cirrusfb not working?

cirrusfb not working?

[Emmanouel Vasilakis]

Hi,

I was trying a few days ago to boot a recent 2.6 kernel on my Amiga 3000.

 From what I found online, in order to get a framebuffer display from my 
Picasso IV, I needed to use the cirrusfb driver to the kernel which 
replaced the older clgen driver (In latest 2.6 kernels).

I tried stuff like:

amiboot -k vmlinuz video=cirrusfb:

No matter what I append to the video parameter, I can never get a 
display from the graphics card, it always comes up from the native ECS. 
Kernel messages say that a cirrusfb supported card was found. I was then 
told that cirrusfb does not work as expected, so any information on that?

What eventually worked somehow, was: video=amifb:off, which produced a 
display from the Picasso, but was full of garbage.

Thanks,
Emmanuel

Try cirrusfb:640x480 or something


Default video modes
-------------------
At the moment, there are two kernel command line arguments supported:

mode:640x480
mode:800x600
	or
mode:1024x768

Full support for startup video modes (modedb) will be integrated soon.

Did try those opts, and everything else I could think off. No go.

Am I supposed to see the kernel booting in that resolution, or will it 
first boot and switch to picasso when the cirrusfb module is loaded?

My exact amiboot line is:

1> amiboot -k vmlinuz video=cirrusfb:640x480

Thanks!

Hm, im out of ideas, you could try 2.8.28, i uploaded it to aminet a
few days ago, but something tells me that wont make any difference. If
that doesnt work, try 2.4, and if that works, holler.
