Renegade hardware AES support not activated under Armbian?

[switch]

The Libre Computer Renegade RK3328 has hardware AES support. Should it not be listed by `lsmod` if the module is activated?

 

$ grep aes /proc/cpuinfo
Features    : fp asimd evtstrm aes pmull sha1 sha2 crc32 cpuid
Features    : fp asimd evtstrm aes pmull sha1 sha2 crc32 cpuid
Features    : fp asimd evtstrm aes pmull sha1 sha2 crc32 cpuid
Features    : fp asimd evtstrm aes pmull sha1 sha2 crc32 cpuid


$ lsmod | grep aes
$

 

How can one verify that the AES chip is being utilized?

 

I'm on the Armbian 22.11 Jammy release (Kernel 5.15.y, Release date: Nov 30, 2022).

Hello switch,

 

   While the RK3328 does have the hardware, the crypto patches have not made it into the mainline kernel yet:  https://patchwork.kernel.org/project/linux-rockchip/list/?series=680902

 

As a result the hardware crypto won't be available.  That patchset infers it is identical to the crypto module in the RK3288, so as long as the RK3399 parts of that deries don't tie it up, it should be applied soon.

Hi @TonyMac32,

 

Thanks for that information. Looking forward to the kernel update.

I have a similar question regarding the BPI-M2S (A311D): https://patchwork.kernel.org/project/linux-amlogic/list/

 

Is that single crypto entry what's preventing enabling AES support in the kernel?
