If changing the configuration is not possible, you may fall back to -e itimer profiling mode.
It is similar to CPU mode but does not require perf_events support. As a drawback, there will be no kernel stack traces.
UPDATE: From the discussion email, we see users want this feature could also leverage perf_events if possible, and since async-profiler could also support allocation and wall-clock profiling, we could extend this feature to support more cases.
