Subject: [PATCH v2 1/2] drm/amdkfd: handle svm migrate init error
Date: Tue, 21 Sep 2021 14:53:06 -0400	[thread overview]
Message-ID: <20210921185307.25811-1-Philip.Yang@amd.com> (raw)

If svm migration init failed to create pgmap for device memory, set
pgmap type to 0 to disable device SVM support capability.
