Subject: [PATCH v3 06/12] drm/virtio: implement context init: track {ring_idx, emit_fence_info} in virtio_gpu_fence
Date: Tue, 21 Sep 2021 16:20:18 -0700	[thread overview]
Message-ID: <20210921232024.817-7-gurchetansingh@chromium.org> (raw)
In-Reply-To: <20210921232024.817-1-gurchetansingh@chromium.org>

Each fence should be associated with a [fence ID, fence_context,
seqno].  The seqno number is just the fence id.

To get the fence context, we add the ring_idx to the 3D context's
base_fence_ctx.  The ring_idx is between 0 and 31, inclusive.

Each 3D context will have it's own base_fence_ctx. The ring_idx will
be emitted to host userspace, when emit_fence_info is true.
