18.3.2.2 IA-32 Architecture Corrected Machine Check
Processors implementing the IA-32 Instruction Set Architecture may report corrected processor
errors to OSPM. The information in this table allows platform firmware to communicate key
parameters of the corrected processor error reporting mechanism to OSPM, including whether CMC
processing should be enabled.
Only one entry of this type is permitted in the HEST. OSPM applies the information specified in this
entry to all processors.
