Re: PCIe Graphic card for SPARC T1000/2000 Platform

[Nasser Shayesteh <Nasser.Shayesteh@Sun.COM>]

David,

Thanks for the input. The platform that I am currently testing is 
T5120/5220. It does not have any PCI slots. It has three PCI-Express 
slots. The Radeon(XVR-100) supported by Sun is a PCI card. I have not 
been able to locate a PCI-Express version of the card. Sun supports a 
different version of Radeon family that is based on [FireGL V3100 (PCIE) 
- RV370 5B64]. It is called XVR-300. it works on T5120 platforms running 
solaris. There is a strong interest to get this card working on T5120 
and the future RDK platforms. it also seems that there is a support for 
this card in the linux under (radeon_base.c). I tried this card a couple 
of times using two different versions of Linux kernel (stock Ubuntu and 
custom built based on source_2.6.24). However, the system hangs during 
boot regardless of output-device= screen or virtual-console. I built a 
new kernel without the Radeon driver and was able to boot. No hard hang 
there. Any inputs appreciated.
