  • ddb53d48d   fbdev: remove cyblafb driver ... Browse Code »

    A tridentfb driver has all the functionality of the cyblafb driver without
    the bugs of the latter.

    Changes to the tridentfb driver:

    - FBINFO_READS_FAST added to the tridentfb. The cyblafb used a blitter
    for scrolling which is faster than color expansion on Cyberblade
    chipsets. The blitter is slower on a discrete Blade3D core. Use the
    blitter for scrolling in the tridentfb only for integrated Blade3D
    cores. Now, scrolling speed is about equal for the tridentfb and the
    cyblafb.

    - a copyright notice addition is done on request of Jani Monoses (the
    first author of the tridentfb).

    Tested on AGP Blade3D card and PCChips
    M787CLR motherboard: VIA C3 cpu +
    VT8601 north bridge (aka Cyberblade/i1).

  • 198fc108e   [ARM] pxafb: add support for overlay1 and overlay2 as framebuffer devices ... Browse Code »

    PXA27x and later processors support overlay1 and overlay2 on-top of the
    base framebuffer (although under-neath the base is also possible). They
    support palette and no-palette RGB formats, as well as YUV formats (only
    available on overlay2). These overlays have dedicated DMA channels and
    behave in a similar way as a framebuffer.

    This heavily simplified and re-structured work is based on the original
    pxafb_overlay.c (which is pending for mainline merge for a long time).

    The major problems with this pxafb_overlay.c are (if you are interested
    in the history):

    1. heavily redundant (the control logics for overlay1 and overlay2 are
    actually identical except for some small operations, which are now
    abstracted into a 'pxafb_layer_ops' structure)

    2. a lot of useless and un-tested code (two workarounds which are now
    fixed on mature silicons)

    3. cursorfb is actually useless, hardware cursor should not be used
    this way, and the code was actually un-tested for a long time.

    The code in this patch should be self-explanatory, I tried to add minimum
    comments. As said, this is basically simplified, there are several things
    still on the pending list:

    1. palette mode is un-supported and un-tested (although re-using the
    palette code of the base framebuffer is actually very easy now with
    previous clean-up patches)

    2. fb_pan_display for overlay(s) is un-supported

    3. the base framebuffer can actually be abstracted by 'pxafb_layer' as
    well, which will help further re-use of the code and keep a better
    and consistent structure. (This is the reason I named it 'pxafb_layer'
    instead of 'pxafb_overlay' or something alike)

    See Documentation/fb/pxafb.txt for additional usage information.

  • 77e196752   [ARM] pxafb: allow video memory size to be configurable ... Browse Code »

    The amount of video memory size is decided according to the following
    order:

    1. x x by default, which is the backward
    compatible way

    2. size specified in platform data

    3. size specified in module parameter 'options' string or specified in
    kernel boot command line (see updated Documentation/fb/pxafb.txt)

    And now since the memory is allocated from system memory, the pxafb_mmap
    can be removed and the default fb_mmap() should be working all right.

    Also, since we now have introduced the 'struct pxafb_dma_buff' for DMA
    descriptors and palettes, the allocation can be separated cleanly.

    NOTE: the LCD DMA actually supports chained transfer (i.e. page-based
    transfers), to simplify the logic and keep the performance (with less
    TLB misses when accessing from memory mapped user space), the memory
    is allocated by alloc_pages_*() to ensures it's physical contiguous.

  • 3f7a26b4b   intelfb: support 945GME (as used in ASUS Eee 901) ... Browse Code »

    Add support for Intel's 945GME graphics chip to the intelfb driver. I
    have assumed that the 945GME is identical to the already-supported 945GM
    apart from its PCI IDs; this is based on a quick look at the X driver for
    these chips which seems to treat them identically.

    The 945GME is used in the ASUS Eee 901, and I coded this in the hope that
    I'd be able to use it to get a console at the native 1024x600 resolution
    which is not known to the BIOS. I realised too late that the intelfb
    driver does not support mode changing on laptops, so it won't be any
    use for me.

  • 0e170c72c   fbdev: intelfb: add support for the Intel Integrated Graphics Controller 965G/965GM ... Browse Code »

    Add support for the 965G and 965GM graphic chipsets to the intelfb driver. I
    have a notebook with an Intel Mobile GM965/GL960 Integrated Graphics
    Controller and with the attached patch the framebuffer comes up. I have
    tested it a bit with DirectFB to make sure it is working stable.

    I also have an Intel Mobile GM945 and I compared the results, the programming
    interface of the 9xx series from Intel is mostly the same, so I think the
    patch should add all the functionality which the 945GM has.

  • b6f448e99   PM/gxfb: add hook to PM console layer that allows disabling of suspend VT switch ... Browse Code »

    Prior to suspend, we allocate and switch to a new VT; after suspend, we switch
    back to the original VT. This can be slow, and is completely unnecessary if
    the framebuffer we're using can restore video properly.

    This adds a hook that allows drivers to select whether or not to do this vt
    switch, and changes the gxfb driver to call this hook. It also adds a module
    param to gxfb to allow controlling of the vt switch (defaulting to no switch).

    (Note: I'm not convinced that console_sem is the best way to protect this, but
    we should probably have some form of locking..)

  • fa20c8a6e   gxfb: replace FBSIZE config option with a module parameter ... Browse Code »

    Use a command line option (vram) rather than hardcoding the vram size. LxFB
    already does this; it's useful for machines that can't query the BIOS for fb
    size. This patch originated from David Woodhouse, was modified by Jordan
    Crouse, and was then modified further by me.

    This also adds some gxfb documentation in Documentation/fb.

    Implement support for the E-Ink Metronome controller. It provides an mmapable
    interface to the controller using defio support. It was tested with a gumstix
    pxa255 with Vizplex media using Xfbdev and various X clients such as xeyes,
    xpdf, xloadimage.

    This patch also fixes the following bug: Defio would cause a hang on write
    access to the framebuffer as the page fault would be called ad-infinitum. It
    fixes fb_defio by setting the mapping to be used by page_mkclean.
