- For install:
- kvmclock-kmod is experimental and currently under development. This port
provides an easy and quick method for users to test this code for early
testing, feedback and bug reports.
This driver enables FreeBSD to use a more efficient paravirtualized
hardware clock, instead of emulating one, or abusing hypervisor
interrupts, when running as a virtualized OS under Linux KVM
(Kernel-based Virtual Machine).
Usage:
# kldload kvmclock
# sysctl kern.timecounter
kern.timecounter.choice: kvmclock(975) i8254(0) ...
kern.timecounter.hardware: kvmclock

Remove WWW entries moved into port Makefiles
Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles
It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.
Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.
There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.
