I have a small NAS home server with debian10 and openmediavault on it, and the data partitions of all 4 Harddisks encrypted with LUKS. Since the old atom Processor on the Motherboard was the bottleneck in all I/O operations, i recently bought a cheap Mini-ITX board (ASRock E-350-M1) with an soldered-on AMD E-350.
I have chosen the board because
https://www.cpu-monkey.com/en/cpu-amd_e_350-204 as well as
https://www.technikaffe.de/cpu_vergl...amd_e_350-204/ both claim that this processor has AES-NI support , the respective CPU- enhancements to speed up crypto operations.
But when I issue lscpu, the feature seems not to be there:

Has this feature maybe been renamed on AMD CPUs?
Does this CPU even have crypto support?
If so, how do I enable it in LUKS?
Since I am setting up crypto(and all disks)from scratch anyway, maybe changing the creation process of the LUKS containers could be helpful in speeding up transfers?
