From d63cda5bfcd341b86c07beb5919107aae0d9ba99 Mon Sep 17 00:00:00 2001 From: Xiangliang Yu Date: Tue, 4 Dec 2018 15:13:28 +0800 Subject: [PATCH] drm/amdgpu/psp: Get psp fw version through reading register If PSP FW is running already, driver will not load PSP FW again and skip it. So psp fw version is not correct if reading it from FW binary file, need to get right version from register.
