    The sound drivers and the pnpbios core test for current->root != NULL. This
    test seems to be unnecessary since we always have rootfs mounted before
    initializing the drivers.

  • e70515dd5   [ALSA] snd-powermac: handle dead DMA transfers ... Browse Code »

    This patch provides the snd-powermac sound driver with the ability to handle
    dead DMA transfers. If a dead DMA transfer is detected, the driver now sets
    up a new DMA transfer to continue with the sound output at the point where the
    old transfer died.
    This dead DMA transfer handling has become necessary with recent kernels on
    certain G4 PowerMacs. Please refer to the following URLs for more information:
    https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3126
    https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/87652
    http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=436723
    The patch is based on the dead DMA transfer handling code from the old dmasound
    driver which can be found in the file sound/oss/dmasound/dmasound_awacs.c in
    the Linux source code.

    This header file exists only for some hacks to adapt alsa-driver
    tree. It's useless for building in the kernel. Let's move a few
    lines in it to sound/core.h and remove it.
    With this patch, sound/driver.h isn't removed but has just a single
    compile warning to include it. This should be really killed in
    future.

  • 41e904dee   [POWERPC] Fix snd-powermac refcounting bugs ... Browse Code »

    The old snd-powermac driver has some serious refcounting issues when
    initialisation fails, which is the case on all new machines with
    a layout-id since those are handled by the new snd-aoa driver.

    Some of those bugs seem to have been under the radar for some time
    (like double pci_dev_put), but one was actually added in 2.6.22 with
    Stephen attempt at teaching refcounting to the driver which didn't
    do it at all.

    This patch fixes both, thus removing all sort of kref errors that
    would happen if that driver gets loaded on a G5 machine or a recent
    PowerBook due to OF nodes left around with a 0 refcount.

  • 7d12e780e   IRQ: Maintain regs pointer globally rather than passing to IRQ handlers ... Browse Code »

    Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
    of passing regs around manually through all ~1800 interrupt handlers in the
    Linux kernel.

    The regs pointer is used in few places, but it potentially costs both stack
    space and code to pass it around. On the FRV arch, removing the regs parameter
    from all the genirq function results in a 20% speed up of the IRQ exit path
    (ie: from leaving timer_interrupt() to leaving do_IRQ()).

    Where appropriate, an arch may override the generic storage facility and do
    something different with the variable. On FRV, for instance, the address is
    maintained in GR28 at all times inside the kernel as part of general exception
    handling.

    Having looked over the code, it appears that the parameter may be handed down
    through up to twenty or so layers of functions. Consider a USB character
    device attached to a USB hub, attached to a USB controller that posts its
    interrupts through a cascaded auxiliary interrupt controller. A character
    device driver may want to pass regs to the sysrq handler through the input
    layer which adds another few layers of parameter passing.

    I've build this code with allyesconfig for x86_64 and i386. I've runtested the
    main part of the code on FRV and i386, though I can't test most of the drivers.
    I've also done partial conversion for powerpc and MIPS - these at least compile
    with minimal configurations.

    This will affect all archs. Mostly the changes should be relatively easy.
    Take do_IRQ(), store the regs pointer at the beginning, saving the old one:

    struct pt_regs *old_regs = set_irq_regs(regs);

    And put the old one back at the end:

    set_irq_regs(old_regs);

    Don't pass regs through to generic_handle_irq() or __do_IRQ().

    In timer_interrupt(), this sort of change will be necessary:

    - update_process_times(user_mode(regs));
    - profile_tick(CPU_PROFILING, regs);
    + update_process_times(user_mode(get_irq_regs()));
    + profile_tick(CPU_PROFILING);

    I'd like to move update_process_times()'s use of get_irq_regs() into itself,
    except that i386, alone of the archs, uses something other than user_mode().

    Some notes on the interrupt handling in the drivers:

    (*) input_dev() is now gone entirely. The regs pointer is no longer stored in
    the input_dev struct.

    (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does
    something different depending on whether it's been supplied with a regs
    pointer or not.

    (*) Various IRQ handler function pointers have been moved to type
    irq_handler_t.

  • 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.

    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.

  • e8222502e   [PATCH] powerpc: Kill _machine and hard-coded platform numbers ... Browse Code »

    This removes statically assigned platform numbers and reworks the
    powerpc platform probe code to use a better mechanism. With this,
    board support files can simply declare a new machine type with a
    macro, and implement a probe() function that uses the flattened
    device-tree to detect if they apply for a given machine.

    We now have a machine_is() macro that replaces the comparisons of
    _machine with the various PLATFORM_* constants. This commit also
    changes various drivers to use the new macro instead of looking at
    _machine.
