[gem5-users] Running ARM bigLittle.py in FS

[Diamantis Patsidis via gem5-users]

Hello,

I am new to gem5 and just following the official tutorial at
https://www.gem5.org/documentation/learning_gem5/part1/extending_configs .

The tutorial mentions to run bigLittle in FS mode with:

./build/ARM/gem5.opt configs/example/arm/fs_bigLITTLE.py \
    --caches \
    --bootloader="$IMG_ROOT/binaries/<bootloader-name>" \
    --kernel="$IMG_ROOT/binaries/<kernel-name>" \
    --disk="$IMG_ROOT/disks/<disk-image-name>" \
    --bootscript=path/to/bootscript.rcS

but doesn't mention which bootscript to use.

When running it without a bootscript file:

./build/ARM/gem5.opt configs/example/arm/fs_bigLITTLE.py --caches \
--bootloader fs_images/aarch-system-20220707/binaries/boot.arm \
--kernel fs_images/aarch-system-20220707/binaries/vmlinux.arm \
--disk fs_images/aarch-system-20220707/disks/m5_exit.squashfs.arm

I get the error message:

AttributeError: Class HPI_BP has no parameter 'BTBEntries'

If you have any insights about it, I would be thankful.
