR)
    mechanism on client platforms which causes the turbo P-states range
    to vary depending on platform firmware settings (Srinivas
    Pandruvada).

    - intel_pstate sysfs interface fix (Prarit Bhargava).

    - Assorted cpufreq driver (imx, tegra20, powernv, integrator) fixes
    and cleanups (Bai Ping, Bartlomiej Zolnierkiewicz, Shilpasri G
    Bhat, Luis de Bethencourt).

    - cpuidle mvebu driver cleanups (Russell King).

    - OPP (Operating Performance Points) framework code reorganization to
    make it more maintainable (Viresh Kumar).

    - Intel Broxton support for the RAPL (Running Average Power Limits)
    power capping driver (Amy Wiles).

    - Assorted power management code fixes and cleanups (Dan Carpenter,
    Geert Uytterhoeven, Geliang Tang, Luis de Bethencourt, Rasmus
    Villemoes)"
