  • Remove the __devinitconst to fix the section mismatch.

    WARNING: drivers/uio/built-in.o(.data+0x2e8): Section mismatch in
    reference from the variable uio_pdrv_genirq to the variable
    .devinit.rodata:uio_of_genirq_match
    The variable uio_pdrv_genirq references
    the variable __devinitconst uio_of_genirq_match
    If the reference is valid then annotate the
    variable with __init* or __refdata (see linux/init.h) or name the
    variable:
    *driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one,
    *_console

  • Adding OF binding to genirq.
    Version string is setup to the "devicetree".

    Compatible string is not setup for now but you can add your
    custom compatible string to uio_of_genirq_match structure.

    For example with "vendor,device" compatible string:
    static const struct of_device_id __devinitconst uio_of_genirq_match[] = {
    { .compatible = "vendor,device", },
    { /* empty for now */ },
    };

  • …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.

  • This patch modifies the uio_pdrv_genirq driver to support
    Runtime PM. The power management implementation simply
    runtime resumes the device at open() time and runtime
    suspends it at release() time. The user space driver is
    responsible for re-initializing the hardware after open().

  • I can't think of a reason why the driver prevents people from setting any
    custom bits in their platform device, but I can think of some reasons for
    allowing custom flags. Like setting the IRQF_TRIGGER_... bits.

  • This is V3 of uio_pdrv_genirq.c, a platform driver for UIO with
    generic IRQ handling code. This driver is very similar to the regular
    UIO platform driver, but is only suitable for devices that are
    connected to the interrupt controller using unique interrupt lines.

    The uio_pdrv_genirq driver includes generic interrupt handling code
    which disables the serviced interrupt in the interrupt controller
    and makes the user space driver responsible for acknowledging the
    interrupt in the device and reenabling the interrupt in the interrupt
    controller.

    Shared interrupts are not supported since the in-kernel interrupt
    handler will disable the interrupt line in the interrupt controller,
    and in a shared interrupt configuration this will stop other devices
    from delivering interrupts.
