[PATCH v5 07/12] cxl: Move QoS class to be calculated from the nearest CPU

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Retrieve the qos_class (QTG ID) using the access coordinates from the
nearest CPU rather than the nearst initiator that may not be a CPU.
This may be the more appropriate number that applications care about.
