From fa249461caa431b774b558349b32282477ef6153 Mon Sep 17 00:00:00 2001 From: Andreas Sandberg Date: Thu, 2 May 2013 12:02:19 +0200 Subject: [PATCH] kvm: Add checkpoint debug print Add a debug print (when the Checkpoint debug flag is set) on serialize and unserialize. Additionally, dump the KVM state before serializing. The KVM state isn't dumped after unserializing since the state is loaded lazily on the next KVM entry. --- src/cpu/kvm/base.cc | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/src/cpu/kvm/base.cc b/src/cpu/kvm/base.cc index 59553b42c..510d6ae25 100644 --- a/src/cpu/kvm/base.cc +++ b/src/cpu/kvm/base.cc @@ -48,6 +48,7 @@ #include "arch/utility.hh" #include "cpu/kvm/base.hh" +#include "debug/Checkpoint.hh" #include "debug/Kvm.hh" #include "debug/KvmIO.hh" #include "debug/KvmRun.hh" @@ -213,6 +214,11 @@ BaseKvmCPU::regStats() void BaseKvmCPU::serializeThread(std::ostream &os, ThreadID tid) { + if (DTRACE(Checkpoint)) { + DPRINTF(Checkpoint, "KVM: Serializing thread %i:\n", tid); + dump(); + } + // Update the thread context so we have something to serialize. syncThreadContext(); @@ -225,6 +231,8 @@ void BaseKvmCPU::unserializeThread(Checkpoint *cp, const std::string §ion, ThreadID tid) { + DPRINTF(Checkpoint, "KVM: Unserialize thread %i:\n", tid); + assert(tid == 0); assert(_status == Idle); thread->unserialize(cp, section); -- 2.30.2
