SUSE Linux Enterprise Server 11
All CPU side channel mitigations are disabled. This setting gives the highest performance, but least security and should only be used in settings where no untrusted code is used.
mitigations=autoAll CPU side channel mitigations are enabled as they are detected based on the CPU type. The auto-detection handles both unaffected older CPUs and unaffected newly released CPUs and transparently disables mitigations.
This options leave SMT enabled.
mitigations=auto,nosmtThe same as the auto option for mitigations, additionally the symmetric multi-threading of the CPU is disabled if necessary, for instance to mitigate the L1 Terminal Fault side channel issue.
