    • actualGeneration

      private static long actualGeneration
      This is the generation of the recorded tasks. The bottom 8 bits [0-7] are reserved for opcode packing. Bit 9 [8] is used for detecting if PerfMark is enabled or not. Bit 10 [9] is unused. Bits 11-64 [10-647] are used for storing the time since Perfmark Was last / enabled or disabled. The units are in nanoseconds/1024, or (inaccurately) called mibros (like micros, but power of 2 based).
