How to build your kernel:
|
|
|
|
Prerequisites:
|
|
|
|
* ramdisk.img - root fs
|
|
|
|
* mkbootimg - boot.img generator
|
|
|
|
* The ARM cross-compiler
|
|
You can use prebuild executable binary which is included in
|
|
standard Android repository. Please visit to external site.
|
|
In case of this platform, we recommend to use gcc 4.9 or later
|
|
such as aarch64-linux-android-4.9 to avoid known issues.
|
|
|
|
|
|
Step 1: Build Your Kernel
|
|
$ cd kernel
|
|
|
|
$ export ARCH=arm64
|
|
|
|
$ export PATH=<path-to-cross-compiler-executables>:$PATH
|
|
NOTE: Please set the location of the ARM cross-compiler.
|
|
|
|
$ export CROSS_COMPILE=<toolchain-prefix>
|
|
NOTE: Please set the prefix of the ARM cross-compiler.
|
|
ex) aarch64-linux-android-
|
|
|
|
$ export KBUILD_DIFFCONFIG=sumire_diffconfig
|
|
NOTE: Please set a configuration file you want to build.
|
|
|
|
$ make msm8994-perf_defconfig
|
|
|
|
$ make
|
|
|
|
You can see arch/arm64/boot/Image.gz-dtb if you succeed in building.
|
|
|
|
|
|
Step 2: Assembling the boot.img
|
|
(In the Linux Kernel directory)
|
|
$ mkbootimg \
|
|
--kernel arch/arm64/boot/Image.gz-dtb \
|
|
--ramdisk ramdisk.img \
|
|
--cmdline "androidboot.hardware=qcom user_debug=31 msm_rtb.filter=0x237 ehci-hcd.park=3 lpm_levels.sleep_disabled=1 boot_cpus=0-5 dwc3_msm.prop_chg_detect=Y coherent_pool=2M dwc3_msm.hvdcp_max_current=1500" \
|
|
--base 0x00000000 \
|
|
--pagesize 4096 \
|
|
--ramdisk_offset 0x02000000 \
|
|
--tags_offset 0x01E00000 \
|
|
--output boot.img
