From 18a0409a6bae5c4df971e8423d2dbc3067354c9b Mon Sep 17 00:00:00 2001 From: yanyan kang Date: Mon, 29 Jul 2019 17:46:44 +0800 Subject: [PATCH 3441/4256] drm/amd/display: audio cannot switch to internal when display turns off MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit [why] disable_az_endpoint has been skipped because dc->debug.az_endpoint_mute_only = true. [how] set dc->debug.az_endpoint_mute_only false when PPLIB’s PME notification function pointer is not NULL at the dcn10_resource construct function,because right now SMU/PPLIB and DAL all have the AZ D3 force PME notification implemented. AZ D3 should work.
