menuconfig UIO tristate "Userspace I/O drivers" depends on !S390 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. If you don't know what to do here, say N. if UIO 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 that handles all of the heavy lifting and can be found at: http://www.osadl.org/projects/downloads/UIO/user/cif-* To compile this driver as a module, choose M here: the module will be called uio_cif. config UIO_PDRV tristate "Userspace I/O platform driver" help Generic platform driver for Userspace I/O devices. If you don't know what to do here, say N. 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_SMX tristate "SMX cryptengine UIO interface" help Userspace IO interface to the Cryptography engine found on the Nias Digital SMX boards. These will be available from Q4 2008 from http://www.niasdigital.com. The userspace part of this driver will be released under the GPL at the same time as the hardware and will be able to be downloaded from the same site. If you compile this as a module, it will be called uio_smx. 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" 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 default n 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. endif
