For example, * copying to system memory could be done with memcpy(), copying to I/O memory * would be done with memcpy_toio(). * * .. code-block:: c * * void *vaddr = ...; // pointer to system memory * memcpy(vaddr, src, len); * * void *vaddr_iomem = ...; // pointer to I/O memory * memcpy_toio(vaddr_iomem, src, len); * * The user of such pointer may not have information about the mapping of that * region or may want to have a single code path to handle operations on that * buffer, regardless if it's located in system or IO memory. The type * :c:type:`struct iosys_map ` and its helpers abstract that so the * buffer can be passed around to other drivers or have separate duties inside * the same driver for allocation, read and write operations. * * Open-coding access to :c:type:`struct iosys_map ` is considered * bad style. Rather then accessing its fields directly, use one of the provided * helper functions, or implement your own. For example, instances of * :c:type:`struct iosys_map ` can be initialized statically with * IOSYS_MAP_INIT_VADDR(), or at runtime with iosys_map_set_vaddr(). These * helpers will set an address in system memory. * * .. code-block:: c * * struct iosys_map map = IOSYS_MAP_INIT_VADDR(0xdeadbeaf); * * iosys_map_set_vaddr(&map, 0xdeadbeaf); * * To set an address in I/O memory, use IOSYS_MAP_INIT_VADDR_IOMEM() or * iosys_map_set_vaddr_iomem(). * * .. code-block:: c * * struct iosys_map map = IOSYS_MAP_INIT_VADDR_IOMEM(0xdeadbeaf); * * iosys_map_set_vaddr_iomem(&map, 0xdeadbeaf); * * Instances of struct iosys_map do not have to be cleaned up, but * can be cleared to NULL with iosys_map_clear(). Cleared mappings * always refer to system mem
