context - DTS execution context

Runtime contexts.

class LocalContext

Bases: object

Updatable context local to test suites and cases.

lcore_filter_specifier

A number of lcores/cores/sockets to use or a list of lcore ids to use. The default will select one lcore for each of two cores on one socket, in ascending order of core ids.

Type:

framework.testbed_model.cpu.LogicalCoreCount | framework.testbed_model.cpu.LogicalCoreList

ascending_cores

Sort cores in ascending order (lowest to highest IDs). If False, sort in descending order.

Type:

bool

append_prefix_timestamp

If True, will append a timestamp to DPDK file prefix.

Type:

bool

timeout

The timeout used for the SSH channel that is dedicated to this interactive shell. This timeout is for collecting output, so if reading from the buffer and no output is gathered within the timeout, an exception is thrown.

Type:

float

reset() → None

Reset the local context to the default values.

__init__(lcore_filter_specifier: framework.testbed_model.cpu.LogicalCoreCount | framework.testbed_model.cpu.LogicalCoreList = <factory>, ascending_cores: bool = True, append_prefix_timestamp: bool = True, timeout: float = 15) → None

class Context

Bases: object

Runtime context.

__init__(sut_node: ~framework.testbed_model.node.Node, tg_node: ~framework.testbed_model.node.Node, topology: ~framework.testbed_model.topology.Topology, dpdk: DPDKRuntimeEnvironment, tg: TrafficGenerator, local: ~framework.context.LocalContext = <factory>) → None

get_ctx() → Context

Retrieve the current runtime context.

Raises:

InternalError – If there is no context.

init_ctx(ctx: Context) → None

Initialize context.

filter_cores(specifier: framework.testbed_model.cpu.LogicalCoreCount | framework.testbed_model.cpu.LogicalCoreList, ascending_cores: bool | None = None)

Decorates functions that require a temporary update to the lcore specifier.
