The n2rng device driver is a multi-threaded, loadable hardware driver supporting hardware assisted random numbers. This support is built into the Ultra-SPARC T2 CMT processor.
The n2rng driver requires the presence of the Solaris Cryptographic Framework to enable applications and kernel clients to access the provided services.
You configure the n2rng driver by defining properties in /platform/sun4v/kernel/drv/n2cp.conf which override the default settings. The following property is supported:
Solaris crypto drivers must implement statistics variables. Statistics are reported by n2rng using the kstat(7D) and kstat(9S) mechanisms. The n2rng driver maintains the following statistics:
The n2rng driver tallies a set of kernel driver statistics when in the Control domain. Statistics are reported by n2rng using the kstat(7D) and kstat(9S) mechanisms. All statistics are maintained as unsigned, and all are 64 bits.
