glxsb
— Geode LX
Security Block crypto accelerator
glxsb* at pci?
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).
The glxsb
device first appeared in
NetBSD 4.0.
The glxsb
driver was written for
OpenBSD by Tom Cosgrove. It
was ported to NetBSD by
Jared D. McNeill
<jmcneill@NetBSD.org>.
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.
