53As explained in Documentation/kobject.txt, device attributes must be be
54created before the KOBJ_ADD uevent is generated. The only way to realize
55that is by defining an attribute group.
56
54Attributes are declared using a macro called DEVICE_ATTR: 57Attributes are declared using a macro called DEVICE_ATTR:
55 58
56#define DEVICE_ATTR(name,mode,show,store) 59#define DEVICE_ATTR(name,mode,show,store)
57 60
58Example: 61Example:

60DEVICE_ATTR(power,0644,show_power,store_power); 63static DEVICE_ATTR(type, 0444, show_type, NULL);
64static DEVICE_ATTR(power, 0644, show_power, store_power);
61 65
62This declares a structure of type struct device_attribute named 66This declares two structures of type struct device_attribute with respective
63'dev_attr_power'. This can then be added and removed to the device's 67names 'dev_attr_type' and 'dev_attr_power'. These two attributes can be
64directory using: 68organized as follows into a group:
65 69
66int device_create_file(struct device *device, struct device_attribute * entry); 70static struct attribute *dev_attrs[] = {
67void device_remove_file(struct device * dev, struct device_attribute * attr); 71 &dev_attr_type.attr,
72 &dev_attr_power.attr,
73 NULL,
74};
68 75
69Example: 76static struct attribute_group dev_attr_group = {
77 .attrs = dev_attrs,
78};
79
80static const struct attribute_group *dev_attr_groups[] = {
81 &dev_attr_group,
82 NULL,
83};
84
85This array of groups can then be associated with a device by setting the
86group pointer in struct device before device_register() is invoked:
70 87
71device_create_file(dev,&dev_attr_power); 88 dev->groups = dev_attr_groups;
72device_remove_file(dev,&dev_attr_power); 89 device_register(dev);
73 90
74The file name will be 'power' with a mode of 0644 (-rw-r--r--). 91The device_register() function will use the 'groups' pointer to create the
92device attributes and the device_unregister() function will use this pointer
93to remove the device attributes.

88probably use class_create() and class->dev_attrs to set up a list of
89desired attributes in the modules_init function, and then in the .probe()
90hook, and then use device_create() to create a new device as a child
91of the probed device. The new device will generate a new uevent and
92properly advertise the new attributes to userspace.
93
94For example, if a driver wanted to add the following attributes:
95struct device_attribute mydriver_attribs[] = {
96 __ATTR(port_count, 0444, port_count_show),
97 __ATTR(serial_number, 0444, serial_number_show),

101Then in the module init function is would do:
102 mydriver_class = class_create(THIS_MODULE, "my_attrs");
103 mydriver_class.dev_attr = mydriver_attribs;
104
105And assuming 'dev' is the struct device passed into the probe hook, the driver
106probe function would do something like:
107 device_create(&mydriver_class, dev, chrdev, &private_data, "my_name");
