IMHO 'not very well' isn't quite fair to ATi. They do cooperate with
the XFree86 folks, as well as offering their own drivers. I'm happily
running a Radeon 7500 low profile PCI card on my micro-ATX Myth
frontend (which uses a LOT less processor power than the video
controller in the SiS chipset).
On a vaguely related note, I'm in the process of designing a new
'open hardware' machine, targeted to run Linux (a successor to the
LART, see .sig). This machine will not have a BIOS, at least not one
in the '20-year IBM legacy' sense; it doesn't even have an x86 CPU.
Trouble is, all current XFree drivers expect the BIOS to initialize
the video chip; the BIOS usually does this by calling a blob of
proprietary x86 code on a ROM chip on the video card. This is what
happened when I approached three major video chip vendors:
NVidia: "We don't support that."
SiliconMotion: "We don't support that."
ATi: "Sure, we can see why you'd want to do that. We'll ask our
engineers to write initialization code for Linux, other customers may
well be interested in that too. If you need something to get your
prototypes tested NOW, you can do <x> to get the card in a working
Additionally, it looks like ATi will allow me to release schematics
of my design without an NDA, which would definitely be out of the
question if I'd use a chip from any of the other major players.
Do you have any horror stories about recent ATi practices (other than
the prime example of wishful thinking engineering that is the
All-In-Wonder) ? Seriously, I'm about to route a PCB with a Radeon on
it, and if there are any major ATi-related gotchas this is the time
I'd want to find out.
