2023-08-09tests/tcg: Disable filename test for info proc mappingsRichard Henderson
This test fails when host page size != guest page size, because qemu may not be able to directly map the file. Fixes: a6341482695 ("tests/tcg: Add a test for info proc mappings") Acked-by: Ilya Leoshkevich <iii@linux.ibm.com> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

2021-11-04gdbstub: Switch to the thread receiving a signalPavel Labath
Respond with Txxthread:yyyy; instead of a plain Sxx to indicate which thread received the signal. Otherwise, the debugger will associate it with the main one. Also automatically select this thread, as that is what gdb expects.

2021-04-06tests/tcg: relax the next step precision of the gdb sha1 testAlex Bennée
Depending on the version of gdb we may not execute the first line of SHA1Init when executing the first "next" command - instead just stepping over the preamble. As we don't actually care about the position of the PC after the steps and want to be sure the context->state[] has been loaded before we inspect it do a double next at the start.

2021-01-18gdbstub: add support to Xfer:auxv:read: packetLirong Yuan
This allows gdb to access the target’s auxiliary vector, which can be helpful for telling system libraries important details about the hardware, operating system, and process.

2021-01-18gdbstub: implement a softmmu based testAlex Bennée
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>
2020-05-27tests/tcg: better detect confused gdb which can't connectAlex Bennée
While we may gamely give the right information it can still confuse the wide range of GDBs out there. For example ppc64abi32-linux-user reports: warning: Selected architecture powerpc:common is not compatible with reported target architecture powerpc:common64 warning: Architecture rejected target-supplied description but still connects. Add a test for a 0 pc and exit early if that is the case. This may actually be a bug we need to fix?

2020-05-06tests/tcg: add a multiarch linux-user gdb testAlex Bennée
When the gdbstub code was converted to the new API we missed a few snafus in the various guests. Add a simple gdb test script which can be used on all our linux-user guests to check for obvious failures.
