I'm a Linux Kernel / BSP / Android System Engineer focusing on
low-level system software, driver development, and embedded Linux platforms.

I enjoy understanding how systems actually work —
from bootloader to kernel, from hardware signals to userspace behavior.

• 🐧 Linux Kernel

  • Kernel internals & runtime behavior
  • Driver model & subsystem interaction
  • Synchronization, scheduling, memory, cgroups
  • Upstream-oriented development and patch workflow

• 📦 BSP & Embedded Linux

  • Boot flow (ROM → U-Boot → Kernel → Userspace)
  • Device Tree, pinmux, clock, power domains
  • SPI / I2C / PCIe / MIPI interfaces
  • Yocto-based BSP design and customization

• 🤖 Android System

  • Android process & runtime model
  • Kernel–userspace integration
  • Android kernel configuration & debugging
  • Wi-Fi / display / power bring-up issues

I maintain a long-term technical knowledge base where I document:

• Kernel internals & subsystem deep dives
• Real debugging cases and post-mortems
• BSP and Android integration notes
• Minimal code examples for core concepts

• Linux kernel debugging: ftrace, perf, KGDB, addr2line
• Build systems: Yocto, Buildroot
• Debug & bring-up: GDB, serial console
• Platforms: NXP / Renesas / Rockchip SoCs

• Deeper DRM & display subsystem internals
• Advanced kernel tracing and performance analysis
• Cleaner upstream-ready driver design

• GitHub: you're already here 🙂
• Open to technical discussions and knowledge sharing
