UIO: Remove SMX Cryptengine driver

2010-03-08T01:04:51+00:00

Ben Nizette, the author of this driver, told me in a private mail that this
project has been cancelled. He suggested to remove the driver for now, and
will come back with a new version should the hardware really exist.
This patch completely removes the driver.

UIO: minor Kconfig fixes

2010-03-08T01:04:51+00:00

Two trivial fixes for the Userspace IO Kconfig file:
1) uio_sercos3 is a PCI driver, so let it depend on PCI.
2) "default n" under UIO_PCI_GENERIC is luxury since it is already the default.

UIO: Add a driver for Hilscher netX-based fieldbus cards

2010-03-08T01:04:50+00:00

This patch adds a Userspace IO driver for netX-based fieldbus cards by
Hilscher (see http://www.hilscher.com). ATM, cifX and comX cards are
supported. The userspace part for this driver is provided by Hilscher
and should come with the card.
The driver is in use for several months now and has been tested by
people at Hilscher and Linutronix.

uio: add generic driver for PCI 2.3 devices

2009-09-15T16:50:48+00:00

This adds a generic uio driver that can bind to any PCI device.  First
user will be virtualization where a qemu userspace process needs to give
guest OS access to the device.

Interrupts are handled using the Interrupt Disable bit in the PCI
command register and Interrupt Status bit in the PCI status register.
All devices compliant to PCI 2.3 (circa 2002) and all compliant PCI
Express devices should support these bits.  Driver detects this support,
and won't bind to devices which do not support the Interrupt Disable Bit
in the command register.

It's expected that more features of interest to virtualization will be
added to this driver in the future. Possibilities are: mmap for device
resources, MSI/MSI-X, eventfd (to interface with kvm), iommu.

UIO: remove 'default n' from Kconfig

'default n' is the default, there is no need for these lines.

uio: add the uio_aec driver

2009-03-24T23:38:24+00:00

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.

uioport is designed to be a setuid program and checks the permissions of
the /dev/uio* node and if the user has write permissions it will use
iopl and out*/in* to access the device.

UIO: add automata sercos3 pci card support

2008-10-16T16:24:53+00:00

Here is a new version of the patch to support the Automata Sercos III
PCI card driver. I now check that the IRQ is enabled before accepting
the interrupt.

I still use a logical OR to store the enabled interrupts and I've
added a second use of a logical OR when restoring the enabled
interrupts. I added an explanation of why I do this in comments at the
top of the source file.

Since I use a logical OR, I also removed the extra checks if the
Interrupt Enable Register and ier0_cache are 0.

UIO: generic irq handling for some uio platform devices

2008-08-21T17:15:39+00:00

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: add generic UIO platform driver

2008-07-22T04:54:55+00:00

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: fix UIO Kconfig dependencies

2008-07-22T04:54:53+00:00

ae210f188614bb3d1ee3f19c64e28e3cdd44877c introduced a big "if UIO"/"endif"
where all uio drivers are defined.  So know there is no need for them to
depend explicitly on UIO.
