Hi, I have observed that the dpdk-devbind.py is an interactive tool and not quite useful for automated testing in CI/CD. We are planning to create “dpdk-usertools-server” for making it streamlined. The idea is to create a separate application, which provides REST interface to: - Query the current status of devices and drivers - Bind and unbind devices to different drivers
Future extensions will be to make dpdk-pmdinfo.py, cpu_layout.py and dpdk-setup.sh more automation friendly. =================Details of API==================== -Query Status of devices: Fetch the status of all devices or of a given group, supported groups are: network, crypto, event and mempool devices.
