[LinuxBIOS] New guy in LinuxBios

[Lu, Yinghai]

Comment out several lines about links in resourcemap.c.

 

Current inherent_ht.c already could probe the links automatically...

 

amd/Serengeti_leopard is good model. If you want mptable and irqtable
and acpitable create automatically.

Hello LinuxBios elders,

 

I'm sorry to bother you.

 

I'm begining to study LinuxBios and I have some problem in it.

Hope you can give me some idea.

 

My target board is an AMD Opteron (chipset: K8 / 8111 / 8131) mainboard,

it is similar to Tyan s2880 / s2881 / s2882.

 

So I base on Tyan s2880 to change some config file to compile a
linuxbios.rom,

but it doesn't work.

 

Following is what do I changed in s2880:

1. I changed the payload path in targets/tyan/s2880/Config.lb.

2. modify src/mainboard/tyan/s2880/Config.lb as 42812-pci.txt. ( as
attachment )

    I don't know is it correct that I modified. If you have interest you
can refer to Attachment.

3. generated irq_tables.c by getpir.c and replaced the original one.

 

compile and burn it in rom.

 

After I boot up the target board, it always alert emergency beep.

 

Then, I unmark some debug message in
'src/northbridge/amd/amdk8/raminit.c' to see where is it hang.

The last step is hang on setup_default_resource_map() in
'src/mainboard/tyan/s2880/cache_as_ram_auto.c',

I can see it from serial console ( as attachment again. ) 

 

Is there any configuration I should change, and I didn't do ?

How can I debug it ?

 

Thanks a lot.
