  • 0f91349b8   usb: gadget: convert all users to the new udc infrastructure ... Browse Code »

    peripheral drivers are using usb_add_gadget()/usb_del_gadget() to
    register/unregister to the udc-core.

    The udc-core will take the first available gadget driver and attach
    function driver which is calling usb_gadget_register_driver(). This is
    the same behaviour we have right now.

    Only dummy_hcd was tested, the others were compiled tested.

  • b0fca50f5   usb gadget: don't save bind callback in struct usb_gadget_driver ... Browse Code »

    To accomplish this the function to register a gadget driver takes the bind
    function as a second argument. To make things clearer rename the function
    to resemble platform_driver_probe.

    This fixes many section mismatches like

    WARNING: drivers/usb/gadget/g_printer.o(.data+0xc): Section mismatch in
    reference from the variable printer_driver to the function
    .init.text:printer_bind()
    The variable printer_driver references
    the function __init printer_bind()

    All callers are fixed.

  • 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.

  • 2c59b0b70   usb: m66592-udc platform data on_chip support ... Browse Code »

    Convert the m66592-udc driver to use the on_chip flag
    from platform data to enable on chip behaviour instead
    of relying on CONFIG_SUPERH_BUILT_IN_M66592 ugliness.

    This makes the code cleaner and also allows us to support
    both external and internal m66592 with the same kernel.

    It also makes the Kconfig part more future proof since
    we with this patch can add support for new processors
    with on-chip m66592 without modifying the Kconfig.

    The patch adds a m66592 header file for platform data
    and ties in platform data to the existing m66592 devices.

  • 4048e5ca2   usb: m66592-udc buffer management update ... Browse Code »

    This patch updates the m66592-udc buffer management code.

    Use fixed buffers for bulk and isochronous pipes, also make
    sure to handle the isochronous-as-bulk case. With fixed buffers
    there is no need to keep track of used buffers with bi_bufnum.

    Also, this fixes a potential buffer offset problem where the
    base offset incorrectly varies with the number of pipes used.

    With this patch applied it is possible to use m66592-udc for
    both Ethernet and Serial using CONFIG_USB_CDC_COMPOSITE.
