While doing parallel builds using "make -j" option, I ran into a build race condition a few times where-in Image.gz-dtb target starts building before Image.gz is even ready, resulting in a corrupt Image.gz-dtb kernel image. How to reproduce --> $ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-androidkernel- defconfig menuconfig + CONFIG_BUILD_ARM64_APPENDED_DTB_IMAGE=y CONFIG_BUILD_ARM64_APPENDED_DTB_IMAGE_NAMES="qcom/apq8096-db820c" $ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-androidkernel- -j9 <snip> .. SYSMAP System.map OBJCOPY arch/arm64/boot/Image GZIP arch/arm64/boot/Image.gz DTC arch/arm64/boot/dts/qcom/apq8096-db820c.dtb Building modules, stage 2. CAT arch/arm64/boot/Image.gz-dtb GZIP arch/arm64/boot/Image.gz .. <snip> $ du -sh arch/arm64/boot/Image.gz-dtb 28K arch/arm64/boot/Image.gz-dtb When built with this patch --> $ du -sh arch/arm64/boot/Image.gz-dtb 8.9M arch/arm64/boot/Image.gz-dtb Let's make Image.gz-dtb build target depend on Image.gz explicitly.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
