  • 66cde97da   s3fb: fix Virge/VX ... Browse Code »

    Add memory size detection for Virge/VX and small delay in mode setting (same
    as in X.org driver) to fix blank screen problem.

    Also adjust DTPC position to fix garbled screen in some modes (tested that
    this adjustment does not break other cards - at least Trio32, Trio64V+,
    Trio64V2/DX, Virge, Virge/DX).

    Tested on ELSA Winner 2000AVI/3D.

  • 86c0f043a   s3fb: add DDC support ... Browse Code »

    Add I2C support for the DDC bus and also default mode initialization by
    reading monitor EDID to the s3fb driver.

    Tested on Trio64V+ (2 cards), Trio64V2/DX, Virge (3 cards),
    Virge/DX (3 cards), Virge/GX2, Trio3D/2X (4 cards), Trio3D.

    Will probably not work on Trio32 - my 2 cards have DDC support in BIOS that
    looks different from the other cards but the DDC pins on the VGA connector
    are not connected.

  • 94e948e6e   s3fb: fix Virge/GX2 ... Browse Code »

    Fix Virge/GX2 support in s3fb:
    - fix IDs: 86C357 is GX2, 86C359 is GX2+, 86C356 probably does not exist
    - add memory size detection
    - drive it the same way as Trio3D/2X

    The original IDs most likely came from S3 website which claims that:
    - 356 is Virge/GX2 with ID=8A10, driver included in Windows 2K, XP
    - 357 is Virge/GX2+ with ID=8A11, driver included in Windows ME
    - 359 is Virge/GX2+ with ID=8A12, driver included in Windows ME
    but:
    - google search for 86C356 only reveals references to Trio3D (probably
    because of a typo - Trio3D is 86C365)
    - my card is clearly marked as 86C357, Virge/GX2 and has ID=8A10
    - there is no driver for IDs 8A11 and 8A12 in Windows ME
    - there is a driver for ID 8A10 in Windows ME that says it's GX2 (357)

    Tested with #9 Reality 334 (86C357 Virge/GX2, ID=0x8A10).

  • ac751efa6   console: rename acquire/release_console_sem() to console_lock/unlock() ... Browse Code »

    The -rt patches change the console_semaphore to console_mutex. As a
    result, a quite large chunk of the patches changes all
    acquire/release_console_sem() to acquire/release_console_mutex()

    This commit makes things use more neutral function names which dont make
    implications about the underlying lock.

    The only real change is the return value of console_trylock which is
    inverted from try_acquire_console_sem()

    This patch also paves the way to switching console_sem from a semaphore to
    a mutex.

  • 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.

    causes a null-pointer deref because "info->dev is NULL, info was just

    This patch adds check if selected pixclock is valid (is in the PLL range).

    Previously, if the pixclock could not be set, the new mode resolution was set
    but pixclock was not set which led to incorrect timings sent to monitor.
