| # ============= |

| # |
| # TARGET_KERNEL_SOURCE = Kernel source dir, optional, defaults |
| # to kernel/$(TARGET_DEVICE_DIR) |
| # TARGET_KERNEL_CONFIG = Kernel defconfig |
| # TARGET_KERNEL_VARIANT_CONFIG = Variant defconfig, optional |
| # TARGET_KERNEL_SELINUX_CONFIG = SELinux defconfig, optional |
| # TARGET_KERNEL_ADDITIONAL_CONFIG = Additional defconfig, optional |
| # TARGET_KERNEL_ARCH = Kernel Arch |
| # TARGET_KERNEL_HEADER_ARCH = Optional Arch for kernel headers if |
| # different from TARGET_KERNEL_ARCH |
| # TARGET_USES_UNCOMPRESSED_KERNEL = 'true' if Kernel is uncompressed, |
| # optional, defaults to false |
| # TARGET_KERNEL_CROSS_COMPILE_PREFIX = Compiler prefix (e.g. arm-eabi-) |
| # defaults to arm-linux-androidkernel- for arm |
| # aarch64-linux-androidkernel- for arm64 |
| # x86_64-linux-androidkernel- for x86 |
| # |
| # BOARD_KERNEL_IMAGE_NAME = Built image name, optional, |
| # defaults to Image.gz on arm64 |
| # defaults to Image if TARGET_USES_UNCOMPRESSED_KERNEL |
| # defaults to zImage otherwise |
| # |
| # KERNEL_TOOLCHAIN_PREFIX = Overrides TARGET_KERNEL_CROSS_COMPILE_PREFIX, |
| # Set this var in shell to override |
| # toolchain specified in BoardConfig.mk |
| # KERNEL_TOOLCHAIN = Path to toolchain, if unset, assumes |
| # TARGET_KERNEL_CROSS_COMPILE_PREFIX |
| # is in PATH |
| # USE_CCACHE = Enable ccache (global Android flag) |
| # |
| # NEED_KERNEL_MODULE_ROOT = Optional, if true, install kernel |
| # modules in root instead of system |
| |
