6 n2rng - Ultra-SPARC T2 random number generator device driver
7
9 The n2rng device driver is a multi-threaded, loadable hardware driver
10 supporting hardware assisted random numbers. This support is built into
11 the Ultra-SPARC T2 CMT processor.
12
13
14 The n2rng driver requires the presence of the Solaris Cryptographic
15 Framework to enable applications and kernel clients to access the pro‐
16 vided services.
17
19 You configure the n2rng driver by defining properties in /plat‐
20 form/sun4v/kernel/drv/n2cp.conf which override the default settings.
21 The following property is supported:
22
23 nostats Disables the generation of statistics. The
24 nostats property may be used to help pre‐
25 vent traffic analysis, however, this may
26 inhibit support personnel.
27
28
30 Solaris crypto drivers must implement statistics variables. Statistics
31 are reported by n2rng using the kstat(7D) and kstat(9S) mechanisms.
32 The n2rng driver maintains the following statistics:
33
34 status Status (online, offline, fail) of RNG
35 device.
36
37
38 rngjobs Number of requests for random data.
39
40
41 rngbytes Number of bytes read from the RNG device.
42
43
45 The n2rng driver tallies a set of kernel driver statistics when in
46 the Control domain. Statistics are reported by n2rng using the
47 kstat(7D) and kstat(9S) mechanisms. All statistics are maintained as
48 unsigned, and all are 64 bits.
