[gem5-users] Re: gem5 GCN3 GPU model docker build issue

[xpf via gem5-users]

Hi,

I didn't see the instructions say to use stable branch. I follow the 
instructions on http://www.gem5.org/documentation/general_docs/gpu_models/GCN3 
which don't mention to use stable or develop branch. But now I see 'integrating 
the Docker into the develop branch ' on 
https://www.gem5.org/2020/05/27/modern-gpu-applications.html.
 
Thank you very much.

[gem5-users] Re: Shutdown x86 Full System simulation

[Gabe Black via gem5-users]

Hi Deepak. On a real system, you would probably use ACPI to tell the
chipset to power down the machine, but on gem5 you can probably just run
the "exit" pseudo instruction which will tell gem5 to exit back to the
python config file.

[gem5-users] Restoring from simpoint checkpoints

[Thomas Flynn via gem5-users]

Hi,

I am trying to generate and later restore checkpoints using SimPoint, but
right now I get an error about the system's memory size when restoring from
the checkpoints.

This is the command I use to generate the checkpoint, after obtaining the
phases and weights from the SimPoint binary:

./build/ARM/gem5.opt configs/example/se.py
--take-simpoint-checkpoint=/home/tom/archsim/SimPoint.3.2/bin/simpoints,/home/tom/archsim/SimPoint.3.2/bin/weights,10,1000
--cpu-type=NonCachingSimpleCPU --cmd="se-benchmarks/Bubblesort"

The output from this looks fine:

[gem5-users] Making main memory trace files for external memory sims

[Miguel Antonio Avargues Gutiérrez via gem5-users]

Hello,

I was wondering which was the most effective way to generate main memory 
trace files to run on externals memory simulatos such as NVMain. I'm 
using the default fs.py config file with the 4.19.83 kernel and 
parsec.img as the disk image. Is maybe SE a better method to achieve this?

[gem5-users] Shutdown x86 Full System simulation

[Deepak Mohan via gem5-users]

Hi,
I was implementing an x86 operating system that runs on gem5
simulator. I have to implement the shutdown functionality for the OS.
>From my initial research I found out that I have to use the ACPI for
implementing shutdown (using outw(PM1a_CNT, SLP_TYPa | SLP_EN ); ).
But the values of PM1a_CNT, SLP_TYPa and SLP_EN has to be gathered
from the DSDT table of ACPI. When I searched the gem5 source for the
DSDT table, I was unable to find it (there was classes defined for
RSDT and XSDT tables).
Can anyone please give any pointers towards where to search ? Or are
there any other methods to shutdown the x86 Full system simulation ?

Thanks,
Deepak Mohan
