[AMD Public Use]
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.

Thanks!
I tried the develop branch. But running into new problems
warn: ignoring syscall set_robust_list(...)
warn: ignoring syscall rt_sigaction(...)
(further warnings will be suppressed)
warn: ignoring syscall rt_sigprocmask(...)
(further warnings will be suppressed)
warn: ignoring syscall mprotect(...)
warn: ignoring syscall mprotect(...)
fatal: syscall getdents (#78) unimplemented.

And I think the dockerfile needs some update. The scons requires python3.6 to
compile gem5, to be specific, `python3-config` need python3.6, but the default
version installed with the docker is 3.5.
Best, Yichen

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.

[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<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.gem5.org%2Fdocumentation%2Fgeneral_docs%2Fgpu_models%2FGCN3&data=04%7C01%7CMatthew.Poremba%40amd.com%7C980fe8dd09644c3cc28008d8829b271d%7C3dd8961fe4884e608e11a82d994e183d%7C0%7C0%7C637402950178924915%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=ZpmiYAeHJQWW2Q223UJnRuiA4DuBlgTf%2BGYMMh2p3AY%3D&reserved=0>.
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:
