Regarding the bad-alloc error...
I am creating a new packet with just a new command.
Added the constructor in packet.hh
Packet(MemCmd _cmd)
:cmd(_cmd)
{
}
void setAddr(Packet *pkt,Addr addr)
{
pkt->addr=addr;
flags.set(VALID_ADDR);
}
the new packet is created as
PacketPtr inv_pkt= new Packet(MemCmd::ReqMove);
inv_pkt->setAddr(inv_pkt,temp);
inv_pkt->setDest(-1); //as it is be broadcasted
inv_pkt->setExpressSnoop();
memSidePort->sendTiming(inv_pkt);
//after the work is done in timing access the control comes here
delete inv_pkt;
--
---
but l am getting seg fault after certain time execution when i delete the
packet
can u help me out..y it is so...
