From c75ff71139d6358678835cca63e35d1135eaf466 Mon Sep 17 00:00:00 2001 From: Mitch Hayenga Date: Thu, 7 Apr 2016 09:30:20 -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. This is a re-spin of 20264eb after the revert (bd1c6789) and includes some fixes of that commit. --- src/mem/cache/prefetch/queued.cc | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'src/mem/cache/prefetch') diff --git a/src/mem/cache/prefetch/queued.cc b/src/mem/cache/prefetch/queued.cc index 03ca3188f..4bc75acd6 100644 --- a/src/mem/cache/prefetch/queued.cc +++ b/src/mem/cache/prefetch/queued.cc @@ -122,8 +122,7 @@ QueuedPrefetcher::notify(const PacketPtr &pkt) pf_pkt->allocate(); if (pkt->req->hasContextId()) { - pf_req->setThreadContext(pkt->req->contextId(), - pkt->req->threadId()); + pf_req->setContext(pkt->req->contextId()); } if (tagPrefetch && pkt->req->hasPC()) { -- cgit v1.2.3
