Quick Start

This mock firmware is designed to be used together with the FBNIC driver QEMU. Visit its Github repo to get started.

How to run

1. Navigate to this directory with cd and start the mock firmware

$ ./mock_fw.py /tmp/fbnic-ctrl-skt

2. Continue your steps in the FBNIC driver QEMU repo

Injecting sensor readings

The mock firmware listens on a Unix socket at /tmp/fbnic-fw-ctl for injection commands. This lets you push firmware-originated events to the driver on demand while the mock firmware is running and a driver is connected.

Currently the only supported injection is sensor readings. Use inject_sensor_value to set the mock firmware’s current temperature (in milli-degrees Celsius) and/or voltage (in millivolts):

$ echo "inject_sensor_value temp 81234 volt 912" | nc -U /tmp/fbnic-fw-ctl

The injected readings become the mock firmware’s current sensor values. If a reading is outside the mock firmware’s healthy range, a SENSOR_THRESHOLD_EXCEEDED event is also sent to the driver for that sensor.
