Realtime threads
- Scheduling policies
- The scheduling policy associated with SCHED_OTHER is
SCHED_RR.
- Scheduling contention scope
- QNX Neutrino supports the PTHREAD_SCOPE_SYSTEM
scheduling contention scope.
- Default scheduling contention scope
- The default scheduling contention scope is PTHREAD_SCOPE_SYSTEM.
- Scheduling allocation domain
- The mechanism to configure the system so that the scheduling allocation
domain has size one, so that the binding of threads to scheduling
allocation domains remains static is as follows:
- For a multiprocessor system, the number of processors enabled is controlled
by the BSP-specific startup program.
- The -P1 command-line argument to the startup program
enables only one processor, creating a scheduling allocation domain
of size one.
