Hello,

I'm playing with a miniPCI hifn card on some embedded hardware (WRAP /
pcengines.ch) currently running NetBSD 4.0_BETA2.

[...]
hifn0 at pci0 dev 13 function 0: Hifn 7955, rev. 0
hifn0: 3DES/AES, 32KB dram, interrupting at irq 12
[...]

I ran openssl speed -engine cryptodev aes-256-cbc (it's just a guess i'm =
not
sure cryptodev is the correct engine, i see ubsec but no hifn engine)

here are the result :

with hifn(4) :

root@earthprout:~ # openssl speed -engine cryptodev aes-256-cbc
engine "cryptodev" set.

without hifn(4) (on the same hardware configuration) :

root@airprout:~ # openssl speed -engine cryptodev aes-256-cbc
engine "cryptodev" set.

0.06k

so without hifn(4) is often faster and there is no "unloading" of the CPU=
 on the
hifn(4) card, the load is identical on both.

checking with ktruss and looking at crypto(4), i see no ioctl(CIOCCRYPT) =
during
the openssl speed test, am i doing things right ? do I miss something ?

Regards,
Eric.
