It is a pretty hard to come up with even a theoretical concept of a device driver which would always fail open and close with ENODEV. Change the defaults to be nullopen() and nullclose() which simply does nothing. Remove explicit initializations to these from the drivers which already used them. Be less confusing in a comment. 2003-09-05T11:05:41Z Poul-Henning Kamp phk@FreeBSD.org 2003-09-05T11:05:41Z urn:sha1:4740a0e7f2de5e0efca92d37a2c89cc9d8deb1c9 Use __FBSDID(). 2003-08-24T17:55:58Z David E.

Make the interrupt both MPSAFE and FAST, at 610 interrupts a second, and a max time to service of 5 msec, we brake for nobody. Use kernel thread to accumulate into the 25 possible wave signals. Use #ifdef _KERNEL to let .c file double as .h file defining the ioctls. Add a rudimentary but working driver for the Adlink "NuDaq PCI-9812". 2003-04-04T18:53:04Z Poul-Henning Kamp phk@FreeBSD.org 2003-04-04T18:53:04Z urn:sha1:fb89eb1ed7100137de8c184da2f002e664f4cd15 This is a 4 channel 20 msps 12 bit ADC card.
