CONFIG_SCHED_CORE: Core Scheduling for SMT

General informations

The Linux kernel configuration item CONFIG_SCHED_CORE:

Help text

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.
