setup

virtual void setup();

See setup() for a description of SST's setup phase and the use of this function. The (Sub)Component that loaded a StandardMem interface should call this function during its own setup() function. A StandardMem interface may implement this function if needed, but it is not required.

Requirements​

Memory interface  
This function may be optionally implemented.

Endpoint  
Call setup() on the interface during the setup() phase as SST does not automatically call this function on SubComponents.

Parameters​

  • returns none

Examples​

Example 1: Implementing setup() in StandardMem​

Excerpt from sst-elements/src/sst/elements/memHierarchy/standardInterface.cc
void StandardInterface::setup() { 
    /* Report some debug information about the interface setup */
    debug.debug(_L9_, "%s, INFO: Line size: %" PRIu64 ", Mask: 0x%" PRIx64 "\n", getName().c_str(), lineSize_, baseAddrMask_);
    if (noncacheableRegions.empty()) {
        debug.debug(_L9_, "%s, INFO: No noncacheable regions discovered\n", getName().c_str());
    } else {
        std::ostringstream regstr;
        regstr << getName() << ", INFO: Discovered noncacheable regions:";
        for (std::multimap<Addr, MemRegion>::iterator it = noncacheableRegions.begin(); it != noncacheableRegions.end(); it++) {
            regstr << " [" << it->second.toString() << "]";
        }
        debug.debug(_L9_, "%s\n", regstr.str().c_str());
    }
    /* Call setup() on SubComponents */
    link_->setup();
}

Example 2: Supporting setup() at an endpoint​

void Endpoint::setup() 
{
    mem_iface->setup();
}
#include <sst/core/interfaces/stdMem.h>
