[gem5-users] Reading the size of X86 register
Hi, Is there a way to access the data size of operand/destination register of some instruction? For example, in mediaOpReg, there are uint8_t srcSize, as well as uint8_t destSize but I believe these information don't get passed to the super class, i.e. StaticInst, when it get constructed. Therefore I couldn't access these info through staticInstPtr. Thanks ___ gem5-users mailing list gem5-users@gem5.org http://m5sim.org/cgi-bin/mailman/listinfo/gem5-users
Re: [gem5-users] Compilation error
Hi Ciro,
It is solved already. I found out the problem resides in one of the header
files I added in .
I use the latest gem5 version, on ubuntu 16.04.
Thanks!

Re: [gem5-users] Compilation error
Hi Oscar,
I think it is because of in one of the header files I had the issue as you
described. It is solved already. Thanks!

[gem5-users] Multi-core execution - gem5 & big.LITTLE total cores
Dear all, I wonder if It is possible to run the gem5 on a multi-core mode(like the scons build/ARM/gem5.opt -j “n”) in order to reduce the simulation time. In addition, what is the difference between armv8_gem5_v1_big_little_2_2.dtb and armv8_gem5_v1_big_little_2_4.dtb? I ask because I want to simulate a 8 core big.LITTLE system of 4 big cores and 4 little cores and I don’t know which is a suitable .dtb file.

Re: [gem5-users] Compilation error
Hi,
Most (if not all) of the errors are just a consequence of the first one
so they don't really matter. Most probably, you're missing a ";"
somewhere before the "namespace py = pybind11;" line.

Oscar

Re: [gem5-users] Error in running Moby(Asimbench) benchmark in gem5
I found what is the problem.
The cause is not a dtb file. It is --mem-size.
You need to specify the unit of the capacity (MB or GB). As I think, it is
due to the lack of memory size.

I have followed the instructions provided in the gem5.org website to
run the Moby benchmarks on gem5 as follows:
1. Downloaded the Asimbench from https://bitbucket.org/yongbing
_huang/asimbench/downloads/ which contains the following folders and
files:
1. asimbench_android_arm_kernel
Re: [gem5-users] Error in running Moby(Asimbench) benchmark in gem5
Dear Mitali Sinha.
Sorry for late reply.
Try it without specified dtb file in command line.
Actually, I run moby by myself again before writing the reply.
./build/ARM/gem5.opt configs/example/fs.py --machine-type=RealViewPBX
--os-type=android-ics
--kernel=/dist/m5/system/binaries/vmlinux.smp.ics.arm.asimbench.2.6.35
--disk-image=/dist/m5/system/disks/ARMv7a-ICS-Android.SMP.Asimbench-v3.img
--mem-size=256MB --script=/dist/m5/system/boot/adobe.rcS --frame-capture
Although it is still booted up, there is no problem.
Best Regards,
Haeyoon Cho.

Re: [gem5-users] Compilation error
Does it happen on a full clean build? What is your gem5 git revision?
What is your OS? What is your compiler version? :-)
