[i.Mx8QX] DM-Crypt: dmsetup not found

[syuanyang]

Hi,
I'm trying to follow the doc to enable DM-Crypt with CAAM.
https://www.nxp.com/docs/en/application-note/AN12714.pdf

But I cannot find dmsetup tool.
root@imx8dxptbox:/# dmsetup targets
-sh: dmsetup: command not found

Anything I missed?

Here are my device info:
I can found device-mapper was launched. Related log showing from dmesg

[ 3.358614] device-mapper: uevent: version 1.0.3
[ 3.363547] device-mapper: ioctl: 4.37.0-ioctl (2017-09-20) initialised: dm-devel@redhat.com
[ 3.372145] device-mapper: multipath round-robin: version 1.2.0 loaded

My CAAM related kernel config setting:

Hi Yuri,

May I know the keyutils package is packed into NXP's kernel release by default?

When I run the build, the keyutils package cannot be found.

Hello,

  According to section 3.1 (Installation) of the app note recent release (Rev. 2, 02/2021),
Lvm2 provides dmsetup utility and libraries to manage device-mapper.

  Also:
If not already installed, add the required tools to build by editing the conf/local.conf file and appending.

CORE_IMAGE_EXTRA_INSTALL+="coreutils keyutils lvm2 e2fsprogs-mke2fs util-linux"
