I found this article that suggests Ubuntu 19.10 specifically enabled this flag for the first time by default: https://www.phoronix.com/scan.php?page=news_item&px=Ubuntu-19.10-GCC-Hardening. I guess th

Thanks Steve, I can confirm that I see the problem too using Ubuntu 19.10 (gcc 9.2.1). Ubuntu 19.04 compiles ACRN correctly (uses gcc 8.3.0). I have filed an issue to track this: https://github.com/pr

We use a gcc 9.2.1 in Clear Linux to build ACRN these days, I’ll see if I can spin up an Ubuntu 19.04 machine to reproduce the failure. Geoffroy

We also have a Docker container you can use to build ACRN, if that’s any easier to you – here are the instructions on how to use it: https://projectacrn.github.io/latest/tutorials/building_acrn_in_doc

How much memory do you have installed on that system? Any additional PCI that you have installed (exotic or not) that could cause this? Geoffroy

Great – thanks for confirming this Alfonso!

Hi Fengwei,

Hi Alfonso, You are not building with CONFIG_RELEASE=y by any chance? (If the tag info below is correct, the default is not to use that). In case you did, note that it will disable the use of the seri

Your build instruction below should be fine (you can always also check the content of build/hypervisor/.config to make sure that you have CONFIG_INDUSTRY=y in it). Note though that “sudo make install”

Is there any value at all in having this maxcpus parameter *anywhere*? My thinking is that it's ACRN that determines how many vCPUs are visible to any User VM, and we'd want our User VM to always use

Hi Dubravko,

Have you observed the same problems on the UP2 board? Thanks, Geoffroy

Sounds good!

Do you already have one of the NUC listed on the "Supported Hardware" page? It's great to hear you'll be evaluating ACRN and Clear Linux, please let us know how you get on, even if you don't hit any i

We do not test it on standard laptop. The likekihood of success depends amongst other things of the processor you have on the laptop. We test ACRN on Apollo Lake and Kaby Lake processors. You also nee

Congratulations, this is an important milestone indeed!!!

Hi Thomas, Welcome to the ACRN community!! Your kernel command-line is most likely incorrect, change root=/dev/mmcblk0p1 to root=/dev/mmcblk0p3 (the first partition is typically the EFI System Partiti

Sounds good, I have filed https://github.com/projectacrn/acrn-hypervisor/issues/2830 to track this. Thanks! Geoffroy
