3	What is gxfb?
4	=================
5	
6	This is a graphics framebuffer driver for AMD Geode GX2 based processors.
7	
8	Advantages:
9	
10	 * No need to use AMD's VSA code (or other VESA emulation layer) in the
11	   BIOS.
12	 * It provides a nice large console (128 cols + 48 lines with 1024x768)
13	   without using tiny, unreadable fonts.
14	 * You can run XF68_FBDev on top of /dev/fb0
15	 * Most important: boot logo :-)
16	
17	Disadvantages:
18	
19	 * graphic mode is slower than text mode...
20	
21	
22	How to use it?
23	==============
24	
25	Switching modes is done using  gxfb.mode_option=<resolution>... boot
26	parameter or using `fbset' program.
27	
28	See Documentation/fb/modedb.txt for more information on modedb
29	resolutions.

32	X11
33	===
34	
35	XF68_FBDev should generally work fine, but it is non-accelerated.
36	
37	
38	Configuration
39	=============
40	
41	You can pass kernel command line options to gxfb with gxfb.<option>.
42	For example, gxfb.mode_option=800x600@75.
43	Accepted options:
44	
45	mode_option	- specify the video mode.  Of the form
46			  <x>x<y>[-<bpp>][@<refresh>]
47	vram		- size of video ram (normally auto-detected)
48	vt_switch	- enable vt switching during suspend/resume.  The vt
49			  switch is slow, but harmless.
