2008-07-21UIO: Add write function to allow irq maskingHans J. Koch
Sometimes it is necessary to enable/disable the interrupt of a UIO device from the userspace part of the driver. With this patch, the UIO kernel driver can implement an "irqcontrol()" function that does this. Userspace can write an s32 value to /dev/uioX (usually 0 or 1 to turn the irq off or on). The UIO core will then call the driver's irqcontrol function. Signed-off-by: Hans J.

2008-01-24UIO: fix kobject usageGreg Kroah-Hartman
The uio kobject code is "wierd". This patch should hopefully fix it up to be sane and not leak memory anymore.

2007-07-18UIO: Add the User IO core codeHans J. Koch
This interface allows the ability to write the majority of a driver in userspace with only a very small shell of a driver in the kernel itself. It uses a char device and sysfs to interact with a userspace process to process interrupts and control memory accesses. See the docbook documentation for more details on how to use this interface.
