Re: X works somewhat on DFP with latest radeonfb.c

Hi Ani,

Ben mentioned below that you might have some patches to handle BigEndian
issues for radeon.

Any help would be greatly appreciated.

Thanks,

Kevin

Hi Ben,

Thought you might like to know.  I took a look at the XF410
radeon_driver.c and compared it to the latest versions of
radeon_driver.c in XFreee86 CVS HEAD and they are quite different.

CVS HEAD has a *lot* more support for DFP but since I had the radeonfb
working on the DFP I thought what the hell, and started to try to use
XF 4.1.0 radeon_driver.c with only a few small tweaks (ignoring all of
the Flat Panel code which is old and not-working in XF410) with the
UseFBDev Option so all the DFP register stuff is handled by the
radeonfb.c driver.

X actually starts up with depths of 8 and depths of 24 (32bpp), and
works but the colors are all wrong:  too many pinks in the 8 bit
version and seemingly random colors in the 24 depth.

So I am going to try and play around with the pallette setting.
Ask Ani for his patches. I think the engine must be properly configured
for big endian.

Ben.
