Hi, all
I am trying to build an Android kernel (branch
android-msm-wahoo-4.4-pie-qpr2) with kasan&kcov enabled using android-llvm
toolchain. I modified build.config to:
ARCH=arm64
BRANCH=android-msm-wahoo-4.4
CC=clang
CLANG_TRIPLE=aarch64-linux-gnu-
CROSS_COMPILE=aarch64-linux-android-
CROSS_COMPILE_ARM32=arm-linux-androideabi-
DEFCONFIG=wahoo_defconfig
EXTRA_CMDS=''
KERNEL_DIR=private/msm-google
POST_DEFCONFIG_CMDS="check_defconfig && update_kasan_config"
function update_kasan_config() {
${KERNEL_DIR}/scripts/config --file ${OUT_DIR}/.config \
-e CONFIG_KASAN \
-e CONFIG_KASAN_INLINE \
-e CONFIG_TEST_KASAN \
-e CONFIG_KCOV \
-e CONFIG_SLUB \
-e CONFIG_SLUB_DEBUG \
-e CONFIG_SLUB_DEBUG_ON \
-d CONFIG_SLUB_DEBUG_PANIC_ON \
-d CONFIG_KASAN_OUTLINE \
-d CONFIG_KERNEL_LZ4 \
-d CONFIG_RANDOMIZE_BASE
(cd ${OUT_DIR} && \
make O=${OUT_DIR} $archsubarch CROSS_COMPILE=${CROSS_COMPILE}
olddefconfig)
}
CLANG_PREBUILT_BIN=prebuilts-master/clang/host/linux-x86/clang-4691093/bin/
LINUX_GCC_CROSS_COMPILE_PREBUILTS_BIN=prebuilts/gcc/linux-x86/aarch64/aarch64-linux-android-4.9/bin
LINUX_GCC_CROSS_COMPILE_ARM32_PREBUILTS_BIN=prebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.9/bin
LZ4_PREBUILTS_BIN=prebuilts-master/misc/linux-x86/lz4
DTC_PREBUILTS_BIN=prebuilts-master/misc/linux-x86/dtc
LIBUFDT_PREBUILTS_BIN=prebuilts-master/misc/linux-x86/libufdt
FILES="
arch/arm64/boot/dtbo.img
arch/arm64/boot/Image.lz4-dtb
vmlinux
System.map
"
IN_KERNEL_MODULES=1
STOP_SHIP_TRACEPRINTK=1
UNSTRIPPED_MODULES="
wlan.ko
"
However, when I tried to build the kernel using build/build.sh, I got
several errors as follows:
aosp-kernel/private/msm-google/drivers/misc/qcom/qdsp6v2/audio_hwacc_effects.c:538:13:
error:
stack frame size of 2144 bytes in function
'audio_effects_compat_ioctl'
[-Werror,-Wframe-larger-than=]
aosp-kernel/private/msm-google/drivers/media/platform/msm/camera_v2/pproc/cpp/msm_cpp.c:4018:13:
error:
stack frame size of 3200 bytes in function
'msm_cpp_subdev_fops_compat_ioctl'
[-Werror,-Wframe-larger-than=]
I have done some searching, but could not find the answer.
Could someone help me with this? Thanks in advance!
Best,
Jimmy
