Intel(R) 810 and 815 Framebuffer Driver

News (27-05-2004)

I plan to add DDC/I2C support to the driver. With DDC, the i810fb can automatically get the information about the attached monitor from the hardware itself and pass it via EDID. The EDID contains useful information such as the best modeline as well as the operational limits of the monitor.

However, I will need testers since I don't have the hardware. To test this:

You will need linux-2.6.6 source tree.
Download i810fb-i2c.diff.
Apply patch (cd /usr/src/linux-2.6.6 && cat i810fb-i2c.dif | patch -p1)
Do your usual config and enable the following:

I2C support (under Device Drivers->I2C Support)
I2C Device Interface (under Device Drivers->I2C Support
I2C bit-banging interfaces (under Device Drivers->I2C Support->I2C Algorithms)
DDC Support for the Intel 810 Framebuffer Driver (under Device Drivers->Graphics)

Compile and Reboot
Check dmesg. You see a lot of output about EDID pertaining to your display device.
Email me the pertinent parts of dmesg as well as the output of lspci -vvv at adaplas@users.sourceforge.net.

Note: This patch is for informational purposes only. It should not affect the functionality of the driver.
Note2: Some i810 chipsets have no DDC support which is the reason why I also need the lspci output.

Thanks.

I'm back. I've been busy for the most part of last year that I have neglected this project and even failed to answer most e-mails. One more thing, I don't have any access to any Intel 810 or 815 machines anymore, so it will be difficult to add features to the driver. However, I'll still try to do my best to submit patches/updates. Just let me know. (This time, I'll be around :-).

Project Information:

This project is an attempt to add a framebuffer driver for the integrated graphics of the Intel(R) 810 and 815 chipset family. As part of this attempt, a DirectFB gfxdriver is also being developed.

If you want an overview of the changes per version, read the summarized changelog. Check this out for more information.

Other Projects:

I'm also trying to extend the functionality of the VESA framebuffer driver. The result is vm86d, an x86 user daemon that can run BIOS services. This will allow the VESA framebuffer driver to support changing of video modes without having to reboot. Works very nicely on my machine. It is still very alpha, and it requires a developmental kernel, linux-2.5.66.

*With the i810fb package, you will need the XFree86 Patches
**With the i810fb-lite package, the XFree86 patches are NOT necessary.
***Note: the later versions have support for i810fb-lite and the i810fb driver in linux-2.5.xx. Please use this instead if you need to maintain compatibility with future kernel versions.

The modules were compiled with gcc-2.95.3.

Installation Guide:

For information on how to install, set up and use the framebuffer driver, please refer to the online Intel 810/815 Framebuffer HOWTO. You can also download the guide as a tarball in bz2 or gz format.
