Hi,
There seems to be a small problem with BlockingBuffer's squash function. With my
caches configured with mshrs = 1, I get a crash at
m5/mem/cache/miss/blocking_buffer.cc:193. It looks like there isn't always a
miss target. I added a check for this case like so:
void
BlockingBuffer::squash(int thread_number)
{
if (miss.threadNum == thread_number) {
if (miss.hasTargets()) {
MemReqPtr target = miss.getTarget();
miss.popTarget();
assert(target->thread_num == thread_number);
if (target->completionEvent != NULL) {
delete target->completionEvent;
}
target = NULL;
assert(!miss.hasTargets());
miss.ntargets=0;
}
if (!miss.inService) {
miss.deallocate();
cache->clearBlocked(Blocked_NoMSHRs);
cache->clearMasterRequest(Request_MSHR);
}
}
}
This fixes the crash, hopefully in the right way. :)
Regards,
Jos Delbar
