ZFS ZFS dataset encryption and AES-NI

[monaco87]

Hi,

Is there any way to verify that my native encryption ZFS datasets are benefiting from CPU AES-NI support? I can't see anything in dmesg regarding CPU capabilities, though installed processor is Intel Xeon CPU E5-2620 v4 which supports AES-NI instructions.

Thanks

dmesg | grep -i aesni shows nothing?

No nothing (13.1-RELEASE-p3). dmesg | grep -i features shows nothing either which is strange.

grep -i features /var/run/dmesg.boot

Thanks covacat grep -i aes /var/run/dmesg.boot gives : aesni0: <AES-CBC,AES-CCM,AES-GCM,AES-ICM,AES-XTS>. Any idea how to verify that ZFS is using AES-NI, or is that the default on a cpu with AES support?
