      • Be able to seamlessly run my software stack everywhere.
        • Standards
          • SystemReady SR
            • Solidify QEMU as the reference open source platform.
              • Core PCIe functionality has been added.
          • Server Base Manageability Requirements (SBMR)
            • Make OpenBMC compliant with SMBR 2. Moved to back log for now.
        • Software stack
          • Emulated reference platform
            • Enablement of new platform features in QEMU.
          • BMC
