  • 903b0eb39   ALSA: sound/arm: Fix build failure caused by missing struct aaci definition ... Browse Code »

    This patch fixes a build failure introduced by the patch
    ALSA: AACI: factor common hw_params logic into aaci_pcm_hw_params [1]
    by adding/moving the aaci struct to the right position.

    The patch mentioned above merged common source parts into one function,
    but unfortunately left out the aaci struct and consequently caused a
    build failure e.g. for arm versatile_config [2]

  • 29a4f2d31   ALSA: aaci: ARM1176 aaci-pl041 AC97 register read timeout ... Browse Code »

    After a reboot on an ARM1176 which amounts to a softreset, it has been
    noted that the ALSA driver does not get registered and the probe fails
    with the error "aaci-pl041 fpga:04: ac97 read back fail". In the process
    of reading from a register the SL1TxBusy bit is set indicating that the
    transceiver is busy and remains so until the default timeout occurs.
    Set the Power down register 0x26 to an arbitrary value as specified in
    the PL041 manual (page: 3-18) so that AACISL1TX/AACISL2TX registers take
    their default state.

  • dc890c2dc   [ARM] 5544/1: Trust PrimeCell resource sizes ... Browse Code »

    I found the PrimeCell/AMBA Bus drivers distrusting the resource
    passed in as part of the struct amba_device abstraction. This
    patch removes all hard coded resource sizes found in the PrimeCell
    drivers and move the responsibility of this definition back to
    the platform/board device definition, which already exist and
    appear to be correct for all in-tree users of these drivers.
    We do this using the resource_size() inline function which was
    also replicated in the only driver using the resource size, so
    that has been changed too. The KMI_SIZE was left in kmi.h in case
    someone likes it. Test-compiled against Versatile and Integrator
    defconfigs, seems to work but I don't posess these boards and
    cannot test them.

  • 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.

  • 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.

  • f27f218cd   [ARM] 3290/1: Fix the FIFO size detection ... Browse Code »

    Patch from Catalin Marinas

    AACI reports TX FIFO full after the first write to it if the AC97 is not
    enabled. This patch enables the AC97 probing before the check for the TX
    FIFO size. The patch also adds a warning if the TX FIFO size is not
    multiple of 16.
