I tested the latest cryptodev tree on my haswell machine and this is what I see: [ 40.402834] modprobe tcrypt mode=422 [ 40.403105] testing speed of multibuffer sha1 (sha1_mb) [ 40.403108] test 0 ( 16 byte blocks, 16 bytes per update, 1 updates): 32271 cycles/operation, 252 cycles/byte [ 40.403118] At least one hashing failed ret=-115 [ 43.218712] modprobe tcrypt mode=423 [ 43.218712] testing speed of multibuffer sha256 (sha256_mb) [ 43.218715] test 0 ( 16 byte blocks, 16 bytes per update, 1 updates): 106965 cycles/operation, 835 cycles/byte [ 43.218747] At least one hashing failed ret=-115 [ 45.346657] modprobe tcrypt mode=424 [ 45.346657] testing speed of multibuffer sha512 (sha512_mb) [ 45.346660] test 0 ( 16 byte blocks, 16 bytes per update, 1 updates): 43179 cycles/operation, 337 cycles/byte [ 45.346673] At least one hashing failed ret=-115 Don't think this is expected, is it? This is the patch which might have an issue? 72259deb3a9f2c07d18d71d7c9356754e7d88369 Thanks, Megha On Wed, 2016-06-29 at 10:28 +0200, Krzysztof Kozlowski wrote: > On 06/29/2016 10:19 AM, Herbert Xu wrote: > > On Wed, Jun 29, 2016 at 10:16:10AM +0200, Krzysztof Kozlowski wrote: > >> > >> Seems to work fine except: > >> 1.
