# 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).

# 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.
