perf/benchmark: add a new benchmark for seccom_unotify The benchmark is similar to the pipe benchmark. It creates two processes, one is calling syscalls, and another process is handling them via seccomp user notifications. It measures the time required to run a specified number of interations. $ ./perf bench sched seccomp-notify --sync-mode --loop 1000000 # Running 'sched/seccomp-notify' benchmark: # Executed 1000000 system calls Total time: 2.769 [sec] 2.769629 usecs/op 361059 ops/sec $ ./perf bench sched seccomp-notify # Running 'sched/seccomp-notify' benchmark: # Executed 1000000 system calls Total time: 8.571 [sec] 8.571119 usecs/op 116670 ops/sec Signed-off-by: Andrei Vagin <avagin@google.com> Acked-by: "Peter Zijlstra (Intel)" <peterz@infradead.org> Link: https://lore.kernel.org/r/20230308073201.3102738-7-avagin@google.com Link: https://lore.kernel.org/r/20230630051953.454638-1-avagin@gmail.com [kees: Added PRIu64 format string] Signed-off-by: Kees Cook <keescook@chromium.org>
