    snd_cs5535audio_mixer() is only called by __devinit snd_cs5535audio_probe(),
    so the mixer function can also be __devinit.

  • 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.

  • 4ea241639   [ALSA] cs5535audio: drop unused bus master stuff ... Browse Code »

    We really only care about the first two bus masters (playback and capture).
    There's no need to have unused BM code lying around, so let's get rid of it.
    If for some reason we trigger an IRQ for some BM that we're not using.. well,
    that warrants spitting out an error message (imo).

    According to 6.3.2.7 of the cs5535/cs5536 data sheets, the ACC_BM[x]_CMD
    registers are only 8 bits wide. This driver treats them as 32 bits wide,
    and also has bits in the wrong place. Simple fix to the definitions.

  • 222fa0b0d   [ALSA] cs5535audio: fix PRD register save/restore power management race ... Browse Code »

    In the suspend path, we currently save the PRD registers and then disable DMA.
    This is racy; the sound hardware might update the PRD register as it finishes
    processing some DMA pages between when we've saved the PRD registers and
    when DMA actually gets disabled. Furthermore, we actively check whether or
    not DMA is enabled before saving PRD registers; there's no reason to do that,
    as the PRD registers should not update when we twiddle the ACC_BM[x]_CMD
    register(s). Worst case, we save the PRD registers twice; even powering
    down the ACC shouldn't mess with the PRD registers (according to the 5536
    data sheet, section 5.3.7.4, power-down procedure). This patch reworks
    all that to first disable DMA, and then save PRD registers.

  • 7abcacb09   [ALSA] cs5535audio: correctly set dma->substream ... Browse Code »

    We're never actually setting dma->substream to the current substream; that
    means the dma->substream checks that we do in the suspend/resume path
    are never satisfied, and the PRD registers are never correctly managed. This
    changes it so that we set the substream when constructing the specific
    bus master DMA, and unsetting it when we tear down the BM's DMA.

    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.

    Modules: CS5535 driver

    The 10 ms sleeps while waiting for AC'97 codec register reads/writes to
    complete are excessive given the maxmium time is one AC'97 frame (~21 us).

    With AC'97 codecs with integrated touchscreens (like the UCB1400) this
    improves the interactive performance of the touchscreen.
