  • a67ff6a54   ALSA: module_param: make bool parameters really bool ... Browse Code »

    module_param(bool) used to counter-intuitively take an int. In
    fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
    trick.

    It's time to remove the int/unsigned int option. For this version
    it'll simply give a warning, but it'll break next kernel version.

  • 934c2b6d0   ALSA: use KBUILD_MODNAME for request_irq argument in sound/pci/* ... Browse Code »

    The name argument of request_irq() appears in /proc/interrupts, and
    it's quite ugly when the name entry contains a space or special letters.
    In general, it's simpler and more readable when the module name appears
    there, so let's replace all entries with KBUILD_MODNAME.

  • 3733e424c   ALSA: Use KBUILD_MODNAME for pci_driver.name entries ... Browse Code »

    The convention for pci_driver.name entry in kernel drivers seem to be
    the module name or equivalent ones. But, so far, almost all PCI sound
    drivers use more verbose name like "ABC Xyz (12)", and these are fairly
    confusing when appearing as a file name.

    This patch converts the all pci_driver.name entries in sound/pci/* to
    use KBUILD_MODNAME for more unified appearance.

  • 2f5ad54ea   pci: use pci_ioremap_bar() in sound/ ... Browse Code »

    Use the newly introduced pci_ioremap_bar() function in sound/.
    pci_ioremap_bar() just takes a pci device and a bar number, with the goal
    of making it really hard to get wrong, while also having a central place
    to stick sanity checks.

  • f000fd809   [ALSA] Fix synchronize_irq() bugs, redundancies ... Browse Code »

    free_irq() calls synchronize_irq() for you, so there is no need for
    drivers to manually do the same thing (again). Thus, calls where
    sync-irq immediately precedes free-irq can be simplified.

    However, during this audit several bugs were noticed, where free-irq is
    preceded by a "irq >= 0" check... but the sync-irq call is not covered
    by the same check.

    So, where sync-irq could not be eliminated completely, the missing check
    was added.

  • 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.

    Fix IRQ flags for PCI devices.
    The shared IRQs for PCI devices shouldn't be allocated with
    IRQF_DISABLED. Also, when MSI is enabled, IRQF_SHARED shouldn't
    be used.
    The patch removes unnecessary cast in request_irq and free_irq,
    too.

  • 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.
