From: Mitch Hayenga Date: Tue, 5 Apr 2016 17:39:21 +0000 (-0500) Subject: mem: Remove threadId from memory request class X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8615b27174ae06db4665016c877b1e88031af203;p=gem5.git 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. --- diff --git a/ext/sst/ExtMaster.cc b/ext/sst/ExtMaster.cc index 26a6c4a09..ce6f8ab7b 100644 --- a/ext/sst/ExtMaster.cc +++ b/ext/sst/ExtMaster.cc @@ -177,7 +177,7 @@ ExtMaster::handleEvent(SST::Event* event) } auto req = new Request(ev->getAddr(), ev->getSize(), flags, 0); - req->setThreadContext(ev->getGroupId(), 0); + req->setContext(ev->getGroupId()); auto pkt = new Packet(req, cmdO); pkt->allocate(); diff --git a/src/arch/arm/isa.cc b/src/arch/arm/isa.cc index 6f66e5ae1..d3286a6b0 100644 --- a/src/arch/arm/isa.cc +++ b/src/arch/arm/isa.cc @@ -1521,8 +1521,7 @@ ISA::setMiscReg(int misc_reg, const MiscReg &val, ThreadContext *tc) // with unexpected atomic snoop requests. warn("Translating via MISCREG(%d) in functional mode!
