Subject: [PATCH AUTOSEL 6.1 28/29] drm/amdgpu: Fix call trace warning and hang when removing amdgpu device
Date: Sun, 19 Mar 2023 20:54:10 -0400 [thread overview]
Message-ID: <20230320005413.1428452-28-sashal@kernel.org> (raw)
In-Reply-To: <20230320005413.1428452-1-sashal@kernel.org>
From: lyndonli <Lyndon.Li@amd.com>
[ Upstream commit 93bb18d2a873d2fa9625c8ea927723660a868b95 ]
On GPUs with RAS enabled, below call trace and hang are observed when
shutting down device.
v2: use DRM device unplugged flag instead of shutdown flag as the check to
prevent memory wipe in shutdown stage.
