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.
