What is gxfb?

This is a graphics framebuffer driver for AMD Geode GX2 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 gxfb.mode_option=… 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 gxfb with gxfb.

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