[gem5-users] Re: Need Help For Applying a Patch

Hey Srikrishna, I had a look into this for you. Turns out we still had an old gem5 mercurial repo hanging around for us to see where this patch goes. To apply this patch on our git repo you'll need to checkout revision 6498ccddb2f13a6fac6a210372b1aa86873507b9, then use `git apply` with the

[gem5-users] gem5 v20.1.0.2 Hotfix Release

Dear all, We've fixed two bugs as part of a hotfix release for gem5 v20.1. A "ValueError: invalid literal for int() with base..." error was being thrown in certain circumstances due to a non-integer being passed to "MemorySize" via a division. This has been fixed. An assertion in Stats was

[gem5-users] Re: How to display the microop in the reorder buffer for gem5?

Hey, I think the method that may help you here is `disassemble` in static_inst.hh: https://gem5.googlesource.com/public/gem5/+/refs/tags/v20.1.0.1/src/cpu/static_inst.hh#340. I imagine, what you want to do is something like `print (*address).disassemble()`. It may also be worth looking into the

[gem5-users] Re: The latest gem5 did not compile successfully

Hey, These warnings are fine (I get them), they won't affect what you're trying to do. The compilation was successful. I see Hoa is already handling your "When gem5 is debugged, how to judge the current position of data?" question (

[gem5-users] Re: The latest gem5 did not compile successfully

Hey Yujiecui, Sorry to hear you're having trouble compiling. It doesn't sound like you're anything wrong based on what you described. One thing that's always worth trying when having compilation issues with gem5 is deleting the "build" directory and starting from scratch. Sometimes the build

[gem5-users] gem5 v20.1.0.1 Hotfix Release [Garnet Network Model]

Dear all, In the gem5 v20.1.0.0 release there was a bug in the Garnet Network Stats, which adversely affected the overall behavior of the Garnet Network Model. The bug, and related fix, are discussed here: https://gem5-review.googlesource.com/c/public/gem5/+/36416. On November 6th, we applied

[gem5-users] Re: How to enable dist-gem5 on GEM5 20.0.0.3 on ARM64

Hey Liyichao, I'm sorry to somewhat avoid answering the question (I don't know enough about dist-gem5 to comment), but dist-gem5 is grossly under-tested and hasn't had any decent maintenance in a while, so it really comes with no guarantees, and it wouldn't surprise me at all if it doesn't work

[gem5-users] Re: Need help in building gem5

Hey Raghul, I sorry can't tell immediately from this information what's wrong with your process, but I'd advise trying the following steps: 1) Ensure HDF5 is set up correctly on your system. Perhaps you're using an old version? Try reinstalling it and see if that works. 2) If you haven't

[gem5-users] Re: Some Question About Cache in Gem5

Hey, I'm not sure I understand exactly what you're asking. I assume you're learning from the "learning gem5" tutorial (here : http://www.gem5.org/documentation/learning_gem5/introduction/)? If so, could you point us towards the exact part that's confusing you? Kind regards, Bobby -- Dr. Bobby

[gem5-users] Re: gem5 full system emulation is slow - want suggestions to fasten bootup

Hey Krishnan, I know very little about Ciro Santili's scripts, so I struggle to see what you're doing. I suspect in this example you are _just_ booting the kernel with literally nothing else (and possibly on the Atomic CPU?). This will be faster than a complete OS boot, but I normally run on the

Hey Farhad, I've added a Jira ticket about this bug: https://gem5.atlassian.net/browse/GEM5-798. I'm afraid to say we don't have a solution right now, but we suspect it may be similar to this bug: https://gem5.atlassian.net/browse/GEM5-332. You can see the comments on this bug for more

[gem5-users] Re: gem5 full system emulation is slow - want suggestions to fasten bootup

Hey Krishnan, Linux does take about 45 minutes or so to run using AtomicSimpleCPU. You're not doing anything wrong in this regard. I'm afraid there's no information I can give you on making it faster. Anything to make this significantly faster, would be sacrificing the accuracy of simulation.

[gem5-users] Re: FS mode partial reset stats

Hey Maxime, As far as I can tell, this is not expected behavior and may be a bug. To properly log this, and recreate it, could I bother you for a few more pieces of information?: - What version of gem5 are you using? - What OS are you using and what compiler did you compile with (probably not

We have a SystemC interface in gem5. I'm afraid to say it's not very well documented but that's what you'd want to use. Please feel free to get back to us with specific usage questions. -- Dr. Bobby R. Bruce Room 2235, Kemper Hall, UC Davis Davis, CA, 95616 web: https://www.bobbybruce.net On

Yes, the gem5-resources was wrong, but I think this commit fixes the issues here? https://gem5-review.googlesource.com/c/public/gem5-resources/+/33555 It has just been merged, so if you pull the latest version I think this should compile. -- Dr. Bobby R. Bruce Room 2235, Kemper Hall, UC Davis

[gem5-users] gem5 v20.0.0.3 Hotfix Release

Dear all, On July 1st we were made aware of a bug within gem5-20.0, reported by Hsuan Hsu here: https://gem5.atlassian.net/browse/GEM5-658. The bug resulted in gem5 crashing when calling m5ops, using the ARM ISA. Thankfully the source of this bug was found and fixed (here:

[gem5-users] Re: Address incrementing by 8 instead of 4 for int when SimpleMemory is configured as SPM

Is the problem you are facing in the gem5 code or your guest-code running in the simulation? This looks to be a problem in the guest-code. You're calling pointer++ twice, which should, naturally, increment the address by 8. Based on this information, I do not know why the first incrementation

[gem5-users] [Suggestion] Replace gem5-users mailing-list with Discourse

Dear all, In an effort to better support the gem5 community, there has been a suggestion that we drop the gem5-users mailing list and replace it with Discourse, https://www.discourse.org/about, a web-based discussion platform. I'm writing this email to propose this to the community and ask for

[gem5-users] Re: How Increase ROI time at gem5?

Furat, It's been several years since I've played with the PARSEC suite, but some applications can be run (or built?) in a way that increases or decreases their execution time. I know, for example, bodytrack can be tweaked to be slower or faster given depending on how accurate you want your
