registers are control bits or depending on the model contain additional time bits with a different meaning than the lower ones. In order to only read the desired time bits and not change the upper bits on write use appropriate masks in the gettime and settime function respectively. Due to the polarity of the stop oscillator bit and the fact that the century bits aren't used on sparc64 not masking them didn't cause problems so far. - Fix two off-by-one errors in the handling of the day of week. The genclock code represents the dow as 0 - 6 with 0 being Sunday but the mk48txx use 1 - 7 with 1 being Sunday. In the settime function when writing the dow to the clock the range wasn't adjusted accordingly but the clock apparently played along nicely otherwise the second bug in the gettime function which mapped 1 - 7 to 0 - 6 but with 0 meaning Saturday would have been triggered. Fixing these makes the date being stored in the same format Sun/Solaris uses and cures the "Invalid time in real time clock. Check and reset the date immediately!" when the date was set under Solaris prior to booting FreeBSD/sparc64. [1] Looking at other clock drivers/code e.g. FreeBSD/alpha the former "bug", i.e. storing the dow as 0 - 6 even when the clock uses 1 - 7, seems to be common but might be on purpose for compatibility when multi-booting with other OS which do the same. So it might make sense to add a flag to handle the dow off-by-one for use of this driver on platforms other than sparc64. - Check the state of the battery on mk48txx that support this in the attach function. - Add a note that use of the century bit should be implemented but isn't required at the moment because it isn't used on sparc64.

This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``buildkernel'' and ``installkernel'' targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you might need to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/<arch>/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
