Introduction -=============== - -This is a framebuffer driver for various Intel 8xx/9xx compatible -graphics devices. These would include: - - - Intel 830M - - Intel 845G - - Intel 852GM - - Intel 855GM - - Intel 865G - - Intel 915G - - Intel 915GM - - Intel 945G - - Intel 945GM - - Intel 945GME - - Intel 965G - - Intel 965GM - -B. List of available options -============================= - - a. "video=intelfb" - enables the intelfb driver - - Recommendation: required - - b. "mode=<xres>x<yres>[-<bpp>][@<refresh>]" - select mode - - Recommendation: user preference - (default = 1024x768-32@70) - - c. "vram=<value>" - select amount of system RAM in MB to allocate for the video memory - if not enough RAM was already allocated by the BIOS. - - Recommendation: 1 - 4 MB. - (default = 4 MB) - - d. "voffset=<value>" - select at what offset in MB of the logical memory to allocate the - framebuffer memory. The intent is to avoid the memory blocks - used by standard graphics applications (XFree86). Depending on your - usage, adjust the value up or down, (0 for maximum usage, 63/127 MB - for the least amount). Note, an arbitrary setting may conflict - with XFree86. - - Recommendation: do not set - (default = 48 MB) - - e. "accel" - enable text acceleration. This can be enabled/reenabled anytime - by using 'fbset -accel true/false'. - - Recommendation: enable - (default = set) - - f. "hwcursor" - enable cursor acceleration. - - Recommendation: enable - (default = set) - - g. "mtrr" - enable MTRR. This allows data transfers to the framebuffer memory - to occur in bursts which can significantly increase performance. - Not very helpful with the intel chips because of 'shared memory'. - - Recommendation: set - (default = set) - - h. "fixed" - disable mode switching. - - Recommendation: do not set - (default = not set) - - The binary parameters can be unset with a "no" prefix, example "noaccel". - The default parameter (not named) is the mode. - -C. Kernel booting -================= - -Separate each option/option-pair by commas (,) and the option from its value -with an equals sign (=) as in the following:: - - video=intelfb:option1,option2=value2 - -Sample Usage ------------- - -In /etc/lilo.conf, add the line:: - - append="video=intelfb:mode=800x600-32@75,accel,hwcursor,vram=8" - -This will initialize the framebuffer to 800x600 at 32bpp and 75Hz. The -framebuffer will use 8 MB of System RAM. hw acceleration of text and cursor -will be enabled. - -Remarks -------- - -If setting this parameter doesn't work (you stay in a 80x25 text-mode), -you might need to set the "vga=<mode>" parameter too - see vesafb.txt -in this directory. - - -D. Module options -================== - -The module parameters are essentially similar to the kernel -parameters. The main difference is that you need to include a Boolean value -(1 for TRUE, and 0 for FALSE) for those options which don't need a value. - -Example, to enable MTRR, include "mtrr=1". - -Sample Usage ------------- - -Using the same setup as described above, load the module like this:: - - modprobe intelfb mode=800x600-32@75 vram=8 accel=1 hwcursor=1 - -Or just add the following to a configuration file in /etc/modprobe.d/:: - - options intelfb mode=800x600-32@75 vram=8 accel=1 hwcursor=1 - -and just do a:: - - modprobe intelfb - - -E. Acknowledgment: -=================== - - 1. Geert Uytterhoeven - his excellent howto and the virtual - framebuffer driver code made this possible. - - 2. Jeff Hartmann for his agpgart code. - - 3. David Dawes for his original kernel 2.4 code. - - 4. The X developers. Insights were provided just by reading the - XFree86 source code. - - 5. Antonino A. Daplas for his inspiring i810fb driver. - - 6. Andrew Morton for his kernel patches maintenance. - -Sylvain |
