<1> The policies are applied to all clusters with this label.
|
|
<2> The `MCP` field must be set to `worker`.
|
|
<3> This generic `MachineConfig` CR is used to configure workload partitioning on the worker node.
|
|
<4> The `cpu.isolated` and `cpu.reserved` fields must be configured for each particular hardware platform.
|
|
<5> The `cmdline_crash` CPU set must match the `cpu.isolated` set in the `PerformanceProfile` section.
