Subject: [PATCH AUTOSEL 5.10 010/217] drm/amdgpu: change to save bad pages in UMC error interrupt callback
Date: Tue, 22 Dec 2020 21:12:59 -0500	[thread overview]
Message-ID: <20201223021626.2790791-10-sashal@kernel.org> (raw)
In-Reply-To: <20201223021626.2790791-1-sashal@kernel.org>

From: Dennis Li <Dennis.Li@amd.com>

[ Upstream commit 22503d803dab174b7f038fc9886c225ef30ee95c ]

Instead of saving bad pages in amdgpu_ras_reset_gpu, it will reduce
the unnecessary calling of amdgpu_ras_save_bad_pages.
