What is lxfb?
=================

This is a graphics framebuffer driver for AMD Geode LX based processors.

Advantages:

 * No need to use AMD's VSA code (or other VESA emulation layer) in the
   BIOS.
 * It provides a nice large console (128 cols + 48 lines with 1024x768)
   without using tiny, unreadable fonts.
 * You can run XF68_FBDev on top of /dev/fb0
 * Most important: boot logo :-)

Disadvantages:

 * graphic mode is slower than text mode...


How to use it?
==============

Switching modes is done using  lxfb.mode_option=<resolution>... boot
parameter or using `fbset' program.

See Documentation/fb/modedb.txt for more information on modedb
resolutions.


X11
===

XF68_FBDev should generally work fine, but it is non-accelerated.


Configuration
=============

You can pass kernel command line options to lxfb with lxfb.<option>.
For example, lxfb.mode_option=800x600@75.
Accepted options:

mode_option	- specify the video mode.  Of the form
		  <x>x<y>[-<bpp>][@<refresh>]
vram		- size of video ram (normally auto-detected)
vt_switch	- enable vt switching during suspend/resume.  The vt
		  switch is slow, but harmless.
