    [PATCH] framebuffer: new driver for cyberblade/i1 graphics core · 9fa68eae
    Knut Petersen authored
    This is a framebuffer driver for the Cyberblade/i1 graphics core.
    Currently tridenfb claims to support the cyberblade/i1 graphics core.  This
    is of very limited truth.  Even vesafb is faster and provides more working
    modes and a much better quality of the video signal.  There is a great
    number of bugs in tridentfb ...  but most often it is impossible to decide
    if these bugs are real bugs or if fixing them for the cyberblade/i1 core
    would break support for one of the other supported chips.
    Tridentfb seems to be unmaintained,and documentation for most of the
    supported chips is not available.  So "fixing" cyberblade/i1 support inside
    of tridentfb was not an option, it would have caused numerous
    if(CYBERBLADEi1) else ...  cases and would have rendered the code to be
    almost unmaintainable.
    A first version of this driver was published on 2005-07-31.  A fix for a
    bug reported by Jochen Hein was integrated as well as some changes
    requested by Antonino A.  Daplas.
    A message has been added to tridentfb to inform current users of tridentfb
    to switch to cyblafb if the cyberblade/i1 graphics core is detected.
    This patch is one logical change, but because of the included documentation
    it is bigger than 70kb.  Therefore it is not sent to lkml and
