NAME
glxsb —
Geode LX Security Block crypto
accelerator
SYNOPSIS
glxsb* at pci?
DESCRIPTION
The
glxsb 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.
Driven by periodic checks for available data from the generator,
glxsb supplies entropy to the
random(4) driver for common
usage.
glxsb also supports acceleration of AES-CBC operations for
crypto(4).

HISTORY
The
glxsb device first appeared in
NetBSD
4.0.
AUTHORS
The
glxsb driver was written for
OpenBSD by
Tom Cosgrove. It
was ported to
NetBSD by
Jared D. McNeill
<
jmcneill@NetBSD.org>.
BUGS
The
glxsb 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.
