Thanks Yoan. Can you please confirm that you tested the driver on the platform you reported using a kernel with CONFIG_CRYPTO_MANAGER_DISABLE_TESTS not set and CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y and the self test is passing? You can check it by running $ cat /proc/crypto | grep -B 4 passed | grep -e "qat_\|qat-" | sort This should report: driver : qat_aes_cbc driver : qat_aes_cbc_hmac_sha1 driver : qat_aes_cbc_hmac_sha256 driver : qat_aes_cbc_hmac_sha512 driver : qat_aes_ctr driver : qat_aes_xts driver : qat-dh driver : qat-rsa Note that if you are using the HEAD of cryptodev-2.6 you will have to either revert 8893d27ffcaf6ec6267038a177cb87bcde4dd3de or apply https://patchwork.kernel.org/project/linux-crypto/list/?series=639755 as the algorithms have been temporarily disabled.
