wired_srvthreads_opt Struct Reference

Fan-out policy: per-worker CPU pinning, optional control-thread pinning, the srvrun knobs copied to every worker, and an optional shared AF_XDP config selecting multi-queue mode. More...

#include <srvthreads.h>

Data Fields
int	cores [WIRED_SRVTHREADS_MAX]
	CPU index for worker i.
int	n_cores
	number of workers, <= WIRED_SRVTHREADS_MAX
int	control_core
	CPU to pin the control thread to; -1 = don't pin.
wired_srvrun_opt	run
	busy_poll etc., copied to every worker (no_signal_handlers is forced to 1 regardless of what is passed here: only the control thread installs signal handlers)
const wired_srvxdp_cfg *	xdp
	0 = UDP + SO_REUSEPORT mode (every worker binds its own socket on port via wired_srvrun_serve_env's existing listen path).

Detailed Description

Fan-out policy: per-worker CPU pinning, optional control-thread pinning, the srvrun knobs copied to every worker, and an optional shared AF_XDP config selecting multi-queue mode.

Field Documentation

xdp

const wired_srvxdp_cfg* wired_srvthreads_opt::xdp

0 = UDP + SO_REUSEPORT mode (every worker binds its own socket on port via wired_srvrun_serve_env's existing listen path).

Non-0 = AF_XDP multi-queue mode: worker i opens queue i (wired_srvxdp_open_shared) against one shared per-interface BPF object the control thread owns (wired_srvxdpbpf_open/close).
