How to make gem5-gpu support another ISA apart from x86?

[qyang51 qyang51]

Hi, everyone, I'm new to gem5 and gem5-gpu.

I'm wondering what I should do to make gem5-gpu support another ISA apart from x86. I went through the code in gpu-compute. In gpu-compute, it seems that codes related to tlb use variables or classes in x86, like X86ISA::PageBytes or X86ISA::GpuTLB.

Thanks for any help.
