Integrated reliability, availability, and serviceability state machine for central processing units

Abstract:

Systems and methods for an integrated reliability, availability, and serviceability (RAS) state machine are provided. Handling of RAS events by the Basic Input Output System (BIOS) of an integrated circuit device can result in lost processing time on the processing cores of a multi-core processor resulting from numerous system management interrupts generated by the BIOS. To reduce lost processing time, a dedicated state machine can execute instructions to handle RAS events independently of the BIOS and minimize the number of system management interrupts.
