SYNOPSIS
vrng0 at vbus?
DESCRIPTION
The vrng driver provides support for the random number generation service
provided by the UltraSPARC Hypervisor as found on sun4v systems.
Driven by periodic checks for available data from the generator, vrng
supplies entropy to the random(4) driver for common usage.

AUTHORS
The vrng driver was written by Mark Kettenis <kettenis@openbsd.org>.
BUGS
The vrng driver should probably do periodic ``health checks'' when
running in a Trusted Domain, but currently does not.
