1 # Redfish resource supplement for Platform Firmware Resilience (PFR)
11 The platform is a collection of fundamental hardware and firmware components
12 needed to boot and operate a system. The Platform Firmware Resiliency(PFR) in
14 resiliency of platform firmware and data against potentially destructive
21 represent the PFR provisioning status such as platform firmware is provisioned
27 Platform Firmware Resilience technology in NIST SP 800-93 provide common
31 resiliency by protecting, detecting and recovering platform assets. Management
32 controller running on server platform can be used to indicate the status of
43 - BMC shall provide the way to represent Platform Firmware Resilience
46 - Event logs should be logged to redfish for Platform Firmware Resilience.
50 Different OEM's has there own way of implementing the Platform Firmware
53 Processors, Trusted Platform Modules(TPM), PSU's, Memory etc... For example
54 Intel uses the "Intel PFR" design to resiliency platform components.
57 Platform Firmware Resilience. It covers only generic redfish ComputerSystem OEM
64 Platform Firmware Resilience but it provides OEM objects for
67 Below are property is defined to represent the Platform Firmware Resilience
71   of platform firmware. It is of Enum Type with below values.
73   1. NotProvisioned: Indicates platform firmware is not provisioned. This is an
76   2. ProvisionedButNotLocked: Indicates that the platform firmware is
79   3. ProvisionedAndLocked: Indicates that the platform firmware is provisioned
82 PFR enabled platforms can provision or re-provision the platform resilience
84 states. But once the platform is transitioned to "ProvisionedAndLocked" state,
100 1. Platform Firmware Resiliency Errors: This is used to log the platform
117 2. Platform Firmware Panic reason: This is used to log the reason for platform
132 3. Platform Firmware Recovery reasons: This is used to log the reason for last
133    platform firmware component recovery.
