Setup & Sync

1. Initialize Manifest

# Create working directory
mkdir ~/realme12pp-kernel && cd ~/realme12pp-kernel

# Initialize repo with the remote manifest
repo init -u https://github.com/RemuruSama/coffee-kernel_manifest.git -b master -m realme_12proplus_b.xml

2. Sync Sources

# Full sync
repo sync -j8 --no-tags --no-clone-bundle

# Or sync step by step (recommended for first time)
repo sync kernel_platform/common -j4 --no-tags
repo sync kernel_platform/msm-kernel -j4 --no-tags
repo sync ./ -j4 --no-tags

Build

Build Command

./kernel_platform/oplus/build/oplus_build_kernel.sh parrot gki

What This Does

Argument	Value	Meaning
Platform	parrot	Targets SM7435-AB / Snapdragon 7s Gen 2 SoC
Variant	gki	Builds Generic Kernel Image (GKI 2.0)

Build Variants

# GKI build (recommended)
./kernel_platform/oplus/build/oplus_build_kernel.sh parrot gki

# Consolidate build (includes all drivers/modules)
./kernel_platform/oplus/build/oplus_build_kernel.sh parrot consolidate

Optional Build Flags

# Skip LTO for faster debug builds
LTO=none ./kernel_platform/oplus/build/oplus_build_kernel.sh parrot gki

# Enable aging/debug mode (disables KMI strict mode)
AGING_DEBUG_MASK=1 ./kernel_platform/oplus/build/oplus_build_kernel.sh parrot gki

# Specify number of build jobs
PARALLELISM=16 ./kernel_platform/oplus/build/oplus_build_kernel.sh parrot gki

Notes

• GKI variant is recommended for shipping builds. Use consolidate for development/debugging.
