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.
