11.7.5.1. gem5 syscall emulation --smt
gem5 b1623cb2087873f64197e503ab8894b5e4d4c7b4 syscall emulation has an --smt option presumably for Hardware threads but it has been neglected forever it seems: https://github.com/cirosantilli/linux-kernel-module-cheat/issues/104
If we start from the manually hacked working command from gem5 syscall emulation multiple executables and try to add:
--cpu 1 --cpu-type Derivo3CPU --caches
We choose DerivO3CPU because of the se.py assert:
example/se.py:115: assert(options.cpu_type == "DerivO3CPU")
But then that fails with:
gem5.opt: /path/to/linux-kernel-module-cheat/out/gem5/master3/build/ARM/cpu/o3/cpu.cc:205: FullO3CPU<Impl>::FullO3CPU(DerivO3CPUParams*) [with Impl = O3CPUImpl]: Assertion `params->numPhysVecPredRegs >= numThreads * TheISA::NumVecPredRegs' failed. Program aborted at tick 0
