From 7846f59d0dcb36c13e06a3ba8a4c461e646582b6 Mon Sep 17 00:00:00 2001 From: Andreas Sandberg Date: Mon, 3 Jun 2013 13:55:41 +0200 Subject: arch: Create a method to finalize physical addresses in the TLB Some architectures (currently only x86) require some fixing-up of physical addresses after a normal address translation. This is usually to remap devices such as the APIC, but could be used for other memory mapped devices as well. When running the CPU in a using hardware virtualization, we still need to do these address fix-ups before inserting the request into the memory system. This patch moves this patch allows that code to be used by such CPUs without doing full address translations. --- src/arch/arm/tlb.cc | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'src/arch/arm/tlb.cc') diff --git a/src/arch/arm/tlb.cc b/src/arch/arm/tlb.cc index 6b864b980..7a79725e1 100644 --- a/src/arch/arm/tlb.cc +++ b/src/arch/arm/tlb.cc @@ -94,6 +94,12 @@ TLB::translateFunctional(ThreadContext *tc, Addr va, Addr &pa) return true; } +Fault +TLB::finalizePhysical(RequestPtr req, ThreadContext *tc, Mode mode) const +{ + return NoFault; +} + TlbEntry* TLB::lookup(Addr va, uint8_t cid, bool functional) { -- cgit v1.2.3
