Confirmed topics

Meeting notes 

• Virt CPU hotplug update - Lorenzo
  • [Salil]: suggest a few things for PSCI based implementation
    1. boot time considerations for kernel
    2. resources, like how much data structures in the kernel are costing
    3. any use cases for DT? [Lorenzo] the whole approach should be ACPI and DT agnostic, PSCI solves both
  • Next:
    • open questions around boot time and enumerating
    • follow up call with K8s guys, time TBD
    • some spec work for Arm

• CXL introduction - Jonathan
