Summary

Allow eviction plugins to report pressure for individual CNR topology zones and configure reclaimed-cgroup memory suppression eviction through AdminQoSConfiguration.

• Add Condition.zone_taints, TopologyZoneRef, and TopologyZoneTaint to carry ordered topology paths, condition names, QoS levels, effects, and pressure states.
• Add optional memorySuppressionEvictionConfig fields for enablement, high/max event thresholds, observation window, and required pressure fraction.
• Preserve existing protobuf field numbers and distinguish omitted configuration fields from explicit false and 0.
• Regenerate protobuf bindings, deep-copy code, and the AQC CRD.

High/max thresholds are expressed as events per 10 seconds and normalized by the actual sampling interval. Zero disables the corresponding signal. The required pressure fraction is in (0, 1]; omitted fields retain the consumer's startup configuration.

Validation

Passed locally:

• go test -gcflags=all=-l -race -count=1 ./pkg/apis/config/v1alpha1 ./pkg/protocol/evictionplugin/v1alpha1
• go vet ./pkg/apis/config/v1alpha1

Tests cover protocol wire round trips, JSON round trips, omitted fields, explicit false/zero values, and deep-copy isolation.

English

• Added Condition.zone_taints to the eviction-plugin protobuf API. TopologyZoneRef describes each item in a topology path, and TopologyZoneTaint carries the condition, QoS level, effect, and pressure state for that path. Existing Condition field numbers remain unchanged; the new field uses number 5.
• Added optional BEMemorySuppressionEvictionConfig to EvictionConfig. It exposes enablement, high and max event thresholds, an observation window, and a required pressure fraction. Pointer fields preserve the distinction between omitted values and explicit false or 0. Thresholds are specified per ten seconds and normalized for the sample interval; zero disables the corresponding signal.
• Regenerated the protobuf bindings, deepcopy code, and AQC CRD. The changes add API surface; they are not documentation-only or generated-only.
• Downstream eviction-plugin consumers can use zone-level taints. Consumers that support reclaimed-cgroup memory suppression can read the new AQC fields and should preserve omitted values as unset. The author reports that package tests and go vet passed locally; no independent test run is provided here.

简体中文

• 在 eviction-plugin protobuf API 中新增 Condition.zone_taints。TopologyZoneRef 描述拓扑路径中的各项，TopologyZoneTaint 为该路径携带 condition、QoS level、effect 和 pressure state。现有 Condition 字段编号保持不变；新字段使用编号 5。
• 在 EvictionConfig 中新增可选的 BEMemorySuppressionEvictionConfig。该配置提供 enablement、high 和 max 事件阈值、观察窗口以及所需的 pressure fraction。指针字段可区分未提供的值与显式设置的 false 或 0。阈值按每十秒定义，并根据采样间隔归一化；值为零时禁用对应信号。
• 已重新生成 protobuf bindings、deepcopy 代码和 AQC CRD。这些变更扩展了 API，并非仅修改文档或仅包含生成文件。
• 下游 eviction-plugin consumer 可使用 zone-level taints。支持 reclaimed-cgroup memory suppression 的 consumer 可读取新增的 AQC 字段，并应将未提供的字段保留为 unset。作者报告本地 package tests 和 go vet 已通过；此处没有独立测试结果。

Expose the contracted JSON field name.

When a manifest or client uses spec.evictionConfig.memorySuppressionEvictionConfig, the field does not bind because EvictionConfig declares the JSON tag as beMemorySuppressionEvictionConfig. The generated CRD exposes only the be... property, so the intended key cannot configure this feature.

简体中文：当 manifest 或客户端使用 spec.evictionConfig.memorySuppressionEvictionConfig 时，该字段不会绑定，因为 EvictionConfig 声明的 JSON tag 是 beMemorySuppressionEvictionConfig。生成的 CRD 只暴露了 be... 属性，因此预期的 key 无法配置此功能。
