  • 7b7b8a2c9   kernel/: fix repeated words in comments ... Browse Code »

    Fix multiple occurrences of duplicated words in kernel/.

    Fix one typo/spello on the same line as a duplicate word. Change one
    instance of "the the" to "that the". Otherwise just drop one of the
    repeated words.

    Pull power management updates from Rafael Wysocki:
    "These rework the collection of cpufreq statistics to allow it to take
    place if fast frequency switching is enabled in the governor, rework
    the frequency invariance handling in the cpufreq core and drivers, add
    new hardware support to a couple of cpufreq drivers, fix a number of
    assorted issues and clean up the code all over.

    Specifics:

    - Rework cpufreq statistics collection to allow it to take place when
    fast frequency switching is enabled in the governor (Viresh Kumar).

    - Make the cpufreq core set the frequency scale on behalf of the
    driver and update several cpufreq drivers accordingly (Ionela
    Voinescu, Valentin Schneider).

    - Add new hardware support to the STI and qcom cpufreq drivers and
    improve them (Alain Volmat, Manivannan Sadhasivam).

    - Fix multiple assorted issues in cpufreq drivers (Jon Hunter,
    Krzysztof Kozlowski, Matthias Kaehlcke, Pali Rohár, Stephan
    Gerhold, Viresh Kumar).

    - Fix several assorted issues in the operating performance points
    (OPP) framework (Stephan Gerhold, Viresh Kumar).

    - Allow devfreq drivers to fetch devfreq instances by DT enumeration
    instead of using explicit phandles and modify the devfreq core code
    to support driver-specific devfreq DT bindings (Leonard Crestez,
    Chanwoo Choi).

    - Improve initial hardware resetting in the tegra30 devfreq driver
    and clean up the tegra cpuidle driver (Dmitry Osipenko).

    - Update the cpuidle core to collect state entry rejection statistics
    and expose them via sysfs (Lina Iyer).

    - Improve the ACPI _CST code handling diagnostics (Chen Yu).

    - Update the PSCI cpuidle driver to allow the PM domain
    initialization to occur in the OSI mode as well as in the PC mode
    (Ulf Hansson).

    - Rework the generic power domains (genpd) core code to allow domain
    power off transition to be aborted in the absence of the "power
    off" domain callback (Ulf Hansson).

    - Fix two suspend-to-idle issues in the ACPI EC driver (Rafael
    Wysocki).

    - Fix the handling of timer_expires in the PM-runtime framework on
    32-bit systems and the handling of device links in it (Grygorii
    Strashko, Xiang Chen).

    - Add IO requests batching support to the hibernate image saving and
    reading code and drop a bogus get_gendisk() from there (Xiaoyi
    Chen, Christoph Hellwig).

    - Allow PCIe ports to be put into the D3cold power state if they are
    power-manageable via ACPI (Lukas Wunner).

    - Add missing header file include to a power capping driver (Pujin
    Shi).

    - Clean up the qcom-cpr AVS driver a bit (Liu Shixin).

    - Kevin Hilman steps down as designated reviwer of adaptive voltage
    scaling (AVS) drivers (Kevin Hilman)"

  • 55c4478a8   PM: hibernate: Batch hibernate and resume IO requests ... Browse Code »

    Hibernate and resume process submits individual IO requests for each page
    of the data, so use blk_plug to improve the batching of these requests.

    Testing this change with hibernate and resumes consistently shows merging
    of the IO requests and more than an order of magnitude improvement in
    hibernate and resume speed is observed.

    One hibernate and resume cycle for 16GB RAM out of 32GB in use takes
    around 21 minutes before the change, and 1 minutes after the change on
    a system with limited storage IOPS.

  • 70d932985   notifier: Fix broken error handling pattern ... Browse Code »

    The current notifiers have the following error handling pattern all
    over the place:

    int err, nr;

    err = __foo_notifier_call_chain(&chain, val_up, v, -1, &nr);
    if (err & NOTIFIER_STOP_MASK)
    __foo_notifier_call_chain(&chain, val_down, v, nr-1, NULL)

    And aside from the endless repetition thereof, it is broken. Consider
    blocking notifiers; both calls take and drop the rwsem, this means
    that the notifier list can change in between the two calls, making @nr
    meaningless.

    Fix this by replacing all the __foo_notifier_call_chain() functions
    with foo_notifier_call_chain_robust() that embeds the above pattern,
    but ensures it is inside a single lock region.

    Note: I switched atomic_notifier_call_chain_robust() to use
    the spinlock, since RCU cannot provide the guarantee
    required for the recovery.

    Note: software_resume() error handling was broken afaict.

  • d42f3245c   mm: memcg: convert vmstat slab counters to bytes ... Browse Code »

    In order to prepare for per-object slab memory accounting, convert
    NR_SLAB_RECLAIMABLE and NR_SLAB_UNRECLAIMABLE vmstat items to bytes.

    To make it obvious, rename them to NR_SLAB_RECLAIMABLE_B and
    NR_SLAB_UNRECLAIMABLE_B (similar to NR_KERNEL_STACK_KB).

    Internally global and per-node counters are stored in pages, however memcg
    and lruvec counters are stored in bytes. This scheme may look weird, but
    only for now. As soon as slab pages will be shared between multiple
    cgroups, global and node counters will reflect the total number of slab
    pages. However memcg and lruvec counters will be used for per-memcg slab
    memory tracking, which will take separate kernel objects in the account.
    Keeping global and node counters in pages helps to avoid additional
    overhead.

    The size of slab memory shouldn't exceed 4Gb on 32-bit machines, so it
    will fit into atomic_long_t we use for vmstats.

  • 48001ea50   PM, libnvdimm: Add runtime firmware activation support ... Browse Code »

    Abstract platform specific mechanics for nvdimm firmware activation
    behind a handful of generic ops. At the bus level ->activate_state()
    indicates the unified state (idle, busy, armed) of all DIMMs on the bus,
    and ->capability() indicates the system state expectations for activate.
    At the DIMM level ->activate_state() indicates the per-DIMM state,
    ->activate_result() indicates the outcome of the last activation
    attempt, and ->arm() attempts to transition the DIMM from 'idle' to
    'armed'.

    A new hibernate_quiet_exec() facility is added to support firmware
    activation in an OS defined system quiesce state. It leverages the fact
    that the hibernate-freeze state wants to assert that a memory
    hibernation snapshot can be taken. This is in contrast to a platform
    firmware defined quiesce state that may forcefully quiet the memory
    controller independent of whether an individual device-driver properly
    supports hibernate-freeze.

    The libnvdimm sysfs interface is extended to support detection of a
    firmware activate capability. The mechanism supports enumeration and
    triggering of firmware activate, optionally in the
    hibernate_quiet_exec() context.

    Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
    '---help---'"), the number of '---help---' has been gradually
    decreasing, but there are still more than 2400 instances.

    This commit finishes the conversion. While I touched the lines,
    I also fixed the indentation.

    There are a variety of indentation styles found.

    a) 4 spaces + '---help---'
    b) 7 spaces + '---help---'
    c) 8 spaces + '---help---'
    d) 1 space + 1 tab + '---help---'
    e) 1 tab + '---help---' (correct indentation)
    f) 1 tab + 1 space + '---help---'
    g) 1 tab + 2 spaces + '---help---'

    In order to convert all of them to 1 tab + 'help', I ran the
    following commend:

    $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'
