Linux Kernel设备驱动模型之struct kset

    xiaoxiao2021-03-25  125

    在设备驱动模型中,我们用kobject表示设备的基类,而一些相同的设备构成集合,即kset:  

    /**  * struct kset - a set of kobjects of a specific type, belonging to a specific subsystem.  *  * A kset defines a group of kobjects.  They can be individually  * different "types" but overall these kobjects all want to be grouped  * together and operated on in the same manner.  ksets are used to  * define the attribute callbacks and other common events that happen to  * a kobject.  *  * @list: the list of all kobjects for this kset  * @list_lock: a lock for iterating over the kobjects  * @kobj: the embedded kobject for this kset (recursion, isn't it fun...)  * @uevent_ops: the set of uevent operations for this kset.  These are  * called whenever a kobject has something happen to it so that the kset  * can add new environment variables, or filter out the uevents if so  * desired.  */ struct kset {  struct list_head list;  spinlock_t list_lock;  struct kobject kobj;  const struct kset_uevent_ops *uevent_ops; };
