[ANNOUNCE] PUCK Notes - 2023.06.07 - pKVM on x86

[Sean Christopherson]

Apologies for the slow update, I was waiting for the recording to become
available and was OOO Th/F last week.

Key Takeaways:
 - Primary use case is to secure workloads that process/handle sensitive
   biometric data (e.g. fingerprints, face authentication).
 - SEAM is a poor fit as it doesn't provide mechanisms to restrict access to
   non-DRAM "memory", e.g. access to the hardware devices that provide biometric
   data.  And there's no line of sight to an AMD equivalent.
 - pKVM support requires few changes outside of KVM (though the changes to KVM
   are extensive).

Next Steps:
 - Re-assess in 3-4 weeks after people have had a chance to read through and
   review the RFC patches.
