  • 9201a8584   savagefb: speed up the I2C bus ... Browse Code »

    There is no reason to drive the savagefb I2C bus at such a low speed, so bump
    it from 12.5 kbps to 50 kbps. The Intel (i810) and Matrox framebuffer drivers
    already run their I2C bus at this speed, and so are the legacy i2c-savage4 and
    i2c-prosavage drivers.

  • 22d832edc   savagefb: VGA state save and restore ... Browse Code »

    Allow the saving and restoration of VGA text mode. The state is saved on the
    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.

    An echo 0 > /sys/class/vtconsole/vtcon1/bind will convert the display from
    graphics to text mode.

  • 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).

    i2c-algo-bit: Discard the mdelay data struct member

    The i2c_algo_bit_data structure has an mdelay member, which is not
    used by the algorithm code (the code has always been ifdef'd out.)
    Let's discard it to save some code and memory.

  • f8020dc56   [PATCH] savagefb: Add state save and_restore hooks ... Browse Code »

    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).)

  • 6d83b0bb8   [PATCH] savagefb: X-panning fixes ... Browse Code »

    The driver unconditionally sets xpanstep to 2. However, a value of 4
    empirically works better at bpp = 8, and 2 for 16 and 32. This buglet was
    exposed by the rotation code.

    Second fix is the unconditional call to update_start() without verifying if
    the offsets are correct. Remove this call, it's not necessary and secondly,
    it causes a crash with invalid values.

  • 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.

  • 1684a9843   [PATCH] I2C: Kill i2c_algorithm.id (6/7) ... Browse Code »

    In theory, there should be no more users of I2C_ALGO_* at this point.
    However, it happens that several drivers were using I2C_ALGO_* for
    adapter ids, so we need to correct these before we can get rid of all
    the I2C_ALGO_* definitions.

    Note that this also fixes a bug in media/video/tvaudio.c:

    /* don't attach on saa7146 based cards,
    because dedicated drivers are used */
    if ((adap->id & I2C_ALGO_SAA7146))
    return 0;

    This test was plain broken, as it would succeed for many more adapters
    than just the saa7146: any those id would share at least one bit with
    the saa7146 id. We are really lucky that the few other adapters we want
    this driver to work with did not fulfill that condition.
