Specification

Property Type Description

apiVersion

string

APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources

kind

string

Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds

metadata

ObjectMeta_v2

Standard object’s metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata

spec

object

PerformanceProfileSpec defines the desired state of PerformanceProfile.

status

object

PerformanceProfileStatus defines the observed state of PerformanceProfile.

.spec

Description

PerformanceProfileSpec defines the desired state of PerformanceProfile.

Type

object

Required
  • cpu

  • nodeSelector

Property Type Description

additionalKernelArgs

array (string)

Addional kernel arguments.

cpu

object

CPU defines a set of CPU related parameters.

globallyDisableIrqLoadBalancing

boolean

GloballyDisableIrqLoadBalancing toggles whether IRQ load balancing will be disabled for the Isolated CPU set. When the option is set to "true" it disables IRQs load balancing for the Isolated CPU set. Setting the option to "false" allows the IRQs to be balanced across all CPUs, however the IRQs load balancing can be disabled per pod CPUs when using irq-load-balancing.crio.io/cpu-quota.crio.io annotations. Defaults to "false"

hugepages

object

HugePages defines a set of huge pages related parameters. It is possible to set huge pages with multiple size values at the same time. For example, hugepages can be set with 1G and 2M, both values will be set on the node by the performance addon controller. It is important to notice that setting hugepages default size to 1G will remove all 2M related folders from the node and it will be impossible to configure 2M hugepages under the node.

machineConfigLabel

object (string)

MachineConfigLabel defines the label to add to the MachineConfigs the operator creates. It has to be used in the MachineConfigSelector of the MachineConfigPool which targets this performance profile. Defaults to "machineconfiguration.openshift.io/role=<same role as in NodeSelector label key>"

machineConfigPoolSelector

object (string)

MachineConfigPoolSelector defines the MachineConfigPool label to use in the MachineConfigPoolSelector of resources like KubeletConfigs created by the operator. Defaults to "machineconfiguration.openshift.io/role=<same role as in NodeSelector label key>"

net

object

Net defines a set of network related features

nodeSelector

object (string)

NodeSelector defines the Node label to use in the NodeSelectors of resources like Tuned created by the operator. It most likely should, but does not have to match the node label in the NodeSelector of the MachineConfigPool which targets this performance profile. In the case when machineConfigLabels or machineConfigPoolSelector are not set, we are expecting a certain NodeSelector format <domain>/<role>: "" in order to be able to calculate the default values for the former mentioned fields.

numa

object

NUMA defines options related to topology aware affinities

realTimeKernel

object

RealTimeKernel defines a set of real time kernel related parameters. RT kernel won’t be installed when not set.

workloadHints

object

WorkloadHints defines hints for different types of workloads. It will allow defining exact set of tuned and kernel arguments that should be applied on top of the node.

.spec.cpu

Description

CPU defines a set of CPU related parameters.

Type

object

Required
  • isolated

  • reserved

Property Type Description

balanceIsolated

boolean

BalanceIsolated toggles whether or not the Isolated CPU set is eligible for load balancing work loads. When this option is set to "false", the Isolated CPU set will be static, meaning workloads have to explicitly assign each thread to a specific cpu in order to work across multiple CPUs. Setting this to "true" allows workloads to be balanced across CPUs. Setting this to "false" offers the most predictable performance for guaranteed workloads, but it offloads the complexity of cpu load balancing to the application. Defaults to "true"

isolated

string

Isolated defines a set of CPUs that will be used to give to application threads the most execution time possible, which means removing as many extraneous tasks off a CPU as possible. It is important to notice the CPU manager can choose any CPU to run the workload except the reserved CPUs. In order to guarantee that your workload will run on the isolated CPU: 1. The union of reserved CPUs and isolated CPUs should include all online CPUs 2. The isolated CPUs field should be the complementary to reserved CPUs field

offlined

string

Offline defines a set of CPUs that will be unused and set offline

reserved

string

Reserved defines a set of CPUs that will not be used for any container workloads initiated by kubelet.

.spec.hugepages

Description

HugePages defines a set of huge pages related parameters. It is possible to set huge pages with multiple size values at the same time. For example, hugepages can be set with 1G and 2M, both values will be set on the node by the performance addon controller. It is important to notice that setting hugepages default size to 1G will remove all 2M related folders from the node and it will be impossible to configure 2M hugepages under the node.

Type

object

string

DefaultHugePagesSize defines huge pages default size under kernel boot parameters.

pages

array

Pages defines huge pages that we want to allocate at boot time.

object

Type

array

.spec.hugepages.pages[]

Description

Type

object

Property Type Description

count

integer

Count defines amount of huge pages, maps to the 'hugepages' kernel boot parameter.
