New Connection

The new_connection boot method can be used to switch to a new connection. If the kernel and the device are both appropriately configured, a test can use a new connection to isolate test and kernel messages.

If the second connection uart0 is configured in the device dictionary, the connection can be created in a separate namespace.

yaml - boot: namespace: isolation connection: uart0 method: new_connection

The new_connection boot method must use a different namespace to all other actions in the test job. The test actions must pass this namespace label as the connection-namespace.

yaml - test: namespace: hikey-oe connection-namespace: isolation definitions: - from: git repository: https://gitlab.com/lava/functional-tests.git path: posix/smoke-tests-basic.yaml name: smoke-tests timeout: minutes: 5

Example device

  'uart1': 'telnet w1 7008',
  'uart2': 'telnet w1 7009',

{% set connection_tags = {
