** Description changed: Could we have basic profiling & tracing options enabled in Linaro - vexpress kernel? I'd suggest: + kernel? I'd suggest: + CONFIG_HIGH_RES_TIMERS=y (for using hrtimers as a sampling clock) + CONFIG_LOCAL_TIMERS=y (for A9 targets, otherwise hrtimers don't work) CONFIG_PROFILING=y CONFIG_PERF_EVENTS=y CONFIG_HW_PERF_EVENTS=y CONFIG_FTRACE=y - CONFIG_ENABLE_DEFAULT_TRACERS=y - CONFIG_HIGH_RES_TIMERS=y - - (the last one allows using hrtimers as a sampling clock) + CONFIG_TRACING=y and/or CONFIG_GENERIC_TRACER=y (enabled by any tracer, eg. when ENABLE_DEFAULT_TRACERS=y)
