  • 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.

  • 03d14a553   [ARM] 4690/1: PXA: fix CKEN corruption in PXA27x AC97 cold reset code ... Browse Code »

    Fix CKEN register corruption in the PXA27x cold reset code
    located in sound/arm/pxa27x-ac97.c. The problem has been
    introduced with a pxa_set_cken() function change in linux 2.6.23.
    This patch is based on patch 4527/1 that fixes the same problem in
    the ASoC PXA-AC97 driver. Additionally a definition for the CKEN
    index value is added and applied to both PXA AC97 drivers.

  • 632155e65   potential parse error in ifdef ... Browse Code »

    I have made a tool to parse the kernel that does not pre-process the
    source. That means that my parser tries to parse all the code, including
    code in the #else branch or code that is not often compiled because the
    driver is not very used (or not used at all). So, my parser sometimes
    reports parse error not originally detected by gcc. Here is my (first)
    patch.

  • 7053acbd7   [ARM] 4304/1: removes the unnecessary bit number from CKENnn_XXXX ... Browse Code »

    This patch removes the unnecessary bit number from CKENnn_XXXX
    definitions for PXA, so that

    CKEN0_PWM0 --> CKEN_PWM0
    CKEN1_PWM1 --> CKEN_PWM1
    ...
    CKEN24_CAMERA --> CKEN_CAMERA

    The reasons for the change of these defitions are:

    1. they do not scale - they are currently valid for pxa2xx, but
    definitely not valid for pxa3xx, e.g., pxa3xx has bit 3 for camera
    instead of bit 24

    2. they are unnecessary - the peripheral name within the definition
    has already announced its usage, we don't need those bit numbers
    to know which peripheral we are going to enable/disable clock for

    3. they are inconvenient - think about this: a driver programmer
    for pxa has to remember which bit in the CKEN register to turn
    on/off

    Another change in the patch is to make the definitions equal to its
    clock bit index, so that

    #define CKEN_CAMERA (24)

    instead of

    #define CKEN_CAMERA (1 << 24)

    this change, however, will add a run-time bit shift operation in
    pxa_set_cken(), but the benefit of this change is that it scales
    when bit index exceeds 32, e.g., pxa3xx has two registers CKENA
    and CKENB, totally 64 bit for this, suppose CAMERA clock enabling
    bit is CKENB:10, one can simply define CKEN_CAMERA to be (32 + 10)
    and so that pxa_set_cken() need minimum change to adapt to that.

  • 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.

    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.

  • 9480e307c   [PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacks ... Browse Code »

    In PM v1, all devices were called at SUSPEND_DISABLE level. Then
    all devices were called at SUSPEND_SAVE_STATE level, and finally
    SUSPEND_POWER_DOWN level. However, with PM v2, to maintain
    compatibility for platform devices, I arranged for the PM v2
    suspend/resume callbacks to call the old PM v1 suspend/resume
    callbacks three times with each level in order so that existing
    drivers continued to work.

    Since this is obsolete infrastructure which is no longer necessary,
    we can remove it. Here's an (untested) patch to do exactly that.
