Subject: [PATCH 4/5] drm/virtio: enqueue virtio_gpu_create_context after the first 3D ioctl
Date: Thu, 13 Feb 2020 15:18:04 -0800	[thread overview]
Message-ID: <20200213231805.622-5-gurchetansingh@chromium.org> (raw)
In-Reply-To: <20200213231805.622-1-gurchetansingh@chromium.org>

For old userspace, initialization will still be implicit.

For backwards compatibility, enqueue virtio_gpu_cmd_context_create after
the first 3D ioctl.

v2: staticify virtio_gpu_create_context
