Building ISO with latest kernel

User Support
1

Hi,

I am running 4.1 on a brand new laptop - and it works really fine, including some bugs :-). I tried to install 4.0.4 first but this one did not work due to cpu panic and some IO-APCI bug. So I was wondering if is possible to build an iso with the latest kernel version to solve this IO-APCI problem.

Best regards

Hi @qubesfan35267,

the related documentations are :

Another way is to try to modify the 4.0.4 ISO by changing only the kernel.

But note that I never did these two ways…

Hi,
thank you for the answer. Building the iso is not the problem…I am lacking the knowledge to integrate the latest kernel into the process.

Best regards

@qubesfan35267 for development-related questions the mailinglist qubes-devel may be better suited as that’s where most developers are.

I’ve just compiled working linux-kernel-5.12.8 for dom0.

QubesOS
QubesOS1916×500 67 KB

I am working on QubesOS 4.1. Here is what I’ve done:

In dom0, Create Qubes VM
name: build_qubes_kernel
Type:AppVM
Template: fedora-32 (same as dom0)
(I have not changed max RAM/VCPUs)
start terminal in new AppVM

git clone https://github.com/QubesOS/qubes-builder.git
Verify repository follow docs
cd qubes-builder
cp example-configs/kernel.conf builder.conf
(please read builder.conf contents)
edit builder.conf - change “RELEASE := 4.0” to “RELEASE := 4.1”
edit example-configs/qubes-os-r4.1.conf - change “GIT_PREFIX ?= QubesOS/qubes-” to “GIT_PREFIX ?= marmarek/qubes-”

make remount
make get-sources
make install-deps
If you want to change kernel version default now is 5.12.5(I changed it to 5.12.8):
1)edit qubes-src/linux-kernel/version
2)make get-sources

make qubes

Building kernel took about 2 hours.
In dom0:

mkdir ~/kernel
cd ~/kernel
check rpm packages names:
qvm-run --pass-io build_qubes_kernel ‘ls /home/user/qubes-builder/qubes-src/linux-kernel/pkgs/dom0-fc32/x86_64’
copy packages to dom0 for each package (there are three of them) run:
qvm-run --pass-io build_qubes_kernel ‘cat /home/user/qubes-builder/qubes-src/linux-kernel/pkgs/dom0-fc32/x86_64/[package name here]’ > [package name here]

sudo qubes-dom0-update elfutils-libelf-devel

for each package (there are three of them)
sudo dnf install -y ./

Changing to marmarek/qubes- is useless. Especially, you get out what’s built into Qubes or what’s updated on the git repository.
