Name | Describe |
---|---|
mce_start | Start of Monarch synchronization. This waits until all CPUs have* entered the exception handler and then determines if any of them* saw a fatal event that requires panic. Then it executes them* in the entry order.* TBD double check parallel CPU hotunplug |
mce_end | Synchronize between CPUs after main scanning loop.* This invokes the bulk of the Monarch processing. |
