finalizePhysical()

Fault TLB::finalizePhysical ( const RequestPtr &  req, ThreadContext *  tc, Mode  mode  ) const

overridevirtual

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

req	Request to updated in-place.
tc	Thread context that created the request.
mode	Request type (read/write/execute).

Returns

A fault on failure, NoFault otherwise.

Implements BaseTLB.

Port * TLB::getTableWalkerPort ( )

overridevirtual

Get the table walker port.

This is used for migrating port connections during a CPU takeOverFrom() call. For architectures that do not have a table walker, NULL is returned, hence the use of a pointer rather than a reference. For ARM this method will always return a valid port pointer.

Returns
