Hi, I installed cryptodev 1.7 on my Debian box running on Marvell Feroceon processor (featuring mv_cesa hardware accelerator). I'm running debian wheezy with openssl_1.0.1e (with enabled cryptodev and the two recommended patches) and kernel 3.16 from backports.
My problem is that SHA1 acceleration doesn't seem to work, while it should be supported by the engine. >From /proc/crypto: name : sha1 driver : mv-sha1 module : mv_cesa priority : 300 refcnt : 1 selftest : unknown type : ahash async : yes blocksize : 64 digestsize : 20 If I run ./sha_speed in tests I always get the sha1-asm fallback driver, instead of mv-sha1. cryptodev-linux-1.7/tests# ./sha_speed Testing SHA1 Hash: requested hash CRYPTO_SHA1, got sha1 with driver sha1-asm Similarly, testing with openssl -evp speed sha1 does not show any improvement. If I set verbosity to 3, that's what I get in dmesg when attempting sha1: [222287.705223] cryptodev: sha_speed[6709] (cryptodev_open:480): allocated new item at df5eb260 [14 more] [222287.705331] cryptodev: sha_speed[6709] (cryptodev_open:480): allocated new item at df5eb3e0 [222287.705338] cryptodev: sha_speed[6709] (cryptodev_open:485): Cryptodev handle initialised, 16 elements in queue [222287.721595] cryptodev: sha_speed[6709] (crypto_create_session:284): got alignmask 0 [222287.721608] cryptodev: sha_speed[6709] (crypto_create_session:287): preallocating for 32 user pages [222304.213713] cryptodev: sha_speed[6709] (get_userbuf:186): failed to get user pages for data input [222304.222739] cryptodev: sha_speed[6709] (__crypto_run_zc:174): Error getting user pages.

I would appreciate hints on how I should get to the bottom of this. Thanks, Jan
