<!--
|

Enables support for requesting [admin access](/docs/concepts/scheduling-eviction/dynamic-resource-allocation/#admin-access)
|
||||
in a ResourceClaim. A ResourceClaim
|
||||
with admin access grants access to devices which are in use and may enable
|
||||
additional access permissions when making the device available in a container.
|
||||
|
||||
This feature gate has no effect unless you also enable the `DynamicResourceAllocation` feature gate.
|
||||
-->
|
||||
启用在 ResourceClaim
|
||||
中对请求[管理员访问权限](/zh-cn/docs/concepts/scheduling-eviction/dynamic-resource-allocation/#admin-access)的支持。
|
||||
具有管理员访问权限的 ResourceClaim 允许访问正在使用的设备,并且可以在允许容器访问设备时启用额外的访问权限。
|
||||
|
||||
想要此特性门控生效,你还需启用 `DynamicResourceAllocation` 特性门控。

<!--
|
||||
When `PreferAlignCpusByUncoreCache` is enabled while the CPU Manager Policy is set to `static`,
|
||||
containers within a `Guaranteed` pod will individually be aligned to an uncore cache group at
|
||||
a best-effort policy. This feature can optimize performance for certain cache-sensitive workloads
|
||||
by minimizing the cpu allocation across uncore caches.
|
||||
-->
|
||||
当在 CPU 管理器的策略设为 `static` 时启用 `PreferAlignCpusByUncoreCache`,
|
||||
`Guaranteed` Pod 中的容器将基于尽力而为策略逐个与某个非核心缓存组对齐。
|
||||
此特性可以通过最小化跨非核心缓存的 CPU 分配量来优化某些对缓存敏感的负载的性能。
