Learn how secure boot faults are tracked and managed in CXL memory modules from initial detection through host notification and recovery actions. Explore the complete error handling pipeline starting from ROM-level fault detection in OCP-compliant secure boot processes, through logging mechanisms in secure enclaves and SRAM event queues, to standardized reporting formats like CPER for firmware-first error handling. Understand how mutable firmware logs errors to SPI NOR storage and implements standardized signaling mechanisms based on CSP policies aligned with OCP Fault Management specifications. Discover autonomous recovery capabilities of CXL devices, including side-band interface instantiation for host-orchestrated recovery, and examine host-side log retrieval through CXL-defined CCI commands like Get_Log and BDAT table publishing for BMC and OS consumption. Master the use of CPAD format as defined by the OCP Hardware Fault Management RAS API workstream for conveying recovery actions to host systems, providing comprehensive insight into enterprise-grade fault management for CXL memory infrastructure.
