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 linux-fbdev-devel, Signed-off-by: Knut Petersen <Knut_Petersen@t-online.de> Cc: Muli Ben-Yehuda <mulix@mulix.org> Acked-by: Antonino Daplas <adaplas@pol.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

TODO / Missing features
|
|
=======================
|
|
|
|
Verify LCD stuff "stretch" and "center" options are
|
|
completely untested ... this code needs to be
|
|
verified. As I don't have access to such
|
|
hardware, please contact me if you are
|
|
willing run some tests.
|
|
|
|
Interlaced video modes The reason that interleaved
|
|
modes are disabled is that I do not know
|
|
the meaning of the vertical interlace
|
|
parameter. Also the datasheet mentions a
|
|
bit d8 of a horizontal interlace parameter,
|
|
but nowhere the lower 8 bits. Please help
|
|
if you can.
|
|
|
|
low-res double scan modes Who needs it?
|
|
|
|
accelerated color blitting Who needs it? The console driver does use color
|
|
blitting for nothing but drawing the penguine,
|
|
everything else is done using color expanding
|
|
blitting of 1bpp character bitmaps.
|
|
|
|
xpanning Who needs it?
|
|
|
|
ioctls Who needs it?
|
|
|
|
TV-out Will be done later
|
|
|
|
??? Feel free to contact me if you have any
|
|
feature requests
