If your system includes the adaptive partitioning scheduler module, the data for these events includes the partition ID and scheduling flags (e.g. AP_SCHED_BILL_AS_CRIT). For more information, see the Adaptive Partitioning User's Guide.
For more information about thread states, see "Thread life cycle" in the QNX Neutrino Microkernel chapter of the System Architecture guide.
