The Linux kernel is a free and open-source, monolithic, modular, multitasking, Unix-like operating system kernel.


ethtool ops for netdevsim

a project by mkubecek

This can be seen as a subproject of ethtool netlink interface but from the technical view it's independent. Every new piece of software is going to be buggy and with frequent changes and rewrites, new regressions are introduced. Automated selftests can help a lot but as ethtool deals with hardware devices, we do not want these tests to depend on a specific hardware. The netdevsim driver was created as a virtual device which (unlike e.g. dummy) cannot be used for actual network traffic but implements various configuration interfaces so that it can be used for their (automated) testing.

Investigate C-Sky architecture

an invention by a_faerber

The youngest architecture addition to the mainline Linux kernel was C-Sky (arch/csky/). I have a GX6605S board booting a downstream 4.9 kernel. It uses a proprietary GxLoader bootloader (similarities with U-Boot exist but no sources...) with uImage and gx6605s.dtb files in a FAT partition on USB stick.

Support for DRM platform drivers

an invention by tdz

This project could get us rid of the last fbdev drivers we're stil shipping: efifb and vesafb. Platform drivers handle hardware that is not auto-detected, but somehow there. For graphics this would be VGA, VESA, or UEFI framebuffers. In SUSE Linux, we currently support VESA and UEFI with fbdev drivers. Those load early in the boot process and maintain graphics hardware until the actual driver takes over.

Mainline Sunplus Plus1 SP7021 kernel for Banana Pi F2S

a project by a_faerber

The recent Banana Pi BPI-F2S board features a new Arm SoC SP7021 by Sunplus, which is not yet supported in mainline Linux. Prior to Hackweek I had prepared UART and interrupt controller drivers and Device Tree for Sunplus SP7021's Arm Cortex-A7 cores: GitHub branch f2s-next

DRM driver for USB-based SiS graphics cards

a project by tdz

Back in the late 90s to early 2000s, SiS graphics chips were fairly common and found in many low-end devices. Today, the chips are still capable enough for simple graphics needs, but the graphics cards were on PCI and AGP buses. They are not usable in modern computers. However, there exist USB-based graphics cards with a SiS 315 graphics chip. Those are around on Ebay et al [1] and easily usable with current computers. I already do have a driver for the old PCI-based SiS drivers and have long been struggling to find something useful to do with it. Converting it to serve USB devices would finally make it useful.

Test mainline kernel on an older Qualcomm SOC (msm89xx), explore current Qualcomm mainlining kernel effort

an invention by pvorel

Project Description

Qualcomm concentrate on supporting recent SOC, older ones aren't supported (use very old downstream kernel, e.g. 3.10).

Setup A Linux Cross Referencer for SUSE kernels

a project by tdz

Project Description

There's Elixir for browsing mainline Linux releases. We should set up a similar system for SUSE kernel releases.

early stage kdump support

a project by mbrugger

Project Description

When we experience a early boot crash, we are not able to analyze the kernel dump, as user-space wasn't able to load the crash system. The idea is to make the crash system compiled into the host kernel (think of initramfs) so that we can create a kernel dump really early in the boot process.

generic zswap dedup

a project by ailiopoulos

Project Description

zswap [1] is a linux kernel component that provides in-memory compression for swap pages. It already provides a limited form of deduplication: if a page is filled with the same value (e.g. all-zeroes) then only that value is kept instead of compressing the contents.

Poking technologies for enrolling customer key to kernel trusted keyring

a project by joeyli

Project Description

The keys in db or mok can be used to verify boot loader and kernel binary for booting. But upstream kernel doesn't trust them for enrolling to trusted keyring because they are enrolled outside the boundaries of kernel. Which means that IMA can not use db/mok keys for verification.

Model checking the BPF verifier

a project by shunghsiyu

Project Description

BPF verifier plays a crucial role in securing the system (though less so now that unprivileged BPF is disabled by default in both upstream and SLES), and bugs in the verifier has lead to privilege escalation vulnerabilities in the past (e.g. CVE-2021-3490).

Nanos Unikernel

an idea by rpalethorpe

Project Description

Nanos is a "unikernel" providing a subset of Linux kernel features. It only allows a single process to run, but has multiple threads. It maintains the kernel-land to user-land boundary unlike other unikernels (so perhaps isn't strictly a unikernel).

Explore Steam Deck issues in openSUSE Tumbleweed

a project by tschmitz

Project Description

The Steam Deck is a portable gaming handheld built around platform technology similar to the one found in AMD mobile laptops. Vendor Valve ships a custom Linux distribution with downstream patches on this device, but booting into other distributions is possible. Connecting the Steam Deck to a dock can turn it into a compact workstation.

Understand and review klp-convert patchset

a project by mpdesouza

Project Description

klp-convert is a tool that is trying to be merged into the Linux Kernel to help livepatching non exported functions. Since kallsymsoneachsymbol and kallsymslookup_name were unexported, klp-convert appeared to solve the issue by creating relocation entries for non-export functions in the final livepatch module.

Improve Qualcomm SOC msm8994/msm8992 kernel mainline support

a project by pvorel

Project Description

Due previous hackweek (https://hackweek.opensuse.org/projects/test-mainline-kernel-on-an-older-qualcomm-soc-msm89xx-explore-mainline-kernel-qualcomm-mainlining) both msm8994 angler and msm8992 bullhead are booting and due other activity (including my work) both have working SD card, but that's just start. Add support for other functionality.

Create a DRM driver for VGA video cards

a project by tdz

Yes, those VGA video cards. The goal of this project is to implement a DRM graphics driver for such devices. While actual hardware is hard to obtain or even run today, qemu emulates VGA output. VGA has a number of limitations, which make this project interesting.

drgn: implement crash top-level commands

a project by marxin

Project Description

The goal of the project is to implement a collection of top-level crash commands in drgn tool. The commands should provide a top-level overview for anybody who opens a kernel core dump. I plan to select a similar set of commands as seen in crash-python tool.

How software creation process can save energy and CO2 emissions

an invention by acervesato

Project Description

Everything we do in SUSE requires a certain amount of energy. This energy has a cost and it causes also a certain amount of CO2 emissions. In particular, as Kernel QA team, we run Kernel testing pretty often causing energy consumption that could be saved by introducing optimizations inside the LTP testing.

Linux on Cavium CN23XX cards

a project by tsbogend

Before Cavium switched to ARM64 CPUs they developed quite powerful MIPS based SOCs. The current upstream Linux kernel already supports some Octeon SOCs, but not the latest versions. Goal of this Hack Week project is to use the latest Cavium SDK to update the Linux kernel code to let it running on CN23XX network cards.
