Re: K8 + 2.4.21 + Tyan S2880

Eric or Ron or Stepfan,

To make the NIC under mem auto-conf code, I have spent one day on it. Here
are my findings:
1. Use the most updated code, in the Etherboot stage it will reboot after
firt NIC try aborting.
2. I have try to subsutite mem-conf with hard code version, and found
another problem, I can not start AP after conherent_ht or memory
initization. Only can start and stop in enable_routing function.
3. I have to move back to old code ( Before Eric moved some definition from
romcc_io.h to arch/io.h and cpu/p6/msr.h). At this situation, if I use
mem-conf, it still can not find broadcom nic in etherboot stage. But after I
substitute mem init with hard code one, It can find the nic.

I will study the difference today.

But anyway what make I can not start AP after conherent_ht or memory init,
so strange ???

Regards

Yinghai Lu

Eric,

It can be compiled with you new code. But it meet problems in Etherboot
stage.
In S2880 has two broadcom NIC port in 8131 bus B, and one amd 8111 built-in
nic, and even if I hide it in amd8111 init and Etherboot can find it and try
to enable it and can not find the PM cap so aborting, in the old linuxbios
code (before yesterday) ( with mem hard code), it will go to tickle on
Broadcom nic, but in the new code (yesterday check in) ( mem configurable),
it will go to MB restarting.???

How about arima broadcom nic position?

All functions are inline and the set of functions called is large.
At least I believe that is the issue.

And good luck catching up....

While I am away you get a chance.  My latest code has changed
sdram_initialize
one more time to take a cpu count parameter.

And perversely this should help because if a function is called in a loop
it will only be inlined once instead of multiple times.
