Attendees

  • Ilias Apalodimas (Linaro)
  • François Ozog (Linaro)
  • Heinrich Shuchardt (Canonical)
  • Vincent Stehlé (Arm)

Agenda

  • Thank you for your contributions to v2.1.0
  • Issues scrub
    • Issue #100: Wrong link to hypervisor extension for RISC-V
    • Issue #84: Firmware Storage: Partition type GUID recommendations
    • Issue #77: Minimum sizes an OS can expect from the firmware
  • Continue the discussion on Minimum Viable Product (MVP)
    • Hardening, ethernet / CI, ESRT, SCMI, secure flash...

Notes

  • Linaro connect
    • There will be topics about EFI, U-Boot...
  • Arm SystemReady IR workshop in Sophia-Antipolis (in France, the week of Feb 6)
  • Issues scrub
    • Closing Issue #84 ("Firmware Storage: Partition type GUID recommendations")
    • Will likely close Issue #77 ("Minimum sizes an OS can expect from the firmware")
    • Issue #100 simple to fix
  • MVP
    • Firmware handover protocol; hard to specify at EBBR level.
    • Trusted services; part of PSA level 3 (to be verified)? FF-A (on Arm) and handoff
      • Do not require FF-A but rather add conditional requirements for when it is implemented
      • Context: SOAFEE; leverage FF-A from BL33 and handoff. Start hypervisor from TF-A directly.
    • Gone through: TPM, ramdisk, hardening, ethernet
