Hello,
I googled some results of amdk8 linuxbios, and seems after dev_enumerate() AMD8111 is not at bus0. So does it mean when we are running from the BIOS ROM the IO HUB must be at bus0, and when we are running in RAM the bus number doesn't matter?
Regards, Liu Tao
In AMD's <<BIOS and Kernel developer's Guide>> 3.3.16 LDTi Bus Number
Registers section it says that if the link contains the HT IO hub the secondary
bus number must be programmed to 0. But amdk8_scan_chains() is called with
max=0, so it won't write the secondary register of any link to 0? Or some
other code handles this case?
