There's a statement from IBM here: https://www.ibm.com/blogs/psirt/potential-impact-processors-power-family/ I think you're mostly using pasemi CPUs right? I don't have any information on them, and obviously it's going to be hard to find anyone who might know. You might be best finding a proof of concept somewhere and actually testing it. cheers
