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

config UIO_CIF
tristate "generic Hilscher CIF Card driver"
depends on PCI
help
Driver for Hilscher CIF DeviceNet and Profibus cards. This
driver requires a userspace component called cif that handles
all of the heavy lifting and can be found at:
<http://www.osadl.org/projects/downloads/UIO/user/>
To compile this driver as a module, choose M here: the module
will be called uio_cif.
config UIO_PDRV_GENIRQ
tristate "Userspace I/O platform driver with generic IRQ handling"
help
Platform driver for Userspace I/O devices, including generic
interrupt handling code. Shared interrupts are not supported.
This kernel driver requires that the matching userspace driver
handles interrupts in a special way. Userspace is responsible
for acknowledging the hardware device if needed, and re-enabling
interrupts in the interrupt controller using the write() syscall.
If you don't know what to do here, say N.
config UIO_DMEM_GENIRQ
tristate "Userspace platform driver with generic irq and dynamic memory"
depends on HAS_DMA
help
Platform driver for Userspace I/O devices, including generic
interrupt handling code. Shared interrupts are not supported.
Memory regions can be specified with the same platform device
resources as the UIO_PDRV drivers, but dynamic regions can also
be specified.
The number and size of these regions is static,
but the memory allocation is not performed until
the associated device file is opened. The
memory is freed once the uio device is closed.
If you don't know what to do here, say N.
config UIO_AEC
tristate "AEC video timestamp device"
depends on PCI
help
UIO driver for the Adrienne Electronics Corporation PCI time
code device.
This device differs from other UIO devices since it uses I/O
ports instead of memory mapped I/O. In order to make it
possible for UIO to work with this device a utility, uioport,
can be used to read and write the ports:
git clone git://ifup.org/philips/uioport.git
If you compile this as a module, it will be called uio_aec.
config UIO_SERCOS3
tristate "Automata Sercos III PCI card driver"
depends on PCI
help
Userspace I/O interface for the Sercos III PCI card from
Automata GmbH. The userspace part of this driver will be
available for download from the Automata GmbH web site.
Automata GmbH: http://www.automataweb.com
Sercos III interface: http://www.sercos.com
If you compile this as a module, it will be called uio_sercos3.
config UIO_PCI_GENERIC
tristate "Generic driver for PCI 2.3 and PCI Express cards"
depends on PCI
help
Generic driver that you can bind, dynamically, to any
PCI 2.3 compliant and PCI Express card. It is useful,
primarily, for virtualization scenarios.
If you compile this as a module, it will be called uio_pci_generic.
config UIO_NETX
tristate "Hilscher NetX Card driver"
depends on PCI
help
Driver for Hilscher NetX based fieldbus cards (cifX, comX).
This driver requires a userspace component that comes with the card
or is available from Hilscher (http://www.hilscher.com).
To compile this driver as a module, choose M here; the module
will be called uio_netx.
config UIO_FSL_ELBC_GPCM
tristate "eLBC/GPCM driver"
depends on FSL_LBC
help
Generic driver for accessing a peripheral connected to an eLBC port
that is running in GPCM mode. GPCM is an interface for simple lower
performance memories and memory-mapped devices. For devices using
FCM or UPM eLBC modes, other device-specific drivers are available.
config UIO_FSL_ELBC_GPCM_NETX5152
bool "eLBC/GPCM netX 51/52 support"
depends on UIO_FSL_ELBC_GPCM
help
This will add support for netX 51/52 devices connected via eLBC/GPCM.
In particular, it implements interrupt handling. This can be used
together with the userspace netX stack from Hilscher.

config UIO_MF624
tristate "Humusoft MF624 DAQ PCI card driver"
depends on PCI
help
Userspace I/O interface for the Humusoft MF624 PCI card.
A sample userspace application using this driver is available
(among other MF624 related information and software components)
for download in a git repository:
git clone git://rtime.felk.cvut.cz/mf6xx.git
If you compile this as a module, it will be called uio_mf624.
config UIO_HV_GENERIC
tristate "Generic driver for Hyper-V VMBus"
depends on HYPERV
help
Generic driver that you can bind, dynamically, to any
Hyper-V VMBus device. It is useful to provide direct access
to network and storage devices from userspace.
If you compile this as a module, it will be called uio_hv_generic.
config UIO_DFL
tristate "Generic driver for DFL (Device Feature List) bus"
depends on FPGA_DFL
help
Generic DFL (Device Feature List) driver for Userspace I/O devices.
It is useful to provide direct access to DFL devices from userspace.
A sample userspace application using this driver is available for
download in a git repository:
git clone https://github.com/OPAE/opae-sdk.git
