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 On November 17, 2001 11:07, Benjamin Herrenschmidt wrote:

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.
