  • 4277f2c46   video: convert drivers/video/* to use module_platform_driver() ... Browse Code »

    This patch converts the drivers in drivers/video/* to use the
    module_platform_driver() macro which makes the code smaller and a bit
    simpler.

  • 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.

  • c2e13037e   platform-drivers: move probe to .devinit.text in drivers/video ... Browse Code »

    A pointer to a probe callback is passed to the core via
    platform_driver_register and so the function must not disappear when the
    .init sections are discarded. Otherwise (if also having HOTPLUG=y)
    unbinding and binding a device to the driver via sysfs will result in an
    oops as does a device being registered late.

    An alternative to this patch is using platform_driver_probe instead of
    platform_driver_register plus removing the pointer to the probe function
    from the struct platform_driver.

  • 537a1bf05   fbdev: add mutex for fb_mmap locking ... Browse Code »
    43

    Add a mutex to avoid a circular locking problem between the mm layer
    semaphore and fbdev ioctl mutex through the fb_mmap() call.

    Also, add mutex to all places where smem_start and smem_len fields change
    so the mutex inside the fb_mmap() is actually used. Changing of these
    fields before calling the framebuffer_register() are not mutexed.

    This is 2.6.31 material. It removes one lockdep (fb_mmap() and
    register_framebuffer()) but there is still another one (fb_release() and
    register_framebuffer()). It also cleans up handling of the smem_start and
    smem_len fields used by mutexed section of the fb_mmap().

  • c465e05a0   [PATCH] fbcon/fbdev: Move softcursor out of fbdev to fbcon ... Browse Code »

    According to Jon Smirl, filling in the field fb_cursor with soft_cursor for
    drivers that do not support hardware cursors is redundant. The soft_cursor
    function is usable by all drivers because it is just a wrapper around
    fb_imageblit. And because soft_cursor is an fbcon-specific hook, the file is
    moved to the console directory.

    Thus, drivers that do not support hardware cursors can leave the fb_cursor
    field blank. For drivers that do, they can fill up this field with their own
    version.

    The end result is a smaller code size. And if the framebuffer console is not
    loaded, module/kernel size is also reduced because the soft_cursor module will
    also not be loaded.

  • 9480e307c   [PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacks ... Browse Code »

    In PM v1, all devices were called at SUSPEND_DISABLE level. Then
    all devices were called at SUSPEND_SAVE_STATE level, and finally
    SUSPEND_POWER_DOWN level. However, with PM v2, to maintain
    compatibility for platform devices, I arranged for the PM v2
    suspend/resume callbacks to call the old PM v1 suspend/resume
    callbacks three times with each level in order so that existing
    drivers continued to work.

    Since this is obsolete infrastructure which is no longer necessary,
    we can remove it. Here's an (untested) patch to do exactly that.

  • aac51f09d   [PATCH] w100fb: Rewrite for platform independence ... Browse Code »

    The code w100fb was based on was horribly Sharp SL-C7x0 specific and there
    was little else that could be done as I had no access to anything else with
    a w100 in it. There is no real documentation about this chipset available.

    Ian Molton has access to other platforms with the w100 (Toshiba e-series)
    and so between us, we've improved w100fb and made it platform independent.
    Ian Molton also added support for the very similar w3220 and w3200
    chipsets.

    There are a lot of changes here and it nearly amounts to a rewrite of the
    driver but it has been extensively tested and is being used in preference
    to the original driver in the Zaurus community. I'd therefore like to
    update the mainline code to reflect this.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
