template<class T>

TlbEntry::DomainType ArmISA::AbortFault< T >::domain

protected

Definition at line 393 of file faults.hh.

template<class T>

Addr ArmISA::AbortFault< T >::faultAddr

protected

The virtual address the fault occured at.

If 2 stages of translation are being used then this is the intermediate physical address that is the starting point for the second stage of translation.

Definition at line 385 of file faults.hh.

template<class T>

Addr ArmISA::AbortFault< T >::OVAddr

protected

Original virtual address.

If the fault was generated on the second stage of translation then this variable stores the virtual address used in the original stage 1 translation.
