Constructor & Destructor Documentation

ArmInterruptPin()

ArmInterruptPin::ArmInterruptPin ( Platform *  platform, ThreadContext *  tc, uint32_t  int_num  )

protected

Definition at line 121 of file base_gic.cc.

References fatal_if, and platform.

Member Function Documentation

clear()

virtual void ArmInterruptPin::clear ( )

pure virtual

Clear a signalled interrupt.

Implemented in ArmPPI, and ArmSPI.

Referenced by ArmISA::PMU::clearInterrupt(), and MmioVirtIO::setInterrupts().

num()

uint32_t ArmInterruptPin::num ( ) const

inline

Get interrupt number.

Definition at line 194 of file base_gic.hh.

raise()

virtual void ArmInterruptPin::raise ( )

pure virtual

Signal an interrupt.

Implemented in ArmPPI, and ArmSPI.

Referenced by ArchTimer::counterLimitReached(), ArmISA::PMU::raiseInterrupt(), MmioVirtIO::setInterrupts(), CpuLocalTimer::Timer::timerAtZero(), Gicv3CPUInterface::virtualUpdate(), and CpuLocalTimer::Timer::watchdogAtZero().

setThreadContext()

void ArmInterruptPin::setThreadContext

(

ThreadContext *

tc

)

Set the thread context owning this interrupt.

This method is used to set the thread context for interrupts that are thread/CPU-specific. Only devices that are used in such a context are expected to call this method.

Definition at line 130 of file base_gic.cc.

References panic_if, and threadContext.

targetContext()

ContextID ArmInterruptPin::targetContext ( ) const

protected

Get the target context ID of this interrupt.

Precondition

setThreadContext() must have been called prior to calling this method.

Definition at line 139 of file base_gic.cc.

References ThreadContext::contextId(), panic_if, and threadContext.

Referenced by ArmPPI::clear(), and ArmPPI::raise().

platform

RealView* const ArmInterruptPin::platform

protected

Arm platform to use for interrupt generation.

Definition at line 217 of file base_gic.hh.
