Aosp Kernel And Boot

AOSP Part II — Kernel & Boot. Use when reasoning about Android's bootloader handoff, init.rc / first-stage init / second-stage init, the Generic Kernel Image (GKI) and KMI stability, dm-verity / Android Verified Boot, the kernel's Android-specific subsystems (binder driver, ashmem→memfd, low-memory killer, PSI), vendor modules, or system properties (property_service, property contexts, ro/persist/sys/build prefixes). Chapters 4–6.

AOSP Part II — Kernel & Boot

How an Android device boots, how the Generic Kernel Image keeps vendor and platform decoupled, and how system properties fan out across the early-boot trust chain.

  • 05-kernel.md — Generic Kernel Image, vendor modules, KMI stability, dm-verity / AVB, Android-specific subsystems
