From 1a8755a51eef11360af92adf71fed6a20a1260b2 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Daniel=20P=2E=20Berrang=C3=A9?= Date: Thu, 21 Nov 2024 16:57:44 +0000 Subject: tests/functional: add a QMP backdoor for debugging stalled tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Support the QEMU_TEST_QMP_BACKDOOR=backdoor.sock env variable as a way to get a QMP backdoor for debugging a stalled QEMU test. Most typically this would be used if running the tests directly: $ QEMU_TEST_QMP_BACKDOOR=backdoor.sock \ QEMU_TEST_QEMU_BINARY=./build/qemu-system-arm \ PYTHONPATH=./python \ ./tests/functional/test_arm_tuxrun.py And then, when the test stalls, in a second shell run: $ ./scripts/qmp/qmp-shell backdoor.sock Signed-off-by: Daniel P.
