* tests/tcg: Fix run for tests with specific pluginGustavo Romero2025-08-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Commit 25aaf0cb7f (“tests/tcg: reduce the number of plugin test combinations”) added support for running tests with specific plugins passed via the EXTRA_RUNS variable. However, due to the optimization, the rules generated as a shuffled combination of tests and plugins might not cover the rules required to run the tests with a specific plugin passed via EXTRA_RUNS. This commit fixes it by correctly generating the rules for the tests that require a specific plugin to run, which are now passed via the EXTRA_RUNS_WITH_PLUGIN instead of via the EXTRA_RUNS variable. The fix essentially excludes the tests passed via EXTRA_RUNS_WITH_PLUGIN from the rules created by the shuffled combination of tests and plugins, to avoid running the tests twice, and generates the rules for the test/plugin combinations listed in the EXTRA_RUNS_WITH_PLUGIN variable.

* tests/tcg: reduce the number of plugin tests combinationsAlex Bennée2025-07-261-4/+7
| | | | | | | | | | | | | | | | As our set of multiarch tests has grown the practice of running every plugin with every test is becoming unsustainable. If we switch to ensuring every test gets run with at least one plugin we can speed things up. Some plugins do need to be run with specific tests (for example the memory instrumentation test). We can handle this by manually adding them to EXTRA_RUNS. We also need to wrap rules in a CONFIG_PLUGIN test so we don't enable the runs when plugins are not enabled.

* tests/tcg: Do not use inttypes.h in multiarch/system/memory.cIlya Leoshkevich2024-12-241-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | make check-tcg fails on Fedora with the following error message: alpha-linux-gnu-gcc [...] qemu/tests/tcg/multiarch/system/memory.c -o memory [...] qemu/tests/tcg/multiarch/system/memory.c:17:10: fatal error: inttypes.h: No such file or directory 17 | #include <inttypes.h> | ^~~~~~~~~~~~ compilation terminated. The reason is that Fedora has cross-compilers, but no cross-glibc headers. Fix by hardcoding the format specifiers and dropping the include. An alternative fix would be to introduce a configure check for inttypes.h. But this would make it impossible to use Fedora cross-compilers for softmmu tests, which used to work so far.

* tests/tcg: add a system test to check memory instrumentationAlex Bennée2024-09-193-16/+170
| | | | | | | | | | | | | | | | | | | | | | | | | At first I thought I could compile the user-mode test for system mode however we already have a fairly comprehensive test case for system mode in "memory" so lets use that. As tracking every access will quickly build up with "print-access" we add a new mode to track groups of reads and writes to regions. Because the test_data is 16k aligned we can be sure all accesses to it are ones we can count. First we extend the test to report where the test_data region is. Then we expand the pdot() function to track the total number of reads and writes to the region. We have to add some addition pdot() calls to take into account multiple reads/writes in the test loops. Finally we add a python script to integrate the data from the plugin and the output of the test and validate they both agree on the total counts. As some boot codes clear the bss we also add a flag to add a regions worth of writes to the expected total.

| | | | | | | | | | | While the compilers will generally happily synthesise a 64 bit value for you on 32 bit systems it doesn't exercise anything on QEMU.

* tests/tcg: add an explicit gdbstub register testerAlex Bennée2023-11-081-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We already do a couple of "info registers" for specific tests but this is a more comprehensive multiarch test. It also has some output helpful for debugging the gdbstub by showing which XML features are advertised and what the underlying register numbers are. My initial motivation was to see if there are any duplicate register names exposed via the gdbstub while I was reviewing the proposed register interface for TCG plugins. Mismatches between the xml and remote-desc are reported for debugging but do not fail the test. We also skip the tests for the following arches for now until we can investigate and fix any issues: - s390x (fails to read v0l->v15l, not seen in remote-registers) - ppc64 (fails to read vs0h->vs31h, not seen in remote-registers) Cc: Akihiko Odaki <akihiko.odaki@daynix.com> Cc: Luis Machado <luis.machado@linaro.org> Cc: Ilya Leoshkevich <iii@linux.ibm.com> Cc: qemu-s390x@nongnu.org Cc: Nicholas Piggin <npiggin@gmail.com> Cc: Daniel Henrique Barboza <danielhb413@gmail.com> Cc: qemu-ppc@nongnu.org Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Message-Id: <20231106185112.2755262-7-alex.bennee@linaro.org>

| | | | | | | | | | | | | System emulation tests do not run in a hosted environment, since they do not link with libc. They should only use freestanding headers (float.h, limits.h, stdarg.h, stddef.h, stdbool.h, stdint.h, stdalign.h, stdnoreturn.h) and should be compiled with -ffreestanding in order to use the compiler implementation of those headers rather than the one in libc.
