That version of gem5 is a few years old and doesn't have the updates to the
m5 utility that made it use scons. In that version, you need to use make.

Hi all,
I am trying to compile m5 utils. I followed the documentation available at

I am using

In the above repo, utils/m5 directory has no scons file and I
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
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 (
Hey Mahyar,
I think I didn’t describe my problem correctly. I want to send one packet per
cycle over the XBar (for 4B/cycle, for example), however, I am only managing to
send one packet every two cycles (2B/cycle). It seems like the
pkt->payloadDelay is getting set to include the time to
You have to use:
ThreadID tid = [...]
ThreadContext * tc = cpu->getContext(tid)
ContextID = tc->contextId();

Got it, thanks. If I have a ThreadID and know what CPU it's running on, how
would I go about retrieving the corresponding ContextID?

Hi Farhad,
To clarify:
* CPU ports, in all simple, minor and O3 configurations, tag generated
Requests with ContextID.
* Outgoing Packets from CPU ports have a Request pointer inside, via which
you can get the ContextID.
Kind regards,
Adrian.

Hi Tracy,
I think you can put scheduleInstStop() and m5.simulate() in a loop to do that.

HI Farhad,
ThreadID -> index of the thread within the CPU
ContextID -> global index of the thread within the System
As you can imagine they differ in a MP simulation, with multiple CPUs per System

Hey,
I've tried my hand at this problem before and it can be a bit tricky but
with patience and some python scripts you can get what you want.
First, depending on what memory address you are interested in, you will
probably need to extract the physical address. Or if you can just pick an
address
Hi,
I assume that you want to keep track of a piece of data at a specific
virtual/physical address. I don't know a definite answer to this, but
one thing you can do is to use the gem5 logging system (i.e. DPRINTF
and the like) and figure out what flags you should enable to keep
track of

Can you please confirm that this change,

Hi Duc Anh,
To answer the question about simulation speed, I believe the
difference between SE mode and FS mode is minimal. In addition to
that, kernel interactions, like process scheduler and page table
walks, have significant impact on system performance, so in most
cases, I believe it is more
