Queue latency test program
# SPDX-License-Identifier: GPL-2.0-or-later
Synopsis
queuelat [-c|--cycles N] [-f|--freq F] [-h|--help] [-m|--max-len LEN] [-p|--packets F] [-q|--queue-len N] [-t|--timeout TIME]
Description
queuelat simulates a network queue checking for latency violations in packet processing.
Options
A summary of options is included below.
- -c, --cycles=N
Estimated number of cycles it takes to process one packet. This value should come from the envisioned packet forwarding application being simulated.
- -f, --freq=F
TSC frequency in MHz.
- -h, --help
Show help
- -m, --max-len=N
Maximum allowed latency, in nanoseconds. If latency to process any packet exceeds this value, the program quits, writing a message to the trace buffer.
- -p, --packets=F
Million packets per second that arrive for processing.
- -q, --queue-len=N
Minimum queue length to print in the trace
- -t, --timeout=TIME
Timeout in seconds to quit the program.
