Hi Jason
Thank you. I look at http://learning.gem5.org/book. but in newer version of
gem5 used ClockedObjectParams (that inherits from SimObjectParamsa) to
define constructor's parameter list.
my problem is that I want to initialize those const params when new object
of class was created. for example:
in older version of gem5, in
src/mem/ruby/network/garnet/flexible-pipeline/GarnetNetwork.cc
was called networkinterface like this:
for (int i=0; i < m_nodes; i++) {
NetworkInterface *ni = new NetworkInterface(i, m_virtual_networks,
this);
ni->addNode(m_toNetQueues[i], m_fromNetQueues[i]);
m_ni_ptr_vector.push_back(ni);
}
but in newer version it was modified to:
for (int i=0; i < m_nodes; i++) {
NetworkInterface *ni = safe_cast<NetworkInterface *>(p->netifs[i]);
m_nis.push_back(ni);
}
now I want to add my new parameter to constructor of NetworkInterface (I added
this parameter) and initialize like older version in GarnetNetwork.cc . how
can I do it>
Thank you.
