I am seeing probe function pointer and know the procedure to register of it for a specific device driver. However, I wonder when it is actually called?
For example, for platform drivers, there is a structure like this:
struct platform_driver {
int (*probe)(struct platform_device *);
int (*remove)(struct platform_device *);
void (*shutdown)(struct platform_device *);
int (*suspend)(struct platform_device *, pm_message_t state);
int (*suspend_late)(struct platform_device *, pm_message_t state);
int (*resume_early)(struct platform_device *);
int (*resume)(struct platform_device *);
struct device_driver driver;
};
Then, it is registered by
int platform_driver_register(struct platform_driver *drv);But, I wonder when actually, those functions (especially, probe) are called. Could you guide me about it, please?
Thanks,
-J.
