Printk Should Be Your Last Resort - Sundeep Subbaraya, Marvell

Tuesday August 5, 2025 11:35am - 12:00pm IST

Hall 1

This session will provide a walkthrough of Linux kernel tracing capabilities, demonstrating live debugging techniques for Linux drivers using a dummy netdev driver. We will explore various kernel debugging facilities and how to infer real-time insights without relying on printk debugging.

Speakers

Linux's Leap Beyond Fixed Pages - Dev Jain, Arm

Tuesday August 5, 2025 12:15pm - 12:40pm IST

Hall 1

A longstanding challenge in Linux has been the inefficiency of the 4KB base page size—while it reduces internal fragmentation, it causes longer LRU lists, more page faults, and more TLB misses. Transparent Huge Pages (THP) mitigate this by dynamically allocating larger pages (2MB).

Speakers

Dev Jain

Graduate Software Engineer, Arm

Dev is a software engineer at Arm India. He does Linux kernel development as part of the kernel Memory Management Performance team at Arm. Besides the kernel, he is interested in algorithms and mathematics.

Future-Proof Your Applications: Avoid Breakdowns With Cgroup Changes! - Kamalesh Babulal & Tom Hromatka, Oracle Corporation

Tuesday August 5, 2025 1:40pm - 2:05pm IST

Hall 1

cgroup v2 is now the default resource management system in modern Linux kernels, container runtimes, and orchestration platforms. Migrating from cgroup v1 to cgroup v2 is essential for improving resource management but migrating from v1 risks potential outages, performance regressions, and hidden legacy dependencies. In this session, we'll provide a concise introduction to cgroups, showing how cgroup v1 evolved into cgroup v2.

Kernel TEE Subsystem Evolution - Sumit Garg, Qualcomm Inc.

Tuesday August 5, 2025 2:15pm - 2:40pm IST

Hall 1

A Trusted Execution Environment (TEE) is an isolated execution environment running alongside the rich operating system. It provides the capability to isolate security-critical or trusted code and corresponding resources like memory, devices, etc. The isolation is backed by hardware security features such as Arm TrustZone, AMD Secure Processor, RISC-V TEE, etc.

Auto-instrumenting Native (C++ and Rust) Applications Using eBPF and OpenTelemetry - Lalit Kumar Bhasin, Microsoft

Tuesday August 5, 2025 2:50pm - 3:15pm IST

Hall 1

Auto-instrumentation for native applications—especially in C++ and Rust—is one of the toughest challenges in observability. Unlike managed languages like Java that provide runtimes with built-in instrumentation hooks, or languages like Go that offer limited runtime metadata, native applications expose no dynamic introspection or tracing facilities. This makes traditional approaches ineffective or invasive.

Speakers

Lalit Kumar Bhasin

Principal Engineer, Microsoft

Lalit Kumar Bhasin is a maintainer of OpenTelemetry C++ and OpenTelemetry Rust, with a strong focus on observability in native and systems-level environments. He has spent the past five years at Microsoft working on production-grade telemetry pipelines and open-source instrumentation... Read More →
