From 972fb53d3605eb6cdf0d6ae9a52e910626a91ff7 Mon Sep 17 00:00:00 2001 From: Guchun Chen Date: Tue, 10 Jan 2023 11:33:44 +0800 Subject: [PATCH] drm/amd/pm/smu13: BACO is supported when it's in BACO state This leverages the logic in smu11. No need to talk to SMU to check BACO enablement as it's in BACO state already.
