Member Function Documentation

virtual void BaseTLB::demapPage	(	Addr	vaddr,
		uint64_t	asn
	)

pure virtual

Implemented in ArmISA::TLB, SparcISA::TLB, PowerISA::TLB, GenericTLB, AlphaISA::TLB, MipsISA::TLB, RiscvISA::TLB, and X86ISA::TLB.

virtual void BaseTLB::flushAll ( )

pure virtual

Remove all entries from the TLB.

Implemented in ArmISA::TLB, PowerISA::TLB, SparcISA::TLB, MipsISA::TLB, AlphaISA::TLB, RiscvISA::TLB, and X86ISA::TLB.

Referenced by memInvalidate().

virtual BaseMasterPort* BaseTLB::getMasterPort ( )

inlinevirtual

Get the table walker master port if present.

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.

Returns: A pointer to the walker master port or NULL if not present

Reimplemented in ArmISA::TLB, and X86ISA::TLB.

Definition at line 85 of file tlb.hh.

void BaseTLB::memInvalidate ( )

inlinevirtual

Invalidate the contents of memory buffers.

When the switching to hardware virtualized CPU models, we need to make sure that we don't have any cached state in the system that might become stale when we return. This method is used to flush all such state back to main memory.

This does not cause any dirty state to be written back to memory.

Reimplemented from SimObject.

Definition at line 87 of file tlb.hh.

References flushAll().

virtual void BaseTLB::takeOverFrom ( BaseTLB * otlb )

pure virtual

Take over from an old tlb context.

Implemented in ArmISA::TLB, SparcISA::TLB, PowerISA::TLB, MipsISA::TLB, RiscvISA::TLB, AlphaISA::TLB, and X86ISA::TLB.
