* chardev: do not use short form boolean options in non-QemuOpts character ↵Paolo Bonzini2021-02-251-4/+4
| | | | | | | | | | device descriptions 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 <pbonzini@redhat.com>
* gdbstub: implement a softmmu based testAlex Bennée2021-01-181-9/+27
| | | | | | | | | | | | | | | | | 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 <alex.bennee@linaro.org> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Message-Id: <20210108224256.2321-6-alex.bennee@linaro.org>

* tests/tcg: better trap gdb failuresAlex Bennée2020-05-061-1/+18
| | | | | | | | | | | | | 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 runnerAlex Bennée2020-03-171-0/+57
| | | | | | | | | | | 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.

* tests/guest-debug: introduce basic gdbstub testsAlex Bennée2015-12-171-0/+176
The aim of these tests is to combine with an appropriate kernel image (with symbol-file vmlinux) and check it behaves as it should. Given a kernel it checks: - single step - software breakpoint - hardware breakpoint - access, read and write watchpoints On success it returns 0 to the calling process. I've not plumbed this into the "make check" logic though as we need a solution for providing non-host binaries to the tests. However the test is structured to work with pretty much any Linux kernel image as it uses the basic kernel_init code which is common across architectures.
