    Move the power of 2 check on frequencies down into individual rtc drivers

    This is to allow for non power of 2 real time clock periodic interrupts
    such as those on the pxa27x to be found in the new pxa27x-rtc driver

  • 773be7ee9   rtc: rtc-s3c: update IRQ handling ... Browse Code »

    The rtc-s3c.c driver has been using its own ioctl() handling to deal with
    alarm and periodic interrupts to handle what should now be done with the
    rtc core code.

    Change to using the .irq_set_freq and .irq_set_state driver entries and
    remove the .ioctl handling.

  • 7ca1d488f   rtc: suspend()/resume() restores system clock ... Browse Code »

    RTC class suspend/resume support, re-initializing the system clock on resume
    from the clock used to initialize it at boot time.

    - The reinit-on-resume is hooked to the existing RTC_HCTOSYS config
    option, on the grounds that a clock good enough for init must also
    be good enough for re-init.

    - Inlining a version of the code used by ARM, to save and restore the
    delta between a selected RTC and the current system wall-clock time.

    - Removes calls to that ARM code from AT91, OMAP1, and S3C RTCs. This
    means that systems using those RTCs across suspend/resume will likely
    want to change their kernel configs to enable RTC_HCTOSYS.

    If HCTOSYS isn't using a second RTC (with battery?), this changes the
    system's initial date from Jan 1970 to the epoch this hardware uses:
    1998 for AT91, 2000 for OMAP1 (assuming no split power mode), etc.

    This goes on top of the patch series removing "struct class_device" usage
    from the RTC framework. That's all needed for class suspend()/resume().

    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.

    This is a renamed and tested version of the previous S3C24XX RTC class
    driver.

    The driver has been renamed from the original s3c2410-rtc, which is now too
    narrow for the range of devices supported.

    The rtc-s3c has been chosen as there is the distinct possibility of this
    driver being carried forward into newer Samsung SoC silicon.
