Description

Enable or disable the LMCE feature. This is an extension of the MCA Recovery mechanism providing the capability to deliver Uncorrected Recoverable (UCR) Software Recoverable Action Required (SRAR) errors to one or more specific logical processor threads receiving previously poisoned or corrupted data. When enabled, the UCR SRAR Machine Check Exception is delivered only to the affected thread rather than broadcast to all threads in the system. The feature supports Operating System recovery for cases of multiple,recoverable faults detected in close proximity which would otherwise result in a fatal machine check event. The feature is available only on Advanced RAS processors.
