许多函数在本章中已经被介绍过; 这是它们全部的一个快速总结.
- #include <linux/kobject.h>
包含文件, 包含 kobject 的定义, 相关结构, 和函数.
- void kobject_init(struct kobject *kobj);
-
- int kobject_set_name(struct kobject *kobj, const char *format, ...);
用作 kobject 初始化的函数
- struct kobject *kobject_get(struct kobject *kobj);
-
- void kobject_put(struct kobject *kobj);
为 kobjects 管理引用计数的函数.
- struct kobj_type;
-
- struct kobj_type *get_ktype(struct kobject *kobj);
表示一个kobjct 被嵌入的结构类型. 使用 get_ktype 来获得关联到一个给定 kobject 的 kobj_type.
- int kobject_add(struct kobject *kobj);
-
- extern int kobject_register(struct kobject *kobj);
-
- void kobject_del(struct kobject *kobj);
-
- void kobject_unregister(struct kobject *kobj);
kobject_add 添加一个 kobject 到系统, 处理 kset 成员关系, sysfs 表示, 以及热插拔事件产生. kobject_register 是一个方便函数, 它结合 kobject_init 和 kobject_add. 使用 kobject_del 来去除一个 kobject 或者 kobject_unregister, 它结合了 kobject_del 和 kobject_put.
- void kset_init(struct kset *kset);
-
- int kset_add(struct kset *kset);
-
- int kset_register(struct kset *kset);
-
- void kset_unregister(struct kset *kset);
为 ksets 初始化和注册的函数.
- decl_subsys(name, type, hotplug_ops);
易于声明子系统的一个宏.
- void subsystem_init(struct subsystem *subsys);
-
- int subsystem_register(struct subsystem *subsys);
-
- void subsystem_unregister(struct subsystem *subsys);
-
- struct subsystem *subsys_get(struct subsystem *subsys);
-
- void subsys_put(struct subsystem *subsys);
对子系统的操作.
- #include <linux/sysfs.h>
包含 sysfs 声明的包含文件.
- int sysfs_create_file(struct kobject *kobj, struct attribute *attr);
-
- int sysfs_remove_file(struct kobject *kobj, struct attribute *attr);
-
- int sysfs_create_bin_file(struct kobject *kobj, struct bin_attribute *attr);
-
- int sysfs_remove_bin_file(struct kobject *kobj, struct bin_attribute *attr);
-
- int sysfs_create_link(struct kobject *kobj, struct kobject *target, char
*name);
-
- void sysfs_remove_link(struct kobject *kobj, char *name);
创建和去除和一个 kobject 关联的属性文件的函数.
- int bus_register(struct bus_type *bus);
-
- void bus_unregister(struct bus_type *bus);
在设备模型中进行注册和注销总线的函数.
- int bus_for_each_dev(struct bus_type *bus, struct device *start, void *data, int (*fn)(struct device *, void *));
-
- int bus_for_each_drv(struct bus_type *bus, struct device_driver *start, void *data, int (*fn)(struct device_driver *, void *));
-
列举每个设备和驱动的函数, 特别地, 绑定到给定总线的设备.
- BUS_ATTR(name, mode, show, store);
-
- int bus_create_file(struct bus_type *bus, struct bus_attribute *attr);
-
- void bus_remove_file(struct bus_type *bus, struct bus_attribute *attr);
BUS_ATTR 宏可能用来声明一个 bus_attribute 结构, 它可能接着被添加和去除, 使用上面 2 个函数.
- int device_register(struct device *dev);
-
- void device_unregister(struct device *dev);
处理设备注册的函数.
- DEVICE_ATTR(name, mode, show, store);
-
- int device_create_file(struct device *device, struct device_attribute *entry);
-
- void device_remove_file(struct device *dev, struct device_attribute *attr);
处理设备属性的宏和函数.
- int driver_register(struct device_driver *drv);
-
- void driver_unregister(struct device_driver *drv);
注册和注销一个设备驱动的函数.
- DRIVER_ATTR(name, mode, show, store);
-
- int driver_create_file(struct device_driver *drv, struct driver_attribute *attr);
-
- void driver_remove_file(struct device_driver *drv, struct driver_attribute *attr);
关联驱动属性的宏和函数.
- struct class_simple *class_simple_create(struct module *owner, char *name);
-
- void class_simple_destroy(struct class_simple *cs);
-
- struct class_device *class_simple_device_add(struct class_simple *cs, dev_t devnum, struct device *device, const char *fmt, ...);
-
- void class_simple_device_remove(dev_t dev);
-
- int class_simple_set_hotplug(struct class_simple *cs, int (*hotplug)(struct
class_device *dev, char **envp, int num_envp, char *buffer, int
buffer_size));
实现 class_simple 接口的函数; 它们管理包含一个 dev 属性和很少其他属性的简单的类入口
