# Download the driver package from github.com
$ wget https://github.com/slaclab/aes-stream-drivers/archive/v1.0.1.tar.gz
$ tar -zxvf v1.0.1.tar.gz
# go to the pgpcard directory and build the driver:
$ cd aes-stream-drivers-1.0.1/pgpcard/driver/
$ make
# You will end up with a file pgpcard.ko
# Load the driver as root:
$ sudo insmod pgpcard.ko
# Update the permissions to the device such that
# you won't need sudo access to run the software application
$ sudo chmod 666 /dev/pgpcard_*
# Verify the card loaded:
$ cat /proc/pgpcard_0
# Scroll up and you will see a dump of information for "lane 0" like this
