Public bug reported: [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.
