New Revision: 266413
URL: http://svnweb.freebsd.org/changeset/base/266413
Log:
Initial work on evdev support. Includes evdev chardev driver with
basic ioctls support (enough to run X with evdev-driven mouse) and
a modified ums(4) driver reporting to evdev layer.
Userspace interface headers (input.h and uinput.h) are for now
borrowed from Linux and adapted to BSD ioctl specifics.
