Add zkey / paes support for the ZFS filesystem encryption

Canonical/Ubuntu is exploring using ZFS native encryption (without LUKS) when deploying on the ZFS Linux filesystem. ZFS is already available on Ubuntu Server for s390x. Currently with LUKS on s390x installers default to using zkey/paes if availab...

Crypto Hardware Adjunct Processor Assignment

Crypto Adjunct Processors (APs) are assigned to Crypto PCHIDs at Power-on Reset time. In our experience they differ across multiple z15s despite being identical in hardware configuration. Can we manually assign APs to PCHIDs even if it requires a ...
