Re: [Ocf-linux-users] hardware acceleration question

[Max <ma...@da...>]

Thank you for support David.

I successfully moved driver aes-7108 to ocf-linux-20060331 and build
appropriate crypto-tools.

It's loaded ok:

~ # dmesg|grep 71
Peripheral DMA: Chip 0x7108
cypher_7108_crypto_init(8011670c)
7108: AES @ 0xbb500100 (0x1b500100 phys) CTR mode

but openssl still failed to recognize it:

~ # openssl engine
Hardware
cryptodev RSA
cryptodev DSA
cryptodev DH
eng_cryptodev.c:1334 CIOCASYMFEAT - failure
(cryptodev) BSD cryptodev engine
(dynamic) Dynamic engine loading support

However cryptodev itself is present and usable:

~ # openssl speed -elapsed -evp aes128 -engine cryptodev -cpu
Hardware
cryptodev RSA
cryptodev DSA
cryptodev DH
eng_cryptodev.c:1334 CIOCASYMFEAT - failure
engine "cryptodev" set.

It looks like ocf driver aes-7108 is not used at all.

When I'm trying to run

~ # cryptotest -v
cipher 3des keylen 24
CIOCGSESSION: Invalid argument

/dev/crypto disappear with no erros in dmesg.

After this 

~ # openssl engine
ENGINE_load: failed to load cryptodev
ENGINE_load: failed to load cryptodev
(dynamic) Dynamic engine loading support

failed to find it.

I'll try to have a closer look at driver's source code and crypto-tools
but right now it looks like there is either something wrong with ocf and
\or driver (when called by cryptotest) or openssl (which fails to call
it).

Any hints on what could be done next would be greatly appreciated.

best regards,
Max.
