The document provides Enhanced Machine Check Architecture Gen 2 (EMCA2) RAS feature’s software (BIOS/Firmware, OS) and hardware integration guidance and validation methodologies which are applied in the Intel® Xeon® Processor E7 – v3 based systems (code named Haswell EX). Integration guides in this document contain EMCA2 initialization and runtime procedures including how hardware to log errors and trigger specific SMI to BIOS/SMM handler as firmware first model then how BIOS/firmware reports enhance error logs to system software through Industrial specification ACPI data structure.
The document provides the Memory Address Range Mirroring RAS feature’s software (BIOS/firmware, OS) and hardware integration and validation methodologies which are applied in the Intel® Xeon® Processor E7 – v3 based systems (code named Haswell EX). Integration guides in this document contain Unified Extensible Firmware (UEFI) BIOS and the OS interface setup flows for reporting and configuring mirror memory region during system boot and runtime.
The following article covers Reliability features at a glance.
