  • 4b00e4b39   savagedb: Fix typo causing regression in savage4 series video chip detection ... Browse Code »
    1

    Two additional savage4 variants were added, but the S3_SAVAGE4_SERIES
    macro was incompletely modified, resulting in a false positive detection
    of a savage4 card regardless of which savage card is actually present.

    For non-savage4 series cards, such as a Savage/IX-MV card, this results
    in garbled video and/or a hard-hang at boot time. Fix this by changing
    an '||' to an '&&' in the S3_SAVAGE4_SERIES macro.

  • 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.

  • f0a2f357d   savagefb: fix DDC for Savage 4 ... Browse Code »

    I tested savagefb on 3 different Savage 4 cards:
    Diamond Stealth III S520
    Number Nine SR9
    Datapath Horizon 2S (two savage chips on a PCI card)

    it worked except the DDC which did not work on any of them.

    Looking at the BIOS code, it does not use MMIO register 0xff20 but CRT
    register 0xa0 or 0xb1 - depending on the chip revision and something in
    register 0xa6. With this patch, DDC works fine on all 3 cards (even on
    the second head of Horizon 2S - although it does not display anything as
    it's misconfigured because of missing BIOS).

  • 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.

  • f5c15d0b3   fb: remove fb_save_state() and fb_restore_state operations ... Browse Code »

    Remove fb_save_state() and fb_restore_state operations from frame buffer layer.
    They are used only in two drivers:
    1. savagefb - and cause bug #11248
    2. uvesafb

    Usage of these operations is misunderstood in both drivers so kill these
    operations, fix the bug #11248 and avoid confusion in the future.

    Tested on Savage 3D/MV card and the patch fixes the bug #11248.

    The frame buffer layer uses these funtions during switch between graphics
    and text mode of the console, but these drivers saves state before
    switching of the frame buffer (in the fb_open) and after releasing it (in
    the fb_release). This defeats the purpose of these operations.

    first open and restored on the last close. Because of the VGA registers are
    linearly mapped to the MMIO space, MMIO access is used which is not limited to
    X86 platforms nor to the primary display device.

  • cd354f1ae   [PATCH] remove many unneeded #includes of sched.h ... Browse Code »

    After Al Viro (finally) succeeded in removing the sched.h #include in module.h
    recently, it makes sense again to remove other superfluous sched.h includes.
    There are quite a lot of files which include it but don't actually need
    anything defined in there. Presumably these includes were once needed for
    macros that used to live in sched.h, but moved to other header files in the
    course of cleaning it up.

    To ease the pain, this time I did not fiddle with any header files and only
    removed #includes from .c-files, which tend to cause less trouble.

    Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
    arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
    allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
    configs in arch/arm/configs on arm. I also checked that no new warnings were
    introduced by the patch (actually, some warnings are removed that were emitted
    by unnecessarily included header files).

    Reported by: Rich (Bugzilla Bug 6417)

    "if savage driver is used in x.org together with savagefb, it results in
    seriously garbled and distorted screen - coupled with severe slowdowns."

    This bug is the result of Xorg unable to handle savagefb altering the
    hardware which results in X failing to start properly and/or failed console
    switching.

    Add savagefb_state_save and savagefb_state_restore. These hooks will only
    save and restore the extended VGA registers. Standard VGA registers will be
    left alone. This is enough to make savagefb play nicely with the latest
    Xorg savage driver, and perhaps with savage DRI. (Transient screen artifacts
    may appear before X loads and during console switches).

    (Unfortunately, blanking the screen also leaves Xorg in a blanked state, so I
    have to unblank the screen before Xorg loads. So I doubt if the transient
    screen artifacts will be completely invisible but hopefully it will only be
    for a shorter duration (not much).)
