Introduction

Born in August 2000, Korea.
I love the Linux kernel and FOSS.

Recently graduated from Chungnam National University (Feb. 2025).

Currently I am:

• A Linux Kernel Developer (MM) @ Oracle
• An Official Reviewer for Linux Kernel Slab & Reverse Mapping Subsystems

My contributions to the Linux kernel

As Harry Yoo
As Hyeonggon Yoo (before joining Oracle)

As you can see, I spend most of my time reviewing patches but I'm also working on cool projects!

A few internships I've done before graduating university

• Software Engineering Intern @ SK Hynix (Dec. 2024 ~ Jan. 2025)
  • Worked on software solutions for CXL-based heterogeneous memory systems.
• Security SW Engineering Intern @ NVIDIA (Jun. 2024 ~ Nov. 2024)
  • Worked on enabling OP-TEE on new NVIDIA products.
  • Investigated issues with Rust integration on existing C++ projects for Secure Element.
• Software Engineering Intern @ Panmnesia (Sep. 2023 ~ Dec. 2023)
  • Analyzed CXL 2.0 device emulation.
  • upstreamed several fixes to QEMU CXL emulation.

Topics that I'm interested in:

• Linux
  • BPF/Perf (System Performance Analysis)
  • Memory Management Subsystem
  • Linux's Slab allocator (aka. SLUB)
• Computer Architecture
• Virtualization
• Algorithm
