Hi Hui,
I think the SNAT example maybe meet what you want:
snat_in2out_node_fn_inline: (in worker thread)
slow_path
snat_ipfix_logging_nat44_ses_create
vl_api_rpc_call_main_thread
Regards,
Hongjun

Subject: 答复: Re: [vpp-dev] 答复: Re: Signal events between graph nodes within
different threads
Maybe if you could expand on what it is you are trying to achieve?
//when starting worker thread , the main thread can't receive packet from IO,
so we want to transfer some packet to main thread to continue processing.
Is it specifically to do with DHCP (and proxy) or is that just the code you
found that looks like the kind of functionality you believe you need for your
use-case?
// that just looks like our use-case. vlib_process_signal_event called in
worker thread, and signal an event to the dhcp proccess node in main thread.
can vlib_process_signal_event do this?

hi Dave and hongjun:
We also got confused with below code. Dos it works correctly?
Maybe the dhcp_proxy_to_client_input fuction runs in the worker thread, and
it will call vlib_process_signal_event function to trigger dhcp-proccess node
in the main thread.
If it works, maybe the question of mail title could be solved. But We can't
find any other use like this until now.

dhcp_proxy_to_client_input
dhcp_client_for_us
vlib_process_signal_event (vm, dhcp_client_process_node.index,
EVENT_DHCP_CLIENT_WAKEUP, c - dcm-＞clients);
