Detailed Description

Simplified, generic interface to Memory models.

Member Typedef Documentation

template<typename classT , typename dataT = void>
using SST::Interfaces::SimpleMem::Handler = SSTHandler<void, Request*, false, classT, dataT>

Used to create handlers for request handling.

The callback function is expected to be in the form of:

void func(Request* event)

In which case, the class is created with:

new SimpleMem::Handler<classname>(this, &classname::function_name)

Or, to add static data, the callback function is:

void func(Request* event, dataT data)

and the class is created with:

new SimpleMem::Handler<classname, dataT>(this, &classname::function_name, data)

Constructor & Destructor Documentation

SST::Interfaces::SimpleMem::SimpleMem ( SST::ComponentId_t  id,
Params UNUSEDparams 
)
inline

Constructor, designed to be used via 'loadUserSubComponent and loadAnonymousSubComponent'.

Member Function Documentation

virtual Addr SST::Interfaces::SimpleMem::getLineSize ( )
inlinevirtual

Get cache/memory line size from the memory system.

The memory system should provide this and it should be valid after the init() phase is complete, so processors can call this function during setup().

For backward compatibiity, the function returns 0 by default. Eventually, interfaces will be required to implement this function.

Returns
0 if the interface does not provide this capability
line size of the memory system
virtual bool SST::Interfaces::SimpleMem::initialize ( const std::string &  linkName,
HandlerBase handler = nullptr 
)
pure virtual

Second half of building the interface.

Initialize with link name name, and handler, if any

Returns
true if the link was able to be configured.
virtual SST::Event* SST::Interfaces::SimpleMem::recvInitData ( )
inlinevirtual

Receive any data during the init() phase.

See Also
SST::Link::recvInitData()
virtual Request* SST::Interfaces::SimpleMem::recvResponse ( void  )
pure virtual

Receive a Request response from the side of the link.

Use this method for polling-based applications. Register a handler for push-based notification of responses.

Returns
nullptr if nothing is available.
Pointer to a Request response (that should be deleted)
virtual void SST::Interfaces::SimpleMem::sendInitData ( SST::Event ev)
inlinevirtual

Sends a generic Event during the init() phase (Mostly acts as a passthrough)

See Also
SST::Link::sendInitData()
