From 9fa68eae9f8291a98bfe00b94b78f72eb253165a Mon Sep 17 00:00:00 2001 From: Knut Petersen Date: Fri, 9 Sep 2005 13:04:56 -0700 Subject: [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 Cc: Muli Ben-Yehuda Acked-by: Antonino Daplas Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- drivers/video/Kconfig | 31 ++++++++++++++++++++++++++++++- 1 file changed, 30 insertions(+), 1 deletion(-) (limited to 'drivers/video/Kconfig') diff --git a/drivers/video/Kconfig b/drivers/video/Kconfig index e906b5421795..e27aefd49ea3 100644 --- a/drivers/video/Kconfig +++ b/drivers/video/Kconfig @@ -1177,6 +1177,32 @@ config FB_VOODOO1 Please read the for supported options and other important info support. +config FB_CYBLA + tristate "Cyberblade/i1 support" + depends on FB && PCI + select FB_CFB_IMAGEBLIT + select FB_SOFT_CURSOR + select VIDEO_SELECT + ---help--- + 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 . + + To compile this driver as a module, choose M here: the + module will be called cyblafb. + config FB_TRIDENT tristate "Trident support" depends on FB && PCI @@ -1190,8 +1216,12 @@ config FB_TRIDENT but also on some motherboards.
