POSIX 1003.1j Test Suite

Positioning

The Open Group Test Suite for the POSIX Advanced Realtime Extensions is known as VSART. It is a standalone test suite covering POSIX 1003.1j - 2000 and any associated Technical Corrigenda. Additionally it provides test coverage for UNIX 03 threads (reader/writer locks) and Advanced Realtime Option Group in UNIX 03.

Functional Areas Tested

The test suite covers the following functional areas in the IEEE POSIX 1003.1j standard.

Memory management

A facility to allow programs to allocate or access different kinds of physical memory that are present in the system, and allow separate application programs to share portions of this memory.

Synchronization

Synchronization primitives that allow multiprocessor applications to achieve the performance benefits of their hardware architecture.

Clocks and Timers

The addition of the Monotonic Clock, the specification of the effects of setting the time of a clock on other timing services, and the addition of functions to support relative or absolute suspension based upon a clock specified by the application.

POSIX Functions Tested

The following new POSIX functions are tested:

posix_typed_mem_open()
posix_mem_offset ()
posix_typed_mem_get_info()
pthread_spin_init()
pthread_spin_destroy()
pthread_spin_lock()
pthread_spin_trylock()
pthread_spin_unlock()
pthread_barrierattr_init()
pthread_barrierattr_destroy()
pthread_barrierattr_getpshared()
pthread_barrierattr_setpshared()
pthread_barrier_init()
pthread_barrier_destroy()
pthread_barrier_wait()
pthread_rwlockattr_init()
pthread_rwlockattr_destroy()
pthread_rwlockattr_getpshared()
pthread_rwlockattr_setpshared()
pthread_rwlock_init()
pthread_rwlock_destroy()
pthread_rwlock_rdlock()
pthread_rwlock_tryrdlock()
pthread_rwlock_timedrdlock()
pthread_rwlock_wrlock()
pthread_rwlock_trywrlock()
pthread_rwlock_timedwrlock()
pthread_rwlock_unlock()
clock_nanosleep()
pthread_condattr_setclock()
pthread_condattr_getclock()

Tests are also performed on existing functions POSIX .1 functions whose behaviour is modified by the advanced realtime functionality.
