Subject: [PATCH] virtio-gpu: Remove stride and layer_stride check for dGPU prime on VM
Date: Wed, 5 Jul 2023 11:56:22 +0800 [thread overview]
Message-ID: <20230705035622.2841499-1-julia.zhang@amd.com> (raw)
Remove stride and layer_stride check in virtio-gpu so that virgl can
send transfer data command with non zero stride to sync up data from
guest to host for dGPU prime on VM.
