Hi Gabriel:
1. I change the file name from SConscript to hello (deregister
simple_memobj), it could compile successfully.

2.I used the downloaded SConscript from the website. I'll show the content
below.

It looks like you are not using the latest version of the tutorial source code.
Where did you get the tutorial source code from?
I would recommend checking out the tag v21.0.0.0 and starting from the code in
src/learning_gem5/part2.
gem5 API has recently changed and any file older than a couple o
OK I’ll check it out. I got these code from gem5 book.
By the way, could you give me the link for the latest tutorial guide and
code so that I can follow them?(gem5 book’s code seems outdated)
Thanks for the assistance!

Hi Abhijeeth,
With regards to your first message, it looks like you are using a custom
configuration python script. Often times these errors occur from failing to
import the objects in the same way based on the directory. For example, if
you look at the script "configs/example/se.py" you'll see th
Hi Wang,
If by "write buffer queue", you mean the "mandatoryQueue", then you cannot
restrict its size wihtout risking an assert error as the sequencer does not
check the mandatoryQueue fullness before enqueuing.
Still, the maximum number of concurrent tag array and data array lookups can be

If you follow each step carefully starting from here, you should be good ;) The
tutorial has been updated recently to take the latest API changes into account.

Hello
I am trying to model a system such as
1) Initially there are two clusters, [big, little]
a. Have studied fs_bigLITTLE.py to see how the different clusters are
generated.
2) Make use of CHI
3) Run the system in SE mode.
The command I am planning to use is the following
Hi Javed,
I don't think that you want to use devices.CpuCluster as it is used to manage
classic caches while you want to use Ruby caches.
My first approach would be, using se.py as is:
1- Define two more options in CHI.py to specify the number of big (B) and
the number of little (L) cpus fr
Many thanks for the pointers, Gabriel.
Best Regards

Hi Sam,
No, there's not good documentation on this (yet ;)). It's relatively easy
to set up, though. Instead of using a single packet ptr, you can have a
queue (or whatever datastructure you would like), and you can set the
blocked flag only when it is "full" (e.g., the number of items in the

Hi Deepak,
Have you tried the latest gem5? There's been a lot of work in both
gem5-21.0 and on gem5-develop to improve the RISC-V FS support. Another
option would be to look at how the RISC-V code has changed to see if that
helps diagnose this problem.
Cheers,
Jason

Hi Deepak,
Yeah, the cache disable bit may not work correctly in the page table
walker/TLB. You can check the code there to see if that's what's going
wrong.
You can also try adding an E820 entry to the workload object (e.g.,

Hi Pedro,
No, I don't think there's an easy way to run m5_write_file on the guest
from the host. That is an instruction that is executed on the guest, and
the host can't easily control what is executing on the guest (especially
when you consider that it has to execute in the right context, etc.).
Hi Xijing,
You can set specific mappings from virtual to physical addresses by calling
the `map()` function on the Process object from your python configuration
file. See
https://gem5.googlesource.com/public/gem5/+/refs/heads/stable/src/sim/Process.py#37
Then, once you have a virtual->physical ma
Hi Sam,
Are the (virtual, physical?) addresses different when you use the larger
arrays? I wonder if the underlying mmap or malloc calls are breaking in SE
mode somehow. Maybe, after you allocate in your guest code you can print
out the virtual address to make sure it looks reasonable. You can als
Hi,
Could anybody help me understand what happens in gem5 when a read request
reaches a cache (say L3) and L2's write queue has a pending writeback
(writeback that has not yet been written to L3) with the same block as the
read request? Is the read request gets serviced from the write queue as

Hello,
I am using SE mode in gem5 and trying to implement the concept of processing in

to make it takeover all the contents of the host processor to be operated in
the memory instead of the host CPU.

Hi everyone,
I am trying to use HMC in SE mode. The problem is when I run hello world binary
