What's the difference between HandleToFD and ExportSyncFile?
One just gives you an FD for sharing the syncobj itself, the other exports the syncobj state into a sync file and you get to do sync file stuff with it.
A) is for process sharing B) for interop with sync files
i'm still confused, but If I understand it correctly, we have 4 kinds fences now: - amdgpu per-ring sequence numbers - syncobj - HandleToFD for sharing a syncobj (this is not an Android fence) - ExportSyncFile, which is an Android fence
Is that right?
Thanks, Marek
