Currently just uses the RNG; AES support to be added later.

+.Sh NAME
+.Nm glxsb
+.Nd Geode LX Security Block device
+.Sh SYNOPSIS
+.Cd "glxsb* at pci?"
+.Sh DESCRIPTION
+The
+.Nm
+driver supports the security block of the Geode LX series processors.
+.Pp
+The Geode LX is a member of the AMD Geode family
+of integrated x86 system chips.
+.Pp
+Driven by periodic checks for available data from the generator,
+.Nm
+supplies entropy to the
+.Xr random 4
+driver for common usage.
+.Sh SEE ALSO
+.Xr random 4
+.Sh HISTORY
+Support for the
+.Nm
+was added in
+.Ox 4.1 .
+.Sh AUTHORS
+The
+.Nm
+driver was written by
+.An Tom Cosgrove .
+.Sh BUGS
+The
+.Nm
+driver does not yet use the AES acceleration provided by the security block;
+it only uses the random number generator.
