Expose THPConfigPolicy in FragMemConfig so CRD users can choose between static THP enforcement and the existing dynamic fragmentation-based tuning behavior.

Special notes for your reviewer:

English

  • API surface: Adds optional FragMemConfig.THPConfigPolicy *string with JSON key thpConfigPolicy. The CRD accepts "static" and "dynamic" and defaults to "dynamic".
  • Behavior: "static" enforces THPDefaultConfig. "dynamic" preserves fragmentation-based THP tuning.
  • Compatibility: Existing CRDs remain compatible. Unset fields retain dynamic behavior.
  • Code generation: Updates FragMemConfig.DeepCopyInto to deep-copy THPConfigPolicy. Regenerate API-derived files after future API changes.
  • Downstream updates: CRD users can set thpConfigPolicy. Consumers that expose or validate FragMemConfig may need updates.
  • Tests: Add or update API and deepcopy tests if coverage exists.

简体中文

  • API surface:FragMemConfig 增加可选字段 THPConfigPolicy *string,JSON key 为 thpConfigPolicy。CRD 接受 "static""dynamic",默认值为 "dynamic"
  • 行为: "static" 强制使用 THPDefaultConfig"dynamic" 保留基于内存碎片的 THP 调优行为。
  • 兼容性: 现有 CRD 保持兼容。未设置该字段时继续使用动态行为。
  • 代码生成: 更新 FragMemConfig.DeepCopyInto,以深拷贝 THPConfigPolicy。后续 API 变更后需要重新生成 API 派生文件。
  • 下游更新: CRD 用户可以设置 thpConfigPolicy。需要暴露或校验 FragMemConfig 的消费者可能需要更新。
  • 测试: 如果仓库已有相关覆盖,请增加或更新 API 和 deepcopy 测试。

📝 Walkthrough

Walkthrough

FragMemConfig now supports optional static or dynamic THP configuration through THPConfigPolicy. Deep-copy logic preserves the pointer value without sharing its allocation.

FragMemConfig 现在通过 THPConfigPolicy 支持可选的 static 或 dynamic THP 配置。深拷贝逻辑会保留指针值,并避免共享内存分配。

Changes

THP configuration policy / THP 配置策略

Layer / File(s) Summary
THP policy contract and copy support / THP 策略契约与拷贝支持
pkg/apis/config/v1alpha1/adminqos.go, pkg/apis/config/v1alpha1/zz_generated.deepcopy.go
FragMemConfig adds optional THPConfigPolicy, with static and dynamic values and a default of dynamic. DeepCopyInto copies the pointed-to string into a new allocation.

FragMemConfig 新增可选的 THPConfigPolicy,支持 staticdynamic 值,默认值为 dynamicDeepCopyInto 将字符串值复制到新的内存分配中。

so it accepts only “static” or “dynamic” and defaults to “dynamic” when omitted,
preserving the existing JSON field and policy semantics.
