FlushResp

// Constructor
SST::Interfaces::StandardMem::FlushResp(id_t id, Addr pAddr, uint64_t size, flags_t flags = 0,
    Addr vAddr = 0, Addr iPtr = 0, uint32_t tid = 0);
SST::Interfaces::StandardMem::FlushResp(FlushAddr* fl, flags_t newFlags = 0);

Response Type None  
Needs Response false  
Corresponding request types StandardMem::FlushAddr

The StandardMem::FlushResp request class defines a response to a cache flush (SST::StandardMem::Request::FlushAddr). The id, pAddr, vAddr, size, flags and tid fields are copied from the corresponding Flush request. In some memory system implementations, flushes can fail. As such, a FlushResp may have the F_FAIL flag set on it and the endpoint would need to handle that case appropriately. In the constructor above, the newFlags field is added to the existing set of flags copied from the flush request (flushEv).

Member variables​

Including those inherited from the StandardMem::Request base class, StandardMem::FlushResp includes the following member variables.

  • id (id_t) A request or response identifier. This id matches that of the corresponding flush request.
  • flags (flags_t) A 32-bit vector indicating any special flags added to the request
  • pAddr (Addr) The physical byte address for the line being flushed
  • vAddr (Addr) The virtual (if any) address for the line being flushed
  • size (uint64_t) The number of bytes to flush
  • iPtr (Addr) An instruction pointer. This is optional metadata.
  • tid (uint32_t) An optional thread ID, can be used by memory systems if needed

makeResponse​

Request* makeResponse();

Returns nullptr.

needsResponse​

bool needsResponse();
