From 6ef83c4e19e9ce20a05127eec8a10911cf3516a7 Mon Sep 17 00:00:00 2001 From: Dave Jiang Date: Fri, 8 Mar 2024 14:59:26 -0700 Subject: cxl: Move QoS class to be calculated from the nearest CPU 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. For most cases, access0 and access1 have the same values.
