With little modifications u_trace could be usable for Vulkan drivers. Beside removing dependencies on gallium, the other notable change is the passing of opaque flush_data pointer via u_trace_flush. There is data which becomes available only at this point which other drivers may want to pass. For example Vulkan drivers would want to pass at least submission id (for perfetto) and a sync object to wait on in u_trace_read_ts.
