Thank you for your reply. I put the latest version of gem5 into a directory
that is not adjacent to the old version of gem5, and compiled successfully. But
there are some warnings：*** Summary of Warnings ***

Hey Fisher,
I'm not sure if that is correct as every packet spends at least one cycle
on the XBar (even in real hardware), however, I would say one limiting
factor in gem5 about the XBar is the fact that you can't effectively
increase the width of the XBar as much as you want (you can say
Dear gem5 team,
I want to use gem5 to simulate a program to measure its execution time. My
goal is to measure the execution time as close as possible to the real
value, and that program is running in a heterogeneous platform, where other
programs on other CPUs can affect the program execution
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
Hey Mahyar,
Thanks for the response! I’m actually not seeing the 1 packet per cycle
expectation…
I think I have root-caused the issue to the timing calculation in the XBar,
however, I’m not sure if this is an intentional design choice or something else:
It calculates the time for a packet as
In the process of step-by-step debugging of gem5, how can I know whether a data
currently exists in cache or in memory, and what level of cache it is? I think
gem5 should provide such a method?
Thanks for answer.

Hi Duc Anh,
I think the stats error is related to this change,
https://gem5-review.googlesource.com/c/public/gem5/+/36296.
The stats bug should be resolved when you cherry-pick that change.
Hopefully we can add the SMT feature and fix the multicore DerivO3 bug by
the next release.

I just downloaded the latest gem5. Then compiled it using the scons build / x86
/ gem5. Opt command. But there was an error

Hi Hoa Nguyen,
A bit sad when some features I want will only be supported from 20.2
version (SMT, multicore DerivO3CPU). Do the gem5 team have any plan on when
the next version will be released?
About the stats error, I use the same version and cmd as the first email. I
will retype it here for
