I am running a stress test on a P9 DD2.1 machine with V100 GPU cards. I
found there are some messages in /sys/firmware/opal/msglog. What does these
msg stand for? Are they hints of some kind of problem?

[445217.407812726,7] NPU6: Found LPARSHORT = 0x0 for BDF = 0x400
[445217.408315717,7] NPU6: Found LPARSHORT = 0x2 for BDF = 0x600
[445217.408812085,7] NPU6: Found LPARSHORT = 0x1 for BDF = 0x500

There are 6 GPU cards on the node. But I only ran test on the first 3 GPU

I found this seems to be reported by Skiboot. So I asked in this mailing
list. If this is not the right place, please also help to tell me the right
place or person to get help from. Thank you.

Best Regards!
