Hi Fengguang,
I've recently run into a number of cases in which I pulled a branch that
was building fine with "make vmlinux", but that failed for "make dtbs",
and I wonder if this is something that could be checked by the kbuild
test robot so we catch it earlier.
There are parts of this:
- running "make" without a target will build the default image file
and also do the "dtbs" target on ARM and other architectures. I
don't know if this is what you do, or if you always build
"make vmlinux ; make modules", which doesn't include it.
The dtbs makefile target is available on arc, arm, arm64, h8300,
metag, mips, nios2, and xtensa but not the others, so if you
call it explicitly, that has to be in an architecture specific
way.
- setting CONFIG_OF_ALL_DTBS will catch all files, not just the
ones that are built by default for the set of configurations you
have. It's possible to simply override this on the command line,
using "make CONFIG_OF_ALL_DTBS=y", it doesn't actually have to
be part of the configuration. The result is independent of the
actual configuration, so it should be enough to do this once
per architecture and source revision.
Is this something you can add?

Yes, sure.

My typical build command sequences are
make oldnoconfig
make prepare
make headers_install
make ARCH=xxx
make install
So it looks good already. :)

Do you mean to simply change the main "make" command line to
make ARCH=xxx CONFIG_OF_ALL_DTBS=y
Which looks safe even for ARCHs that do not support it.
The arch/.../Makefile that actually use it are:
arch/arc/boot/dts/Makefile
arch/arm/boot/dts/Makefile
arch/arm64/boot/dts/Makefile
arch/h8300/boot/dts/Makefile
arch/metag/boot/dts/Makefile
arch/mips/boot/dts/Makefile
arch/xtensa/boot/dts/Makefile

We initially run "make" without vmlinux, however during bisect more
specific make targets will be used to speed it up. To do that it's
necessary to know the regex patterns of "make dtbs" error messages,
so that they can be correctly bisected.
Can you give some "make dtbs" error messages or patterns?
Thanks,
Fengguang

A typical error looks like
Error: arch/arm/boot/dts/sun7i-a20-bananapi-m1-plus.dts:252.1-18 Label or path usb_power_supply not found
FATAL ERROR: Syntax error parsing input tree
scripts/Makefile.lib:312: recipe for target 'arch/arm/boot/dts/sun7i-a20-bananapi-m1-plus.dtb' failed
make[3]: *** [arch/arm/boot/dts/sun7i-a20-bananapi-m1-plus.dtb] Error 1
There should be almost 100% correlation between seeing "arch/${ARCH}/boot/dts/"
in stderr and having a problem in the "make dtbs" stage.
