  • 48c68c4f1   Drivers: video: remove __dev* attributes. ... Browse Code »

    CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
    markings need to be removed.

    This change removes the use of __devinit, __devexit_p, __devinitdata,
    __devinitconst, and __devexit from these drivers.

    Based on patches originally written by Bill Pemberton, but redone by me
    in order to handle some of the coding style issues better, by hand.

  • 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.

  • 3a2d5b700   PM: Introduce PM_EVENT_HIBERNATE callback state ... Browse Code »

    During the last step of hibernation in the "platform" mode (with the
    help of ACPI) we use the suspend code, including the devices'
    ->suspend() methods, to prepare the system for entering the ACPI S4
    system sleep state.

    But at least for some devices the operations performed by the
    ->suspend() callback in that case must be different from its operations
    during regular suspend.

    For this reason, introduce the new PM event type PM_EVENT_HIBERNATE and
    pass it to the device drivers' ->suspend() methods during the last phase
    of hibernation, so that they can distinguish this case and handle it as
    appropriate. Modify the drivers that handle PM_EVENT_SUSPEND in a
    special way and need to handle PM_EVENT_HIBERNATE in the same way.

    These changes are necessary to fix a hibernation regression related
    to the i915 driver (ref. http://lkml.org/lkml/2008/2/22/488).

  • 74f482cca   fb: nvidiafb: Try harder at initial mode setting. ... Browse Code »

    The current nvidiafb_check_var() simply bails out if the selected mode is
    out of range of the panel dimensions. A good question would be why the
    bogus mode is being selected in the first place -- the panel dimensions
    that are read back are certainly bogus, but alas, I have no idea where to
    even begin looking at the i2c/EDID/DDC mess:

    nvidiafb: Device ID: 10de0165
    nvidiafb: CRTC0 analog not found
    nvidiafb: CRTC1 analog not found
    nvidiafb: EDID found from BUS1
    nvidiafb: CRTC 0 is currently programmed for DFP
    nvidiafb: Using DFP on CRTC 0
    nvidiafb: Panel size is 1280 x 1024
    nvidiafb: Panel is TMDS
    nvidiafb: unable to setup MTRR
    nvidiafb: Flat panel dithering disabled
    nvidiafb: PCI nVidia NV16 framebuffer (64MB @ 0xC0000000)

    In my .config I presently have:

    CONFIG_FIRMWARE_EDID=y
    CONFIG_FB_DDC=y
    CONFIG_FB_NVIDIA_I2C=y

    I've not tried fiddling with these options, as I haven't the vaguest idea
    what I should be looking at.

    As a workaround, simply groveling for a new mode based on the probed
    dimensions seems to work ok. While it would be nice to debug this further
    and sort out why the panel information is bogus, I think it's still worth
    retrying the mode based on the panel information at hand as a last-ditch
    effort, rather than simply bailing out completely.

  • 3c03ec209   nvidiafb: Add boot option to reverse i2c port assignment ... Browse Code »

    There are a few nvidia hardware where the i2c port assignments are reversed,
    i.e., the 1st i2c port is assigned to the secondary display and the 2nd i2c
    port to the primary display. In most cases, if only 1 display is attached, or
    if only 1 flatpanel and 1 analog display is attached, the port reversal is of
    no consequence. However if 2 flatpanels are attached, it can cause display
    problems.

    There is no sane way of determining if the hardware reversed the i2c port
    assignment, so the simplest fix is to add a boot/module option, "reverse_i2c
    to explicitly reverse the i2c port.

    This also restores i2c ordering back to the pre-2.6.22 state.

  • ce38cac48   [PATCH] rivafb/nvidiafb: race between register_framebuffer and *_bl_init ... Browse Code »

    Since we now use the generic backlight infrastructure, I think we need to
    call rivafb_bl_init before calling register_framebuffer since otherwise
    rivafb_bl_init might race with the framebuffer layer already opening the
    device and setting up the video mode. In this case we might end up with a
    not yet fully intialized backlight (info->bl_dev still NULL) when calling
    riva_bl_set_power via rivafb_set_par/rivafb_load_video_mode and the kernel
    dies without any further notice during boot.

    This fixes booting current git on a PB 6,1. In this case radeonfb/atyfb
    would be affected too - I can fix that too but don't have any hardware to
    test this on.

  • e01af0384   [PATCH] powermac: Combined fixes for backlight code ... Browse Code »

    This patch fixes several problems:
    - pmac_backlight_key() is called under interrupt context, and therefore
    can't use mutexes or semaphores, so defer the backlight level for
    later, as it's not critical (original code by Aristeu S. Rozanski F.
    ).
    - Add exports for functions that might be called from modules
    - Fix Kconfig depdencies on PMAC_BACKLIGHT.
    - Fix locking issues on calls from inside the driver (reported by
    Aristeu S. Rozanski F., too)
    - Fix wrong calculation of backlight values in some of the drivers
    - Replace pmac_backlight_key_up/down by inline functions

    We now have a machine_is() macro that replaces the comparisons of
