lineageos_kernel_builder

Bash script to build a custom LineageOS Kernel without having to download unnecessary source code.

Supported devices

• Sony Xperia 1 II (pdx203)
• Sony Xperia 5 II (pdx206) (not regularly tested, should work)
• OnePlus 6 (enchilada) (untested)
• OnePlus 6T (fajita) (untested)
• Xiaomi Mi Mix 2S (polaris) (not regularly tested, should work)

How to use

• Check ./config.sh for configuration options.

• Symlink a device configuration file from ./device_configs/ to ./include/device_config.sh before running lineageos_kernel_builder.sh, for example:

ln -sf ./device_configs/pdx206_device_config.sh ./include/device_config.sh # We are now building for pdx206

• Then:

lineageos_kernel_builder.sh download_sources
# lineageos_kernel_builder.sh make_defconfig  # optional: run "make defconfig" in Kernel source directory
# lineageos_kernel_builder.sh make_menuconfig # optional: run "make menuconfig" in Kernel source directory
lineageos_kernel_builder.sh make_kernel
lineageos_kernel_builder.sh make_anykernel3_zip # ${enable_anykernel3_zip} needs to be "true" for this to work

• You can also run build_all_configs.sh to build for all device configs in ./device_configs/.

(Recommended) Using cached prebuilts_clang_host_linux_x86

• Because prebuilts_clang_host_linux_x86 is very big (about 13GB!), you can cache it to avoid redownloading everytime you build the Kernel:

lineageos_kernel_builder.sh download_sources
mkdir -p ./cache/
source ./include/device_config.sh
cp -r ./build/prebuilts/clang/host/linux-x86 ./cache/prebuilts_clang_host_linux_x86-${aosp_tag}

• Now everytime you build the script will use the cached prebuilts_clang_host_linux_x86 instead.

Differences compared to building with the whole LineageOS ROM

• none (as far as I know)
