buildman stops (crashed) on current master
Hi all,
CI stops by building aarch64 without notice, for reference:
https://source.denx.de/u-boot/custodians/u-boot-imx/-/jobs/332319
There is no error, just process is killed. It looks like it stops at xilinx_zynqmp_virt,
./tools/buildman/buildman -o /tmp -P -E -W aarch64but board can be built without issues.
If I build on my host (not in docker, anyway), it generally builds fine - but it crashes sometimes, too. On gitlab instance , it crashes. Issue does not seem that depends on merged patches, and introduces boards were already built successfully. Any hint ? I have also no idea what I should look as what I see is just
"usr/bin/bash: line 104: 24 Killed ./tools/buildman/buildman -o /tmp -P -E -W aarch64"

I cannot see that link. I am not sure what is going on. Does it say what signal killed it?
Does it sit there for an hour and timeout? If so, then I did see that myself once recently, when the Kconfig needed stdin, but I could not quitetie it down. I think buildman would provide it, but sometimes not, apparently. So it can happen when there is an existing build there and your new one which adds Kconfig options that don't have defaults, or something like that?
If that is it, you can repeat it by clearing out your .bm-work directory then building just that board for one commit, then the next (with the Kconfig change).
Buildman is supposed to handle this, of course. I'm not sure what has changed.

Verified with Wolfgang. The CI's results are available only after having logged in to source.denxe.de. Without account, they are not shown and the server return not found (I was not aware of this).
I am not sure what is going on. Does it say what signal killed it?
Nothing, that makes an investigation difficult. It looks like it is bound (resource issue ?) with the runner or docker instance, because if I run the same buildman command on my host, it works until end and no errors are reported:
aarch64: w+ xilinx_zynqmp_virt
+===================== WARNING ====================== +This board uses CONFIG_SPL_FIT_GENERATOR. Please migrate +to binman instead, to avoid the proliferation of +arch-specific scripts with no tests. +==================================================== +WARNING: BL31 file bl31.bin NOT found, U-Boot will run in EL3 125 181 0 /306 xilinx_zynqmp_virt
gitlab stops exactly with the last board, as if all work was done, but rather after a timeout and pipeline is set to failed (just a feeling).
Does it sit there for an hour and timeout? If so, then I did see that myself once recently, when the Kconfig needed stdin, but I could not quitetie it down. I think buildman would provide it, but sometimes not, apparently. So it can happen when there is an existing build there and your new one which adds Kconfig options that don't have defaults, or something like that?
But anytime there is a new docker instance on gitlab runner, so this could happen only on local host.
If that is it, you can repeat it by clearing out your .bm-work directory then building just that board for one commit, then the next (with the Kconfig change).
Buildman is supposed to handle this, of course. I'm not sure what has changed.
Ok, let's see.

Pipelines on our server were not public - I have enbaled now for u-boot-imx.

I have investigated further, and I can reproduce it on my host outside the gitlab server. buildman causes a OOM, but I cannot find the cause.
Strange enough, this happens with the "aarch64" target, and I cannot reproduce it with Tom's master. So it seems that -master is ok, and somethin on u-boot-imx generates the OOM.
However....
The OOM happens always when -2 (two boards remain) appears. I can see with htop that buildman starts to allocate memory until it is exhausted (64GB RAM + 8 GB swap). Then the kernel decides that it is enough and kills buildman - this is what I see on Ci.
You can see now the pipelines:
https://source.denx.de/u-boot/custodians/u-boot-imx/-/pipelines/9520
I have then split aarch64 and I built imx8 separately - same result. The pipeline stops with xilinx board, but they have nothing to do. In fact, I can build all xilinx board separately. If I run buildman -W aarch64 -x xilinx, OOM is shown by another board.
Strange enough, I can build each single board with buildman without issues, neither errors nor warnongs. Just when buildman runs all together (aarch64, 308 boards), the OOM is generated.
Bisect does not help: I started bisect, and at the end this commit was presented:

But it is a fake: I can revert it, I get the issue again. And the patch has nothing to do.
It looks to me it is something in binman, maybe triggered by some changes in tree, but all boards can be built separately without issues. I supposed to find the cause in code due to applied patches, but because each board can be built and no help from bisect, I am quite puzzled. I avoid to send a PR to Tom, else I guess the problem goes into -master, but I do not know how to proceed, and I have a lot of patches to be applied.

If that is it, you can repeat it by clearing out your .bm-work
On gitlab, the build starts from scratch.
Can you check that there is definitely nothing around from the previous build?
On my host, there is definitely something - because I cannot access the docker image on the server, I installed a local runner on my PC. So I can take a deeper look and jump on the container.
It runs, and I get the same issue. All boards are built, then it stucks until OOM happens and kernel kills it.
The job for aarch64 is:
./tools/buildman/buildman -o /tmp -P -E -W aarch64
and it runs in Tom's image. If I jump in the container (without running buildman), there is no .bm-work at all (this should be in /tmp, right ?)
uboot@e4a810aa6d8a:/$ ls -la tmp/ total 8 drwxrwxrwt 1 root root 4096 Sep 30 15:54 . drwxr-xr-x 1 root root 4096 Oct 19 20:01 ..
So it is sure, before buildman runs there is no .bm-work. Then of course, after each job (defined in .gitlab-ci.yml), /tmp/.bm-work is present. But I guess you do not mean to drop .bm-work after each job, right ? Else this should be also put in .gitla-ci.yml.
Where build stucks...I do not know, but it looks like that all boards were already built successfully (just as example https://source.denx.de/u-boot/custodians/u-boot-imx/-/jobs/337915).
directory then building just that board for one commit, then the next (with the Kconfig change).
I have run buildman for each single board, all of them were successuful. With aarch64, I get OOM from buildman.

I still believe this is due to the reason I said,
I am sure you're right, but I do not see any .bm-work before running buildman. Is there something I can turn on to get more info ?
but I'm happy to be proved wrong.

imx8mm-cl-iot-gate: Split the defconfigs
I strongly suspect what's going on here is that these new defconfigs are out of sync with changes now in Kconfig. The build itself will just sit there, waiting for the "oldconfig" prompt to be answered.
I want to say the problem here is that stdin is open, rather than pointing to something closed and would lead to the build failing immediately, rather than once a timeout is hit, or OOM kicks in due to kconfig chewing up all the memory.

Yes that's exactly what I saw...
In fact, see this commit:

But that was 3 years ago.

However....
The OOM happens always when -2 (two boards remain) appears. I can see with htop that buildman starts to allocate memory until it is exhausted (64GB RAM
- 8 GB swap). Then the kernel decides that it is enough and kills buildman -
this is what I see on Ci.
You can see now the pipelines:
https://source.denx.de/u-boot/custodians/u-boot-imx/-/pipelines/9520
I have then split aarch64 and I built imx8 separately - same result. The pipeline stops with xilinx board, but they have nothing to do. In fact, I can build all xilinx board separately. If I run buildman -W aarch64 -x xilinx, OOM is shown by another board.
Strange enough, I can build each single board with buildman without issues, neither errors nor warnongs. Just when buildman runs all together (aarch64, 308 boards), the OOM is generated.
Bisect does not help: I started bisect, and at the end this commit was presented:

imx8mm-cl-iot-gate: Split the defconfigsI strongly suspect what's going on here is that these new defconfigs are out of sync with changes now in Kconfig. The build itself will just sit there, waiting for the "oldconfig" prompt to be answered.
I want to say the problem here is that stdin is open, rather than pointing to something closed and would lead to the build failing immediately, rather than once a timeout is hit, or OOM kicks in due to kconfig chewing up all the memory.
Yes that's exactly what I saw...
In fact, see this commit:
e62a24ce27a buildman: Avoid hanging when the config changes
But that was 3 years ago.
Looks like something else needs to be changed then, I've bisected down similar failures here before very recently.

Hi all,
CI stops by building aarch64 without notice, for reference:
https://source.denx.de/u-boot/custodians/u-boot-imx/-/jobs/332319
There is no error, just process is killed. It looks like it stops at xilinx_zynqmp_virt,
./tools/buildman/buildman -o /tmp -P -E -W aarch64but board can be built without issues.
If I build on my host (not in docker, anyway), it generally builds fine
- but it crashes sometimes, too. On gitlab instance , it crashes.
Issue does not seem that depends on merged patches, and introduces boards were already built successfully. Any hint ? I have also no idea what I should look as what I see is just
"usr/bin/bash: line 104: 24 Killed ./tools/buildman/buildman -o /tmp -P -E -W aarch64"
I cannot see that link. I am not sure what is going on. Does it say what signal killed it?
Pipelines on our server were not public - I have enbaled now for u-boot-imx.
Does it sit there for an hour and timeout? If so, then I did see that myself once recently, when the Kconfig needed stdin, but I could not quitetie it down. I think buildman would provide it, but sometimes not, apparently. So it can happen when there is an existing build there and your new one which adds Kconfig options that don't have defaults, or something like that?

I dug into this a bit and I think buildman can detect this situation. I'll send a little series.

Patch definetly help ;-)
It breaks build (on CI when build-tools runs), but I get much more details when I build locally single boards. I can find for kontron-sl-mx8mm several errors due to:
- CONFIG_SYS_LOAD_ADDR not defined in configs, but in header - CONFIG_SYS_EXTRA_OPTIONS instead of CONFIG_IMX_CONFIG - CONFIG_SYS_MALLOC_LEN not defined in config, but in header
Your patch are a valueable tool (CI driove me crazy), I can now folow what happens. I send a patch for kontron, and I go on with the rest (I guess kontron is not the only board causing this deadlock). Many thanks !
Tom, I apply Simon's patches on my tree, I cannot work without them...

OK good. Unfortunately this is likely to throw up problems that are only fatal 1% of the time.
