We have multiple Vulkan context types that are awaiting for the addition of the sync object DRM UAPI support to the VirtIO-GPU kernel driver:
1. Venus context 2. Native contexts (virtio-freedreno, virtio-intel, virtio-amdgpu)
Mesa core supports DRM sync object UAPI, providing Vulkan drivers with a generic fencing implementation that we want to utilize.
This patch adds initial sync objects support. It creates fundament for a further fencing improvements. Later on we will want to extend the VirtIO-GPU fencing API with passing fence IDs to host for waiting, it will be a new additional VirtIO-GPU IOCTL and more. Today we have several VirtIO-GPU context drivers in works that require VirtIO-GPU to support sync objects UAPI.
The patch is heavily inspired by the sync object UAPI implementation of the MSM driver.
