UCSI, TCPM, PD, AltModes: Demystifying USB-C and Its Support in Linux - Dmitry Baryshkov, Linaro Ltd.

Wednesday September 18, 2024 11:00 - 11:40 CEST

Hall B (Level 2)

Implementing Type-C support in Linux is not a simple task, platforms implementers have to understand different pieces of the Type-C stack (and various USB standards). This talk provides overview of the Linux USB-C subsystem and its different parts, basing on my experience with implementing and improving USB-C support for different Qualcomm platforms.

VirtIo-Net PCIe Function Using Linux PCI Endpoint Framework - Shunsuke Mie, IGEL Co., Ltd.

Wednesday September 18, 2024 11:55 - 12:35 CEST

Hall B (Level 2)

The PCI Endpoint framework enables the Linux kernel to act as a PCI Endpoint device. It allows software to describe the behavior of a PCIe function, which is a logical unit within a PCI device. This session will present the design and implementation of a virtio-net device using this framework.　Virtio is a para-virtualization framework designed to improve the efficiency of device I/O operations in virtualized environments. It enables software to emulate device behavior, leading to efficient data transfers in this case.　This session will discuss the architecture and current status of the proposed virtio-net PCI function driver based on the PCI endpoint framework. Additionally, it will introduce an API for controlling virtio virtqueues, which are used for data transfer. This API is generic and can be used to implement PCI Endpoint devices for other virtio devices.

OpenPrinting - We Make Printing Just Work! - Till Kamppeter, OpenPrinting / Canonical

Wednesday September 18, 2024 15:10 - 15:50 CEST

Hall B (Level 2)

Conference attendees to Till: Printing works better than under Windows or Mac! Michael Tunnell, TuxDigital, says in one of his videos: There is no such thing like a pain-free experience of printing under Windows ... Linux printing is ridiculously good ... Till Kamppeter, leader of the OpenPrinting project, and fellow of the Linux Foundation, will give an overview of his work. Going through OpenPrinting's history the components of the printing infrastructure of modern Linux (and other Posix-style) operating systems will get shown. - How did the Internet Printing Protocol (IPP) with the printing system CUPS being an implementation of it simplify printing a lot? - The printer driver challenge, good and bad cooperation with manufacturers, packaging and distributing ... - Desktop integration, GUI toolkits, print dialogs, setup tools, portals, ... Especially also the New Architecture of all-IPP printing and scanning and also the integration in immutable OS distributions will be treated ...

What Is an ABI, and Why Should You Care? - Shung-Hsi Yu, SUSE

Wednesday September 18, 2024 16:05 - 16:45 CEST

Hall B (Level 2)

Application Binary Interface (ABI), in contrast to the more often heard Application Programming Interface (API), is not as widely discussed, but is every bit as important as the latter. It is what allows us to run programs that are compiled 10 years ago on the latest system, and still expect it to work. In this talk, we will introduce the audience to the concept of ABI, explain its difference from API, and and lay out what exactly breaks ABI, as well as cover the symptoms of such breakage. Further more, we will detail how ABI breakage can be detected or prevented, and discuss some specific cases: Linux Kernel's ABI, Python's stable ABI, and Foreign Function Interface.

Speakers

Shung-Hsi Yu

Kernel Engineer, SUSE

Mainly working on maintaining the eBPF stack of SUSE Linux Enterprise Server (SLES) distribution. Currently drawn to the inner working of eBPF verifier and formal verification.
