Video Driver

I'm looking at integrating a 65545 vga graphics controller chip into an embedded linux platform. I'll need to write a driver for it, but I'm not sure where to start. It's a fairly common chip, so I suspect that there's probably a driver out there already. Where would I find the source code? Could anyone point me to some resources and writing video drivers?

Thanks

Dan

Dan,

It's a standard VGA chipset, so the linux kernel can talk directly to it in text mode. If you want graphics, then you'll need to use SVGALib, kernel framebuffer or an X server (i.e. XFree86, X.org) A quick google just showed up pre-written drivers for all of these, look for Chips & Technologies CT-65545.

regards,

text mode.

X

My understanding is that i need a kernel framebuffer and nano-X.

This isn't an i386 platform, so I'll need source code. Where would I go about finding it? Sorry if the answer seems obvious.

text mode.

an X

I'm not familiar with nano-X, but that sounds like a useable solution.

Actually, upon further searching, it looks like there isn't a kernel framebuffer driver, but SVGAlib and XFree86 are open source so you should be able to use driver code from either of them.
