selftests/liveupdate: Move luo_test_utils.* into a reusable libraryMove luo_test_utils.[ch] into a lib/ directory and make libliveupdatelibrary. Pull the rules to build them out into a separatelibliveupdate.mk script. This will enable these utilities to bealso built by and used within other selftests (such as VFIO).Update path in vmtest.sh as that one uses hardcoded path for util.No functional change intended.Co-developed-by: David Matlack Signed-off-by: David Matlack Acked-by: Pratyush Yadav (Google) Reviewed-by: Pasha Tatashin Signed-off-by: Vipin Sharma Link: https://patch.msgid.link/20260720203202.1964557-3-vipinsh@google.comSigned-off-by: Mike Rapoport (Microsoft) List of files: /linux/tools/testing/selftests/liveupdate/vmtest.sh

Fri, 26 Jun 2026 11:15:36 +0200

selftests/liveupdate: add end to end test infrastructure and scriptsAdd the end to end testing infrastructure required to verify theliveupdate feature. This includes a custom init process, a testorchestration script, and a batch runner.The framework consists of:init.c:A lightweight init process that manages the kexec lifecycle.It mounts necessary filesystems, determines the current executionstage (1 or 2) via the kernel command line, and handles thekexec_file_load() sequence to transition between kernels.vmtest.sh:The primary KTAP-compliant test driver. It handles:- Kernel configuration merging and building.- Cross-compilation detection for x86_64 and arm64.- Generation of the initrd containing the test binary and init.- QEMU execution with automatic accelerator detection (KVM, HVF, or TCG).run-vmtests.sh:A wrapper that runs vmtest.sh for each LUO test across supportedarchitectures, providing a summary of pass/fail/skip results.Signed-off-by: Pasha Tatashin Co-developed-by: Jordan Richards Signed-off-by: Jordan Richards Co-developed-by: Mike Rapoport (Microsoft) Acked-by: Pratyush Yadav Link: https://patch.msgid.link/20260626-luo-vmtest-v0-v4-1-e7d3111cd5b3@kernel.orgSigned-off-by: Mike Rapoport (Microsoft) List of files: /linux/tools/testing/selftests/liveupdate/vmtest.sh
