| Tutorial: Zoom on Cilium: An Interactive Tutorial to Learn How to Reshape the Traffic... | Adam Sayah | 01h 13m |
Hands-on demo of eBPF + XDP that builds and runs real kernel programs: compiles C eBPF code, attaches it to eth0, and shows three concrete effects — drop IPv6… | ||
| TCP Socket Lookup Degradation and per-Netns Ehash | Kuniyuki Iwashima | 26m |
Kernel TCP lookup uses three global hash tables B/L/E and long lists slow lookups so a single noisy tenant can cut TCP throughput. Experiments show throughput… | ||
| QEMU: Emulating Your Way to Success | Ben Dooks | 41m |
Codethink uses QEMU to run system-level emulation for CI and development, integrating with openQA and LAVA to boot full images and catch roughly 80% of… | ||
| Current Status and Future of HWPOISON Subsystem | Naoya Horiguchi | 40m |
Explains concrete kernel work: error handling now keeps poisoned pages in pagecache (so data loss on writeback is reduced), accounting changes land since 5.18… | ||
| Delivering Security Fixes Continuously Into Your Embedded Linux | Hiraku Toyooka | 34m |
Yocto-based EM Linux pulls full upstream SLTS kernels from CIP (10+ year support) and Debian packages via meta-debian to deliver monthly updates and a 10-year… | ||
| Use Dmabuf to Streamline Sensor Data Handling | Wendy Liang | 38m |
Shows a working zero‑copy sensor pipeline built with Linux kernel primitives: buffers allocated from preferred memory via dma_heap and reserved memory, shared… | ||
| Hyperscale Kernel Live Patching at Meta | David Carl Vernet, Song Liu | 28m |
Meta deploys kernel live patching as RPMs with automated health checks and cumulative patch atomic swaps using the replace flag. Applying a KLP takes 1–2… | ||
| Generic ALSA SoC Sound Card History (Simple/Graph) | Kuninori Morimoto | 31m |
Timeline of how ALSA SoC moves from per-board card drivers to three generic drivers, showing a concrete migration path that touches simple-card… | ||
| Function Dedicated Network Deployment Model in DPU/IPU-Like Device Acro... | Hidetsugu (Hyde) Sugiyama | 39m |
Claims that DPU/IPU cards plus an all‑photonic backbone can cut CPU use and reach sub‑10 ms XR motion‑to‑photon and net‑zero energy targets by 2030, using GPU… | ||
| How to Investigate Issues on Linux Embedded System? | Yoshihiro Shimoda | 39m |
Shows concrete debugging steps for R-Car Linux boards: uses ftrace and memtest to capture traces and rare memory corruption, enables early-console and KDB for… | ||
| Time-Sensitive Networking (TSN) with Mainline Embedded Linux | Marcel Ziswiler | 40m |
Shows how mainline Linux implements TSN end-to-end: use the TC subsystem and tc utility to configure Credit-Based Shaper (CBS), queueing via ETF / TXTIME and… | ||
