+ * objpool is a scalable implementation of high performance queue for

+ *
+ * With leveraging percpu ring-array to mitigate hot spots of memory

+ * 1) Memory allocation or reclamation are prohibited or too expensive
+ * 2) Consumers are of different priorities, such as irqs and threads
+ *
+ * Limitations:
+ * 1) Maximum objects (capacity) is fixed after objpool creation
+ * 2) All pre-allocated objects are managed in percpu ring array,
+ * which consumes more memory than linked lists

+ * @mask: bits mask for modulo capacity to compute array indexes
+ * @entries: object entries on this slot
+ *
+ * Represents a cpu-local array-based ring buffer, its size is specialized
+ * during initialization of object pool. The percpu objpool node is to be
+ * allocated from local memory for NUMA system, and to be kept compact in
+ * continuous memory: CPU assigned number of objects are stored just after
+ * the body of objpool_node.
+ *
+ * Real size of the ring array is far too smaller than the value range of
+ * head and tail, typed as uint32_t: [0, 2^32), so only lower bits (mask)
+ * of head and tail are used as the actual position in the ring array. In

+ *
+ * The evetnfs files are dynamically created. The struct eventfs_entry array
+ * is passed to eventfs_create_dir() or eventfs_create_events_dir() that will
+ * be used to create the files within those directories. When a lookup
+ * or access to a file within the directory is made, the struct eventfs_entry
+ * array is used to find a callback() with the matching name that is being
+ * referenced (for lookups, the entire array is iterated and each callback
+ * will be called).
+ *
+ * The callback will be called with @name for the name of the file to create.
+ * The callback can return less than 1 to indicate that no file should be
+ * created.
+ *
+ * If a file is to be created, then @mode should be populated with the file
+ * mode (permissions) for which the file is created for. This would be
+ * used to set the created inode i_mode field.
+ *
+ * The @data should be set to the data passed to the other file operations
+ * (read, write, etc). Note, @data will also point to the data passed in
+ * to eventfs_create_dir() or eventfs_create_events_dir(), but the callback
+ * can replace the data if it chooses to. Otherwise, the original data
+ * will be used for the file operation functions.
+ *
+ * The @fops should be set to the file operations that will be used to create
+ * the inode.
+ *
+ * NB. This callback is called while holding internal locks of the eventfs
+ * system. The callback must not call any code that might also call into

/**
* DOC: page_pool allocator
*
- * The page_pool allocator is optimized for the XDP mode that
- * uses one frame per-page, but it can fallback on the
- * regular page allocator APIs.
- *
- * Basic use involves replacing alloc_pages() calls with the
- * page_pool_alloc_pages() call. Drivers should use
- * page_pool_dev_alloc_pages() replacing dev_alloc_pages().
- *
- * The API keeps track of in-flight pages, in order to let API users know
- * when it is safe to free a page_pool object. Thus, API users
- * must call page_pool_put_page() to free the page, or attach
- * the page to a page_pool-aware object like skbs marked with
+ * The page_pool allocator is optimized for recycling page or page fragment used
+ * by skb packet and xdp frame.
+ *
+ * Basic use involves replacing and alloc_pages() calls with page_pool_alloc(),
+ * which allocate memory with or without page splitting depending on the
+ * requested memory size.
+ *
+ * If the driver knows that it always requires full pages or its allocations are
+ * always smaller than half a page, it can use one of the more specific API
+ * calls:
+ *
+ * 1. page_pool_alloc_pages(): allocate memory without page splitting when
+ * driver knows that the memory it need is always bigger than half of the page
+ * allocated from page pool. There is no cache line dirtying for 'struct page'
+ * when a page is recycled back to the page pool.
+ *
+ * 2. page_pool_alloc_frag(): allocate memory with page splitting when driver
+ * knows that the memory it need is always smaller than or equal to half of the
+ * page allocated from page pool. Page splitting enables memory saving and thus
+ * avoids TLB/cache miss for data access, but there also is some cost to
+ * implement page splitting, mainly some cache line dirtying/bouncing for
+ * 'struct page' and atomic operation for page->pp_frag_count.
+ *
+ * The API keeps track of in-flight pages, in order to let API users know when
+ * it is safe to free a page_pool object, the API users must call
+ * page_pool_put_page() or page_pool_free_va() to free the page_pool object, or
+ * attach the page_pool object to a page_pool-aware object like skbs marked with
* skb_mark_for_recycle().
*
- * API users must call page_pool_put_page() once on a page, as it
- * will either recycle the page, or in case of refcnt > 1, it will
- * release the DMA mapping and in-flight state accounting.
+ * page_pool_put_page() may be called multi times on the same page if a page is
+ * split into multi fragments. For the last fragment, it will either recycle the
+ * page, or in case of page->_refcount > 1, it will release the DMA mapping and
+ * in-flight state accounting.
+ *
+ * dma_sync_single_range_for_device() is only called for the last fragment when
+ * page_pool is created with PP_FLAG_DMA_SYNC_DEV flag, so it depends on the
+ * last freed fragment to do the sync_for_device operation for all fragments in
+ * the same page when a page is split, the API user must setup pool->p.max_len
+ * and pool->p.offset correctly and ensure that page_pool_put_page() is called
+ * with dma_sync_size being -1 for fragment API.
