Subject: [PATCH 2/2] drm/amdgpu: record non-zero error counter info in NBIO before resetting GPU
Date: Fri, 14 Feb 2020 22:06:50 +0800	[thread overview]
Message-ID: <20200214140650.2133-2-guchun.chen@amd.com> (raw)
In-Reply-To: <20200214140650.2133-1-guchun.chen@amd.com>

When NBIO's RAS error happens, before trigging GPU reset, it's needed
to record error counter information, which can correct the error counter
value missed issue when reading from debugfs.
