In fairness, I think the tests should ideally pass regardless as to where they are executed from, but that's not a priority right now :). -- Dr. Bobby R. Bruce Room 3050, Kemper Hall, UC Davis Davis, CA, 95616 web: https://www.bobbybruce.net On Wed, Oct 13, 2021 at 11:19 AM Matt Sinclair wrote

Hey Gabe, It seems like both the Nightly and Compiler tests are failing because SPARC no longer compilers. This appears to be due to this change: https://gem5-review.googlesource.com/c/public/gem5/+/48717. It looks like you changed "checkFpEnableFault" to "checkFpEnabled" and didn't update this ev

Hey Gabe, The gem5 GUI code is still around, it's on a separate branch in the repo, `feature-gui`: `git clone -b feature-gui https://gem5.googlesource.com/public/gem5`. We at UC Davis tried to get some students to continue working on this, but we were never able to. Hopefully we can get someone t

[gem5-dev] Re: failing kvm tests

Hey Gabe, At present our Jenkins doesn't have KVM enabled so I believe no tests that use KVM were being run regularly. I intend to get KVM enabled on the Jenkins server over the next few days. I also found the bugs you were referring to when running the long (nightly) and very-long (weekly) tests

[gem5-dev] Re: multi-ISA gem5 proof of concept

Looks good to me. Perhaps this is explained elsewhere, but what's the logic in coupling the CPU Type (Timing, Atomic, o3) with the ISA? Why do we interact with this like `--cpu-type=X86AtomicSimpleCPU` and not `--cpu-type AtomicSimpleCPU --isa=X86`? Current CPU types are switchable during a simula

Dear all, Here at UC Davis two undergraduate students, Melissa Jost and Laura Hinman, have been working on incorporating LupIO devices into gem5. For those unaware, LupIO devices were developed by Prof. Joel Porquet-Lupine as a set of open-source I/O devices to be used for teaching. They were des

I agree the TestLib framework is broken when it comes to reporting output, which makes problems pretty difficult to figure things out. As far as I know, it's been this way for some time. My workflow when i get a failing test is to use `./main.py run --uid ` on the failing test suite which, when run

Just checked v19 and it seems that, in this release, failing tests would output stderr and stdout to .testing-results, but if memory serves this was flakey. I _think_ the output wasn't recorded if gem5 crashed, which is a very common cause for test-case failure. In v20 nothing is recorded. If I ha

[gem5-dev] Re: Change in gem5/gem5[develop]: mem-cache: Create Compressor namespace

Just an FYI on this: The nightly builds don't clean the gem5 directory before pulling and recompiling. This saves us some build time. Obviously for stuff like this, we need a work around. I've therefore tweaked the building scripts with stuff like this: ``` scons build/ARM/gem5.opt -j4 || (rm -rf

Dear all, Back when we moved from the master branch being under constant development to a dual "master-as-stable" and "develop" branch setup, there was talk of renaming the master branch. Though, at this time, it seemed unconventional so avoided doing so. In the past few months there has been grea
