  • 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.

  • Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled],
    We run all interrupt handlers with interrupts disabled
    and we even check and yell when an interrupt handler
    returns with interrupts enabled (see commit [b738a50a:
    genirq: Warn when handler enables interrupts]).

    So now this flag is a NOOP and can be removed.

  • The semantics of snd_mpu401_uart_new()'s interrupt parameters are
    somewhat counterintuitive: To prevent the function from allocating its
    own interrupt, either the irq number must be invalid, or the irq_flags
    parameter must be zero. At the same time, the irq parameter being
    invalid specifies that the mpu401 code has to work without an interrupt
    allocated by the caller. This implies that, if there is an interrupt
    and it is allocated by the caller, the irq parameter must be set to
    a valid-looking number which then isn't actually used.

    With the removal of IRQF_DISABLED, zero becomes a valid irq_flags value,
    which forces us to handle the parameters differently.

    This patch introduces a new flag MPU401_INFO_IRQ_HOOK for when the
    device interrupt is handled by the caller, and makes the allocation of
    the interrupt to depend only on the irq parameter. As suggested by
    Takashi, the irq_flags parameter was dropped because, when used, it had
    the constant value IRQF_DISABLED.

  • Smatch complains that if (dev == SNDRV_CARDS) we're one past the end of
    the array. That's unlikely to happen in real life, I suppose.

    Also smatch complains about "strcpy(card->shortname, pcm->name);"
    The "pcm->name" buffer is 80 characters and "card->shortname" is 32
    characters. If you follow the call paths it turns out we never actually
    use more than 16 characters so it's not a problem. But anyway, let's
    make it easy for people auditing this in the future.

  • The ESS ES968 chip is nothing more then a PnP companion
    for a non-PnP audio chip. It was paired with non-PnP ESS' chips:
    ES688 and ES1688. The ESS' audio chips are handled by the es1688
    driver in native mode. The PnP cards are handled by the ES968
    driver in SB compatible mode.

    Move the ES968 chip handling to the es1688 driver so the driver
    can handle both PnP and non-PnP cards. The es968 is removed.

    Also, a new PnP id is added for the card I acquired (the change
    was tested on this card).

  • To avoid confusion in control names for the standard analog PC Beep generator
    using a small Internal PC Speaker, rename all related "PC Speaker" and "PC
    Beep" controls to "Beep" only. This name is more universal and can be also
    used on more platforms without confusion.

    Introduce also "Internal Speaker" in ControlNames.txt for systems with
    full-featured build-in internal speaker.

  • 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.

  • 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.

  • 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!
