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.

Not really direct perfetto support, but add a way that tracepoints can
be associated with a driver provided callback which can generate
perfetto events using the timestamps collected on the GPU.

This adds a mechanism, loosely inspired by the linux kernel's tracepoint
mechanism, to declare and emit tracepoints. A driver provided callback
is used to emit cmdstream to capture timestamps on the GPU, which are
used to later "render" the emitted tracepoints.
