Thanks Kyle!  Another good reason for us to get the GCN3 tests up and
running as part of kokoro soon :)

Hi Daniel,

I tried with your building command and at least it is working fine for me.

Hi Matt,


I also see the getdents error with square building gem5 with gcc 7.5.0.

I would hope we wouldn't have to define a variable in scons to get a syscall to 
work. I am not sure where is SYS_getdents / SYS_getdents64 are supposed to be 
defined, but it is not anywhere in gem5. Different compiler maybe? The change 
that broke this for me literally just moves files around so I have no ideas how 
that caused it to break.

Hi Yichen,


Based on the changes I see you've made, it seems like you are using an older

Keep in mind GCN3 was not officially part of the gem5 20.1 release, so the most

Hi,

I was trying to run gem5 with its GCN3 GPU model following the instructions on

I fixed some bugs in the code but still cannot run the example. I attached

Is there anything I did incorrectly?

 Looking into that syscall error now.



 I’m not quite sure yet how to fix the docker image since python 3.5 is
 the latest version available for the distro needed.  For now I disabled the
 check for 3.6 since it seems unnecessarily strict and doesn’t break
 anything related to this build.

 Hi Yichen,





 Based on the changes I see you’ve made, it seems like you are using an
 older version of gem5.  These should all be fixed, including the error you
 are seeing, on the tip of develop.



 Keep in mind GCN3 was not officially part of the gem5 20.1 release, so
 the most up to date version is on the develop branch until the next gem5
 release.

 Is there anything I did incorrectly?

 To be specific, I use the following command:

I'm using the gcn3 docker, so Ubuntu 16.04 I believe

Hi Daniel & Yichen,

What OS are you using?  We have not encountered either of these problems
thus far ... something must be different about your setup and ours.

[gem5-users] Re: gem5 GCN3 GPU model running issues

[Daniel Gerzhoy via gem5-users]

For some reason that syscall is only built if you set a flag. Recompile the
simulator like so:

scons -j$(nproc) build/GCN3_X86/gem5.opt --ignore-style SLICC_HTML=True
CCFLAGS_EXTRA="-DSYS_getdents -DSYS_getdents64"

Cheers,

Dan

Looking into that syscall error now.

I'm not quite sure yet how to fix the docker image since python 3.5 is the 
latest version available for the distro needed.  For now I disabled the check 
for 3.6 since it seems unnecessarily strict and doesn't break anything related 
to this build.

Hi Yichen,


Based on the changes I see you've made, it seems like you are using an older 
version of gem5.  These should all be fixed, including the error you are 
seeing, on the tip of develop.

Keep in mind GCN3 was not officially part of the gem5 20.1 release, so the most 
up to date version is on the develop branch until the next gem5 release.

Hi,

I was trying to run gem5 with its GCN3 GPU model following the instructions on 
https://www.gem5.org/documentation/general_docs/gpu_models/GCN3.

I fixed some bugs in the code but still cannot run the example. I attached 
commands and bugs I fixed below.

The simulator launched and running into this problem:
Program Started!

Is there anything I did incorrectly?

To be specific, I use the following command:
## build docker
docker build -t gcn3-test gem5/util/dockerfiles/gcn-gpu
## make gem5

Hi Yichen,


Based on the changes I see you've made, it seems like you are using an older 
version of gem5.  These should all be fixed, including the error you are 
seeing, on the tip of develop.

Keep in mind GCN3 was not officially part of the gem5 20.1 release, so the most 
up to date version is on the develop branch until the next gem5 release.

Subject: [gem5-users] gem5 GCN3 GPU model running issues

[CAUTION: External Email]
Hi,

I was trying to run gem5 with its GCN3 GPU model following the instructions on 
https://www.gem5.org/documentation/general_docs/gpu_models/GCN3.

I fixed some bugs in the code but still cannot run the example. I attached 
commands and bugs I fixed below.

The simulator launched and running into this problem:
Program Started!
info: running on device
info: architecture on AMD GPU device is: 801
info: allocate host mem (  7.63 MB)
info: launch 'vector_square' kernel
panic: panic condition availableTokens > maxTokens occurred: More tokens 
available than the maximum after recvTokens!
Memory Usage: 1737788 KBytes
Program aborted at tick 137231963000

Is there anything I did incorrectly?

Thanks!
Best, Yichen

To be specific, I use the following command:
## build docker
docker build -t gcn3-test gem5/util/dockerfiles/gcn-gpu
## make gem5
docker run --rm -v $PWD/gem5:/gem5 -w /gem5 gcn3-test scons -sQ -j$(nproc) 
build/GCN3_X86/gem5.opt
## make application
docker run --rm -v $PWD/gem5-resources:/gem5-resources -w /gem5-resources -u 
$UID:$GID \

gcr.io/gem5-test/gcn-gpu
 make gfx8-apu -C /gem5-resources/src/square
## run gem5
docker run --rm -v $PWD/gem5:/gem5 -v $PWD/gem5-resources:/gem5-resources \
-w /gem5 gcn3-test \
build/GCN3_X86/gem5.opt configs/example/apu_se.py -n2 \
--benchmark-root=/gem5-resources/src/square/bin \
-c square.o

And here's the bugs I fixed:
