Help: Running SPEC2017 on SPARC ISA in FS Mode (gem5 v20)

[navneethtj]

I'm trying to run SPEC CPU2017 benchmarks on the SPARC ISA using gem5 v20.1.0.4 in Full System (FS) mode, both for single-core and multi-core simulation. I’ve built gem5 with SPARC and can run basic binaries in SE mode, but FS mode lacks proper references. I'm struggling to find working SPARC Linux kernels and disk images compatible with gem5. Most guides are ARM/x86-specific.

Does anyone have:

1. A working SPARC FS image or kernel?
2. Steps to compile a SPARC Linux kernel for gem5?
3. Any prior work or repo using SPARC FS mode with SPEC workloads?

Any references, disk images, or example configs would help a lot. Thanks!
