simonb-timecounters branch: testers wanted
Simon Burge and Frank Kardel are working on a port of FreeBSD's
timecounter implementations to NetBSD. For those wondering,
this is about `` an architecture-independent
implementation of a binary timescale using whatever hardware support
is at hand for tracking time. The binary timescale converts using
simple multiplication to canonical timescales based on micro- or
nano-seconds and can interface seamlessly to the NTP PLL/FLL
facilities for clock synchronisation. Timecounters are implemented
using lock-less stable-storage based primitives which scale
efficiently in SMP systems.'' (citing
Poul-Henning Kamp's paper).
Their work
is progressing, and Frank and Simon are now looking for testers
of the interface together with the latest NTP snapshot. See
their mail to tech-kern@
for details.
