[gem5-users] Issue with running a program compiled HCC on GCN3

[Sungkeun Kim]

Hi everyone,

I am trying to run a program compiled with HCC on top of GCN3, but I have
an issue regarding unimplemented system call "sched_setaffinity". Based on
my knowledge, this system call is call by one of the libraries that are
combined to the application during the compilation time. Strange thing is
that GCN3_X83 had been implemented "sched_setaffinity" system call but ROCM
library tries to use it. Could anyone help how to solve this case?
Following are my environment and romc/application/config/gem5 information
