From bb5c832e51ba6c6fcd6b10f29326d0ab6a8d0697 Mon Sep 17 00:00:00 2001 From: George Gao Date: Mon, 27 Jul 2020 17:54:29 -0700 Subject: [PATCH] asoc: lahaina: use new pm_qos API to let audio ULL run on core 1 and 2 The sound core driver used old pm_qos APIs which does not have CPU afinity mask. As a result, ULL playback runs on all cpu cores. This change uses new API call with affinity to core-1/2.
