stk::test::spinlock Namespace Reference

Namespace of SpinLock test. More...

Classes
class	MutualExclusionTask
	Tests that Lock()/Unlock() provides mutual exclusion under concurrent access. More...
class	TryLockFreeTask
	Tests TryLock() succeeds immediately when the lock is free. More...
class	TryLockContendedTask
	Tests TryLock() returns false immediately when the lock is held by another task. More...
class	RecursiveLockTask
	Tests recursive Lock()/Unlock() by the same task. More...
class	RecursiveTryLockTask
	Tests TryLock() recursive acquisition by the owning task. More...
class	YieldUnderContentionTask
	Tests that Lock() yields cooperatively when spin count is exhausted. More...
class	UnlockTransferTask
	Tests that Unlock() correctly transfers the lock to a waiting contender. More...
class	StressTestTask
	Stress test mixing Lock() and TryLock() under full five-task contention. More...
