After investigation and help from the Qemu/KVM maintainers[2], it turns out that this is a known quirk: software that wants to run under KVM needs to take care what instructions it uses for MMIO accesses. Linux doesn't suffer from this issue, because it implements readl/writel in assembly and makes sure they use KVM-friendly instructions. I'll suggest on the OE-core mailing list that the bootloader tests should be conducted with KVM disabled. Nevertheless, running barebox under KVM alerted me to some issues that exist outside of KVM too, so I prepared a series that enables barebox to run under KVM[3]. I thought to mention that here in case someone is interested in getting U-Boot to work under KVM as well. Also feel free to backport any other barebox goodies along the way. :-) [1]: https://lore.kernel.org/all/b77f2c6737c330ef9ecce325d50a4aaa25b3e536.camel@… [2]: https://lore.kernel.org/all/89f184d6-5b61-4c77-9f3b-c0a8f6a75d60@pengutroni… [3]: https://lore.kernel.org/barebox/20241009060511.4121157-5-a.fatoum@pengutron… Cheers, Ahmad -- Pengutronix e.K. | | Steuerwalder Str. 21 | http://www.pengutronix.de/ | 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 |

[PATCH 1/4] boot: pxe_utils: Add fallback support
by Martyn Welch 09 Oct '24

09 Oct '24

When configured correctly, we can detect when boot fails after the boot process has been handed over to the kernel through the use of U-Boot's bootcount support. In some instances, such as when we are performing atomic updates via a system such as OSTree, it is desirable to provide a fallback option so that we can return to a previous (hopefully working) state. Add a "fallback" option to the supported extlinux configuration options that points to a label like "default" so that we can utilise this in later commits.
