After loading the module, the marvell-cesa ahash show up with "selftest : passed". But whether they REALLY were tested, I can't say. # cat /proc/crypto name : crc32c driver : crc32c-generic module : kernel priority : 100 refcnt : 1 selftest : passed internal : no type : shash blocksize : 1 digestsize : 4 # modprobe marvell-cesa # cat /proc/crypto name : hmac(sha256) driver : mv-hmac-sha256 module : marvell_cesa priority : 0 refcnt : 1 selftest : passed internal : no type : ahash async : yes blocksize : 64 digestsize : 32 name : hmac(sha1) driver : mv-hmac-sha1 module : marvell_cesa priority : 0 refcnt : 1 selftest : passed internal : no type : ahash async : yes blocksize : 64 digestsize : 20 name : hmac(md5) driver : mv-hmac-md5 module : marvell_cesa priority : 0 refcnt : 1 selftest : passed internal : no type : ahash async : yes blocksize : 64 digestsize : 16 name : sha256 driver : mv-sha256 module : marvell_cesa priority : 0 refcnt : 1 selftest : passed internal : no type : ahash async : yes blocksize : 64 digestsize : 32 name : sha1 driver : mv-sha1 module : marvell_cesa priority : 0 refcnt : 1 selftest : passed internal : no type : ahash async : yes blocksize : 64 digestsize : 20 name : md5 driver : mv-md5 module : marvell_cesa priority : 0 refcnt : 1 selftest : passed internal : no type : ahash async : yes blocksize : 64 digestsize : 16 name : cbc(aes) driver : mv-cbc-aes module : marvell_cesa priority : 300 refcnt : 1 selftest : passed internal : no type : skcipher async : yes blocksize : 16 min keysize : 16 max keysize : 32 ivsize : 16 chunksize : 16 walksize : 16 statesize : 0 name : ecb(aes) driver : mv-ecb-aes module : marvell_cesa priority : 300 refcnt : 1 selftest : passed internal : no type : skcipher async : yes blocksize : 16 min keysize : 16 max keysize : 32 ivsize : 0 chunksize : 16 walksize : 16 statesize : 0 name : cbc(des3_ede) driver : mv-cbc-des3-ede module : marvell_cesa priority : 300 refcnt : 1 selftest : passed internal : no type : skcipher async : yes blocksize : 8 min keysize : 24 max keysize : 24 ivsize : 8 chunksize : 8 walksize : 8 statesize : 0 name : ecb(des3_ede) driver : mv-ecb-des3-ede module : marvell_cesa priority : 300 refcnt : 1 selftest : passed internal : no type : skcipher async : yes blocksize : 8 min keysize : 24 max keysize : 24 ivsize : 0 chunksize : 8 walksize : 8 statesize : 0 name : cbc(des) driver : mv-cbc-des module : marvell_cesa priority : 300 refcnt : 1 selftest : passed internal : no type : skcipher async : yes blocksize : 8 min keysize : 8 max keysize : 8 ivsize : 8 chunksize : 8 walksize : 8 statesize : 0 name : ecb(des) driver : mv-ecb-des module : marvell_cesa priority : 300 refcnt : 1 selftest : passed internal : no type : skcipher async : yes blocksize : 8 min keysize : 8 max keysize : 8 ivsize : 0 chunksize : 8 walksize : 8 statesize : 0 name : crc32c driver : crc32c-generic module : kernel priority : 100 refcnt : 1 selftest : passed internal : no type : shash blocksize : 1 digestsize : 4 # dmesg | tail [ 4.883366] mv88e6085 f1072004.mdio-mii:10 lan2: configuring for phy/gmii link mode [ 4.884517] br0: port 3(lan4) entered blocking state [ 4.884527] br0: port 3(lan4) entered forwarding state [ 88.867746] marvell-cesa f1090000.crypto: CESA device successfully registered [ 89.034292] alg: skcipher: skipping comparison tests for mv-cbc-des because cbc(des-generic) is unavailable [ 89.045265] alg: skcipher: skipping comparison tests for mv-cbc-des3-ede because cbc(des3_ede-generic) is unavailable [ 89.052456] alg: skcipher: skipping comparison tests for mv-cbc-aes because cbc(aes-generic) is unavailable [ 89.099763] alg: skcipher: skipping comparison tests for mv-ecb-aes because ecb(aes-generic) is unavailable [ 89.099819] alg: skcipher: skipping comparison tests for mv-ecb-des3-ede because ecb(des3_ede-generic) is unavailable [ 89.099908] alg: skcipher: skipping comparison tests for mv-ecb-des because ecb(des-generic) is unavailable
