kvm-unit-tests is designed to be run with QEMU as the virtual machine monitor. It relies on devices emulated by QEMU (like isa-debug-exit or testdev) and it makes certain assumptions based on the implicit QEMU virtual environment configuration (like the serial base address). kvmtool [1] is a lightweight virtual machine monitor for running KVM guests. kvmtool has reduced complexity compared to QEMU and is easily hackable. This patch series aims to make it possible to run kvm-unit-tests using kvmtool on the arm and arm64 architectures, with one caveat: when terminating a test, the userspace process won't exit with an exit code that signals the success or failure of the test. Output from the test can still be parsed to determine the outcome of the test. * Patches 1 and 2 add support for discovering the ns16550a UART emulated by kvmtool on arm and arm64. * Patches 3,4 and 5 provide an alternative mechanism for terminating the virtual machine by using PSCI. * Patches 6 and 7 remove an error when parsing the test parameters generated by kvmtool.
