H A Dnetmem.rst29 1. 驱动必须支持page_pool。
33 3. 驱动必须使用page_pool netmem API处理有效载荷内存。当前netmem API
48 程序必须将 DMA 映射操作委托给 page_pool，由其判断何时适合（或不适合）
51 完成 DMA 同步。此时驱动程序必须将 DMA 同步操作委托给 page_pool，由
63 netmem 或 page_pool 辅助函数（并可根据需要添加更多）。
66 对于某些内存提供者，CPU 的 DMA 同步将由 page_pool 完成；而对于其他提供者
68 间负责。驱动程序必须将整个 DMA 同步操作委托给 page_pool，以确保操作正确执行。
70 7. 避免在 page_pool 之上实现特定于驱动程序内存回收机制。由于 netmem 可能
73 page_pool 引用，但需注意某些 netmem 类型的循环时间可能更长（例如零拷贝场景

H A Dnetmem.rst25 1. The driver must support page_pool.
29 3. The driver must use the page_pool netmem APIs for payload memory. The netmem
46 must delegate the dma mapping to the page_pool, which knows when
49 by the driver. The driver must delegate the dma syncing to the page_pool,
55 The netmem returned by the page_pool may be unreadable, in which case
63 netmem or page_pool helpers that abstract this complexity are provided
68 CPU will be done by the page_pool, for others (particularly dmabuf memory
71 the page_pool which will do it correctly.
73 7. Avoid implementing driver-specific recycling on top of the page_pool. Drivers
75 not be backed by a struct page. However, you may hold onto a page_pool
