Functions

• void SystemLockValidationError (AcquiredLockEntry * lock_entry, AcquiredLockEntry * conflicting_entry, ThreadLockState * state, void * caller_address, void * caller_frame, LockResult result)

  System-defined hook to report detected lock validation failures.

  Defined at line 44 of file ../../zircon/system/ulib/lockdep/test/lock_dep_test.cc

• void SystemLockValidationFatal (AcquiredLockEntry * lock_entry, ThreadLockState * state, void * caller_address, void * caller_frame, LockResult result)

  System-defined hook to abort the program due to a fatal lock violation.

  Defined at line 49 of file ../../zircon/system/ulib/lockdep/test/lock_dep_test.cc

• void SystemCircularLockDependencyDetected (ValidatorLockClassState * connected_set_root)

  System-defined hook to report detection of a circular lock dependency.

• ThreadLockState * SystemGetThreadLockState (LockFlags lock_flags)

  Default implementation of the runtime functions supporting the thread-local

  ThreadLockState. These MUST be overridden in environments that do not support

  the C++ thread_local TLS mechanism.

  Defined at line 21 of file ../../zircon/system/ulib/lockdep/lock_dep.cc

• void SystemInitThreadLockState (ThreadLockState * state)

  System-defined hook that initializes the ThreadLockState for the current thread.

  Defined at line 26 of file ../../zircon/system/ulib/lockdep/lock_dep.cc

• void SystemCircularLockDependencyDetected (LockClassState * connected_set_root)

  Defined at line 53 of file ../../zircon/system/ulib/lockdep/test/lock_dep_test.cc

• LockFlags operator| (LockFlags a, LockFlags b)

  Prevent implicit conversion to int of bitwise-or expressions involving

  LockFlags.

  Defined at line 54 of file ../../zircon/system/ulib/lockdep/include/lockdep/lock_traits.h

• void SystemTriggerLoopDetection ()

  System-defined hook that triggers a loop detection pass. In response to this

  event the implementation must trigger a call lockdep::LoopDetectionPass() on

  a separate, dedicated or non-reentrant worker thread. Non-reentrancy is a

  hard requirement as lockdep::LoopDetectionPass() mutates non-thread safe

  state. An implementation may add hysteresis to prevent too many passes in a

  given time interval.

  Defined at line 57 of file ../../zircon/system/ulib/lockdep/test/lock_dep_test.cc

• LockFlags operator& (LockFlags a, LockFlags b)

  Prevent implicit conversion to int of bitwise-and expressions involving

  LockFlags.

  Defined at line 61 of file ../../zircon/system/ulib/lockdep/include/lockdep/lock_traits.h

• template <typename Lockable, typename Option = void>

  void AssertHeld (const Lockable & lock)

  Assert that the given lock is exclusively held by the current thread.

  Can be used both for runtime debugging checks, and also to help when

  thread safety analysis can't prove you are holding a lock. The underlying

  lock implementation may optimize away asserts in release builds.

  Calling this function requires that LockType has a policy implementing

  `AssertHeld`. The default policy automatically implements AssertHeld

  if the underlying lock object has an `AssertHeld` method.

  Defined at line 93 of file ../../zircon/system/ulib/lockdep/include/lockdep/guard.h

• const char * ToString (LockResult result)

  Returns a string representation of the given LockResult.

  Defined at line 146 of file ../../zircon/system/ulib/lockdep/include/lockdep/common.h

• void AssertNoLocksHeld ()

  Generates a fatal system report if the current thread holds any tracked locks.

  Defined at line 272 of file ../../zircon/system/ulib/lockdep/include/lockdep/thread_lock_state.h

• void LoopDetectionPass ()

  Runs a loop detection pass to find circular lock dependencies. This must be

  invoked at some point in the future after the lock validator calls the

  system-defined SystemTriggerLoopDetection().

  Defined at line 421 of file ../../zircon/system/ulib/lockdep/include/lockdep/lock_class_state.h

• ThreadLockState * SystemGetThreadLockState ()
