I don't have much understanding of this piece of code. At a high level,
the function is meant to implement the snooping behavior of cache
controllers. The cache controller is snopping on the bus. 'pkt' is the
packet seen on the bus. In case this controller or any higher controller
has the address (for which this packet is meant), then the controller
will invalidate that address.
Running without your changes would be a good idea. It seems to me that you
are creating some packet, and it is not being created properly.

currently I have tried bzip2. I have made some changes but but snoop
packets. I don't think my chnages has impact on snoop packets. It is
worth to try the default code. Can you please tell what does this
pieace of code do?

Well, I understood what you wrote in the first email. The question what is
it that you are trying to execute that results in this error. What
application? Have you made any changes?

sorry what? while debuging I see these statemnets are executed:
cpuSidePort->sendTiming(snoopPkt);
delete snoopPkt->senderState;
delete snoopPkt;
The second "delete" says double free or corruption

Hi,
Consider this statements in cache_impl.hh::handleSnoop()
cpuSidePort->sendTiming(snoopPkt);
if (snoopPkt->memInhibitAsserted()) {
assert(!alreadyResponded);
pkt->assertMemInhibit();
} else {
delete snoopPkt->senderState;
}
if (snoopPkt->sharedAsserted()) {
pkt->assertShared();
}
delete snoopPkt;
I have noticed that when
delete snoopPkt->senderState;
is executed, and then
delete snoopPkt;
I get this error:
*** glibc detected *** /home/mahmood/gem5/build/X86_SE/m5.debug:
double free or corruption (fasttop): 0x0000000002a8a640 ***
Is it a bug or something else. Can someone verify that?
