  • 41d9c644f   memstick: change to new flag variable ... Browse Code »

    The EXTRA_CFLAGS assignment in memstick/Makefile was not accomplishing
    anything because this flag only has effect on sources at the same level
    as the makefile (i.e., per directory). Since both core/ and host/ rely
    on MEMSTICK_DEBUG, the subdir-ccflags-y variant seems to be the
    appropriate choice.

  • 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.

  • 8e82f8c34   memstick: fix MSProHG 8-bit interface mode support ... Browse Code »

    - 8-bit interface mode never worked properly. The only adapter I have
    which supports the 8b mode (the Jmicron) had some problems with its
    clock wiring and they discovered it only now. We also discovered that
    ProHG media is more sensitive to the ordering of initialization
    commands.

    - Make the driver fall back to highest supported mode instead of always
    falling back to serial. The driver will attempt the switch to 8b mode
    for any new MSPro card, but not all of them support it. Previously,
    these new cards ended up in serial mode, which is not the best idea
    (they work fine with 4b, after all).

    - Edit some macros for better conformance to Sony documentation

    Instead of using a separate thread to pump requests from block layer queue
    to memstick, do so inline, utilizing the callback design of the memstick.

  • b77899985   memstick: allow "set_param" method to return an error code ... Browse Code »

    Some controllers (Jmicron, for instance) can report temporal failure
    condition during power-on. It is desirable to account for this using a
    return value of "set_param" device method. The return value can also be
    handy to distinguish between supported and unsupported device parameters
    in run time.

    Sony MemoryStick cards are used in many products manufactured by Sony.
    They are available both as storage and as IO expansion cards. Currently,
    only MemoryStick Pro storage cards are supported via TI FlashMedia
    MemoryStick interface.
