  • 981bcead3   ALSA: trident - pause s/pdif output ... Browse Code »

    Stop the S/PDIF DMA engine and output when the device is told to pause.
    It will keep on looping the current buffer contents if this isn't done.

  • 9004acc70   [ALSA] Remove sound/driver.h ... Browse 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.

    Remove sequencer instrument layer from the tree.
    This mechanism hasn't been used much with the actual devices. The only
    reasonable user was OPL3 loader, and now it was rewritten to use hwdep
    instead. So, let's remove the rest of rotten codes.

  • 30b35399c   [ALSA] Various fixes for suspend/resume of ALSA PCI drivers ... Browse Code »

    - Check the return value of pci_enable_device() and request_irq()
    in the suspend. If any error occurs there, disable the device
    using snd_card_disconnect().
    - Call pci_set_power_state() properly with pci_choose_state().
    - Fix the order to call pci_set_power_state().
    - Removed obsolete house-made PM codes in some drivers.

  • 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.

    Description: Fix-up sleeping in sound/pci. These changes fall under the
    following two categories:

    1) Replace schedule_timeout() with msleep() to guarantee the
    task delays as expected. This also involved replacing/removing
    custom sleep functions.
    2) Do not assume jiffies will only increment by one if you
    request a 1 jiffy sleep, i.e. use time_after/time_before in
    while loops.

  • 77933d727   [PATCH] clean up inline static vs static inline ... Browse Code »

    `gcc -W' likes to complain if the static keyword is not at the beginning of
    the declaration. This patch fixes all remaining occurrences of "inline
    static" up with "static inline" in the entire kernel tree (140 occurrences in
    47 files).

    While making this change I came across a few lines with trailing whitespace
    that I also fixed up, I have also added or removed a blank line or two here
    and there, but there are no functional changes in the patch.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
