📝 Walkthrough

Walkthrough

The configuration API adds optional memory fragmentation, THP, and host-watermark settings. Generated deepcopy methods copy these settings through nested configuration objects.

配置 API 新增可选的内存碎片整理、THP 和主机水位设置。生成的深拷贝方法会复制这些嵌套配置对象。

Changes

Memory configuration API / 内存配置 API

Layer / File(s)	Summary
Memory configuration schema pkg/apis/config/v1alpha1/adminqos.go	QRMPluginConfig now includes MemoryPluginConfig. The new types define fragmentation, THP, VM watermark, and reserved kswapd memory settings. QRMPluginConfig 现在包含 MemoryPluginConfig。新增类型定义内存碎片整理、THP、VM 水位和预留 kswapd 内存设置。
Memory configuration deepcopy pkg/apis/config/v1alpha1/zz_generated.deepcopy.go	Generated methods copy all new pointer fields and nested configurations. QRMPluginConfig.DeepCopyInto now copies MemoryPluginConfig. 生成的方法复制所有新增指针字段和嵌套配置。QRMPluginConfig.DeepCopyInto 现在会复制 MemoryPluginConfig。

tags in FragMemConfig and HostWatermarkConfig as deprecated compatibility
fields, while retaining the renamed fields only if needed for the new API shape.
Ensure old manifest keys continue to deserialize and remain represented in
generated CRDs; do not replace the prior fields or wire keys without adding an
explicit API-version conversion and migration.
