Module cryptodev not found

[jcconnell]

I am trying to enable hardware cryptography on my Go Flex Home by following the guide in the community guides section.

I am receiving the following error:
$this->bbcode_second_pass_code('', 'modprobe: FATAL: Module cryptodev not found in directory /lib/modules/4.4.97-1-ARCH')

Has anyone experienced this? Any idea how to resolve it? This is on a fresh installation of Arch.

install cryptodev-dkms

Edit: Sorry, I meant to say that I am still receiving the same message.

$this->bbcode_second_pass_code('', 'modprobe: FATAL: Module cryptodev not found in directory /lib/modules/4.4.97-1-ARCH')

Did you get any errors installing cryptodev-dkms?

[jcconnell]

Yes, I didn't notice previously.

$this->bbcode_second_pass_code('', '

I removed linux-kirkwood-dt-headers and installed linux-kirkwood-headers and then tried installing cryptodev-dkms. This time I received a few new errors.

$this->bbcode_second_pass_code('', '

Finally, here is the make log:

why did you remove the device tree version and used no dt version?

[jcconnell]

I was looking for examples of how other people had accomplished this goal on their Kirkwood devices and saw examples of it being done both ways, dt vs non-dt. I decided to try it as a test.

[Kabbone]

if I remember correctly, it was told one time, that support for non dt-kernel should end at some time, don't know if it already happened as of I ran it with dt

[moonman]

There are 2 problems with linux-kirkwood:
I couldn't get it to compile with gcc8.1, but I haven't looked into it yet. But the error is similar as your are getting trying to compile this module

The current package that's in the repo is compiled with an older version of gcc so there may an incompatibility there.

Yes, non-dt version will be discontinued eventually so if your hardware is supported in linux-kirkwood-dt there is no reason why you should be running non-dt version.
