Modules
	User-space driver core
	This profile includes all mini-drivers sitting on top of the User-space Device Driver framework (UDD).
	CAN Devices
	This is the common interface a RTDM-compliant CAN device has to provide.
	Serial Devices
	This is the common interface a RTDM-compliant serial device has to provide.
	Testing Devices
	This group of devices is intended to provide in-kernel testing results.
	Real-time IPC
	Profile Revision: 1

Data Structures
struct	rtdm_device_info
	Device information. More...

Typedefs
typedef struct rtdm_device_info	rtdm_device_info_t
	Device information.

Common IOCTLs
The following IOCTLs are common to all device rtdm_profiles.
#define	RTIOC_DEVICE_INFO    _IOR(RTIOC_TYPE_COMMON, 0x00, struct rtdm_device_info)
	Retrieve information about a device or socket.
#define	RTIOC_PURGE   _IOW(RTIOC_TYPE_COMMON, 0x10, int)
	Purge internal device or socket buffers.

Detailed Description

Pre-defined classes of real-time devices.

Device profiles define which operation handlers a driver of a certain class of devices has to implement, which name or protocol it has to register, which IOCTLs it has to provide, and further details. Sub-classes can be defined in order to extend a device profile with more hardware-specific functions.
