UIO: Hilscher CIF card driver this is a patch that adds support for Hilscher CIF DeviceNet and Profibus cards. I tested it on a Kontron CPX board, and Thomas reviewed it. You can find the user space part here: http://www.osadl.org/projects/downloads/UIO/user/cif-0.1.0.tar.gz Notes: cif_api.c is the main file you want to look at. It contains the functions to open, close, mmap and so on. cif_dps.c adds functions specific to Profibus cards, and cif_dn.c contains functions for DeviceNet cards. cif.c is a universal playground, it's just a small test program. The user space part of this UIO driver is still work in progress, and not everything is tested yet. At the moment, the thread in cif_api.c contains some code that artificially makes the card generate interrupts, this was added for testing and will be removed later. But the driver already contains all the functions needed for useful operation, so it gives a good idea of how such a thing looks like. For comparison, here's what you get from the manufacturer (www.hilscher.com) when you ask for a Linux 2.6 driver: http://www.tglx.de/private/hjk/cif-orig-2.6.tar.bz2 WARNING: Don't look at the code for too long, you might become sick :-) Signed-off-by: Hans-Jürgen Koch <hjk@linutronix.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

UIO: add generic UIO platform driver This patch adds a generic UIO platform driver. It eliminates the need for a dedicated kernel module for simple platform devices. Users only need to implement their irq handler in platform code and fill a struct uio_info there. This helps avoiding code duplication as UIO platform drivers often share a lot of common code.

UIO: generic irq handling for some uio platform devices This is V3 of uio_pdrv_genirq.c, a platform driver for UIO with generic IRQ handling code. This driver is very similar to the regular UIO platform driver, but is only suitable for devices that are connected to the interrupt controller using unique interrupt lines. The uio_pdrv_genirq driver includes generic interrupt handling code which disables the serviced interrupt in the interrupt controller and makes the user space driver responsible for acknowledging the interrupt in the device and reenabling the interrupt in the interrupt controller. Shared interrupts are not supported since the in-kernel interrupt handler will disable the interrupt line in the interrupt controller, and in a shared interrupt configuration this will stop other devices from delivering interrupts.

UIO: Implement a UIO interface for the SMX Cryptengine This patch implements a UIO interface for the SMX Cryptengine. The Cryptengine found on the Nias Digital SMX board is best suited for a UIO interface. It is not wired in to the cryptographic API as the engine handles it's own keys, algorithms, everything. All that we know about is that if there's room in the buffer, you can write data to it and when there's data ready, you read it out again. There isn't necessarily even any direct correlation between data going in and data coming out again, the engine may consume or generate data all on its own. This driver is for proprietary hardware but we're always told to submit the drivers anyway; here you are. :-) This is version 4 of this patch and addresses all issues raised by Hans-Jürgen Koch and Paul Mundt in their reviews. Slightly altered is Paul's suggestion to use DRV_NAME and DRV_VERSION as the UIO version and name. While at the moment they are the same, there is no reason for them to stay that way. Nevertheless we now at least provide a MODULE_VERSION macro to keep modinfo happy.
