On Thu, Oct 06, 2022 at 09:36:22AM -0700, KernelCI bot wrote:
The KernelCI bisection bot found a boot regression on qemu in today's
-next for a multi_v7_defconfig with additional debug options running on
virt-gicv3 which it identified as being triggered by 5750121ae738
("kbuild: list sub-directories in ./Kbuild") which does seem surprising
but the bot did test a revert so it seemed worth reporting.
In the failing boot we do see warnings triggered at:
WARNING: CPU: 0 PID: 0 at arch/arm/kernel/insn.c:48 __arm_gen_branch+0x80/0x88
WARNING: CPU: 0 PID: 0 at kernel/trace/ftrace.c:2120 ftrace_bug+0x320/0x38
WARNING: CPU: 0 PID: 1 at include/linux/cpumask.h:110 smp_call_function_many_cond+0xcec/0xf7c
before the boot hangs at:
<6>[ 35.875754][ T1] Using buffer write method
<7>[ 35.876786][ T1] erase region 0: offset=0x0,size=0x40000,blocks=256

I've left the full report including a tag for the bot and links to
things like full build logs below:

I found it in the qemu manual:
https://www.qemu.org/docs/master/system/arm/virt.html?highlight=gic%20version
The arm virt machine with gicv3 booted as far as I tested.
So, I need to know more details about the settings of the KernelCI.
This is my qemu command line.
qemu-system-arm -machine virt,gic-version=3 \
-kernel /home/masahiro/tools/qemu-arm_virt/kernel \
-initrd /home/masahiro/tools/qemu-arm_virt/initrd \
-drive file=fat:rw:/home/masahiro/tools/qemu-arm_virt/disk-shared,if=none,format=raw,id=drive0
\
-netdev bridge,id=netdev0,br=virbr0,helper=/usr/lib/qemu/qemu-bridge-helper \
-serial stdio -monitor vc:800x600 -cpu cortex-a15 \
-smp 4 -device virtio-blk-pci,drive=drive0 \
-device virtio-net-pci,netdev=netdev0 -append console=ttyAMA0
This is the boot log on my local test.

You need to pass a firmware image as well.

https://snapshots.linaro.org/components/kernel/leg-virt-tianocore-edk2-upstream/4666/QEMU-ARM/RELEASE_GCC5/QEMU_EFI.fd
(the firmware execution can be quite slow under emulation so give it some time)

The HTML versions of the boot logs include the qemu command, these days
it's run using docker so so you can even get the specific version of
qemu version that was being used by kernelci in case that's important:
docker run --network=host --cap-add=NET_ADMIN --interactive --tty --rm --init --name=lava-docker-qemu-7496529-2.1.1-gexyjab5hb --device=/dev/kvm --device=/dev/net/tun --mount=type=bind,source=/var/lib/lava/dispatcher/tmp,destination=/var/lib/lava/dispatcher/tmp kernelci/qemu qemu-system-arm -cpu cortex-a15 -machine virt-2.11,gic-version=3 -nographic -net nic,model=virtio,macaddr=DE:AD:BE:EF:45:5C -net bridge,br=virbr0 -m 1024 -monitor none -kernel /var/lib/lava/dispatcher/tmp/7496529/deployimages-blwzkdvs/kernel/zImage -append "console=ttyAMA0,115200 root=/dev/ram0 debug verbose console_msg_format=syslog earlycon" -initrd /var/lib/lava/dispatcher/tmp/7496529/deployimages-blwzkdvs/ramdisk/rootfs.cpio.gz -drive format=qcow2,file=/var/lib/lava/dispatcher/tmp/7496529/apply-overlay-guest-f5mnvw0l/lava-guest.qcow2,media=disk,if=virtio,id=lavatest
Everything from qemu-system-arm on is the command that's run inside the
container.
The logs also show the download of the filesystems that would be used,
though we don't get as far as actually using them so it's a bit moot:

I suspect "+debug" in "multi_v7_defconfig+debug"
because the failure log says "ftrace bug" multiple times.
Which config options does "+debug" enable?
Can you share the .config file?

The baseline config and fragment are both in:

Thanks for sharing the .config file.
With it applied, I can reproduce the boot error.
And, I see the same boot error on v6.0-rc7, which my branch is based on.
So, arm is already broken in the mainline, and
my kbuild patches are irrelevant.
Also, please check the bisection logic of kernelci.
I attached the boot log of v6.0-rc7 below.
("Linux version 6.0.0-rc7" in the kernel log)
Thanks.

I *suspect* there's some involvement from link ordering, object sizes
and exact placements here and there's probably some toolchain variance
(the KernelCI results are with Debian's GCC 10).

Different GCC versions result in different machine code output.
If the problem repeats appear/disappear with slightly different code
placement, it is already broken.
Just in case, I removed the output tree, and built v6.0-rc7 kernel
from the clean tree. I swear to see the boot failure.
I want to agree my patch is not the cause of the issue.
