Description: Core Scheduling for SMT
More info: This option permits Core Scheduling, a means of coordinated task selection across SMT siblings. When enabled -- see prctl(PR_SCHED_CORE) -- task selection ensures that all SMT siblings will execute a task from the same 'core group', forcing idle when no matching task is found. Use of this feature includes: - mitigation of some (not all) SMT side channels; - limiting SMT interference to improve determinism and/or performance. SCHED_CORE is default disabled. When it is enabled and unused, which is the likely usage by Linux distributions, there should be no measurable impact on performance.
