To compile this driver into the kernel,
place the following lines in your
kernel configuration file:
device cryptodevice glxsb
Alternatively, to load the driver as a
module at boot time, place the following line in
loader.conf5:
glxsb_load="YES"
DESCRIPTION
The
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,
supplies entropy to the
random(4)
driver for common usage.
also supports acceleration of AES-128-CBC operations for
crypto(4).
It also registers itself to accelerate other HMAC algorithms, although
there is no hardware acceleration for those algorithms.
This is only needed so
can work with
ipsec(4).
CAVEAT
The
crypto(9)
framework will fail to open the crypto session on the device if the AES
key's length is != 128 bits.
This prevents the use of the
device driver with AES keys of length != 128 bits.
