Enable JITLink in aarch64 linux. #49745

giordano · 2023-05-10T23:02:52Z

Reland of #45859, which had some conflicts with f11bfc6 (#49530). I hope I got the logic right. CC: @sunho.

Fix #42295, fix #47399, fix #41852, fix #49474.

@vchuravy @pchintalapudi just to be sure: if we're using a sanitizer with LLVM 15+ you want to force JITLink? I think we may want to remove defined(_CPU_AARCH64_) here and handle that below?

Yes we want JITLink if santitizers are enabled on >= 150000, because we hit a bug in our memory manager for Rtdyld. I'm not opposed to handling that below.

@pchintalapudi the only listener integration that is missing is the perf one right? GDB works with JITLink on 15?

pchintalapudi · 2023-05-10T23:27:02Z

Oh we might want #47037 since we need a different plugin for ELF debugger support.

sunho · 2023-05-11T04:41:09Z

Looks good to me regarding the code here!

pchintalapudi · 2023-05-11T17:13:06Z

Might just want to rebase with master since #47037 just merged.

pchintalapudi · 2023-05-11T21:28:43Z

Looks like we're running out of memory of the aarch64 tester?

oschulz · 2023-05-12T09:08:34Z

Would this be a 1.9 backport candidate?

giordano · 2023-05-12T09:13:01Z

This requires LLVM 15, so no.

oschulz · 2023-05-12T09:16:24Z

This requires LLVM 15, so no.

Oh, right! :-) Sorry, should have looked more closely.

minecraft2048 · 2023-05-15T02:30:57Z

Do we have a compiled build for this PR? I want to see if this fixes #49474 as I want to get qemu working

giordano · 2023-05-15T06:51:12Z

Go to the aarch64-linux-gnu build job and open the artifacts tab: https://buildkite.com/julialang/julia-master/builds/23816#01880bd0-6922-44b0-b77c-67fcaf2c1c66

I captured with rr on an M1 MacBook running Asahi Linux the crash (for the record, Base.runtests("LinearAlgebra/triangular") is enough to reproduce the error)

For anyone interested with playing with the the trace: trace.tar.xz. It fails on Complex{BigFloat} but removing the other types makes the crash go away.

giordano · 2023-06-08T21:45:45Z

Reporting here the progress discussed on Slack. @gbaraldi figured out what was the problem: this issue in Java reported a similar ENOMEM error on mprotect, and it was suggested that the the application was creating too many mappings, exceeding the limit in /proc/sys/vm/max_map_count. He also noticed that running the LinearAlgebra tests creates over 71k mappings (wc -l /proc/$$/maps, where $$ is the PID of the process), while in many systems the default limit is 65530. We increased the limit of mappings on the CI machine with sysctl -w vm.max_map_count=262144 (not sure what's the value actually used) and the restarted job is finally passing all the tests 🥳 This problem is not specific to aarch64, also using JITLink on x86_64 results in several thousands of mappings open. As far as I understand this is an upstream bug in LLVM (?) memory manager.

Not sure where to go from here. Document the possibility of having to increase the memory mappings limit and merge this PR? Linux aarch64 is tier 2 and currently suffers from many segmentation faults anyway (although those should be solved by JITLink, enabled with this PR), so situation wouldn't be much worse.

pchintalapudi · 2023-06-08T22:06:48Z

I'm in favor of merging and documenting the memory mapping limit issue+resolution in the release notes. The memory manager issues aren't likely to be fixed in the near term, and resource limits are easier to fix than segmentation faults.

gbaraldi · 2023-06-08T23:40:09Z

Yeah, I'm fine with merging too. The issue is common to all platforms that use JITLink, it seems it just reared it's head here, the solution for the user is pretty easy, but it probably requires quite a bit of LLVM work.

vchuravy · 2023-06-09T00:37:46Z

Agreed! We should add a news entry, and additional an entry in the docs.

Do we have an upstream issue number?

gbaraldi · 2023-06-09T01:10:50Z

There isn't an upstream issue just yet.

giordano · 2023-06-09T19:10:09Z

and additional an entry in the docs.

Do you refer to the explanation of the work around potentially needed to increase the limit of mappings? Where do you suggest to place it specifically?

There isn't an upstream issue just yet.

Is there one now?

vtjnash · 2023-06-09T19:57:37Z

This is not an issue with our existing cgmemmgr, so it seems like this is something that should be fixed upstream

giordano · 2023-06-10T00:15:24Z

This is not an issue with our existing cgmemmgr, so it seems like this is something that should be fixed upstream

Yeah, I was wondering if @gbaraldi opened a ticket upstream in llvm so that we can add a reference to it in the docs.

giordano · 2023-06-11T15:31:04Z

I added the NEWS entry and mentioned the ticket opened by Gabriel in the ARM build devdocs page. Please check if it's all OK.

Anything else to do this for this PR? 🙂

gbaraldi · 2023-06-11T15:34:30Z

LGTM

This seems to happen when exiting the process, but haven't been able to debug yet because GDB crashes (see the last line, that assertion is GDB's). So I'm not sure it's related, but it does at least point to the JIT.

That segfault is happening everywhere :(

I'm in favor of merging and documenting the memory mapping limit issue+resolution in the release notes. The memory manager issues aren't likely to be fixed in the near term, and resource limits are easier to fix than segmentation faults.

tho this is not simple to do on non-rooted android, right?

additionally does windows allow you to increase such limit?
