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
