From 3b415f074dc8c3fdd4e461fa5caa6d6f7f04c4bb Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Thu, 2 Oct 2025 12:42:39 -0500 Subject: [PATCH 1/5] drm/amd: Unify shutdown() callback behavior [Why] The shutdown() callback uses amdgpu_ip_suspend() which doesn't notify drm clients during shutdown. This could lead to hangs. [How] Change amdgpu_pci_shutdown() to call the same sequence as suspend/resume.
