and the "kernel.tar.Z" distribution on louie.udel.edu, which is older than
xntp 3.4y or 3.5a, but contains newer kernel source fragments.
This commit adds support for a new kernel configuration option, NTP.
If NTP is selected, then the system clock should be run at "HZ", which
must be defined at compile time to be one value from:
60, 64, 100, 128, 256, 512, 1024.
Powers of 2 are ideal; 60 and 100 are supported but are marginally less
accurate.
If NTP is not configured, there should be no change in behavior relative
to pre-NTP kernels.
These changes have been tested extensively with xntpd 3.4y on a decstation;
almost identical kernel mods work on an i386. No pulse-per-second (PPS)
line discipline support is included, due to unavailability of hardware
to test it.
With this in-kernel PLL support for NetBSD, both xntp 3.4y and xntp
3.5a user-level code need minor changes. xntp's prototype for
syscall() is correct for FreeBSD, but not for NetBSD.
planned changes in other sections of code.
(2) expands the use of config_found() in tcattach() in-line, so that
tcsubmatch can be invoked there, rather than being invoked by
individual drivers.
(3) tcbus_attach_args now includes a turbochannel speed flag.
(4) compare a string in tcbus_attach_args against tc bus driver name,
to better allow attachment of multiple busses to the same parent.
versions work correctly; at some point between then and the immediately
preceding revisions, the "stylistic" changes to one (or both) stdarg.h
and varargs.h broke passing doubles to printf().
a dca-specific constant. For now, hardwire standalone DCA console
at select code 9 (which is what the old constant expanded to). Really
should make the way the bootblock console is probed look just like how
the kernel console is probed.
send_to_kdc.c will try the kerberos4 port first, and then the kerberos
port. send_to_kdc.c will connect() to the socket so that it retries
quickly if it gets a port unreachable message. Also, don't rely on
select() not modifying the timeout parameter.
