Hi, I got this error message. The host architecture is aarch64 and the OS is fedora36. Any idea?

===========

./build/server/instrew /bin/ls -l unhandled syscall 167 (17 20 0 400050d51f50 400050d52340 400050cffd00) = -ENOSYS -- please file a bug with these numbers and the architecture unhandled syscall 43 (400050d20428 400050cffc50 400050d40060 0 400050d067f0 400050cffd00) = -ENOSYS -- please file a bug with these numbers and the architecture unhandled syscall 98 (400050f218cc 81 7fffffff 0 4 0) = -ENOSYS -- please file a bug with these numbers and the architecture The futex facility returned an unexpected error code.

Hi, when I benchmark Instrew with SPEC CPU 2017 on aarch64, I also encountered these problems. I emailed the developer months ago and he replied

"That indicates that the program wants to use a syscall where the emulation isn't implemented yet. I changed Instrew to just warn instead of aborting execution."

Hopes this help!

Me too. I want to run x86_64 spec2006 on host aarch64. Result shows that syscall named fork, clone in emulate_syscall() do not be supportted. Without these syscall , the author how to run spec2017.

Is there qemu system mode support for instrew? Seems instrew only support user mode?

Seems instrew only support user mode?

Yes.
