69. Leveraging Rust's Field Projections in the Kernel and Beyond

Benno Lossin

Several Rust contributors and I have been collaborating on a novel language feature called "Field Projections". The feature is still being designed and implemented, so now is a good opportunity to experiment with it to see what new APIs it unlocks for the Kernel and other projects. We also want to investigate any gaps in our current design that prevent important use-cases from being...

189. Challenges in multi-tenant GPU sharing

Boqun Feng, Gregoire Pean, Jatin Kataria

We would like to share some of the challenges we have encountered in a multi-tenant GPU environment, discuss the solutions we have explored, and gather feedback from the community.

To provide context for the audience, we will start by giving an overview of our multi-tenant architecture. We then plan to discuss several areas where we have encountered challenges, including:

• GPU reset...

63. DRM: handling runtime requirements for device components.

Mr Dmitry Baryshkov (Qualcomm)

The DRM susbsytem grew up from the desktop GPUs, where the device is a single unit, powered on and off only at the important runtime points. For the embedded display controllers it's no longer true. The display pipeline can consist of several different devices, each having its own runtime power up and down code points. Handling device power on and off in the existing atomic callbacks makes the...

153. Kernel CVEs at AWS Scale: Two Years of Empirical Findings

Mr Dylan Johnson (Amazon Web Services), Mr Justinien Bouron (Amazon Web Services)

Since the Linux kernel project became a CVE Numbering Authority (CNA) in February 2024, organizations maintaining custom kernels have faced a flood of CVE disclosures.

We present empirical findings, lessons learned, and the key challenges that the kernel team responsible for Amazon Web Services fleet infrastructure encountered over the following two years while handling the steady flow of...

138. Regressions & tracking them: current state, plans, and what do you want?

Thorsten Leemhuis

Provide a quick "state of the union" about the Linux kernel regression ecosystem in the first part of the session before spending the second discussing what improvement the members of the audience wish for in this area.

The first part is meant to take less then half of the allotted time and will cover things like:

• KernelCI and regzbot joined forces -- what this means for the future.
  *...

25. Rust for Linux

Miguel Ojeda

Rust for Linux is the project adding support for the Rust language to the Linux kernel. This talk will give a high-level overview of the status and the latest news around Rust in the kernel since LPC 2025.

17. Maintainer-oriented features of b4

Konstantin Ryabitsev (The Linux Foundation)

B4 is already a well-known tool for retrieving and applying series from lore.kernel.org. Recently, it gained several new features that can make the life of a maintainer a bit easier:

• b4 review - helps with code review and full series lifecycle management
• b4 bugs - integrates distributed bug tracking into your workflow

This session will go over the new features and how they can...

66. Bringing Linux DRM Display Panel support in the modern age

Neil Armstrong (Linaro)

Since the introduction of the first Samsung DSI panel, the Linux DRM panel API has been a crucial piece of software for enabling displays across diverse architectures, but it has not evolved alongside modern graphics stacks. Currently, the API lacks atomic DRM API support and the ability to adapt power setups during mode changes. Furthermore, it fails to support advanced Display Driver IC...
