|
|
.Sh SYNOPSIS
|
|
.Cd "glxsb* at pci?"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver supports the security block of the Geode LX series processors.
|
|
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.
|
|
.Pp
|
|
.Nm
|
|
also supports acceleration of AES-CBC operations for
|
|
.Xr crypto 4 .

.Sh HISTORY
|
|
The

|
|
device first appeared in
|
|
.Nx 5.0 .
|
|
.Sh AUTHORS
|
|
The
|
|
.Nm
|
|
driver was written for
|
|
.Ox
|
|
by
|
|
.An Tom Cosgrove .
|
|
It was ported to
|
|
.Nx
|
|
by
|
|
.An Jared D. McNeill Aq jmcneill@NetBSD.org .
|
|
.Sh BUGS
|
|
The
|
|
.Nm
|
|
driver only provides random numbers and AES acceleration.
|
|
Since it does not provide HMACs, IPSec will not currently use it;
|
|
it will however be used by OpenSSH.
