Is it possible to add modules to qlustar linux kernel?
Hi all, I'm trying to set up Qlustar 12.0 with ubuntu focal on a HP machine equiped with a smart array controller P816i-a. The problem is that the smart array is not recognized after install: I can see it with lspci, but the disks are not listed in /dev. As far as I understand, this is a driver issue : the smartpqi module is required for this smart array. This module is available from "linux-modules-extra" in ubuntu focal 20.04, but this package is not part of the qlustar distribution. So questions : 1 - Is there a way I can simply add a required module (for example .ko file) in the qlustar kernel and simply recompile the qlustar kernel? 2 - failing that, should I expect trouble running qlustar with a "pure ubuntu" kernel ? If I add the focal repository in apt sources and install linux-modules-extra, I can build a new kernel OK, but it is "pure ubuntu" - not qlustar. Is qlustar kernel just a light version of the ubuntu kernel and that's ok? or does qlustar include extra components ? Any input appreciated PYB

You can always install the package linux-headers-<version info>_amd64.deb and compile your add-on modules against the kernel headers contained in it. $ apt-cache search 'linux-headers.*ql-generic' lists the available versions and you will have to choose the one matching the kernel version you are running.

But as soon as you need support for special things like Infiniband, Lustre, Nvidia GPUs, things will get complicated and possibly will break. Best, Roland PY> Any input appreciated PY> PYB
