7 This is a graphics framebuffer driver for AMD Geode GX2 based processors.
11 * No need to use AMD's VSA code (or other VESA emulation layer) in the
13 * It provides a nice large console (128 cols + 48 lines with 1024x768)
14 without using tiny, unreadable fonts.
15 * You can run XF68_FBDev on top of /dev/fb0
16 * Most important: boot logo :-)
20 * graphic mode is slower than text mode...
26 Switching modes is done using gxfb.mode_option=<resolution>... boot
27 parameter or using `fbset` program.
29 See Documentation/fb/modedb.rst for more information on modedb
36 XF68_FBDev should generally work fine, but it is non-accelerated.
42 You can pass kernel command line options to gxfb with gxfb.<option>.
43 For example, gxfb.mode_option=800x600@75.
46 ================ ==================================================
47 mode_option specify the video mode. Of the form
48 <x>x<y>[-<bpp>][@<refresh>]
49 vram size of video ram (normally auto-detected)
50 vt_switch enable vt switching during suspend/resume. The vt
51 switch is slow, but harmless.
