GLXSB(4)             NetBSD/i386 Kernel Interfaces Manual             GLXSB(4)


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 pro-
     cessors.  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).


SEE ALSO

     crypto(4), i386/intro(4), pci(4), random(4), crypto(9)


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.
