  • 0c4eae665   rtc: convert drivers/rtc/* to use module_platform_driver() ... Browse Code »

    This patch converts the drivers in drivers/rtc/* to use the
    module_platform_driver() macro which makes the code smaller and a bit
    simpler.

  • 416f0e805   RTC: sa1100: Update the sa1100 RTC driver. ... Browse Code »

    Since PIE interrupts are now emulated, this patch removes the previous
    code that used the hardware counters.

    The removal of read_callback() also fixes a wrong user space behaviour
    of this driver, which was not returning the right value to read().

    With the generic RTC rework, the UIE mode irqs are handled
    in the generic layer, and only hardware specific ioctls
    get passed down to the rtc driver layer.

    So this patch removes the UIE mode ioctl handling in the rtc
    driver layer, which never get used.

  • 16380c153   RTC: Convert rtc drivers to use the alarm_irq_enable method ... Browse Code »

    Some rtc drivers use the ioctl method instead of the alarm_irq_enable
    method for enabling alarm interupts. With the new virtualized RTC
    rework, its important for drivers to use the alarm_irq_enable instead.

    This patch converts the drivers that use the AIE ioctl method to
    use the alarm_irq_enable method. Other ioctl cmds are left untouched.

    I have not been able to test or even compile most of these drivers.
    Any help to make sure this change is correct would be appreciated!

    The remaining registers are separated into:

    -
    -
    -

    and then we can remove pxa-regs.h completely. Instead of #include this
    file, let's:

    1. include the specific with care (if that's absolutely
    necessary)

    2. define the registers in the driver, make cleanly defined API to expose
    the register access to external with sufficient reason

    a constant on PXA when multiple processors and platforms are
    selected, change TIMER_FREQ in rtc-sa1100.c into a variable.

    Since the code to decide the clock tick rate is re-used from

    Remove some more references to dev->power.power_state. That field is overdue
    for removal, but we can't do that while it's still referenced in the kernel.
    The only reason to update it was to make the /sys/devices/.../power/state
    files (now removed) work better.

  • 32b49da46   [PATCH] rtc-sa1100 rtc_wklarm.enabled bugfixes ... Browse Code »

    Some rtc-sa1100 bugfixes:

    - The read_alarm() method reports the rtc_wkalrm.enabled field properly.
    This patch is already in the handhelds.org tree.

    - And the set_alarm() method now handles that flag correctly, rather than
    making mismatched {en,dis}able_irq_wake() calls, which trigger runtime
    warning messages. (Those calls are best made in suspend/resume methods.)

    Note that while this SA1100/PXA RTC is fully capable of waking those ARM
    processors from sleep states, that mechanism isn't properly supported on
    either processor family, or in this driver. Some boards have board-specific
    PM glue providing partial workarounds for the weak generic PM support.

    Fix a glitch in the procfs dumping of whether the alarm IRQ is enabled: use
    the traditional name (from drivers/char/rtc.c and many other places) of
    "alarm_IRQ", not "alrm_wakeup" (which didn't even match the efirtc code, which
    originated that reporting API).

    Also, update a few of the RTC drivers to stop providing that duplicate status,
    and/or to expose it properly when reporting the alarm state. We really don't
    want every RTC driver doing their own thing here...

  • 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.

    locking init cleanups:

    - convert " = SPIN_LOCK_UNLOCKED" to spin_lock_init() or DEFINE_SPINLOCK()
    - convert rwlocks in a similar manner

    this patch was generated automatically.

    Motivation:

    - cleanliness
    - lockdep needs control of lock initialization, which the open-coded
    variants do not give
    - it's also useful for -rt and for lock debugging in general
