Subject: [PATCH] drm/amdgpu: fix PSP autoload twice in FLR
Date: Fri, 24 Jul 2020 17:28:54 +0800 [thread overview]
Message-ID: <20200724092854.375664-1-ChengZhe.Liu@amd.com> (raw)
the block->status.hw = false assignment will overwrite PSP's previous
hw status, which will cause PSP execute resume operation after hw init.
