Yes, both are part of the same extension. I considered calling the directory "P8" for three reasons:
- POWER8 is the minimal processor that support the crypto extensions
- I measured the throughput and latency of the instructions on POWER8
- The current implementations can be enhanced further for POWER9 and newer
by using arch 3.00 specific instructions which was introduced in POWER9 so we can call the directory of new implementations "P9"
Ok, let's stay with that naming (but I'll consider changing to lowercase "p8", to match other directory names). If it turns out something more fine grained is needed later, files can be mover around then.
