To add some context to the above, we've had JIT working on ARM in previous releases of the JVM, but during the release of OpenJ9 we haven't been able to prioritise this platform. At this point OpenJ9 on ARM is mostly untested so some bugs are to be expected, and we also know that there are opportunities for improving the performance.
We hope to work through these issues as resources permit, and we certainly welcome any help along the way!

The build instructions work, I've gotten a build working on a Pandaboard.
kjoshi@arm:~/code$ java -Xgcpolicy:optthruput -Xjit:count=0 Test
Hello World!
kjoshi@arm:~/code$ java -version
openjdk version "9-internal"
OpenJDK Runtime Environment (build 9-internal+0-adhoc..openj9-openjdk-jdk9)
Eclipse OpenJ9 VM (build 2.9, JRE 9 Linux arm-32 20171208_000000 (JIT enabled, AOT enabled)
OpenJ9 - 0de2885

OpenJDK - 1736100 based on 20171201193602-2bf6f7b)

Linux arm 4.10.17-armv7-x2 #1 SMP Thu Nov 30 23:13:59 EST 2017 armv7l armv7l armv7l GNU/Linux
A few minor missing details about the build instructions:
In the build docker image, you'll need to extract the Build JDK at /root/buildjdk
The rest was straightforward. Great stuff.

Hi guys,
happy that the good old J9 found his way to Eclipse and became openJ9.
I am also interested to have this running on ARM, and I was somehow not suprised to meet @kartben over here ;-). We are thinking to use openJ9 in a priductive setup.
@JamesKingdon What do you think is still missing for the ARM version for more than simple testing java apps.
Thanks to all people involved for this great project!
Would be really really great if we could use openJ9 for ARM. I had only great experiences with J9 for embedded Java in a Telematics project.

OK, good news - I managed to manually get a build going, complete with JIT:
OpenJDK Runtime Environment (build 9-internal+0-adhoc.jkingdon.openj9-openjdk-jdk9)
Eclipse OpenJ9 VM (build 2.9, JRE 9 Linux arm-32 20171109_000000 (JIT enabled, AOT enabled)
OpenJ9 - 5e2451c
OMR - 30c2196
OpenJDK - ae4d07b based on jdk-9+181)
The bad news is that the JIT is quite unstable when running anything other than trivial programs. I'll try and work through the issues I raised to get regular builds enabled, and then I'll focus on the JIT stability issues. Realistically, we have quite a lot of work still ahead of us.

Cross-compilation of an OpenJDK JVM is a success, let's see what happens if I replicate the compilation settings for openj9… And I also need to get a working version of qemu-arm to be able to run 'constgen' and 'j9ddrgen' (unfortunately I use MacPorts instead of Homebrew and qemu-arm does not seem to be part of the ports package for qemu.
pi@raspberrypi:/tmp/jdk $ ./bin/java -version

Sorry for the long delay, I'm finding it increasingly hard to get time to work on this. The port is basically working, although there remain a number of failures in the test suites that need to be tracked down (not all of them are necessarily ARM specific, so identifying the subset that are will need to be part of the work).
The main step that needs to be taken to unblock more progress is to move from my unofficial builds on travis-ci to integrating with the project build systems. There is #1159 to track this.

It is wrong, but I don't find any references to aotTarget or aot_target in the OpenJ9 code. I suspect its obsolete and not used any more.
These buildspecs contain obsolete information and settings only useful to IBM internal builds. There is an effort underway to change the builds to use cmake, I expect all the buildspecs will be cleaned up when this conversion occurs.

@AlexBudesteanu, a bit of review and I believe I understand what is happening here. Cross-compiling with openj9 currently generates binaries only for the target images. Technically its attempting to use the target generated binaries on x86 which is the file format error.
Cross-compiling openjdk binaries are generated for the build-jdk (host system) and then for the target images (jdk/jre). Its the generating of the binaries for the build-jdk that isn't incorporated in the openj9 work.
I believe if you re-run configure with --with-build-jdk (path to JDK of same version as is being built), this should workaround that issue. It will also mean a faster compile as it won't be generating an xLinux buildjvm as well. That the build-jdk will need to be at JDK-9+181 tag or later. You can grab a pre-built one from https://adoptopenjdk.net/?variant=openjdk9-openj9.
The build-jdk is used to build the v9 jmods and module, so you cannot use the boot-jdk of java8.
Search cross-compile for more information

Hi @JamesKingdon,
I will try this weekend.

We build an ARM VM from the OpenJ9 code base for Java 8. I haven't heard a build has been tried for Java 9, but it should work. The VM works with -Xint (interpreted only - no JIT) but isn't yet supported by the JIT.
You are welcome to try building it, I expect most or all of the changes required to build it are in the build files found in https://github.com/ibmruntimes/openj9-openjdk-jdk9
i.e. setting the OPENJ9_CPU, OPENJ9_PLATFORM_CODE, OPENJ9_BUILDSPEC (to /buildspecs/linux_arm.spec) in /openj9-openjdk-jdk9/closed/autoconf/custom-hook.m4

so I don't seem to be terribly successful yet. I have very limited JVM knowledge so maybe the following will sound familiar to people?

Right, my apologies. I didn't realize that this time around I had mixed up the args. I had already realized that it didn't work even with JIT properly disabled (didn't pay attention this time) it still fails. See below, without JIT this time, and thanks for the super fast response! 😄
Note: I've switched to a zero variant as I thought this might minimize the lower the chances of running into incompatible assembly code issues but certainly had a similar issue with a "client" build.

BTW isn't 'zero' supposed to be interpreted-only anyways?
from openj9.
JamesKingdon
commented on May 18, 2024
More than that, I believe it is supposed to be free of any assembler code. As far as I know we haven't attempted to support zero yet.
I'm embarrassed to admit I haven't succeeded in compiling for ARM - I ran into an aufs bug that hangs the configure step. Are you doing a cross-compile or compiling native?
from openj9.
kartben
commented on May 18, 2024
@JamesKingdon I am compiling native, I thought it would be simpler (albeit much much slower of course :-)). And my main computer is a Mac anyways and cross compilation of openJDK from MacOS to ARM seems to have many glitches anyways (or I am just doing it wrong :))
from openj9.
jdekonin
commented on May 18, 2024
I am quoting a bit of openjdk-jdk9 common/doc/building.md here, "..A number of pre-defined ABI profiles are available using --with-abi-profile: arm-vfp-sflt, arm-vfp-hflt, arm-sflt, armv5-vfp-sflt, armv6-vfp-hflt. Note that soft-float ABIs are no longer properly supported on OpenJDK."
I believe you will be able to find these options in the ~/Repositories/openj9-openjdk-jdk9/build/linux-arm-normal-zero-release/spec.gmk file at is generated in the configure stage. It would be good to review any other compiler option detailed in the spec.gmk for compatibility with the toolchain you are using.
There is also a specific toolchain openjdk suggests to use within a cross-compile environment. So this might be a challenge for openjdk-jdk9 without openj9. It might be worth testing openjdk9 on its own within the same environment.
from openj9.
kartben
commented on May 18, 2024
@jdekonin Thanks for the hint. Looks like it is actually recommended to cross-compile rather than try and go native, so I guess I will try that. I am not sure what you mean when you say that the specific toolchain they recommend will be a challenge for openjdk-jdk9 without openj9?
FWIW I was building with ABI profile 'arm-vfp-hflt'
from openj9.
jdekonin
commented on May 18, 2024
@kartben, I was just meaning that maybe you should try openjdk on its own as a starting point. The failure you are seeing appears to be in libjava.so which isn't something that is being modified afaik.
from openj9.
pshipton
commented on May 18, 2024
To put it another way: the problem is an Illegal instruction, meaning the options used to compile the code don't match the hardware used to run. The code causing the Illegal instruction is part of OpenJDK (libjava.so), and not OpenJ9. It seems the OpenJDK part of the build needs to change to use a different profile. OpenJ9 is setup to compile ARM for hard float (hflt) and OpenJDK should be built the same way.
from openj9.
kartben
commented on May 18, 2024
Thanks @pshipton. That helps.
Just a random thought, should I be worried that linux_arm.spec has "aotTarget = ia32-linux"?
from openj9.
kartben
commented on May 18, 2024
Makes sense. I couldn't find any reference to aotTarget in the codebase either but thought I would ask :-)
Still working on cross-compiling my vanilla OpenJDK…

commented on May 18, 2024
Just FYI, OpenJ9 doesn't use j9ddrgen. This is turned off as the tools used to build it are not available in the open. Its going to be obsoleted once the dwarf replacement happening in omr is ready.
from openj9.
jdekonin
commented on May 18, 2024
qemu-arm is just an emulator openj9 uses to run constgen because hardcoded as a cross-compile platform. If you open and modify openj9/runtimes/jilgen/module.xml and just run 'constgen' directly that should work. You should see at the bottom of the file...
<command line="cd $(UMA_PATH_TO_ROOT) && ./constgen" type="all">
<exclude-if condition="spec.linux_arm.*"/> <<<---- remove this line
<exclude-if condition="spec.linux_ztpf.*"/>
</command>
remove this section....
<command line="cd $(UMA_PATH_TO_ROOT) && qemu-arm -r '9' ./constgen" type="all">
<include-if condition="spec.linux_arm.*"/>
</command>
I don't have access to a pi atm, otherwise I would verify this works. Thanks for the work you have been putting into getting this going though!!
Update: I was thinking that you were compiling directly on the pi, not cross compiling when I made this comment. If you are going to continue with the cross compile try qemu.org and don't make the modification to above.

@kartben, in case you are just reading the email updates and its confusing, I edited the last comment a few times read it issue itself :)
from openj9.
kartben
commented on May 18, 2024
@jdekonin I am going down the cross compile path now so yeah I do need qemu to run constgen (unless it's a "self-contained" exec and maybe in that case i can run it directly like you suggest by pointing my module.xml at a constgen that I would build for the mac?).
For some reason qemu-arm is not available in the default MacPorts package for qemu, and I am having a hard time compiling my own qemu from source …
from openj9.
kartben
commented on May 18, 2024
@jdekonin and yes of course your suggested change to openj9/runtimes/jilgen/module.xml works just fine, and this is what i was doing when compiling directly on the Pi 😄 BTW I guess the should be improved so that to not try to use qemu if we are already building on an arm machine?
from openj9.
jdekonin
commented on May 18, 2024
@kartben How is the cross compile working for you? Have you had time to investigate further? And to you question above, yes an improvement option for native compilation needs to be added for ARM. I opened #138 for tracking.

@jabrena I don't have a solution yet, but I learned quite a lot about the problems this morning. I'm hoping that the things I found will trigger some ideas from the guys who know the build systems better than I do.

I've reached the illegal instruction stage. It looks to me like we're making a call to thumb code with the processor still in arm mode. In my case the call is coming from ffi_call_VFP and crashes in Java_jdk_internal_reflect_Reflection_getCallerClass__I. I can think of a few ways this could have gone wrong, but I think the simplest would be that some of the files got compiled without the -marm flag.
from openj9.
JamesKingdon
commented on May 18, 2024
I tracked down the problem with thumb code - the native methods in the jdk tree were being compiled for thumb. The problem was caused by passing the wrong abi profile to the configure script. I had been using arm-vfp-hflt which results in -march=armv7-a -mthumb being passed to the compiler. Changing the abi profile to xarmv6-vfp-hflt gives -march=armv6 -marm, which should be compatible with the way that the rest of OpenJ9 is being built. (see flags.m4 in common/autoconf). Debugging this was a lot easier once I could see the compilation commands by using LOG=cmdlines on the make invocation.
On to the next failure...

I can get some non-trivial programs running by using the following options:
-Xjit:disableDirectToJNI -Xgcpolicy:optthruput
The gcpolicy option is to work around missing implementation in the ARM codegen for the array copy evaluator. I've opened an OMR issue to track that problem:
I haven't looked at the JNI direct call problem yet, but the fact the it only takes the two options to get some bigger programs running suggests the code isn't too badly broken after all :)

JamesKingdon
commented on May 18, 2024
Sorry for the slow progress. I'm working my way through the changes to the build and submitting PRs for each. I've also created a docker file that brings together the cross compiler tool chain and the required native libraries.
from openj9.
JamesKingdon
commented on May 18, 2024
Time for another status update. The good news is that we're getting closer. I've submitted the following pull requests that together permit cross compilation from an x86 hosted Docker container:
#622
#686
eclipse/omr#2057
ibmruntimes/openj9-openjdk-jdk9#87
ibmruntimes/openj9-openjdk-jdk9#88
Changes have been requested by the reviewers, so it will take some time to work through those before we finally have working ARM builds in the main code base.
The less good news is that the resulting JVM has functional and performance issues that we need to track down. In some cases there are workarounds that can be applied at the command-line, some of the newer problems we haven't characterized well enough to find a work-around yet.
I wouldn't recommend trying the ARM build for anything other than curiosity or test & development of the JVM at this stage, but if you do want to get an early look, you can get a completely unofficial version by pulling from my personal forks and following the instructions at https://github.com/JamesKingdon/openj9/blob/arm-build-instructions/buildenv/Build_Instructions_V9.md#arm
from openj9.
JamesKingdon
commented on May 18, 2024
I've made another set of changes to the ARM build in response to the PR reviews and updated the instructions to match. I think the only external difference is for building the x86 build JDK locally (the very last and entirely optional section of the instructions), so hopefully it doesn't impact anyone. But if you had started building yesterday and come back to the online instructions today you might find some discrepancies.
from openj9.
JamesKingdon
commented on May 18, 2024
As a result of making all the branches have the same name ('arm') the instructions moved to
https://github.com/JamesKingdon/openj9/blob/arm/buildenv/Build_Instructions_V9.md#arm. I've also switched the build-docker-arm script to build for armv7 by default, but haven't had time to describe that in the instructions. If you need armv6 either edit the script or don't use the script and follow the instructions for configuring and compiling in separate stages.
from openj9.
JamesKingdon
commented on May 18, 2024
Hey @kaiwalyajoshi , that's great news - many thanks for trying it out.
In the instructions I go for unpacking the build JDK outside of the docker image and then mounting it as a volume.
Extract it into the working directory along side openj9-openjdk-jdk9
tar xf OpenJDK9-OPENJ9_x64_Linux_20172711.tar.gz
docker... -v <path to working dir>/jdk-9+181:/root/buildjdk ...
I can see it would look more natural to have the build JDK handled inside the docker image like other dependencies. The current state of play stems from a combination of a separate build JDK being a temporary fix until we can get it automatically created during the normal build process, and the fact that there isn't a 'latest-nightly' link that I could easily use to automate the installation. Weak arguments I know - I'll take another look at the setup and see if I can smooth this out.
Edit: Ah, but the comment in the Dockerfile doesn't mention the volume for the build jdk. I need to make things consistent, one way or another!
Thanks again for the feedback.

JamesKingdon
commented on May 18, 2024
I've updated the build-docker-arm script (and .travis.yml) to use the official repos for OpenJ9 and omr-openJ9. This has the advantage of getting the latest changes for those repos, and the disadvantage of not having some of my recent fixes for arm, so you need to use disableDirectToJNI, and it's built for armv6 instead of armv7. Travis.ci is setup to put the binaries in the releases section of my openj9-openjdk-jdk9, so you can pick up either a jdk or jre from https://github.com/JamesKingdon/openj9-openjdk-jdk9/releases/tag/20171217193531-f232f3a6
Remember that they are still strictly unofficial and mostly only useful for testing and further development.

Hi @JamesKingdon,
I'd like to suggest a cleanup in linux_arm_docker.spec. It has issues like an enabled IA32 codegen, which IMHO shouldn't be enabled for ARM. It's not only in the new version, linux_arm.spec has the same issues.
These files contain architecture-dependent stuff about what I know nothing about, so I can't help you much.
Regards

Hi @JakubVanek, agreed, I think there's some clean-up needed in those files. Possibly they will get revamped as part of the move to CMake. Thanks for pointing it out.

commented on May 18, 2024
Hi @marziman thanks for your post and encouragement :)
We need to get the build into our regular build & test cycle to shake out any remaining bugs. The known functional issues have been identified and addressed by @knn-k and are either in the code base or on their way. Which leaves us with performance - definitely not where we want it to be yet, so we need to characterise the problems and prioritise improvements.
Further out, we obviously are aware of the need for a 64bit implementation and exploitation of more hardware features.

Great thanks @JamesKingdon !
So can you give me a ping as soon I can test out our Java OSGi platform on top of ARM J9?
If you feel more comfortable and think you have a certain stability. Much thanks for your and @knn-k efforts and work.
Would be great.

Hi @marziman
I'll try and remember to let you know when we've made some progress. If nothing else, this issue will get updated as things move forward. I'm afraid it may not be as quick as I'd like, as we're still figuring out how to prioritise the different parts of the project, and there's a whole lot of work on the list!
