[PATCH] framebuffer: new driver for cyberblade/i1 graphics core
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>

+ This driver is supposed to support the Trident Cyberblade/i1
+ graphics core integrated in the VIA VT8601A North Bridge,
+ also known as VIA Apollo PLE133.
+
+ Status:
+ - Developed, tested and working on EPIA 5000 and EPIA 800.
+ - Does work reliable on all systems with CRT/LCD connected to
+ normal VGA ports.
+ - Should work on systems that do use the internal LCD port, but
+ this is absolutely not tested.
+
+ Character imageblit, copyarea and rectangle fill are hw accelerated,
+ ypan scrolling is used by default.
+
+ Please do read <file:Documentation/fb/cyblafb/*>.
+
+ To compile this driver as a module, choose M here: the
+ module will be called cyblafb.
