Frame Buffer driver

[Altera_Forum]

Hello! 

I'm new in uCLinux. I'm writing a frame buffer driver, but I can't find information about writing drivers for Linux. Please help, where I can find documentation. Somebody wrote such driver? Is it possible to run Linux and frame buffer from the same sdram? Thanks!

If you use Altera&#39;s VGA core, you will surely run Linux and frame buffer from the same sdram. You may look at the wiki page, and linux.2.6.x/Documents, http://nioswiki.jot.com/wikihome/operating...duleprogarmming (http://nioswiki.jot.com/wikihome/operatingsystems/moduleprogarmming)  You may find many frame buffer drivers in linux-2.6.x/drivers/video. You may use vfb.c as a starting point.

What is "Altera&#39;s VGA core" ? I use in my project vga controller from "auto_graphics_referece_defign_v1.4"
