  • 1fb25cb8b   radeonfb: Fix resume from D3Cold on some platforms ... Browse Code »

    For historical reason, this driver used its own saving/restoring
    of the PCI config space, and used the state of it on resume as
    an indication as to whether it needed to re-POST the chip or not.

    This methods breaks with the later core changes since the core will
    have restored things for us.

    This patch fixes it by removing that custom code, using standard
    core methods to save/restore state, and testing for the need to
    re-POST by comparing the content of a few key PLL registers.

    This reverts commit b1ee26bab14886350ba12a5c10cbc0696ac679bf, along with
    the "fixes" for it that all just caused problems:

    - c4c6fa9891f3d1bcaae4f39fb751d5302965b566 "radeonfb: fix problem with
    color expansion & alignment"

    - f3179748a157c21d44d929fd3779421ebfbeaa93 "radeonfb: Disable new color
    expand acceleration unless explicitely enabled"

    because even when disabled, it breaks for people. See

    http://bugzilla.kernel.org/show_bug.cgi?id=12191

    for the latest example.

  • f3179748a   radeonfb: Disable new color expand acceleration unless explicitely enabled ... Browse Code »

    This new color expansion acceleration for radeonfb appears to trigger
    problems with X on VT switch and suspend/resume on some machines. It
    might be a problem in the VT layer or in X, but I haven't quite found
    it yet, so in the meantime, this disables the acceleration by default,
    reverting to 2.6.27 state. It can be enabled using the "accel_cexp"
    module parameter or fbdev argument.

  • b1ee26bab   radeonfb: accelerate imageblit and other improvements ... Browse Code »

    Implement support for HW color expansion of 1bpp images, along with some
    improvements to the FIFO handling and other accel operations.

    The offset fixup code is now unnecessary as the fbcon core will call our
    set_par upon switch back from KD_GRAPHICS before anything else happens. I
    removed it as it would slow down accel operations.

    The fifo wait has been improved to avoid hitting the HW register as often,
    and the various accel ops are now performing better caching of register
    values.

    Overall, this improve accel performances. The imageblit acceleration does
    result in a small overall regression in performances on some machines (on
    the order of 5% on some x86), probably becaus the SW path provides a
    better bus utilisation, but I decided to ingnore that as the performances
    is still very good, and on the other hand, some machines such as some
    sparc64 get a 3 fold performance improvement.

  • a6c0c37db   radeonfb: misc cleanup of engine and dst cache handling ... Browse Code »

    Fix a couple of incomplete tests of the chip families in the engine
    init/reset code and proper initialization of the destination cache mode.
    The result should better match what the latest X radeon driver does.

    RTRACE() does exactly the same thing as the standard pr_debug() call, so just
    use the latter.

    Fix CONFIG_FB_RADEON_DEBUG. DEBUG must be defined before including any kernel
    header, otherwise dev_dbg() resolves to a no-op. Also, when debugging is
    disabled, don't set DEBUG at all instead of setting it to 0, to comply with
    what the kernel headers expect.

    Make radeonfb work ith the 200m Xpress RC410. In my tests it was terribly
    unstable and would freeze until I set a refresh rate in the kernel argument
    to 75.

    e.g video=radeonfb:1280x800@75

    Now it is rock solid.

  • 994aad251   [PATCH] radeonfb sleep fixes ... Browse Code »

    Many IBM Thinkpad T4* models and some R* and X* with radeon video cards draw
    too much power when suspended to RAM, reducing drastically the battery
    lifetime. The solution is to enable suspend-to-D2 on these machines. They
    are whitelisted through their subsystem vendor/device ID. This fixes
    http://bugzilla.kernel.org/show_bug.cgi?id=3022

    The patch introduces a framework to alter the pm_mode and reinit_func fields
    of the radeonfb_info structure based on a whitelist. This should facilitate
    future hardware-dependent workarounds. The workaround for the Samsung P35
    that is already in the radeonfb code has been rewritten using this framework.

    The behavior can be overridden with module options:

    i) video=radeonfb:force_sleep=1
    enable suspend-to-D2 also on non-whitelisted machines (useful for
    testing new notebook models),

    ii) video=radeonfb:ignore_devlist=1
    Disable checking the whitelist and do not apply any workarounds.

  • 5474c120a   [PATCH] Rewritten backlight infrastructure for portable Apple computers ... Browse Code »

    This patch contains a total rewrite of the backlight infrastructure for
    portable Apple computers. Backward compatibility is retained. A sysfs
    interface allows userland to control the brightness with more steps than
    before. Userland is allowed to upload a brightness curve for different
    monitors, similar to Mac OS X.

    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!
