You have been subscribed to a public bug: [IMPACT] * kexec-tools in Xenial (16.04) currently does not support ARM64 architecture. * Backport support for ARM64 arch from upstream https://github.com/horms/kexec-tools * Majority of the patches are contained in kexec/arch/arm64/ except for one patch that impacts purgatory and common device tree routines.
[TEST CASE] * I built kexec-tools for ARM64 and tested it on HW using the following testcase: $ sudo kexec -l /boot/vmlinuz-<version>-generic --initrd=/boot/initrd.img-<version>-generic --command-line="root=UUID=<uuid> ro vt.handoff=7" $ sudo kexec -e * I was able to kexec the new kernel successfully. * [ 6702.357899] kexec_core: Starting new kernel [ 0.000000] Booting Linux on physical CPU 0x200 [ 0.000000] Linux version <version>-generic (buildd@bos01-arm64-008) (gcc version 5.4.0 20160609 (Ubuntu/Linaro 5.4.0-6ubuntu1~16.04.4) ) [ 0.000000] Boot CPU: AArch64 Processor [510f8000] [REGRESSION POTENTIAL] * Since patches are confined to arm[64] there is a low overall risk of regression. [OTHER INFO] * You can find a Xenial kexec-tools package built for AMD64, i386 and ARM64 in my PPA https://launchpad.net/~manjo/+archive/ubuntu/devtools/ * This package is built using the Xenial source package for kexec-tools with ARM64 enablement patches applied. * Please pull the changes from my PPA package and integrate into Ubuntu Xenial kexec-tools after review. ** Affects: kexec-tools (Ubuntu) Importance: High Assignee: Louis Bouchard (louis-bouchard) Status: New -- [SRU] [Xenial] Enable ARM64 support in kexec-tools https://bugs.launchpad.net/bugs/1659618 You received this bug notification because you are a member of Kernel Packages, which is subscribed to kexec-tools in Ubuntu. -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
