This doesn't work. We need to have both backward and forward compatibility. IE. New kernels must work with old OPAL and vice-versa. > The kernel changes have been split into 2 parts: (A) Use the unified > PCI slot reset OPAL API - this patchset; (B) Changes to rpaphp.ko to > support PCI slot hotplug via sysfs entries for PowerPC PowerNV platform. I don't think we should be using rpaphp... we should be creating our new backend, there is almost no commonalities between RPA/PAPR and OPAL. > This patchset affects EEH, PCI reset logics, which is used mainly by > VFIO.
