[gem5-users] Using DSENT in GEM5

2023-04-17 Thread AC S via gem5-users 
Hi, I encounter a segmentation fault when  import dsent in python file
  I successfully executed make and built the target in dsent but when I
typed "import dsent" in python file (3.10 ver), it came segmentation fault
as below

Segfault happened at: 0x557878f5cc15: testb
$Ox1,0xab(%rax)PC(Ox557878f5cc15)ok
source "$ox1" ok
destination "Oxab(%rax)"(Oxo603090703aa)not located in a known vMA
region(needed writable region)!

anybody knows the reason ? could you please help me using dsent in gem5?

[gem5-users] SPEC2017 FS Simulation - Using KVM up to the point when the benchmarks finally run

2023-04-17 Thread Farbin Fayza via gem5-users 
Hello,
I'm using the x86-spec-cpu2017-benchmarks.py config file to run spec2017
benchmarks. I followed this tutorial
https://gem5.googlesource.com/public/gem5-resources/+/refs/heads/stable/src/spec-2017/
for building the spec disk image.

Currently, the linux booting is done with KVM CPU and the rest of the
simulation is done with the TIMING CPU. However, after booting linux, there
are lots of steps before the benchmark actually gets to run.

For example, here are the logs in my board.pc.com_1.device file after
booting linux:

"Welcome to Ubuntu 18.04.2 LTS (GNU/Linux 4.19.83 x86_64)

 * Documentation:  https://help.ubuntu.com

And these steps take more than a day with the TIMING CPU. Is there any way
to run everything on the KVM CPU before running the actual benchmark
application?

Thanks,
Fayza.

[gem5-users] Error: open CFI at the end of file

2023-04-17 Thread Jonathan Kang via gem5-users 
I’m trying to compile the ARM gem5 model:

# python3 /usr/bin/scons build/ARM/gem5.opt

However, I’m getting this error:
{standard input}: Assembler messages:
{standard input}:135661: Warning: end of file not at end of a line; newline 
inserted
{standard input}:135860: Error: unknown pseudo-op: `.l'

directive
g++: fatal error: Killed signal terminated program cc1plus
compilation terminated.
scons: *** [build/ARM/enums/ArmPciIntRouting.o] Error 1

Any idea what could be happening?

Normally errors like this are because you've run out of memory when
building gem5. If you're building with threads, reduce the number of
threads you're using. I normally recommend building on systems with 6GB+ to
be safe.
