3	tristate "Userspace I/O drivers"
4	depends on MMU
5	help
6	  Enable this to allow the userspace driver core code to be
7	  built.  This code allows userspace programs easy access to
8	  kernel interrupts and memory locations, allowing some drivers
9	  to be written in userspace.  Note that a small kernel driver
10	  is also required for interrupt handling to work properly.

18	depends on PCI
19	help
20	  Driver for Hilscher CIF DeviceNet and Profibus cards.  This
21  	  driver requires a userspace component called cif that handles
22	  all of the heavy lifting and can be found at:
23	        <http://www.osadl.org/projects/downloads/UIO/user/>
24
25	  To compile this driver as a module, choose M here: the module
26	  will be called uio_cif.

28config UIO_PDRV_GENIRQ
29	tristate "Userspace I/O platform driver with generic IRQ handling"
30	help
31	  Platform driver for Userspace I/O devices, including generic
32	  interrupt handling code. Shared interrupts are not supported.
33
34	  This kernel driver requires that the matching userspace driver
35	  handles interrupts in a special way. Userspace is responsible
36	  for acknowledging the hardware device if needed, and re-enabling
37	  interrupts in the interrupt controller using the write() syscall.
38
39	  If you don't know what to do here, say N.

44	help
45	  Platform driver for Userspace I/O devices, including generic
46	  interrupt handling code. Shared interrupts are not supported.
47
48	  Memory regions can be specified with the same platform device
49	  resources as the UIO_PDRV drivers, but dynamic regions can also
50	  be specified.
51	  The number and size of these regions is static,
52	  but the memory allocation is not performed until
53	  the associated device file is opened. The
54	  memory is freed once the uio device is closed.

61	help
62
63	  UIO driver for the Adrienne Electronics Corporation PCI time
64	  code device.
65
66	  This device differs from other UIO devices since it uses I/O
67	  ports instead of memory mapped I/O. In order to make it
68	  possible for UIO to work with this device a utility, uioport,
69	  can be used to read and write the ports:
70
71	    git clone git://ifup.org/philips/uioport.git
72
73	  If you compile this as a module, it will be called uio_aec.

112	  Generic driver for accessing a peripheral connected to an eLBC port
113	  that is running in GPCM mode. GPCM is an interface for simple lower
114	  performance memories and memory-mapped devices. For devices using
115	  FCM or UPM eLBC modes, other device-specific drivers are available.
