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

- Type
`object`- Required
-
| Property |
Type |
Description |
additionalKernelArgs |
array (string) |
Additional 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" |
hardwareTuning |
object |
HardwareTuning defines a set of CPU frequencies for isolated and reserved cpus. |
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 Profile 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. |
kernelPageSize |
string |
KernelPageSize defines the kernel page size. 4k is the default, 64k is only supported on aarch64 |
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 |

-
| 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. |
shared |
string |
Shared defines a set of CPUs that will be shared among guaranteed workloads that needs additional cpus which are not exclusive, alongside the isolated, exclusive resources that are being used already by those workloads. |
