tests/guest-debug: better handle gdb crashes

2022-04-20T15:04:20+00:00

There are a number of GDB's on various distros which fail fairly hard when attempting to talk to a cross-arch guest. The previous attempt to catch this was incorrect as the shell will deliver signals as 128+n. Fix the detection and while we are it improve the logging we dump into the test output.

chardev: do not use short form boolean options in non-QemuOpts character device descriptions

2021-02-25T14:41:53+00:00

Options such as "-gdb" or "-serial" accept a part-QemuOpts part-parsed-by-hand character device description. Do not use short form boolean options in the QemuOpts part. Signed-off-by: Paolo Bonzini

gdbstub: implement a softmmu based test

2021-01-18T10:04:31+00:00

This adds a new tests that allows us to test softmmu only features including watchpoints. To do achieve this we need to: - add _exit: labels to the boot codes - write a memory.py test case - plumb the test case into the build system - tweak the run_test script to: - re-direct output when asked - use socket based connection for all tests - add a small pause before connection Signed-off-by: Alex Bennée Reviewed-by: Philippe Mathieu-Daudé Message-Id: <20210108224256.2321-6-alex.bennee@linaro.org>

tests/guest-debug: catch hanging guests

2020-05-15T14:25:07+00:00

If gdb never actually connected with the guest we need to catch that and clean-up after ourselves. Signed-off-by: Alex Bennée Message-Id: <20200513175134.19619-2-alex.bennee@linaro.org>

tests/guest-debug: use the unix socket for linux-user tests

tests/tcg: better trap gdb failures

2020-05-06T08:29:26+00:00

It seems older and non-multiarach aware GDBs might not fail gracefully when faced with something they don't know. For example when faced with a target XML for s390x the Ubuntu 18.04 gdb will generate an internal fault and prompt for a core dump. Work around this by invoking GDB in a more batch orientated way and then trying to filter out between test failures and gdb failures.

tests/guest-debug: add a simple test runner

2020-03-17T17:38:47+00:00

The test runners job is to start QEMU with guest debug enabled and then spawn a gdb process running a test script that exercises the functionality it wants to test.
