  • 43dcd13b9   fbdev: fix parsing of standard timings ... Browse Code »

    The standard timings parses uses 1:1 dimensions when the ratio in the
    EDID data is 0. However, for EDID 1.3 and later the dimensions are 16:10
    when the ratio is 0.

    Pass the version and revision numbers to get_std_timing() which can then
    make the right decision about dimensions.

  • 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.

  • 3730793d4   fbmon: work around compiler bug in gcc-2.4.2 ... Browse Code »

    There's some odd bug in gcc-4.2 where it miscompiles a simple loop whent
    he loop counter is of type 'unsigned char' and it should count to 128.

    The compiler will incorrectly decide that a trivial loop like this:

    unsigned char i, ...

    for (i = 0; i < 128; i++) {
    ..

    is endless, and will compile it to a single instruction that just
    branches to itself.

    This was triggered by the addition of '-fno-strict-overflow', and we
    could play games with compiler versions and go back to '-fwrapv'
    instead, but the trivial way to avoid it is to just make the loop
    induction variable be an 'int' instead.

    Thanks to Krzysztof Oledzki for reporting and testing and to Troy Moure
    for digging through assembler differences and finding it.

    The width and height members of fb_var_screeninfo are __u32. The code
    initializes them to -1 which seems wrong, and 0 seems like an equally good
    default value.

  • a8f340e39   [PATCH] vt: Remove VT-specific declarations and definitions from tty.h ... Browse Code »

    MAX_NR_CONSOLES, fg_console, want_console and last_console are more of a
    function of the VT layer than the TTY one. Moving these to vt.h and vt_kern.h
    allows all of the framebuffer and VT console drivers to remove their
    dependency on tty.h.

  • 300768314   [PATCH] fbdev: More accurate sync range extrapolation ... Browse Code »

    The EDID block should specify the display's operating limits (vertical and
    horizontal sync ranges, and maximum dot clock). If not given by the EDID
    block, the ranges are extrapolated from the modelist. However, the
    computation used is only a rough approximation, and the resulting values may
    not reflect the actual capability of the display. This problem is frequently
    encountered when the EDID block has a single entry, the single mode entry will
    fail validation.

    To prevent this, calculate the values based on the same method used in
    fb_validate_mode().

    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!
