lisa.wlgen.rta.Step#

class lisa.wlgen.rta.Step(start_pct=0, end_pct=100, time_s=1, period_ms=100, delay_s=0, loops=1, sched_policy=None, priority=None, cpus=None, uclamp_min=None, uclamp_max=None, numa_nodes_membind=None, **kwargs)[source]#

Bases: RTAPhaseTree

Configure a step load.

This class defines a task which load is a step with a configured initial and final load. Using the loops param, this can be used to create a workload that alternates between two load values.

Parameters:

start_pct (float) – the initial load percentage.
end_pct (float) – the final load percentage.
time_s (float) – the duration in seconds of each load step.
period_ms (float) – the period used to define the load in [ms].

See Phase for the documentation of the following parameters:

cpus
uclamp_min
uclamp_max

Deprecated since version 2.0.

Step is deprecated and will be removed in version 4.0, use lisa.wlgen.rta.DutyCycleSweepPhase instead

Attributes

__reversed__ ^inherited

See collections.abc.Mapping.__reversed__

Properties

`delay_s`
`loops`
`priority`
`sched_policy`
`children` ^inherited	Tree levels are transparent and their children expanded directly in their parent, as long as they have no properties on their own that could change the output of `topo_sort()`. This allows nested `RTAPhaseTree` to act as if it was just a flat node, which is useful since repeated composition with `+` operator will give nested binary trees like that.
`is_empty` ^inherited	`True` if the phase has no content and will result in an empty JSON phase(s).
`phases` ^inherited	Topological sort of the phases in the tree, with the properties merged along each path from the root to the leaves.

Methods

`__init_subclass__()`	Update the docstring used as a `str.format()` template with the following keys:.
`HASH_COERCE()` ^inherited	Used to coerce the values of `self.__dict__` to hashable values.
`__add__()` ^inherited	Compose two phases together by running one after the other.
`__await__()` ^inherited
`__class_getitem__()` ^inherited	See `collections.abc.Iterable.__class_getitem__()`
`__contains__()` ^inherited	See `collections.abc.Mapping.__contains__()`
`__getitem__()` ^inherited	Lookup the value of the given property on that phase.
`__iter__()` ^inherited
`__len__()` ^inherited
`__mul__()` ^inherited	Multiply the phase by `n`, in order to repeat it.
`__rmul__()` ^inherited
`get()` ^inherited	See `collections.abc.Mapping.get()`
`get_rtapp_repr()` ^inherited	rt-app JSON representation of the phase.
`items()` ^inherited	See `collections.abc.Mapping.items()`
`keys()` ^inherited	See `collections.abc.Mapping.keys()`
`split_prop_kwargs()` ^inherited	Split the `kwargs` into two categories:.
`topo_sort()` ^inherited	Topological sort of the tree, and combine the properties along each path from root to leaves at the same time.
`values()` ^inherited	See `collections.abc.Mapping.values()`
`with_delete_props()` ^inherited	Delete all the given property names, equivalent to `with_props(foo=delete())`.
`with_phase_properties()` ^inherited	Return a cloned instance with the properties combined with the given `properties` using `RTAPhaseProperties.__and__()` (`&`). The `properties` parameter is the left operand. If `properties` is `None`, just return the phase itself.
`with_properties_map()` ^inherited	Same as `with_phase_properties()` but with `properties` passed to `RTAPhaseProperties.from_polymorphic()` first.
`with_props()` ^inherited	Same as `with_phase_properties()` but using keyword arguments to set each property. The resulting dictionary is passed to `RTAPhaseProperties.from_polymorphic()` first.

property Step.sched_policy#

property Step.children#

Inherited property, see lisa.wlgen.rta.RTAPhaseTree.children

Tree levels are transparent and their children expanded directly in their parent, as long as they have no properties on their own that could change the output of topo_sort().

property Step.phases#

Inherited property, see lisa.wlgen.rta.RTAPhaseTree.phases

Topological sort of the phases in the tree, with the properties merged along each path from the root to the leaves.
