A summary of the discussion around the two primary decisions we are seeking to get resolved are as follows, Topic: DomB: Adoption of Device Tree as the format for the Launch Control Module * Consensus approval from x86 and Arm maintainers and members of the Xen community on the call to proceed with Device Tree as the format for the DomB LCM (described in the previous mailing list posts). - a working group will follow up on the work for handling migration of device tree handling code within the hypervisor, previously imported from outside the project, from the Arm hypervisor code into Common. Topic: DomB: Surfacing configuration data to guests: ACPI tables, Device Tree * Recommendation was that both will be needed, and OK to proceed with just implementing one but plan and design for the second to be added. First is likely to be ACPI; to be determined as development progress is made. To continue the discussion from there, I would like to propose a call on Thursday February 11th at 1700UTC, 0900PST/1200EST/1800CEST. I have provided call details below for those who are able to attend. The agenda is available on CryptPad. If you are not able to attend, please reach out directly. Thanks and hope to see everyone on the call!
