From 9ca5b8a170d180889bec0424c27fdd2ee84d2d99 Mon Sep 17 00:00:00 2001 From: Likun Gao Date: Tue, 15 Dec 2020 11:32:20 -0500 Subject: drm/amdgpu: add judgement for suspend/resume sequence S0ix only makes sense on APUs since they are part of the platform, so only when the ASIC is APU should set amdgpu_acpi_is_s0ix_supported flag to deal with the related situation.
