- 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=<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 gxfb with gxfb.<option>.
- For example, gxfb.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.
