By default it is turned off since there are several list RCU users that still need to be converted to pass a lockdep expression. To prevent false-positive splats, we keep it default disabled but once all users are converted, we can remove this config option. config TORTURE_TEST tristate default n config RCU_PERF_TEST tristate "performance tests for RCU" depends on DEBUG_KERNEL select TORTURE_TEST select SRCU select TASKS_RCU default n help 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. config RCU_TORTURE_TEST tristate "torture tests for RCU" depends on DEBUG_KERNEL select TORTURE_TEST select SRCU select TASKS_RCU default n help This option provides a kernel module that runs torture 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 torture tests to be built into the kernel. Say M if you want the RCU torture tests to build as a module. Say N if you are unsure. config RCU_CPU_STALL_TIMEOUT int "RCU CPU stall timeout in seconds" depends on RCU_STALL_COMMON range 3 300 default 21 help If a given RCU grace period extends more than the specified number of seconds, a CPU stall warning is printed. If the RCU grace period persists, additional CPU stall warnings are printed at more widely spaced intervals. config RCU_TRACE bool "Enable tracing for RCU" depends on DEBUG_KERNEL default y if TREE_RCU select TRACE_CLOCK help This option enables additional tracepoints for ftrace-style event tracing. Say Y here if you want to enable RCU tracing Say N if you are unsure. config RCU_EQS_DEBUG bool "Provide debugging asserts for adding NO_HZ support to an arch" depends on DEBUG_KERNEL help This option provides consistency checks in RCU's handling of NO_HZ. These checks have proven quite helpful in detecting bugs in arch-specific NO_HZ code. Say N here if you need ultimate kernel/user switch latencies Say Y if you are unsure endmenu # "RCU Debugging"
