I don't immediately see why this should depend on a P8 configuration. The driver runs on a BMC, after all. My understanding is that a BMC can be of any architecture. Is there a guarantee that there are and never will be any x86 BMCs, and/or that BMCs are limited to a certain subset of architectures ?
Thanks, Guenter
