radeonfb and dvi support

[Louis Garcia]

Is the radeonfb driver going to have support for the dvi port any time soon.
I'm talking about the 2.4.x kernels.

You have to ask Ani Joshi. I doubt it tho.

PPC -- radeonfb / XFree86 (ati) support for 1280x854-16 with Radeon Mobility M7 LW (new Apple Titanium)?

[Miles Lane]

A few questions:

1)  What is the current state of syncing between benh's kernel
    tree with 2.4 (latest vanilla and ac) and with 2.5 (
    latest vanilla and dj)?  Should the 2.5 kernels have any
    chance of working with the newest Apple Titanium (88MHz)?

2)  Ani, what's the status with XFree86 support?  Should the
    radeonfb driver enable the XFree86 fbdev driver to operate
    at 16 bpp?  Where can I get the latest/best radeonfb code?

3)  What are the pros and cons of using fbdev verses the 
    XFree86 ati driver?

If anyone has new code they'd like me to test, please let me know.

Thanks,
	Miles

You need a newer kernel.

This is from OFfb and thus bogus.

Recent benh kernel or at least 2.4.18.

All cons, no pros really.

The 4.2.0 or later ati/radeon driver should work with Option "UseFBDev"
if you're running radeonfb. You'll have to provide a 1280x854 mode
definition (fbset -x). If you want DRI, you need to get the current DRI
CVS.

If you are running single head (and not the LCD on DVI on the latest
laptops), the one in my tree should work (thanks to Paulus fixes)

My desktop has a radeon 7500 with a flat panel. How can I get a patch
from your tree?

Just pick the entire radeonfb from my rsync

(rsync.penguinppc.org::linux-2.4-benh)

Ben.
