[PATCH V1 0/6] Add UEFI 2.6 and ACPI 6.1 updates for RAS on ARM64
Add support for Generic Hardware Error Source (GHES) v2, which introduces the capability for the OS to acknowledge the consumption of the error record generated by the Reliability, Availability and Serviceability (RAS) controller. This eliminates potential race conditions between the OS and the RAS controller. Add support for the timestamp field added to the Generic Error Data Entry v3, allowing the OS to log the time that the error is generated by the firmware, rather than the time the error is consumed. This improves the correctness of event sequences when analyzing error logs. The timestamp is added in ACPI 6.1, reference Table 18-343 Generic Error Data Entry. Add support for ARMv8 Common Platform Error Record (CPER) per UEFI 2.6 specification. ARMv8 specific processor error information is reported as part of the CPER records. This provides more detail on for processor error logs. Synchronous External Abort (SEA) represents a specific processor error condition in ARM systems. A handler is added to recognize SEA errors, and a notifier is added to parse and report the errors before the process is killed. Refer to section N.2.1.1 in the Common Platform Error Record appendix of the UEFI 2.6 specification.
