|---|---|---|
| Challenges Around Long-Term Kernel Maintenance | Sasha Levin | 41m |
Maintaining long‑term stable kernels becomes exponentially harder as trees diverge: the project sees about 10,000 commits per release cycle, simple… | ||
| RISC-V-Based Sandboxing for Secure and Efficient Software Execution | Jim Huang, Yen-Fu Chen | 34m |
rv32emu is a compact ~10k‑line RV32 simulator that runs RV32IM ACF binaries, reduces memory footprint, and matches or beats Spike for interpreter-only… | ||
| Compute Express Link(CXL), the Next Generation Interconnect - Overview and the Status of Linux | Yasunori Goto | 39m |
CXL is now at CXL 3.1 with fabric support (port‑based routing, 12‑bit port IDs for ~4,096 nodes) and global integrated memory; Linux has a basic CXL memory… | ||
| From an OSS-Fuzz Report to LKML Patch Submission: A Hands-on Journey | Shung-Hsi Yu | 30m |
Walks from OSS-Fuzz report 40868/40957 to a Linux kernel patch: uses OSS-Fuzz reproducers to reproduce crashes locally, builds with AddressSanitizer… | ||
| Are Our Systems Using up-to-Date Cryptography? | Daiki Ueno | 29m |
A system-wide auditor is built that instruments crypto libraries with USDT and eBPF, attaches an eBPF program to running processes, and exports events via an… | ||
| High Stability Rust in Kernel by Kernel CI | Arisu Tachibana | 34m |
KernelCI runs builds of rust-for-linux using a Docker image with rust toolchain that installs rustc, bindgen and formatting tools; current CI compiles a couple… | ||
| Building Hard Real-Time Linux Systems with Xenomai | Jan Kiszka | 38m |
Claims that Xenomai's co‑kernel still beats PREEMPT_RT for some mission‑critical use cases and that Xenomai 3 vs Xenomai 4 (EVL) tradeoffs matter, with… | ||
| The Future of AlmaLinux: Collaborating on Development and Adoption from Japan | Yohei Suzuki, benny Vasquez | 33m |
AlmaLinux claims near-complete RHEL compatibility by using CentOS Stream as upstream and pulling patches where allowed, with less than 1% of code differs… | ||
