/*
|
|
* Ported to 386bsd Oct 17, 1992
|
|
* Sandi Donno, Computer Science, University of Cape Town, South Africa
|
|
* Please send bug reports to sandi@cs.uct.ac.za
|
|
*
|
|
* Thanks are also due to Rick Macklem, rick@snowhite.cis.uoguelph.ca -
|
|
* although I was only partially successful in getting the alpha release
|
|
* of his "driver for the Logitech and ATI Inport Bus mice for use with
|
|
* 386bsd and the X386 port" to work with my Microsoft mouse, I nevertheless
|
|
* found his code to be an invaluable reference when porting this driver
|
|
* to 386bsd.
|
|
*
|
|
* Further modifications for latest 386BSD+patchkit and port to NetBSD,
|
|
* Andrew Herbert <andrew@werple.apana.org.au> - 8 June 1993
|
|
*
|
|
* Cloned from the Microsoft Bus Mouse driver, also by Erik Forsberg, by
|
|
* Andrew Herbert - 12 June 1993
|
|
*
|
|
* Modified for PS/2 mouse by Charles Hannum <mycroft@ai.mit.edu>
|
|
* - 13 June 1993
|
|
*
|
|
* Modified for PS/2 AUX mouse by Shoji Yuen <yuen@nuie.nagoya-u.ac.jp>
|
|
* - 24 October 1993
|
|
*
|
|
* Hardware access routines and probe logic rewritten by
|
|
* Kazutaka Yokota <yokota@zodiac.mech.utsunomiya-u.ac.jp>
|
|
* - 3, 14, 22 October 1996.
|
|
* - 12 November 1996. IOCTLs and rearranging `psmread', `psmioctl'...
|
|
* - 14, 30 November 1996. Uses `kbdio.c'.
|
|
* - 13 December 1996. Uses queuing version of `kbdio.c'.
|
|
* - January/February 1997. Tweaked probe logic for
|
|
* HiNote UltraII/Latitude/Armada laptops.
|
|
* - 30 July 1997. Added APM support.
|
|
* - 5 March 1997. Defined driver configuration flags (PSM_CONFIG_XXX).
|
|
* Improved sync check logic.
|
|
* Vendor specific support routines.
