Tridentfb is a framebuffer driver for some Trident chip based cards.
The following list of chips is thought to be supported although not all are
tested:
those from the Image series with Cyber in their names - accelerated
those with Blade in their names (Blade3D,CyberBlade...) - accelerated
the newer CyberBladeXP family - nonaccelerated
Only PCI/AGP based cards are supported, none of the older Tridents.
How to use it?
==============
Just do your usual console work :)
When booting you can pass the following parameters
==================================================
noaccel - turns off acceleration (when it doesn't work for your card)
accel - force text acceleration (for boards which by default are noacceled)
fp - use flat panel related stuff
crt - assume monitor is present instead of fp
center - for flat panels and resolutions smaller than native size center the
image, otherwise use
stretch
memsize - integer value in Kb, use if your card's memory size is misdetected.
look at the driver output to see what it says when initializing.
memdiff - integer value in Kb,should be nonzero if your card reports
more memory than it actually has.For instance mine is 192K less than
detection says in all three BIOS selectable situations 2M, 4M, 8M.
Only use if your video memory is taken from main memory hence of
configurable size.Otherwise use memsize.
If in some modes which barely fit the memory you see garbage at the bottom
this might help by not letting change to that mode anymore.
nativex - the width in pixels of the flat panel.If you know it (usually 1024
800 or 1280) and it is not what the driver seems to detect use it.
bpp - bits per pixel (8,16 or 32)
mode - a mode name like 800x600 (as described in Documentation/fb/modedb.txt)
Using insane values for the above parameters will probably result in driver
misbehaviour so take care(for instance memsize=12345678 or memdiff=23784 or
nativex=93)

/*
* linux/drivers/video/skeletonfb.c -- Skeleton for a frame buffer device
*
* Modified to new api Jan 2001 by James Simmons (jsimmons@transvirtual.com)
*
* Created 28 Dec 1997 by Geert Uytterhoeven
*
*
* I have started rewriting this driver as a example of the upcoming new API
* The primary goal is to remove the console code from fbdev and place it
* into fbcon.c. This reduces the code and makes writing a new fbdev driver
* easy since the author doesn't need to worry about console internals. It
* also allows the ability to run fbdev without a console/tty system on top
* of it.
*
* First the roles of struct fb_info and struct display have changed. Struct
* display will go away. The way the the new framebuffer console code will
* work is that it will act to translate data about the tty/console in
* struct vc_data to data in a device independent way in struct fb_info. Then
* various functions in struct fb_ops will be called to store the device
* dependent state in the par field in struct fb_info and to change the
* hardware to that state. This allows a very clean seperation of the fbdev
* layer from the console layer. It also allows one to use fbdev on its own
* which is a bounus for embedded devices. The reason this approach works is
* for each framebuffer device when used as a tty/console device is allocated
* a set of virtual terminals to it. Only one virtual terminal can be active
* per framebuffer device. We already have all the data we need in struct
* vc_data so why store a bunch of colormaps and other fbdev specific data
* per virtual terminal.
*
* As you can see doing this makes the con parameter pretty much useless
* for struct fb_ops functions, as it should be. Also having struct
* fb_var_screeninfo and other data in fb_info pretty much eliminates the
* need for get_fix and get_var. Once all drivers use the fix, var, and cmap
* fbcon can be written around these fields. This will also eliminate the
* need to regenerate struct fb_var_screeninfo, struct fb_fix_screeninfo
* struct fb_cmap every time get_var, get_fix, get_cmap functions are called
* as many drivers do now.

* struct fb_info. Now the struct xxx_par represents the graphics
* hardware state thus only one exist per card. In this case the

* This allows when one display changes it video resolution (info->var)
* the other displays know instantly. Each display can always be
* aware of the entire hardware state that affects it because they share
* the same xxx_par struct. The other side of the coin is multiple
* graphics cards that pass data around until it is finally displayed
* on one monitor. Such examples are the voodoo 1 cards and high end
* NUMA graphics servers. For this case we have a bunch of pars, each
* one that represents a graphics state, that belong to one struct
* fb_info. Their you would want to have *par point to a array of device
* states and have each struct fb_ops function deal with all those
* states. I hope this covers every possible hardware design. If not
