  • 14e04fb34   ACPI: Schedule /proc/acpi/event for removal ... Browse Code »

    Schedule /proc/acpi/event for removal in 6 months.

    Re-name acpi_bus_generate_event() to acpi_bus_generate_proc_event()
    to make sure there is no confusion that it is for /proc/acpi/event only.

    Add CONFIG_ACPI_PROC_EVENT to allow removal of /proc/acpi/event.
    There is no functional change if CONFIG_ACPI_PROC_EVENT=y

  • 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

  • 91a690295   sysfs: add parameter "struct bin_attribute *" in .read/.write methods for sysfs binary attributes ... Browse Code »

    Well, first of all, I don't want to change so many files either.

    What I do:
    Adding a new parameter "struct bin_attribute *" in the
    .read/.write methods for the sysfs binary attributes.

    In fact, only the four lines change in fs/sysfs/bin.c and
    include/linux/sysfs.h do the real work.
    But I have to update all the files that use binary attributes
    to make them compatible with the new .read and .write methods.
    I'm not sure if I missed any. :(

    Why I do this:
    For a sysfs attribute, we can get a pointer pointing to the
    struct attribute in the .show/.store method,
    while we can't do this for the binary attributes.
    I don't know why this is different, but this does make it not
    so handy to use the binary attributes as the regular ones.
    So I think this patch is reasonable. :)

    Who benefits from it:
    The patch that exposes ACPI tables in sysfs
    requires such an improvement.
    All the table binary attributes share the same .read method.
    Parameter "struct bin_attribute *" is used to get
    the table signature and instance number which are used to
    distinguish different ACPI table binary attributes.

    Without this parameter, we need to offer different .read methods
    for different ACPI table binary attributes.
    This is impossible as there are various ACPI tables on different
    platforms, and we don't know what they are until they are loaded.

  • 7b595756e   sysfs: kill unnecessary attribute->owner ... Browse Code »

    sysfs is now completely out of driver/module lifetime game. After
    deletion, a sysfs node doesn't access anything outside sysfs proper,
    so there's no reason to hold onto the attribute owners. Note that
    often the wrong modules were accounted for as owners leading to
    accessing removed modules.

    This patch kills now unnecessary attribute->owner. Note that with
    this change, userland holding a sysfs node does not prevent the
    backing module from being unloaded.

    For more info regarding lifetime rule cleanup, please read the
    following message.

  • 0bbd6424c   PCI: hotplug: acpiphp: avoid acpiphp "cannot get bridge info" PCI hotplug failure ... Browse Code »

    On some systems, the ACPI bus check event can reference a bridge that is
    higher in the ACPI hierarchy than the bridge immediately above the
    hotplug PCI slot into which an adapter was just inserted. The current
    'acpiphp' code expects the bus check event to reference the bridge
    immediately above the slot that received the adapter so the hotplug
    operation can fail on these systems with the message "acpiphp_glue:
    cannot get bridge info". This change fixes the problem by
    re-enumerating all slots that lie below the bridge referenced by the bus
    check event, including those slots that may be located under lower level
    PCI-to-PCI bridge(s).

    On systems where the optional _PS3 ACPI object is not implemented
    acpiphp fails to power off the slot. This is happening because the
    current code does not attempt to remove power using the _EJ0 ACPI
    object. This patch restores the _EJ0 evaluation attempt which was
    apparently inadvertently removed from the power-off sequence when the
    _EJ0 evaluation code was relocated from power_off_slot() to
    acpiphp_eject_slot().

  • 44c10138f   PCI: Change all drivers to use pci_device->revision ... Browse Code »
    88

    Instead of all drivers reading pci config space to get the revision
    ID, they can now use the pci_device->revision member.

    This exposes some issues where drivers where reading a word or a dword
    for the revision number, and adding useless error-handling around the
    read. Some drivers even just read it for no purpose of all.

    In devices where the revision ID is being copied over and used in what
    appears to be the equivalent of hotpath, I have left the copy code
    and the cached copy as not to influence the driver's performance.

    Compile tested with make all{yes,mod}config on x86_64 and i386.

  • 3d5134ee8   [POWERPC] Rewrite IO allocation & mapping on powerpc64 ... Browse Code »

    This rewrites pretty much from scratch the handling of MMIO and PIO
    space allocations on powerpc64. The main goals are:

    - Get rid of imalloc and use more common code where possible
    - Simplify the current mess so that PIO space is allocated and
    mapped in a single place for PCI bridges
    - Handle allocation constraints of PIO for all bridges including
    hot plugged ones within the 2GB space reserved for IO ports,
    so that devices on hotplugged busses will now work with drivers
    that assume IO ports fit in an int.
    - Cleanup and separate tracking of the ISA space in the reserved
    low 64K of IO space. No ISA -> Nothing mapped there.

    I booted a cell blade with IDE on PIO and MMIO and a dual G5 so
    far, that's it :-)

    With this patch, all allocations are done using the code in
    mm/vmalloc.c, though we use the low level __get_vm_area with
    explicit start/stop constraints in order to manage separate
    areas for vmalloc/vmap, ioremap, and PCI IOs.

    This greatly simplifies a lot of things, as you can see in the
    diffstat of that patch :-)

    A new pair of functions pcibios_map/unmap_io_space() now replace
    all of the previous code that used to manipulate PCI IOs space.
    The allocation is done at mapping time, which is now called from
    scan_phb's, just before the devices are probed (instead of after,
    which is by itself a bug fix). The only other caller is the PCI
    hotplug code for hot adding PCI-PCI bridges (slots).

    imalloc is gone, as is the "sub-allocation" thing, but I do beleive
    that hotplug should still work in the sense that the space allocation
    is always done by the PHB, but if you unmap a child bus of this PHB
    (which seems to be possible), then the code should properly tear
    down all the HPTE mappings for that area of the PHB allocated IO space.

    I now always reserve the first 64K of IO space for the bridge with
    the ISA bus on it. I have moved the code for tracking ISA in a separate
    file which should also make it smarter if we ever are capable of
    hot unplugging or re-plugging an ISA bridge.

    This should have a side effect on platforms like powermac where VGA IOs
    will no longer work. This is done on purpose though as they would have
    worked semi-randomly before. The idea at this point is to isolate drivers
    that might need to access those and fix them by providing a proper
    function to obtain an offset to the legacy IOs of a given bus.

  • e8edc6e03   Detach sched.h from mm.h ... Browse Code »

    First thing mm.h does is including sched.h solely for can_do_mlock() inline
    function which has "current" dereference inside. By dealing with can_do_mlock()
    mm.h can be detached from sched.h which is good. See below, why.

    This patch
    a) removes unconditional inclusion of sched.h from mm.h
    b) makes can_do_mlock() normal function in mm/mlock.c
    c) exports can_do_mlock() to not break compilation
    d) adds sched.h inclusions back to files that were getting it indirectly.
    e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were
    getting them indirectly

    Net result is:
    a) mm.h users would get less code to open, read, preprocess, parse, ... if
    they don't need sched.h
    b) sched.h stops being dependency for significant number of files:
    on x86_64 allmodconfig touching sched.h results in recompile of 4083 files,
    after patch it's only 3744 (-8.3%).

    Cross-compile tested on

    all arm defconfigs, all mips defconfigs, all powerpc defconfigs,
    alpha alpha-up
    arm
    i386 i386-up i386-defconfig i386-allnoconfig
