Hi,
I have a AMD Geode LX800 based system (PC Engines ALIX 2C3) and am trying to
use a HIFN 7955 (Soekris VPN1411) crypto card to improve OpenSSL performance
(for SFTP and OpenVPN).
However after installing the HIFN card I don't seem to get any performance
gain, and all the crypto still seems to be happening in software.
# fstat /dev/crypto
USER CMD PID FD MOUNT INUM MODE R/W SZ|DV NAME
root sshd 10817 3 / 79183 crw-rw-rw- rw crypto
/dev/crypto
root sshd 28851 3 / 79183 crw-rw-rw- rw crypto
/dev/crypto
root sshd 2345 3 / 79183 crw-rw-rw- rw crypto
/dev/crypto
_openvpn openvpn 15800 5 / 79183 crw-rw-rw- rw crypto
/dev/crypto
It appears that sshd & openvpn are using /dev/crypto, is there a way to tell if
this is actually using the HIFN card?
I thought that the system might be using the built in crypto in the AMD Geode
CPU instead of the HIFN and have used "config -e -o bsd.new /bsd" to disable
glxsb (glxsb0 at pci0 dev 1 function 2 "AMD Geode LX Crypto" rev 0x00: RNG AES)
in the kernel, and booted the new kernel config however this makes no
difference.
