I have my class experimenting with gem5 this semester, and one of the classes will be looking at O3CPU model. If I don't specify CPU_MODELS=O3CPU in the build process, does the gem5 program already include the O3CPU model? I noticed that I was able to use some of these models without specifying them during the build cycle. The Build-opts list does not include them. Nick

Hi Nick, All CPU models are included in all builds except when no ISAs are selected (NULL). When building gem5 with support for more than 1 ISA instead of using just "O3CPU" you have to use an ISA-specific version (e.g., ArmO3CPU). The standard library will hide some of the details from you if you specify the CPUType (e.g., O3CPU) and ISA (e.g., Arm) when constructing the SimpleProcessor. (I didn't look at the code while writing this message so I could have some of the names slightly wrong.)
