Not sure how I would know -- But with my eiger kit, I got a
cd from amcc that had a patched 2.6.30 or something kernel
in it to support the 460SX. The pci code was basically
subverted by adding a "port->link=1" at the very end of the
link check to always force it to succeed. However this code
never appeared in the public git repositories, so I am not
sure how the 460SX functioned (if it ever did) since the
link check that is in there now can't work on that SOC.
[marri]I don't know what PCI-E devices you use. We use E1000
As a device for testing. Link-up was working before the submission.
There were some changes happened afterwards to the common code
Which seems to affected all 4xx devices. I will try latest code
On our other SoCs.
I took care of that in my patch. Basically it let the
system go to gen-2 speeds and negotiate down.
[marri] Great thx.
