<abstract>
<para>The purpose of this document is to provide firmware and software
architectural details associated with Error Recovery and Logging on OpenPOWER Systems.
The base content for this document were contributed to the OpenPOWER Foundation in the
<citetitle>IBM Linux on Power Architecture Platform Reference (LoPAPR) Draft</citetitle>
document which detailed Linux running on PowerVM. While this information is not always
immediately applicable to new OpenPOWER modes of bare metal or KVM, many of the
concepts and interfaces remain in some form. Until such time as the document addresses
these new OpenPOWER modes and components, it will remain versioned less than 1.0. It should
also be noted that the original document had numerous contributors inside IBM.</para>
<para>This document is a Standard Track, Work Group Specification work product owned by the
System Software Workgroup and handled in compliance with the requirements outlined in the
<citetitle>OpenPOWER Foundation Work Group (WG) Process</citetitle> document. It was
created using the <citetitle>Master Template Guide</citetitle> version 0.9.5. Comments,
questions, etc. can be submitted to the public mailing list for this document at
