Subject: [PATCH 2/7] drm/amdgpu: move shadow bo validation to VM code
Date: Wed, 26 May 2021 12:10:22 +0200	[thread overview]
Message-ID: <20210526101027.14936-2-nirmoy.das@amd.com> (raw)
In-Reply-To: <20210526101027.14936-1-nirmoy.das@amd.com>

Do the shadow bo validation in the VM code as
VM code knows/owns shadow BOs.
