[PATCH 1/4] i386/cpu: Add RAS feature bits on EPYC CPU models

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add the support for following RAS features bits on AMD guests.

SUCCOR: Software uncorrectable error containment and recovery capability.
	The processor supports software containment of uncorrectable errors
	through context synchronizing data poisoning and deferred error
	interrupts.

McaOverflowRecov: MCA overflow recovery support.
