  • e4c690e06   fb: add support for foreign endianness ... Browse Code »

    Add support for the framebuffers with non-native endianness. This is done via
    FBINFO_FOREIGN_ENDIAN flag that will be used by the drivers. Depending on the
    host endianness this flag will be overwritten by FBINFO_BE_MATH internal flag,
    or cleared.

    Tested to work on MPC8360E-RDK (BE) + Fujitsu MINT framebuffer (LE).

  • 15afdd433   fbdev: copyarea function taught to fully support swapped pixel order in byte ... Browse Code »

    This correct case, when source and destination X coordinates difference is n
    multiple of pixels in byte. This is probably rare case, but this case should
    supported for completeness.

    Reorganization of FB_READL and FB_WRITEL calls results in code size decrease
    for normal build without swapping support and size with support enabled is
    reasonable too.

    [adaplas]
    Add missing fb_rev_pixels_in_long() prototype.

  • 779121e9f   fbdev: Support for byte-reversed framebuffer formats ... Browse Code »

    Allow generic frame-buffer code to correctly write texts and blit images for
    1, 2 and 4 bit per pixel frame-buffer organizations when pixels in bytes are
    organized to in opposite order than bytes in long type.

    Overhead should be reasonable. If option is not selected, than compiler
    should eliminate completely all overhead.

    The feature is disabled at compile time if CONFIG_FB_CFB_REV_PIXELS_IN_BYTE is
    not set.

    [adaplas]
    Convert helper functions to macros if feature is not enabled.
