Detailed Description

Memory operation metadata.

This class holds the information about a memory operation. It lives from initiateAcc to resource deallocation at commit or squash. LSQRequest objects are owned by the LQ/SQ Entry in the LSQUnit that holds the operation. In addition, the LSQRequest is a TranslationState, therefore, upon squash, there must be a defined ownership transferal in case the LSQ resources are deallocated before the TLB is done using the TranslationState. If that happens, the LSQRequest will be self-owned, and responsible to detect that its services are no longer required and self-destruct.

Release the LSQRequest.

Notify the sender state that the request it points to is not valid anymore. Understand if the request is orphan (self-managed) and if so, mark it as freed, else destroy it, as this means the end of its life cycle. An LSQRequest is orphan when its resources are released but there is any in-flight translation request to the TLB or access request to the memory.
