[gem5-users] ARM Cortex-A57 fs quad-core

[Andreas Konopik]

Hello,

i am trying to start the ARM Cortex-A57 fs
(GEM5_SRC/configs/example/arm/starter_fs.py) with
linaro-minimal-aarch64.img. Invoking it with --num-cpu=4 displays kernel
output, but never boots until basic shell.
I tried adding "debug" to the kernel commandline, but it does not add
debugging info.
What is the easiest way to get a 4-core Cortex-A57 full system Linux
working?

Thanks in advance.

best regards,

Andreas Konopik

Please always provide gem5 command line, gem5 revision and kernel terminal
output with bug reports.

Here is a setup that just works: https://github.com/
cirosantilli/linux-kernel-module-cheat/tree/6c241279a6a1eda8accae4a4a281c4
2831a1db95#gem5-getting-started here is how to change the number of cores:

6c241279a6a1eda8accae4a4a281c42831a1db95#number-of-cores and here is an
alternate fs_biglittle.py version that allows for different CPU types:
