inteldrmfb api

fwmiller · 12-04-2009, 11:51 PM

I have a kernel 2.6.31 booting from a USB stick using Intel 915 based KMS to get to graphics mode. It appears to be setting itself to the native resolution and its booting nicely into framebuffer console with a beautiful Tux logo!

Question is, how do I access the inteldrmfb? How do I get it into /dev? Will udev do this for me?

What is the API for programming the framebuffer directly?

Thanks,
FM

I good API for the frame buffer is DirectFB, check it out, some distro's even use it for there setups and some even rely on it for the compilation of mplayer (without x)

Thanks for the reply. What I'm interested in is the API for direct access to the framebuffer itself, i.e. /dev/fb0 or whatever it is. This would be the API that something like DirectFB would make use of.
