In the dm163-test and stm32l4x5_usart-test, a couple of subtests are missing the qtest_quit() call. The effect of this is that on hosts other than Linux and FreeBSD the test will timeout after executing all the tests: 242/845 qemu:qtest+qtest-arm / qtest-arm/dm163-test TIMEOUT 60.04s 3 subtests passed 100/845 qemu:qtest+qtest-arm / qtest-arm/stm32l4x5_usart-test TIMEOUT 600.02s 5 subtests passed This happens because the qemu-system-arm binary which the test starts does not exit, and because it shares the stdout with the test binary, the overall meson test harness thinks the test is still running. On Linux and FreeBSD we have an extra safety net set up in qtest_spawn_qemu() which kills off any QEMU binary that ends up without a parent. This is intended for the case where QEMU crashed and didn't respond to a SIGTERM or polite request to quit, but it also sidestepped the problem in this case. However, OpenBSD doesn't have a PDEATHSIG equivalent, so we see the timeouts when running a 'make vm-build-openbsd' run. Add the missing qtest_quit() calls. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> --- Many thanks to Dan Berrangé for diagnosing the cause of this hang... Dan also suggested on IRC that we should support g_autoptr for the QTestState, so you don't need to manually qtest_quit(). But for the immediate fix, I just add the missing calls. --- tests/qtest/dm163-test.c | 2 ++ tests/qtest/stm32l4x5_usart-test.c | 2 ++ 2 files changed, 4 insertions(+)
