  • eb9d0fe40   PCI ACPI: Rework PCI handling of wake-up ... Browse Code »

    * Introduce function acpi_pm_device_sleep_wake() for enabling and
    disabling the system wake-up capability of devices that are power
    manageable by ACPI.

    * Introduce function acpi_bus_can_wakeup() allowing other (dependent)
    subsystems to check if ACPI is able to enable the system wake-up
    capability of given device.

    * Introduce callback .sleep_wake() in struct pci_platform_pm_ops and
    for the ACPI PCI 'driver' make it use acpi_pm_device_sleep_wake().

    * Introduce callback .can_wakeup() in struct pci_platform_pm_ops and
    for the ACPI 'driver' make it use acpi_bus_can_wakeup().

    * Move the PME# handlig code out of pci_enable_wake() and split it
    into two functions, pci_pme_capable() and pci_pme_active(),
    allowing the caller to check if given device is capable of
    generating PME# from given power state and to enable/disable the
    device's PME# functionality, respectively.

    * Modify pci_enable_wake() to use the new ACPI callbacks and the new
    PME#-related functions.

    * Drop the generic .platform_enable_wakeup() callback that is not
    used any more.

    * Introduce device_set_wakeup_capable() that will set the
    power.can_wakeup flag of given device.

    * Rework PCI device PM initialization so that, if given device is
    capable of generating wake-up events, either natively through the
    PME# mechanism, or with the help of the platform, its
    power.can_wakeup flag is set and its power.should_wakeup flag is
    unset as appropriate.

    * Make ACPI set the power.can_wakeup flag for devices found to be
    wake-up capable by it.

    * Make the ACPI wake-up code enable/disable GPEs for devices that
    have the wakeup.flags.prepared flag set (which means that their
    wake-up power has been enabled).

  • 7752d5cfe   x86: validate against acpi motherboard resources ... Browse Code »

    This path adds validation of the MMCONFIG table against the ACPI reserved
    motherboard resources. If the MMCONFIG table is found to be reserved in
    ACPI, we don't bother checking the E820 table. The PCI Express firmware
    spec apparently tells BIOS developers that reservation in ACPI is required
    and E820 reservation is optional, so checking against ACPI first makes
    sense. Many BIOSes don't reserve the MMCONFIG region in E820 even though
    it is perfectly functional, the existing check needlessly disables MMCONFIG
    in these cases.

    In order to do this, MMCONFIG setup has been split into two phases. If PCI
    configuration type 1 is not available then MMCONFIG is enabled early as
    before. Otherwise, it is enabled later after the ACPI interpreter is
    enabled, since we need to be able to execute control methods in order to
    check the ACPI reserved resources. Presently this is just triggered off
    the end of ACPI interpreter initialization.

    There are a few other behavioral changes here:

    - Validate all MMCONFIG configurations provided, not just the first one.

    - Validate the entire required length of each configuration according to
    the provided ending bus number is reserved, not just the minimum required
    allocation.

    - Validate that the area is reserved even if we read it from the chipset
    directly and not from the MCFG table. This catches the case where the
    BIOS didn't set the location properly in the chipset and has mapped it
    over other things it shouldn't have.

    This also cleans up the MMCONFIG initialization functions so that they
    simply do nothing if MMCONFIG is not compiled in.

    Based on an original patch by Rajesh Shah from Intel.

  • 6697c0529   x86: fix sparse warnings in acpi/bus.c ... Browse Code »

    Add function definition and extern variables to asm-x86/acpi.h.

    All of these are used in bus.c in ifdef(CONFIG_X86) sections, so are
    only added to the x86 include headers. boot.c already includes acpi.h
    so no changes are needed there.

    Fixes the following:
    arch/x86/kernel/acpi/boot.c:83:4: warning: symbol 'acpi_sci_flags' was not declared. Should it be static?
    arch/x86/kernel/acpi/boot.c:84:5: warning: symbol 'acpi_sci_override_gsi' was not declared. Should it be static?

  • 9f9adecd2   PM: ACPI and APM must not be enabled at the same time ... Browse Code »

    ACPI and APM used "pm_active" to guarantee that
    they would not be simultaneously active.

    But pm_active was recently moved under CONFIG_PM_LEGACY,
    so that without CONFIG_PM_LEGACY, pm_active became a NOP --
    allowing ACPI and APM to both be simultaneously enabled.
    This caused unpredictable results, including boot hangs.

    Further, the code under CONFIG_PM_LEGACY is scheduled
    for removal.

    So replace pm_active with pm_flags.
    pm_flags depends only on CONFIG_PM,
    which is present for both CONFIG_APM and CONFIG_ACPI.

  • 5e32132be   ide: hook ACPI _PSx method to IDE power on/off ... Browse Code »

    ACPI spec defines the sequence of IDE power on/off:
    Powering down:

    Power down drive (calls _PS3 method and turns off power planes).
    Powering up:
    Power up drive (calls _PS0 method if present and turns on power planes).
    Call _STM passing info from _GTM (possibly modified), with ID data from
    each drive.
    Initialize the channel.
    May modify the results of _GTF.
    For each drive:
    Call _GTF.
    Execute task file (possibly modified).
    This patch adds the missed _PS0/_PS3 methods call.

  • 962ce8ca0   ACPI: don't duplicate input events on netlink ... Browse Code »

    The previous events patch added a netlink event for every
    user of the legacy /proc/acpi/event interface.

    However, some users of /proc/acpi/event are really input events,
    and they already report their events via the input layer.

    Introduce a new interface, acpi_bus_generate_netlink_event(),
    which is explicitly called by devices that want to repoprt
    events via netlink. This allows the input-like events
    to opt-out of generating netlink events. In summary:

    events that are sent via netlink:
    ac/battery/sbs
    thermal
    processor
    thinkpad_acpi dock/bay

    events that are sent via input layer:
    button
    video hotkey
    thinkpad_acpi hotkey
    asus_acpi/asus-laptop hotkey
    sonypi/sonylaptop

    2. Add ACPI device in device tree.

    File "eject" for every device that has _EJ0 method is moved from
    /sys/firmware to /sys/devices.
    Operation on this file is exactly the same as before.
    i.e. echo 1 to "eject" will cause hot removal of this device.
    Corresponding changes should be made in userspace for hot removal.
