From 8615b27174ae06db4665016c877b1e88031af203 Mon Sep 17 00:00:00 2001 From: Mitch Hayenga Date: Tue, 5 Apr 2016 12:39:21 -0500 Subject: mem: Remove threadId from memory request class In general, the ThreadID parameter is unnecessary in the memory system as the ContextID is what is used for the purposes of locks/wakeups. Since we allocate sequential ContextIDs for each thread on MT-enabled CPUs, ThreadID is unnecessary as the CPUs can identify the requesting thread through sideband info (SenderState / LSQ entries) or ContextID offset from the base ContextID for a cpu. --- src/cpu/trace/trace_cpu.cc | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'src/cpu/trace/trace_cpu.cc') diff --git a/src/cpu/trace/trace_cpu.cc b/src/cpu/trace/trace_cpu.cc index d6aa9aaeb..e81a79818 100644 --- a/src/cpu/trace/trace_cpu.cc +++ b/src/cpu/trace/trace_cpu.cc @@ -627,7 +627,7 @@ TraceCPU::ElasticDataGen::executeMemReq(GraphNode* node_ptr) // Create a request and the packet containing request Request* req = new Request(node_ptr->physAddr, node_ptr->size, node_ptr->flags, masterID, node_ptr->seqNum, - ContextID(0), ThreadID(0)); + ContextID(0)); req->setPC(node_ptr->pc); // If virtual address is valid, set the asid and virtual address fields // of the request. @@ -1123,7 +1123,7 @@ TraceCPU::FixedRetryGen::send(Addr addr, unsigned size, const MemCmd& cmd, req->setPC(pc); // If this is not done it triggers assert in L1 cache for invalid contextId - req->setThreadContext(ContextID(0), ThreadID(0)); + req->setContext(ContextID(0)); // Embed it in a packet PacketPtr pkt = new Packet(req, cmd); -- cgit v1.2.3
