2008-07-21uio-howto.tmpl: use unique output namesMike Frysinger
The Userspace I/O HOWTO template sets two different sections with the same html output name (about.html). This clearly won't work, so change the first one to a unique "aboutthis.html" to prevent clobbering. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Acked-by: Hans J.

2008-07-21uio-howto.tmpl: use standard copyright/legal markingsMike Frysinger
The Userspace I/O HOWTO document uses straight <sect1> tags and plain text to describe copyright/legal information. It should instead use the <copyright> and <legalnotice> tags like all other documents in the kernel. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Acked-by: Hans J.

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.

2007-11-28UIO: fix up the UIO documentationHans J Koch
Remove references to the old uio_dummy demo module from UIO documentation. Add a small paragraph to make it clearer that UIO is not a universal driver interface. Signed-off-by: Hans J Koch <hjk@linutronix.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-08-09remove dubious legal statment from uio-howtoAlan Cox
UIO currently contains a rather dubious statement which wants removing. The actual questions around whether user space code that depends tightly on kernel GPL code designed to co-work with it are derivative works of the kernel is extremely complex, and since we don't have space for either a masters length essay on legal issues or need to start flamewars lets simply remove the comment and leave law to lawyers Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Linus Torvalds <tovalds@linux-foundation.org>
