Description
Architected Error Records
With the features such as eMCA, the BIOS
collects error information recorded in
hardware registers in compliance with UEFI
specifications, notifies the OS through the
APEI interface of the ACPI, and locates the
error unit, improving system availability.
Error Injection Support
Implements fault injection to verify RAS
features.
Machine Check Architecture
(MCA)
Provides a software repair function to
rectify uncorrectable errors to improve
system availability.
Enhanced Machine Check
Architecture (eMCA): Gen2
Improves system availability.
OOB access to MCA registers The out-of-band system can access MCA
registers through the PECI. When a fatal
error occurs in the system, the out-of-band
system can collect onsite data to facilitate
subsequent fault analysis and locating and
improve system serviceability.
BIOS Abstraction Layer for
Error Handling
The BIOS processes errors and reports error
information to the OS based on
specifications, improving system
serviceability.
BIOS-based Predictive
Failure Analysis (PFA)
The OS takes the lead. The BIOS provides
information about physical memory error
units. The OS tracks, predicts, and handles
the errors.
