Hi all, I'm building and running gem5 using the guest binary Ubuntu 18.04 image for ARM64 linked from the gem5 guest binaries page (https://www.gem5.org/documentation/general_docs/fullsystem/guest_binaries). However, when running the system in full system for ARM bigLITTLE
``` gem5-workspace/gem5/build/ARM/base-gem5.opt gem5-workspace/gem5/configs/example/arm/fs_bigLITTLE.py --kernel gem5-workspace/gem5/dist/binaries/vmlinux.arm64 --cpu-type atomic --dtb gem5-workspace/gem5/system/arm/dt/armv8_gem5_v1_big_little_2_2.dtb --disk gem5-workspace/gem5/dist/disks/ubuntu-18.04-arm64-docker.img --bootscript gem5-workspace/gem5/bootscripts/test.rcS ``` I get the following error ``` [ 3.915428] Kernel panic - not syncing: Requested init /sbin/init failed (error -2). [ 3.915434] CPU: 0 PID: 1 Comm: swapper/0 Not tainted 4.18.0+ #1 [ 3.915439] Hardware name: V2P-AARCH64 (DT) [ 3.915442] Call trace: [ 3.915447] dump_backtrace+0x0/0x1c0 [ 3.915453] show_stack+0x14/0x20 [ 3.915458] dump_stack+0x8c/0xac [ 3.915462] panic+0x130/0x288 [ 3.915467] kernel_init+0xa8/0x108 [ 3.915472] ret_from_fork+0x10/0x18 [ 3.915477] Kernel Offset: disabled [ 3.915481] CPU features: 0x21c06492 [ 3.915485] Memory Limit: 2048 MB [ 3.915492] ---[ end Kernel panic - not syncing: Requested init /sbin/init failed (error -2). ]--- ``` And a kernel panic in the host terminal process. I mounted the Ubuntu 18.04 disk image into a temporary directory to examine the contents of the /sbin/ directory to confirm that there wasn't an init file there (which there was not). My next step was to look at the /sbin/ directory of an Ubuntu 18.04 virtual machine to see if perhaps there was a different kernel init file being used under this version of Ubuntu (I also have the "aarch64-ubuntu-trusty-headless.img" downloaded from gem5 guest binaries, and there is a file /sbin/init in that image) so that I could just change where gem5 looks for this binary, but - based on the VM - it seems as though this file structure hasn't changed. Is this an issue with gem5's released version of Ubuntu 18.04 for ARM? And if so, is there either (a) an alternative image file for Ubuntu 18.04 for ARM with the appropriate kernel initialization files or (b) a place where those files exist where I can install them onto the current Ubuntu 18.04 image? Thank you for your help!
