Hello!
I guess i was not clear enough in my question last time as i din't
receive any response so here i am.
1) I want to modify gem5 so that it can identify shared region among the
processes.
2) I found that arch/x86 may support system calls like shmget, shmctl etc.
but currently those system calls are not implemented.
But,
I am working with alpha "(SE mode)" so is there any way that i can modify
gem5
i) To support the system calls mentioned above.
ii) or may be use other IPC methods like message passing or others.
Thank you.
Vishal
