Possible missing firmware /lib/firmware/i915/kbl_dmc_ver1.bin for module i915

Asked by chris pollock

Distributor ID: Ubuntu
Description: Ubuntu 16.04.1 LTS
Release: 16.04
Codename: xenial

I use Webmin to install most of my system updates as opposed to the software updater. During some installs I get these warnings:

W: Possible missing firmware /lib/firmware/i915/kbl_dmc_ver1.bin for module i915
W: Possible missing firmware /lib/firmware/i915/bxt_guc_ver8_7.bin for module i915
W: Possible missing firmware /lib/firmware/i915/skl_guc_ver6_1.bin for module i915

The system works fine however I'm curious. Do I

1) need these firmware modules?
2) if so, where do I find them?

Running

chris@localhost:/lib/firmware/i915$ sudo apt install kbl_dmc_ver1
[sudo] password for chris:
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package kbl_dmc_ver1

or

chris@localhost:~$ sudo apt install kbl_dmc_ver1.bin
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package kbl_dmc_ver1.bin
E: Couldn't find any package by glob 'kbl_dmc_ver1.bin'
E: Couldn't find any package by regex 'kbl_dmc_ver1.bin'

doesn't find the package.

If these aren't necessary I'm not going to worry about it.

kbl_dmc_ver1.bin and skl_guc_ver6_1.bin are in the linux-firmware package from Yakkety

Its not in the Xenial one.

You could install the deb for it, alternatively (cleaner) manually download the firmware files from the web and put them in the /lib/firmware/i915 folder. You may need to make it first by running:

sudo mkdir -p /lib/firmware/i915/

Webmin doesn't teach you transferable skills and having a web interface to control key system components is hardly graceful.

If you want to run updates, install openssh-server then use your remote PC to connect (use PuTTY in Windows if that is the client PC)

You can then run:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt-get clean

You don't need something as huge as Webmin just to do updates. Its ridiculous

Thanks, since it's just a warning I'll have to assume the files aren't really necessary.
