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().
|
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.
Reimplemented in ArmISA::TLB, and X86ISA::TLB.
|
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.

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.
