Hi, Sean,

Do you think we can have a quick sync about the re-assess for pKVM on x86?

Thanks

No topic this week. Feel free to come with questions about upstream processes, the status or direction of a particular series, KVM technical details, etc.

Note! The next three instances after this are canceled, as I will either be unavailable or OOO.

--- Begin Message --- 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.
