From 03994a01961bd0b87cccbf10d6025f0cd3ee0739 Mon Sep 17 00:00:00 2001 From: Liu Ying Date: Thu, 23 Apr 2015 17:40:00 +0800 Subject: MLK-10733 imx: imx6qpsabreauto: Update IPU QoS settings Update IPU QoS settings from 0x007f007f to 0x77177717 according to the SoC team's recommendation. This change should be able to balance AXI ID0/2/3 priority and set AXI ID1 priority relatively lower, which matches the way we use AXI ID0/1/2/3 for IDMAC23(0), regular IDMACs, IDMAC27 and IDMAC28 respectively in kernel. The specific priority values for each AXI ID are supposed to be picked for the sake of an overall good system performance.
