  • …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.

  • Add accelerated bitblt functions to s1d13xxx based video chipsets, more
    specificly functions copyarea and fillrect.

    It has only been tested and activated for 13506 chipsets but is expected
    to work for the majority of s1d13xxx based chips. This patch also cleans
    up the driver with respect of whitespaces and other formatting issues. We
    update the current status comments.

  • The s1d13xxx chip provides two values of identification value: the
    Production id (e.g 13506/13505/13806..) and a revision number 0,1,2,3).
    Together these can help us to differentiate between similiar setups.

    This patch adds the proper way of grabbing both those values and save them
    for future reference (in order to decide what functions a card supports,
    e.g acceleration).

    We also move away from the concept of all s1d13xxx = s1d13806 when we
    really support alot more.

  • The Epson s1d13xxx hardware is common in many handhelds, but our driver is
    currently locked to a single chip revision. This patch adds an array of
    known to work revisions (which can be extended).

  • 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.

  • 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.

  • This patch is for supporting Epson s1d13xxx framebuffer device for m32r. #
    Sorry, a little bigger.

    The Epson s1d13806 is already supported by 2.6.12 kernel, and its driver is
    placed as drivers/video/s1d13xxxfb.c.

    For the m32r, a header file include/asm-m32r/s1d13806.h was prepared for
    several m32r target platforms. It was originally generated by an Epson
    tool S1D13806CFG.EXE, and modified manually for the m32r platforms.

  • s1d13xxxfb_remove() is referenced from s1d13xxxfb_probe(), which is marked
    __devinit(). So s1d13xxxfb_remove() cannot be marked __devexit.

    Does this all make sense? Clearly the __devexit section will still be in
    core when the __devinit code is run, if the driver was loaded as a module.

    But I suppose that if the driver is statically linked, the __devexit section
    might be dropped early in boot. Still, we wouldn't drop __devexit prior to
    initcall completion, at which point the __devinit code has all been run
    anyway.

    verdict: this code was legal and made sense. Is this a generic problem, or an
    arm-specific problem?

  • 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!
