From c19656cd951a822c0b0f23c91fde08cf313a52ed Mon Sep 17 00:00:00 2001 From: YiPeng Chai Date: Fri, 12 Aug 2022 13:38:34 +0800 Subject: [PATCH] drm/amdgpu: Move psp_xgmi_terminate call from amdgpu_xgmi_remove_device to psp_hw_fini [ Upstream commit 9d705d7741ae70764f3d6d87e67fad3b5c30ffd0 ] V1: The amdgpu_xgmi_remove_device function will send unload command to psp through psp ring to terminate xgmi, but psp ring has been destroyed in psp_hw_fini. V2: 1. Change the commit title. 2. Restore amdgpu_xgmi_remove_device to its original calling location. Move psp_xgmi_terminate call from amdgpu_xgmi_remove_device to psp_hw_fini.
