================
链路电源管理策略
================
该参数允许用户设置链路（接口）的电源管理模式。
共计三类可选项：
===================== =====================================================
选项 作用
===================== =====================================================
min_power 指示控制器在可能的情况下尽量使链路处于最低功耗。
这可能会牺牲一定的性能，因为从低功耗状态恢复时会增加延迟。
max_performance 通常，这意味着不进行电源管理。指示
控制器优先考虑性能而非电源管理。
medium_power 指示控制器在可能的情况下进入较低功耗状态，
而非最低功耗状态，从而改善min_power模式下的延迟。

Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
