Description Mark Salter 2022-07-21 12:17:16 UTC

Description of problem:
The nvmem-imx-ocotp driver is needed to enable certain hardware on NXP i.MX SoCs which are of interest to potential RHEL for Edge customers. This driver is needed to enable networking among other things. It is included in the initrd created during a kernel install on the target hardware, but it is not included in the PXE kernel initrd which prevents PXE installs from working.

This is gating adding NXP i.MX 8M Quad systems to beaker. We have multiple NXP i.MX 8M Quad systems waiting to be added once PXE booting is working and this fix will allow these systems to PXE boot.

Thanks,

Comment 2 Lukáš Nykrýn 2022-07-26 09:23:30 UTC

In this case, it seems that it should be enough to only include the module in our installation images. I am not sure what service is currently building those images these days. Maybe still lorax? But IMHO, we should reassign the bug there.

Comment 3 Brian Lane 2022-07-26 22:30:48 UTC

It is dracut's responsibility to include drivers in the initrd when lorax runs it in hostonly mode. lorax may trim down the list of existing drivers, but that's not what is happening here since runtime-cleanup.tmpl doesn't remove anything under .../drivers/nvmem/

Comment 4 Steve Best 2022-07-29 14:38:35 UTC

Lukáš,

so is dracut the right component to fix this?

Thanks,
-Steve

Comment 5 Jan Stodola 2022-08-04 16:41:30 UTC

Mark, could you please check what rpm provides the nvmem_imx_ocotp kernel module? I was not able to find such a kernel module.

Comment 6 Mark Salter 2022-08-04 17:21:51 UTC

It's in kernel-core
Sorry, description is wrong. Should be nvmem-imx-ocotp
