Hey all, As discussed and agreed upon during our November Developer meeting (https://github.com/orgs/gem5/discussions/482), we have scheduled the creation of our staging branch from `develop` for December 1st. This means **gem5 developers have until December 1st to have their contributions

[gem5-dev] Re: Build failed in Jenkins: nightly #403

At least one problem here is the Nightly tests are failing due to it reaching timeout. I've submitted some patches here to remove some of the Boot tests (we have a lot of these, they take a while to run, and are largely doing the same thing), remove a couple of tests that require compilation of

[gem5-dev] v22.1 staging branch ready. RELEASE_NOTES.md requiring feedback

I don't know exactly what patch triggered this bug, but gcc-12 was failing to compile gem5 due to a missing virtual destructor in GlobalSyncEvent. This patch should fix the problem: https://gem5-review.googlesource.com/c/public/gem5/+/66152 -- Dr. Bobby R. Bruce Room 3050, Kemper Hall, UC Davis

[gem5-dev] v22.1 Staging branch created

Dear all, As of this afternoon, the gem5 v22.1 staging branch has been created. This branch will be intensely tested over the next couple of weeks to ensure it's ready to be merged into the stable branch. If you have any bug fixes you can submit them to the develop branch then cherry-pick the

[gem5-dev] Re: Build failed in Jenkins: nightly #413

It turns out this patch: https://gem5-review.googlesource.com/c/public/gem5/+/64831 is greatly increasing the Linux boot times and therefore causing the timeouts to occur. I'll try to find a solution for this. Unfortunately reverting the patch isn't an option, changing the CPUID is necessary to

[gem5-dev] Our use of Python Ply is incompatible with Python 11

Hey all, In November 2022 Python 3.11 was release and is slowly being rolled out for usage. In January of this year I became aware of an issue which makes gem5 incompatible with Python 3.11. I’ve outlined my findings, in detail, here: https://gem5.atlassian.net/browse/GEM5-1321. In brief,

The following patch should fix this nightly bug: https://gem5-review.googlesource.com/c/public/gem5/+/69717 There was a small bug introduced where header files were not being added to the “build” directory. This broke the SST compilation as it uses the “build” directory as a include path. In

[gem5-dev] Re: Building on Apple Silicon / ARM docker

Hey, I believe I’ve run into this issue before on my Apple machine and have a solution. I am running on the assumption here your Python installation is 3.11. That’s the only reason I can see as to why you’d have this problem (this email may be pretty pointless if this assumption isn’t true).

The two patches in this relation-chain should fix the compilation error: https://gem5-review.googlesource.com/c/public/gem5/+/69598 In short: the CPP Filesystem library needs a couple of work-arounds to compile successfully with GCC Versions 7 and 8. -- Dr. Bobby R. Bruce Room 3050, Kemper

[gem5-dev] Re: Build failed in Jenkins: nightly #566

I don’t know the exact cause of this problem but it’s a Docker failure of some kind and likely not due to any actual test failure. These just happen very so often on our Jenkin’s setup and they are impossible to recreate locally. It could be Docker running out of member (though it should have

[gem5-dev] Re: Build failed in Jenkins: nightly #509

Gabriel, It looks like the nightly tests failed due to some of the ports not being updated correctly. Do you have time to look into this and fix it? Kind regards, Bobby -- Dr. Bobby R. Bruce Room 3050, Kemper Hall, UC Davis Davis, CA, 95616 web: https://www.bobbybruce.net On Fri, Feb 3, 2023

[gem5-dev] Re: Build failed in Jenkins: nightly #659

This appears to be a Docker failure of some kind. Both the compiler and nightly tests dropped at the same time. I think the Docker daemon crashed for some reason No tests failed here. The patches submitted yesterday don’t interact with any tests so they should all still pass. I’ll re-run

[gem5-dev] Hotfix v23.0.0.1: To fix GCN3_X86 compilation

Dear all, I’m planning a hot fix to the v23.0.0 release to address an error found. The issue was highlighted here https://gem5.atlassian.net/browse/GEM5-1332. In short, the v23.0.0.0 release can’t compile the “build/GCN3_X86/gem5.opt” binary. This came about as we cherry-picked some GPU
