SYSTEM, APPARATUS AND METHOD FOR ENABLING FINE-GRAIN QUALITY OF SERVICE OR RATE CONTROL FOR WORK SUBMISSIONS

Abstract:

In one embodiment, a processor comprises: a first configuration register to store quality of service (QoS) information for a process address space identifier (PASID) value associated with a first process; and an execution circuit coupled to the first configuration register, where the execution circuit, in response to a first instruction, is to obtain command data from a first location identified in a source operand of the first instruction, insert the QoS information and the PASID value into the command data, and send a request comprising the command data to a device coupled to the processor, to enable the device to use the QoS information of a plurality of requests to manage sharing between a plurality of processes. Other embodiments are described and claimed.
