I see. Instead of marking the UNSUPPORTED case as fail, you would like to see it as skip. The following is the output with this patch. So I think you don't want to see the "Bail out!" at the end. I will make the change and send v2. ./set-timer-lat Setting timers for every 1 seconds CLOCK_REALTIME ABSTIME PERIODIC timer fired early: 0 : [OK] CLOCK_REALTIME ABSTIME PERIODIC max latency: 479361 ns : [OK] CLOCK_REALTIME RELTIME PERIODIC timer fired early: 0 : [OK] CLOCK_REALTIME RELTIME PERIODIC max latency: 210625 ns : [OK] CLOCK_REALTIME ABSTIME ONE-SHOT timer fired early: 0 : [OK] CLOCK_REALTIME ABSTIME ONE-SHOT max latency: 152892 ns : [OK] CLOCK_REALTIME ABSTIME ONE-SHOT count: 1 : [OK] CLOCK_REALTIME RELTIME ONE-SHOT timer fired early: 0 : [OK] CLOCK_REALTIME RELTIME ONE-SHOT max latency: 167839 ns : [OK] CLOCK_REALTIME RELTIME ONE-SHOT count: 1 : [OK] CLOCK_MONOTONIC ABSTIME PERIODIC timer fired early: 0 : [OK] CLOCK_MONOTONIC ABSTIME PERIODIC max latency: 190204 ns : [OK] CLOCK_MONOTONIC RELTIME PERIODIC timer fired early: 0 : [OK] CLOCK_MONOTONIC RELTIME PERIODIC max latency: 212418 ns : [OK] CLOCK_MONOTONIC ABSTIME ONE-SHOT timer fired early: 0 : [OK] CLOCK_MONOTONIC ABSTIME ONE-SHOT max latency: 158816 ns : [OK] CLOCK_MONOTONIC ABSTIME ONE-SHOT count: 1 : [OK] CLOCK_MONOTONIC RELTIME ONE-SHOT timer fired early: 0 : [OK] CLOCK_MONOTONIC RELTIME ONE-SHOT max latency: 172362 ns : [OK] CLOCK_MONOTONIC RELTIME ONE-SHOT count: 1 : [OK] CLOCK_BOOTTIME ABSTIME PERIODIC timer fired early: 0 : [OK] CLOCK_BOOTTIME ABSTIME PERIODIC max latency: 180767 ns : [OK] CLOCK_BOOTTIME RELTIME PERIODIC timer fired early: 0 : [OK] CLOCK_BOOTTIME RELTIME PERIODIC max latency: 202772 ns : [OK] CLOCK_BOOTTIME ABSTIME ONE-SHOT timer fired early: 0 : [OK] CLOCK_BOOTTIME ABSTIME ONE-SHOT max latency: 117733 ns : [OK] CLOCK_BOOTTIME ABSTIME ONE-SHOT count: 1 : [OK] CLOCK_BOOTTIME RELTIME ONE-SHOT timer fired early: 0 : [OK] CLOCK_BOOTTIME RELTIME ONE-SHOT max latency: 171882 ns : [OK] CLOCK_BOOTTIME RELTIME ONE-SHOT count: 1 : [OK] CLOCK_REALTIME_ALARM ABSTIME missing CAP_WAKE_ALARM? : [UNSUPPORTED] CLOCK_REALTIME_ALARM RELTIME missing CAP_WAKE_ALARM? : [UNSUPPORTED] CLOCK_REALTIME_ALARM ABSTIME missing CAP_WAKE_ALARM? : [UNSUPPORTED] CLOCK_REALTIME_ALARM RELTIME missing CAP_WAKE_ALARM? : [UNSUPPORTED] CLOCK_BOOTTIME_ALARM ABSTIME missing CAP_WAKE_ALARM? : [UNSUPPORTED] CLOCK_BOOTTIME_ALARM RELTIME missing CAP_WAKE_ALARM? : [UNSUPPORTED] CLOCK_BOOTTIME_ALARM ABSTIME missing CAP_WAKE_ALARM? : [UNSUPPORTED] CLOCK_BOOTTIME_ALARM RELTIME missing CAP_WAKE_ALARM? : [UNSUPPORTED] CLOCK_TAI ABSTIME PERIODIC timer fired early: 0 : [OK] CLOCK_TAI ABSTIME PERIODIC max latency: 183220 ns : [OK] CLOCK_TAI RELTIME PERIODIC timer fired early: 0 : [OK] CLOCK_TAI RELTIME PERIODIC max latency: 201380 ns : [OK] CLOCK_TAI ABSTIME ONE-SHOT timer fired early: 0 : [OK] CLOCK_TAI ABSTIME ONE-SHOT max latency: 117230 ns : [OK] CLOCK_TAI ABSTIME ONE-SHOT count: 1 : [OK] CLOCK_TAI RELTIME ONE-SHOT timer fired early: 0 : [OK] CLOCK_TAI RELTIME ONE-SHOT max latency: 154236 ns : [OK] CLOCK_TAI RELTIME ONE-SHOT count: 1 : [OK] Bail out!
