  • 3514141ae   powerpc/pmac: Fix DMA ops for MacIO devices ... Browse Code »

    The macio_dev's created to map devices inside the MacIO ASICs
    don't have proper dma_ops. This causes crashes on some machines
    since the SCSI code calls dma_map_* on our behalf using the
    device we hang from.

    This fixes it by copying the parent PCI device dma_ops into
    the macio_dev when creating it.

  • 6e99e4582   [PATCH] powerpc: fix trigger handling in the new irq code ... Browse Code »

    This patch slightly reworks the new irq code to fix a small design error. I
    removed the passing of the trigger to the map() calls entirely, it was not a
    good idea to have one call do two different things. It also fixes a couple of
    corner cases.

    Mapping a linux virtual irq to a physical irq now does only that. Setting the
    trigger is a different action which has a different call.

    The main changes are:

    - I no longer call host->ops->map() for an already mapped irq, I just return
    the virtual number that was already mapped. It was called before to give an
    opportunity to change the trigger, but that was causing issues as that could
    happen while the interrupt was in use by a device, and because of the
    trigger change, map would potentially muck around with things in a racy way.
    That was causing much burden on a given's controller implementation of
    map() to get it right. This is much simpler now. map() is only called on
    the initial mapping of an irq, meaning that you know that this irq is _not_
    being used. You can initialize the hardware if you want (though you don't
    have to).

    - Controllers that can handle different type of triggers (level/edge/etc...)
    now implement the standard irq_chip->set_type() call as defined by the
    generic code. That means that you can use the standard set_irq_type() to
    configure an irq line manually if you wish or (though I don't like that
    interface), pass explicit trigger flags to request_irq() as defined by the
    generic kernel interfaces. Also, using those interfaces guarantees that
    your controller set_type callback is called with the descriptor lock held,
    thus providing locking against activity on the same interrupt (including
    mask/unmask/etc...) automatically. A result is that, for example, MPIC's
    own map() implementation calls irq_set_type(NONE) to configure the hardware
    to the default triggers.

    - To allow the above, the irq_map array entry for the new mapped interrupt
    is now set before map() callback is called for the controller.

    - The irq_create_of_mapping() (also used by irq_of_parse_and_map()) function
    for mapping interrupts from the device-tree now also call the separate
    set_irq_type(), and only does so if there is a change in the trigger type.

    - While I was at it, I changed pci_read_irq_line() (which is the helper I
    would expect most archs to use in their pcibios_fixup() to get the PCI
    interrupt routing from the device tree) to also handle a fallback when the
    DT mapping fails consisting of reading the PCI_INTERRUPT_PIN to know wether
    the device has an interrupt at all, and the the PCI_INTERRUPT_LINE to get an
    interrupt number from the device. That number is then mapped using the
    default controller, and the trigger is set to level low. That default
    behaviour works for several platforms that don't have a proper interrupt
    tree like Pegasos. If it doesn't work for your platform, then either
    provide a proper interrupt tree from the firmware so that fallback isn't
    needed, or don't call pci_read_irq_line()

    - Add back a bit that got dropped by my main rework patch for properly
    clearing pending IPIs on pSeries when using a kexec

  • 0ebfff149   [POWERPC] Add new interrupt mapping core and change platforms to use it ... Browse Code »

    This adds the new irq remapper core and removes the old one. Because
    there are some fundamental conflicts with the old code, like the value
    of NO_IRQ which I'm now setting to 0 (as per discussions with Linus),
    etc..., this commit also changes the relevant platform and driver code
    over to use the new remapper (so as not to cause difficulties later
    in bisecting).

    This patch removes the old pre-parsing of the open firmware interrupt
    tree along with all the bogus assumptions it made to try to renumber
    interrupts according to the platform. This is all to be handled by the
    new code now.

    For the pSeries XICS interrupt controller, a single remapper host is
    created for the whole machine regardless of how many interrupt
    presentation and source controllers are found, and it's set to match
    any device node that isn't a 8259. That works fine on pSeries and
    avoids having to deal with some of the complexities of split source
    controllers vs. presentation controllers in the pSeries device trees.

    The powerpc i8259 PIC driver now always requests the legacy interrupt
    range. It also has the feature of being able to match any device node
    (including NULL) if passed no device node as an input. That will help
    porting over platforms with broken device-trees like Pegasos who don't
    have a proper interrupt tree.

  • d63fb6c55   [PATCH] powermac: Fix some 64b resource damage ... Browse Code »

    The 64 bits resource patches did a bit of damage on PowerMac causing a
    buffer overflow in macio_asic and a warning in a sound driver. The
    former is fixed by reverting the sprintf of the bus_id to %08x as it was
    before. The bus_id used for macio devices is always a 32 bits value
    (macio always sits in 32 bits space) and since it's exposed to userland,
    the format of the string shouldn't be changed like that anyway. The
    second by using the proper type for printk.

  • 4e57b6817   [PATCH] fix missing includes ... Browse Code »

    I recently picked up my older work to remove unnecessary #includes of
    sched.h, starting from a patch by Dave Jones to not include sched.h
    from module.h. This reduces the number of indirect includes of sched.h
    by ~300. Another ~400 pointless direct includes can be removed after
    this disentangling (patch to follow later).
    However, quite a few indirect includes need to be fixed up for this.

    In order to feed the patches through -mm with as little disturbance as
    possible, I've split out the fixes I accumulated up to now (complete for
    i386 and x86_64, more archs to follow later) and post them before the real
    patch. This way this large part of the patch is kept simple with only
    adding #includes, and all hunks are independent of each other. So if any
    hunk rejects or gets in the way of other patches, just drop it. My scripts
    will pick it up again in the next round.

  • 184f6eb8c   [PATCH] openfirmware: implement hotplug for macio devices ... Browse Code »

    This adds the hotplug routine for generating hotplug events when devices
    are seen on the macio bus. It uses the attributed created by the sysfs
    nodes to generate the hotplug environment vars for userspace.

    Since the characters allowed inside the 'compatible' field are NUL
    terminated, they are exported as individual OF_COMPATIBLE_# variables,
    with OF_COMPATIBLE_N maintaining a count of how many there are.

    In order for hotplug to work with macio devices, patches to
    module-init-tools and hotplug must be applied. Those patches are
