atyfb and radeonfb

[Steven Newbury]

Is atyfb in 2.4 known to work with recent Mach64 chips like Rage XL? 
When I install the driver it detects the chip but results in just a 
black screen.  I also noticed that it detects WRAM, whereas I am certain 
it should be SGRAM.  The XFree86 driver detects everything ok and just 
works.

I have also noticed that the radeonfb driver lacks support for 
initialising the card if the BIOS hasn't already done it.  I have 
recently changed from a matrox setup where the matroxfb driver would 
initialise any matrox cards found irrespective of whether the BIOS 
decided to do it unless it was told not to.  Is there any chance that 
this functionality is going to be added to the radeonfb driver?  In 
2.5/6 perhaps?

I did run a sparc64 with builtin Rage XL for about a year (2.4.18 time),
it worked fine. Don't remember the type of the RAM but it had 8M. At
first I had a problem with pixel clock frequency - the kernel new a
higer value for XL than the sparc64 implemented and so the description
of XL in kernel driver got changed for lower clock. But I doubt this
helps you :(

Well, I don't know if Geert still have much time to maintain
this driver, any help implementing the missing features would
be nice ;)

If you can get ATI to provide POST code for every single ASIC
rev. out there, that may be a good start.

Erhm, not really...

For RAGE XL support, you want to contact Steve Longerbeam <stevel@mvista.com>.

I reverse-engineered ATI's video BIOS on the Xpert98 PCI card (RageXL) using
a PCI bus analyzer. Got atyfb to work on embedded platforms and PC's 
that way.
It could work with other RageXL-based cards with some tweaking. I'll 
give you the
source if you're interested.
