e don't have existing utility (e.g. errinjct) to test the patchset. In order
to conduct the test, you need copy over the eeh-debug.c to PowerNV platform
directory and change the makefile accordingly. Please contact me to get the
eeh-debug.c if you want run the test case. After that, you need write P7IOC
registers explicitly to trigger frozen PE or fenced PHB explicitly as the
following example shows. The patchset has been verified on Firebird-L machine
where I have 2 Emulex ethernet card on PHB#6. I keep pinging to one of the
ethernet cards from external and then use following commands to produce frozen
PE or fenced PHB errors. Eventually, the errors can be recovered and the ethernet
card is reachable after temporary connection lost.

There is an error injection framework we can use nowadays, or maybe you can
put this in tools/powerpc ?
