[gem5-users] Re: Capturing SimPoint and running on ARM CycleModel

2024-04-15 Thread 王理治 via gem5-users 

Hi Jason,

I’m using ELFies with gem5. I have tried your example in gem5-hpca-2023 and it 
works. But I meets some trouble in generating ELFies with the Sniper simulator, 
can you provides any scripts to generate these ELFies with LoopPoint output 
csv/json files?

Thanks,
Liz Wang

Know any resources for “the anatomy of an ELFie”? Alongside the anatomy of a 
Gem5 Checkpoint. That way I can possibly write something similar to pinball2elf 
but for gem5 -> ELFie…

From the links you sent, it’s still Pin based and the resulting ELFies are x86 
right? I’d want to do this for ARM.

Hi Jonathan, We just did a tutorial on how to use ELFies with gem5. See https:

That said, we currently only support ELFies generated by the Sniper simulator. 
If you want details on how to do that, you'll have to check out the looppoint 
documentation above or contact the looppoint/ELFie authors.

It would be nice if we could generate an ELFie [1] from a gem5 checkpoint. As I

#2 would seem to be able to generate ELFies from the x86 pinballs that were 
captured. However, I’m unfamiliar with how ELFies work. Do they still capture 
state and thus need to inject processor state prior to simulation? In which 
case the problem still exists that the ARM Cycle Model is incompatible….

Thanks,

Jonathan.

it easily on Gem5 simple CPU in SE mode but I need it to work with our more 
accurate model.



You can easily generate SimPoints with gem5 as you correctly said. The problem 
is the checkpoint incompatibility between gem5 and Cycle Model. (restoring the 
gem5 checkpoint from the CA simulator).

It would be nice if we could generate an ELFie [1] from a gem5 checkpoint. As I 
have recently seen some commits mentioning ELFies you could ask Jason and his 
group if there's something going on...



Kind Regards

Hi Jonathan,

I have experience simulating SimPoint area through O3CPU in se mode.(use
the checkpoint function of gem5)
I don't know if it's only in my case, but not all Benchmarks in spec2017
had a smooth simulation process with SimPoint.
I'm still looking for a way to fix some of the workloads.

Regards,
Haseung
