24.22.4.8. gem5 event queue DerivO3CPU syscall emulation freestanding example analysis
Like gem5 event queue MinorCPU syscall emulation freestanding example analysis but even more complex since for the gem5 DerivO3CPU!
The key new debug flag is O3CPUAll:
./run \ --arch aarch64 \ --emulator gem5 \ --userland userland/arch/aarch64/freestanding/linux/hello.S \ --trace FmtFlag,Cache,Event,ExecAll,O3CPUAll \ --trace-stdout \ -- \ --cpu-type DerivO3CPU \ --caches \ ;
The output is huge and contains about 7 thousand lines!!!
