Pixel 8 Series Kernel Builder

My personal build system for custom Android 16 kernels.

---

What's Here

Automated GitHub Actions workflow that builds GKI kernels with three KernelSU variants:

• tiann (official)
• kowsu (fork)
• mksu (fork)

Quick Run

Takes about 14-15 minutes total for all three variants.

• Android 16
• Kernel 6.1.157
• KernelSU integrated
• Optional SuSFS for root hiding

Current Status

Version: v4.1

Optimizations:

• Parallel downloads
• Smart CPU/RAM detection
• 92%+ cache hit rate
