[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/kexec-tools * 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.
