From e8b6e76f69a4336076a2e639d211c4cf3447ce87 Mon Sep 17 00:00:00 2001 From: Gurchetan Singh Date: Tue, 21 Sep 2021 16:20:19 -0700 Subject: drm/virtio: implement context init: plumb {base_fence_ctx, ring_idx} to virtio_gpu_fence_alloc These were defined in the previous commit. We'll need these parameters when allocating a dma_fence. The use case for this is multiple synchronizations timelines. The maximum number of timelines per 3D instance will be 32. Usually, only 2 are needed -- one for CPU commands, and another for GPU commands. As such, we'll need to specify these parameters when allocating a dma_fence. vgdev->fence_drv.context is the "default" fence context for 2D mode and old userspace.
