Member Data Documentation

◆ m_bDispatchingWaitEvent

bool Thread::StateLevel::m_bDispatchingWaitEvent

Event dispatch at this level was initiated by a WaitQueue wake.

Definition at line 1149 of file Thread.h.

◆ m_bOwnsAlternateSignalStack

bool Thread::StateLevel::m_bOwnsAlternateSignalStack

This event level owns the thread's active alternate signal stack.

Definition at line 1142 of file Thread.h.

Referenced by PerProcessorScheduler::checkEventState(), Thread::cleanStateLevel(), Thread::popState(), Thread::prepareSignalStateForExec(), and Thread::pushState().

◆ m_bTerminalWaitCancelledBeforeBlock

bool Thread::StateLevel::m_bTerminalWaitCancelledBeforeBlock

A terminal cancel unlinked this level's waiter while its owner was still running toward the scheduler sleep transition. Protected by Thread::m_Lock.

Referenced by Thread::cleanStateLevel().

◆ m_DeferredSignalMaskRestore

bool Thread::StateLevel::m_DeferredSignalMaskRestore

Definition at line 1135 of file Thread.h.

◆ m_DispatchedSignalContinuationEpoch

size_t Thread::StateLevel::m_DispatchedSignalContinuationEpoch

Definition at line 1139 of file Thread.h.

◆ m_DispatchedSignalNumber

size_t Thread::StateLevel::m_DispatchedSignalNumber

Kernel-owned metadata for the signal dispatched at this level.

Definition at line 1138 of file Thread.h.

Referenced by Thread::cleanStateLevel(), Thread::getCurrentSignalDelivery(), Thread::prepareSignalStateForExec(), Thread::pushState(), and Thread::setCurrentSignalDelivery().

◆ m_Errno

size_t Thread::StateLevel::m_Errno

Syscall-local state isolated from nested event handlers.

Definition at line 1145 of file Thread.h.

Referenced by Thread::pushState().

◆ m_ExecutionContext

ExecutionContextState Thread::StateLevel::m_ExecutionContext

Logical context scopes belong to the Thread state they interrupted.

Definition at line 1152 of file Thread.h.

Referenced by Thread::cleanStateLevel(), Thread::executionContext(), and Thread::pushState().

◆ m_InhibitMask

SharedPointer<ExtensibleBitmap> Thread::StateLevel::m_InhibitMask

Stack of inhibited Event masks, gets pushed with a new value when an Event handler is run, and popped when one completes.

Note: A '1' here means the event is inhibited, '0' means it can be fired.

Definition at line 1146 of file Thread.h.

◆ m_pAuxillaryStack

VirtualAddressSpace::Stack* Thread::StateLevel::m_pAuxillaryStack

Auxillary stack, to be freed in case the kernel stack is null. This allows kernel mode threads to have stacks freed, as they are left hanging otherwise.

Definition at line 1119 of file Thread.h.

uint64_t Thread::StateLevel::m_SavedSignalMask

Original mask and interruption state for an armed signal-aware wait.

Definition at line 1132 of file Thread.h.
