  • e428c6a27   RTC: Clean out UIE icotl implementations ... Browse Code »

    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.

    With the generic rtc code now emulating PIE mode irqs via an
    hrtimer, no one calls the rtc_class_ops->irq_set_freq call.

    This patch removes the hook and deletes the driver functions
    if no one else calls them.

  • 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!

    request_mem_region() will call kzalloc to allocate memory for struct resource.
    release_resource() unregisters the resource but does not free the allocated
    memory, thus use release_mem_region() instead to fix the memory leak.

  • 5a0e3ad6a   include cleanup: Update gfp.h and slab.h includes to prepare for breaking implic… ... Browse Code »

    …it slab.h inclusion from percpu.h

    percpu.h is included by sched.h and module.h and thus ends up being
    included when building most .c files. percpu.h includes slab.h which
    in turn includes gfp.h making everything defined by the two files
    universally available and complicating inclusion dependencies.

    percpu.h -> slab.h dependency is about to be removed. Prepare for
    this change by updating users of gfp and slab facilities include those
    headers directly instead of assuming availability. As this conversion
    needs to touch large number of source files, the following script is
    used as the basis of conversion.

    http://userweb.kernel.org/~tj/misc/slabh-sweep.py

    The script does the followings.

    * Scan files for gfp and slab usages and update includes such that
    only the necessary includes are there. ie. if only gfp is used,
    gfp.h, if slab is used, slab.h.

    * When the script inserts a new include, it looks at the include
    blocks and try to put the new include such that its order conforms
    to its surrounding. It's put in the include block which contains
    core kernel includes, in the same order that the rest are ordered -
    alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
    doesn't seem to be any matching order.

    * If the script can't find a place to put a new include (mostly
    because the file doesn't have fitting include block), it prints out
    an error message indicating which .h file needs to be added to the
    file.

    The conversion was done in the following steps.

    1. The initial automatic conversion of all .c files updated slightly
    over 4000 files, deleting around 700 includes and adding ~480 gfp.h
    and ~3000 slab.h inclusions. The script emitted errors for ~400
    files.

    2. Each error was manually checked. Some didn't need the inclusion,
    some needed manual addition while adding it to implementation .h or
    embedding .c file was more appropriate for others. This step added
    inclusions to around 150 files.

    3. The script was run again and the output was compared to the edits
    from #2 to make sure no file was left behind.

    4. Several build tests were done and a couple of problems were fixed.
    e.g. lib/decompress_*.c used malloc/free() wrappers around slab
    APIs requiring slab.h to be added manually.

    5. The script was run on all .h files but without automatically
    editing them as sprinkling gfp.h and slab.h inclusions around .h
    files could easily lead to inclusion dependency hell. Most gfp.h
    inclusion directives were ignored as stuff from gfp.h was usually
    wildly available and often used in preprocessor macros. Each
    slab.h inclusion directive was examined and added manually as
    necessary.

    6. percpu.h was updated not to include slab.h.

    7. Build test were done on the following configurations and failures
    were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
    distributed build env didn't work with gcov compiles) and a few
    more options had to be turned off depending on archs to make things
    build (like ipr on powerpc/64 which failed due to missing writeq).

    * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
    * powerpc and powerpc64 SMP allmodconfig
    * sparc and sparc64 SMP allmodconfig
    * ia64 SMP allmodconfig
    * s390 SMP allmodconfig
    * alpha SMP allmodconfig
    * um on x86_64 SMP allmodconfig

    8. percpu.h modifications were reverted so that it could be applied as
    a separate patch and serve as bisection point.

    Given the fact that I had only a couple of failures from tests on step
    6, I'm fairly confident about the coverage of this conversion patch.
    If there is a breakage, it's likely to be something in one of the arch
    headers which should be easily discoverable easily on most builds of
    the specific arch.

  • 1043bf5c9   rtc: rtc-sh: Fix up oops in early periodic freq assignment. ... Browse Code »

    With the reordered init order, the rtc device is not registered until
    later, while sh_rtc_irq_set_freq() was attempting to assign ->irq_freq
    directly, resulting in an oops. This is handled by the upper layers for
    us, so just kill off the problematic dereference completely.

    Add support for single IRQ hardware to the sh-rtc driver.

    This is useful for processors with limited interrupt masking
    support such as sh7750 and sh7780. With this patch in place we
    can add logic to the intc code that merges all RTC vectors into
    a single linux interrupt with proper masking/unmasking support.

    Specify a single IRQ in the platform data to use this new shared
    IRQ feature. Separate Periodic/Carry/Alarm IRQs are still supported.

  • 2fac6674d   rtc: bunch of drivers: fix 'no irq' case handing ... Browse Code »

    This patch fixes a bunch of irq checking misuses. Most drivers were
    getting irq via platform_get_irq(), which returns -ENXIO or r->start.

    rtc-cmos.c is special. It is using PNP and platform bindings. Hopefully
    nobody is using PNP IRQ 0 for RTC. So the changes should be safe.

    rtc-sh.c is using platform_get_irq, but was storing a result into an
    unsigned type, then was checking for < 0. This is fixed now.

  • 743e6a504   rtc: file close() consistently disables repeating irqs ... Browse Code »

    Make the rtc framework consistent about disabling 1/second update IRQs
    that may have been activated through the /dev interface, when that /dev
    file is closed. (It may have closed because of coredump, etc.) This was
    previously done only for emulated update IRQs ... now, do it always.

    Also comment the current policy: repeating IRQs (periodic, update) that
    userspace enabled will be cleanly disabled, but alarms are left alone.
    Such repeating IRQs are a constant and pointless system load.

    Update some RTC drivers to remove now-needless release() methods. Most
    such methods just enforce that policy. The others all seem to be buggy,
    and mistreat in-kernel clients of periodic or alarm IRQs.

    All SH-4 parts have a 4-digit year, while the SH-3 parts typically

    however opted to extend it to 4-digit and still look and act like
    an SH-3 RTC in all other ways.

    This adds a capability flag (RTC_CAP_4_DIGIT_YEAR) that these
    corner-case CPU subtypes can set in their platform data and cleans
    up some of the ifdef mess in the driver as a result.
