Hi
I have been looking at the mmu source code in gem5, and I am curious about how
gem5 handles page table fault. It seems that instruction will be labled Fault
everytime a TLB miss happens in both SE and FullSystem mode, but I could not
see how that page fault is dealt with afterwards. So my
It sounds as though trace-based debug flags in the mem_ctrl could be used
to print whatever data you are looking for to an output file:

You can view the data and data size by calling

Hey David,
Sorry about the trouble you're running into. It seems the gem5art tutorial
on the website has become a bit outdated. We've updated gem5-resources in
the last release and clearly this has broken some links. I'll make sure
updating this is prioritized.
I have two ways you can run NPB.
gem5-X is a fork of gem5, which as far as I can tell, diverged from gem5 in
the middle of 2018. gem5art was built on a version of gem5 in 2020-2021.
While I can't say anything for certain, I wouldn't be surprised if you run
into some difficulties getting this all to work perfectly.
Are you going

Hi Bobby,
I’m trying to modify my gem5-X setup to add the NPB performance tests.
My gem5-X setup doesn’t have a configs/example/gem5_library.
I believe the github repo for the gem5-X build didn’t add the gem5_library
directory and files.
I could use the gem5 setup from the NPB but then I’ll

appreciated!

Dear. Gem5 users.
I want to dump write accesses to main memory.
Especially, I need write pattern, address and size.
I tried this by to use insert a CommMonitor between bus and mem_ctrl.
However, it could dump only address and size not data.
Is there a good way to do this?
Now I work with se.py
