[gem5-users] Re: How to use Gem5?

[Anamika via gem5-users]

Hi,

I want to compute the power consumption of the processor, while encoding
data. (power consumed by an specific application like encoder/decoder)

I have python script for the encoder. (Creating the SimObject is yet a task
for me, I am going through the video available on YouTube for creating
theSimObject.)

The stats and output are stored in m5out stats.txt file.
But I don't know how power will be computed.
What should be the command I should give to run my script?

Kindly help.
Thank you...

[gem5-users] Support for ARM MPAM and RISC-V CBQRI in GEM5!

[Amir Kh via gem5-users]

Hello everyone,

I'm looking for information regarding the availability of support for ARM MPAM 
and RISC-V CBQRI in GEM5. If anyone has any knowledge about these features or 
can provide assistance, I would greatly appreciate it. Thank you in advance for 
your help.

Best regards,

Amir

[gem5-users] Entropy Pool and getrandom - X86 FS Simulation

[Abdelrahman S. Hussein via gem5-users]

Hello,

I am trying to run Cassandra benchmark from the Dacapo benchmark suite. I
am using gem5 v23.0.1 and the simulation is full system X86 ISA.

During the initialization phase of the Cassandra benchmark during the
simulation on gem5, I encountered this error:
```shell
: getrandom indicates that the entropy pool has not been
initialized. Rather than continue with poor entropy, this process will
block until entropy is available.
```

So, I would like to inquire if the entropy pool is supported in gem5 by
default or if there is something I need to do/implement. I am basically
restoring the checkpoint using AtomicSimpleCPU after booting to run the
initialize the workload (i.e., Cassandra) but it gave me this error (or
warning, not sure).

So, would you please help me with that?

Thanks,
~Abdelrahman
