§SyncObj
A SyncObj is a binding point for the DRM subsystem to attach single-use fences which are signalled when a device task completes. They are typically provided as optional arguments to device-specific command submission IOCTLs. In practice, they are used to implement Vulkan fence objects.
After a submission IOCTL sets a fence into a SyncObj, it may be exported as a sync file
descriptor. This sync file may be epoll()’d for EPOLLIN to implement asynchronous waiting on
multiple events. This file descriptor is also compatible with tokio::io::unix::AsyncFd for
Rust async/await integration.
