Release Notes
The following changes are in the version 3.5 distribution relative to
the previous 3.4y version.
- Please note the scripts for configuring radio clock drivers do
not work. See the building and installing documentation for specific
information.
- The documentation has been completely reworked in HTML format
suitable for web browsing.
- The automatic build procedure has been improved to
- support the line disciplines, streams modules and precision
time kernel modifications. These are controlled by the presence of
certain system-dependent header files in the
/usr/include/sys directory.
- include by default all reference clock drivers known to work
with each combination of hardware and operating system. (The particular
defaults are specified in the
../machines files for each
machine.)
- activate precision time kernel modifications by default if
detected by the build procedure. (Previous versions required an
undocumented addition to the
ntp.drift file in order to
activate these modifications.)
- Three TrueTime reference clock drivers, which did slightly
different things with each model, have been replaced with one driver
(type 5) that works with all models. Two new reference clock drivers
have been added, one for the Bancomm IRIG interface, the other for the
TrueTime GPS-VME interface. Both of these work only with the HP
architecture.
- There is a new
pps option to the xntpdc
program and configuration file enable/disable command,
which enables or disables the PPS precision time control signal for both
the PPS clock driver and kernel PPS interface, where available. This is
primarily intended for situations where external equipment has
malfunctioned or the signal has become excessively noisy.
- The
precision configuration file command and
xntpdc command have been removed; the precision variable
quantity is now determined automatically and cannot be changed.
- The
authenticate and monitor commands
in xntpdc have been removed; the functions formerly
provided by these commands are now provided by the enable
and disable commands.
- Fixed minor problems peculiar to different machines and system
environments. Fixed minor problem in the PPS interfaces and mitigation
rules. See the ./patches directory for details.
Version 3.5 has been compiled and run on at least the following
machines, operating systems and compilers. In all known cases, if the
gcc compiler eats it with some success, the cc compiler also enjoys the
meal; the converse is not always true. Note that, while all clock
drivers have been compiled, only certain ones have been tested with each
machine and operating system.
