Surface Laptop Studio kernel

This fork builds Linux 7.2.0 for my first-generation Microsoft Surface Laptop Studio running Fedora 42. It is not a general linux-surface package repository.

The build applies the Surface patch series and the CachyOS BORE scheduler to Fedora's kernel-7.2.0-2 kernel-ark tag. The machine config enables CachyOS-style pre-emption, timer, CPU, memory, storage, networking and compression settings. It produces RPMs named kernel-surface.

CPU vulnerability and bus-lock mitigations remain enabled. Secure Boot support is absent because this machine has Secure Boot disabled.

Build

Install Fedora's kernel build dependencies once:

sudo dnf install @rpm-development-tools git
sudo dnf builddep kernel

Build the binary RPMs from the repository root:

python3 pkg/fedora/kernel-surface/build-linux-surface.py

The script uses kernel-ark/ as a disposable source tree and deletes all uncommitted files inside it on every run. RPMs are copied to out/.

To build only the source RPM:

python3 pkg/fedora/kernel-surface/build-linux-surface.py --mode srpm

Install and rollback

Install the generated packages with DNF so the transaction remains in RPM history:

sudo dnf install out/*.rpm

Reboot into the new kernel-surface entry, then check the running release:

uname -r

Keep the current Fedora kernel installed. If the custom kernel fails, select the Fedora kernel from GRUB and remove the custom packages with the matching DNF history transaction.

Source layout

• patches/7.2/ contains the linux-surface patch series ported to Linux 7.2.
• patches/cachyos-7.2/ contains the CachyOS BORE scheduler port for Fedora kernel-ark.
• configs/surface-laptop-studio.config contains the overrides for this machine.
• pkg/fedora/kernel-surface/ contains the Fedora RPM build scripts and packaging patches.

Kernel-derived patches retain their original licences. See each patch for its licence and authorship.
