lisa.wlgen.rta.MemWload

class lisa.wlgen.rta.MemWload(size, **kwargs)

Bases: WloadPropertyBase

Workload for the mem event.

Parameters:

size (int) – Size in bytes to be written to the buffer.

Classes

__class__ inherited

Metaclass for properties.

Attributes

KEY	Subclasses can override this attribute so that PropertyBase.from_key() knows that it can call their _from_key() method for that key.
JSON_KEY inherited
OPTIMIZE_JSON_KEYS inherited	Configuration driving the JSON optimization, as a dict(str, set(str)).
REQUIRED_KCONFIG_KEYS inherited	List of KCONFIG keys that need to be =Y on the target kernel for this property to be usable.

Properties

json_value	Value to pass to JSON.
key inherited	Key of the instance.
logger inherited	Convenience short-hand for self.get_logger().
val inherited	Value “payload” of the property.

Methods

__and__()	Combine two instances of the same property together.
to_events()
HASH_COERCE() inherited	Used to coerce the values of self.__dict__ to hashable values.
__add__() inherited	Adding two workloads together concatenates them.
__await__() inherited
__mul__() inherited	Replicate the given workload n times.
__rmul__() inherited
check_kconfig() inherited	Check whether plat_info contains the kernel KCONFIG keys contained in REQUIRED_KCONFIG_KEYS.
find_cls() inherited	Find which subclass can handle key.
from_key() inherited	Alternative constructor that is available with the same signature for all properties.
get_logger() inherited	Provides a logging.Logger named after cls.
log_locals() inherited	Debugging aid: log the local variables of the calling function.
to_default_json() inherited	Similar to to_json() but returns the default values for the keys set in to_json().
to_json() inherited	Snippet of JSON content for that property as Python objects.

MemWload.__class__

alias of PropertyMeta

Attributes

MemWload.KEY = None

Subclasses can override this attribute so that PropertyBase.from_key() knows that it can call their _from_key() method for that key.

Note

This class attribute will not be inherited automatically so that each class can be uniquely identified by its key. Subclass that do not override the value explicitly will get None.

MemWload.JSON_KEY = 'events'

MemWload.OPTIMIZE_JSON_KEYS = {}

Inherited attribute, see lisa.wlgen.rta.ConcretePropertyBase.OPTIMIZE_JSON_KEYS

Configuration driving the JSON optimization, as a dict(str, set(str)).

MemWload.REQUIRED_KCONFIG_KEYS = []

Inherited attribute, see lisa.wlgen.rta.ConcretePropertyBase.REQUIRED_KCONFIG_KEYS

List of KCONFIG keys that need to be =Y on the target kernel for this property to be usable.

Properties

property MemWload.json_value

Value to pass to JSON.

property MemWload.key

Inherited property, see lisa.wlgen.rta.PropertyBase.key

Key of the instance.

property MemWload.logger

Inherited property, see lisa.utils.Loggable.logger

Convenience short-hand for self.get_logger().

property MemWload.val

Inherited property, see lisa.wlgen.rta.WloadPropertyBase.val

Value “payload” of the property.

Methods

MemWload.__and__()

Combine two instances of the same property together.

This is used to combine properties at the various levels of the RTAPhaseTree tree, on each path from the root to the leaves. It is guaranteed that the instance closer to the root will be self and the one closer to the leaves will be other.

If the property is a constraint, a good implementation should combine two instances by applying the strongest constraint. For example, CPU affinity are combined by taking the intersection of allowed CPUs.

If the property is some sort of “dummy” structure, it can make sense to allow the instance closer to the root of the tree to override the set members in the instance closer to the leaves.

Otherwise, it’s probably best to just bail with ValueError with a message explaining that there is a conflict.

MemWload.to_events(**kwargs)

MemWload.HASH_COERCE(x, coerce)

Inherited method, see lisa.utils.SimpleHash.HASH_COERCE()

Used to coerce the values of self.__dict__ to hashable values.

MemWload.__add__(other)

Inherited method, see lisa.wlgen.rta.WloadPropertyBase.__add__()

Adding two workloads together concatenates them.

MemWload.__await__()

Inherited method, see lisa.wlgen.rta.WloadPropertyBase.__await__()

MemWload.__mul__(n)

Inherited method, see lisa.wlgen.rta.WloadPropertyBase.__mul__()

Replicate the given workload n times.

MemWload.__rmul__(n)

Inherited method, see lisa.wlgen.rta.WloadPropertyBase.__rmul__()

classmethod MemWload.check_kconfig(plat_info, strict=True)

Inherited method, see lisa.wlgen.rta.ConcretePropertyBase.check_kconfig()

Check whether plat_info contains the kernel KCONFIG keys contained in REQUIRED_KCONFIG_KEYS.

classmethod MemWload.find_cls(key)

Inherited method, see lisa.wlgen.rta.PropertyBase.find_cls()

Find which subclass can handle key.

classmethod MemWload.from_key(key, val)

Inherited method, see lisa.wlgen.rta.PropertyBase.from_key()

Alternative constructor that is available with the same signature for all properties.

classmethod MemWload.get_logger(suffix=None)

Inherited method, see lisa.utils.Loggable.get_logger()

Provides a logging.Logger named after cls.

classmethod MemWload.log_locals(var_names=None, level='debug')

Inherited method, see lisa.utils.Loggable.log_locals()

Debugging aid: log the local variables of the calling function.

classmethod MemWload.to_default_json(plat_info, properties)

Inherited method, see lisa.wlgen.rta.ConcretePropertyBase.to_default_json()

Similar to to_json() but returns the default values for the keys set in to_json().

MemWload.to_json(plat_info, **kwargs)

Inherited method, see lisa.wlgen.rta.ConcretePropertyBase.to_json()

Snippet of JSON content for that property as Python objects.
