This script utilizes the X86DemoBoard to run a simple Ubunutu boot. The script
|
|
will boot the the OS to login before exiting the simulation.
|
|
|
|
A detailed terminal output can be found in `m5out/system.pc.com_1.device`.
|
|
|
|
**Warning:** The X86DemoBoard uses the Timing CPU. The boot may take
|
|
considerable time to complete execution.
|
|
`configs/example/gem5_library/x86-ubuntu-run-with-kvm.py` can be referenced as
|
|
an example of booting Ubuntu with a KVM CPU.
