Re: Framebuffer driver using SM501 hardware.

Hi!

I was working with the SM501 framebuffer for a while on
linux-2.6.

It is heavily based on old silicon motion code and
not in good shape, so I didn't dare to publish it ;-)

But it's working on ppc, linux-2.6 and X was running on it.
There is a color-mapping issue left (RGB is swapped on powerpc)
and it needs lots of code cleanup or a complete rewrite.

Due to my project schedule, it will take me some month
until I can focus on the voyagerfb again.

But take what you want...

Best greets,

Clemens Koller

Hi all,

I am writing framebuffer driver using SM501. This graphics driver chip can
drive CRT and TFT panel. I have written two seperate framebuffer driver, one
for CRT and one for TFT Panel.

But I am not able to test both the devices. Any one of them work at a time.
I have created two files /dev/fb0 and /dev/fb1. These two can be open
successfully and mmap is also successful from userspace. If I am trying to
write on fb0 and  fb1 with different data, they displayed on either CRT or
TFT panel.

Can any one help me How to test two different framebuffer devices?

Thanks.
