2009-04-01fbdev: remove cyblafb driverKrzysztof Helt
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).

2006-01-09[PATCH] Update cyblafb driverKnut Petersen
This is a major update to the cyblafb framebuffer driver. Most of the stuff has been tested in the mm tree. Main advantages: ============ - vxres > xres support - ywrap and xpan support - much faster for almost all modes (e.g. 1280x1024-16bpp draws more than 41 full screens of text instead of about 25 full screens of text per second on authors Epia 5000) - module init/exit code fixed - bugs triggered by console rotation fixed - lots of minor improvements - startup modes suitable for high performance scrolling in all directions This diff also contains a lot of white space fixes. No side effects are possible, only one single graphics core is affected. Signed-off-by: Knut Petersen <Knut_Petersen@t-online.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-09-09[PATCH] framebuffer: new driver for cyberblade/i1 graphics coreKnut Petersen
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>
