[OpenPower-Firmware] How to get hostboot's runtime log?

[Daniel M Crowell]

Hostboot runtime (HBRT) runs under the opal-prd application in Linux
userspace.  All of the traces go into /var/log/opal-prd.log.  On some older
distros they might be in /var/log/syslog (Ubuntu) or /var/log/messages
(Redhat) .

Hi all,

I need help from IBM's guru -
How can I get trace logs from Hostboot runtime?

To get the trace during the boot procedure, I can redirect output to the
console by overriding TRACFCOMP macro, but this trick only works in IPL.
I am trying to debug NVDIMM support and something bad happens during arm
activation, but I have neither error codes nor logs to analysis.

Thanks in advance for any help!
