[Ocf-linux-users] No performances improvment with AMD Geode

[Adam C. (Le_Vert) <ga...@le...>]

Hello,

Could you please help me to figure out what's wrong with my OCF setup ?
Here are some useful commands run on the Geode:

Loaded kernel modules:
gandalf@alix:~$ lsmod | grep -e cry -e oc
cryptodev              13988  3
crypto_null             2624  0
cryptosoft             12136  0
ocf                    28984  2 cryptodev,cryptosoft

Device node:
gandalf@alix:~$ ls -lah /dev/crypto
crw-rw-rw- 1 root root 10, 70 jun  2 17:11 /dev/crypto

OpenSSL engines:
gandalf@alix:~$ openssl engine
(cryptodev) BSD cryptodev engine
(padlock) VIA PadLock (no-RNG, no-ACE)
(dynamic) Dynamic engine loading support

Speed (without cryptodev):
gandalf@alix:~$ openssl speed -evp aes128 -elapsed
