CONFIG_RCU_PERF_TEST: performance tests for RCU

General informations

The Linux kernel configuration item CONFIG_RCU_PERF_TEST has multiple definitions:

performance tests for RCU found in kernel/rcu/Kconfig.debug

The configuration item CONFIG_RCU_PERF_TEST:

• prompt: performance tests for RCU
• type: tristate
• depends on: CONFIG_DEBUG_KERNEL
• defined in kernel/rcu/Kconfig.debug
• found in Linux kernels: 4.13–4.20, 5.0–5.9
• modules built: rcuperf, rcuperf

Help text

This option provides a kernel module that runs performance tests on the RCU infrastructure. The kernel module may be built after the fact on the running kernel to be tested, if desired.

Say Y here if you want RCU performance tests to be built into the kernel. Say M if you want the RCU performance tests to build as a module. Say N if you are unsure.
