void GenericTLB::demapPage ( Addr  vaddr,
uint64_t  asn 
)

Implements BaseTLB.

Definition at line 69 of file tlb.cc.

References warn.

Fault GenericTLB::finalizePhysical ( RequestPtr  req,
ThreadContext tc,
Mode  mode 
) const

Do post-translation physical address finalization.

This method is used by some architectures that need post-translation massaging of physical addresses. For example, X86 uses this to remap physical addresses in the APIC range to a range of physical memory not normally available to real x86 implementations.

Parameters
reqRequest to updated in-place.
tcThread context that created the request.
modeRequest type (read/write/execute).
Returns
A fault on failure, NoFault otherwise.

Definition at line 63 of file tlb.cc.

References NoFault.
