  • 6ea741a13   powerpc/ps3: irq: Remove IRQF_DISABLED ... Browse Code »

    Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled],
    We run all interrupt handlers with interrupts disabled
    and we even check and yell when an interrupt handler
    returns with interrupts enabled (see commit [b738a50a:
    genirq: Warn when handler enables interrupts]).

    So now this flag is a NOOP and can be removed.

  • 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.

  • bc00351ed   powerpc/ps3: Workaround for flash memory I/O error ... Browse Code »

    A workaround for flash memory I/O errors when the PS3 internal
    hard disk has not been formatted for OtherOS use.

    This error condition mainly effects 'Live CD' users who have not
    formatted the PS3's internal hard disk for OtherOS.

    Fixes errors similar to these when using the ps3-flash-util
    or ps3-boot-game-os programs:

    ps3flash read failed 0x2050000
    os_area_header_read: read error: os_area_header: Input/output error
    main:627: os_area_read_hp error.
    ERROR: can't change boot flag

    We just fix up the reference parameters as the others are dealt with by

    This removes warnings like this:

    Also, these:

    Compiling with CONFIG_SMP = n and CONFIG_PS3_LPM != n gives this error:

    drivers/ps3/ps3-lpm.c:838: error: implicit declaration of function 'get_hard_smp_processor_id'

    This fixes it. We have to include rather than
    because the UP definition of get_hard_smp_processor_id()
    is in , and only includes if
    CONFIG_SMP = y.

    This stray down would cause a permanent sleep which doesn't seem correct.
    The other uses of this semaphore appear fairly mutex like it's even
    initialized with init_MUTEX() .. So here a patch for removing this one
