From 15084a8e1658ddaea42c7d3a72ccbcec2b85f54c Mon Sep 17 00:00:00 2001 From: Tao Zhou Date: Mon, 10 Jan 2022 15:12:38 +0800 Subject: drm/amd/pm: only send GmiPwrDnControl msg on master die (v3) PMFW only returns 0 on master die and sends NACK back on other dies for the message. v2: only send GmiPwrDnControl msg on master die instead of all dies. v3: remove the pointer check for get_socket_id and get_die_id as they should be present on Aldebaran.
