2021-10-20tests: qtest: add qtest_has_accel() to check if tested binary supports ↵Igor Mammedov
accelerator Currently it is not possible to create tests that have KVM as a hard requirement on a host that doesn't support KVM for tested target binary (modulo going through the trouble of compiling out the offending test case). Following scenario makes test fail when it's run on non x86 host: qemu-system-x86_64 -enable-kvm -M q35,kernel-irqchip=on -smp 1,maxcpus=288 This patch introduces qtest_has_accel() to let users check if accel is available in advance and avoid executing non run-able test-cases. It implements detection of TCG and KVM only, the rest could be added later on, when we actually start testing them in qtest.

These two are macros wrapping regular printf() call. They are intended to be used instead of calling printf() directly in order to avoid breaking TAP output format. TAP output format is enabled by using --tap command line argument. Starting with glib 2.62 it is enabled by default. Unfortunately there is currently no public glib API available to check whether TAP output format is enabled. For that reason qos_printf() simply always prepends a '#' character for now.

2021-02-16libqos/qgraph: add qos_node_create_driver_named()Christian Schoenebeck
So far the qos subsystem of the qtest framework had the limitation that only one instance of the same official QEMU (QMP) driver name could be created for qtests. That's because a) the created qos node names must always be unique, b) the node name must match the official QEMU driver name being instantiated and c) all nodes are in a global space shared by all tests. This patch removes this limitation by introducing a new function qos_node_create_driver_named() which allows test case authors to specify a node name being different from the actual associated QEMU driver name. It fills the new 'qemu_name' field of QOSGraphNode for that purpose. Adjust build_driver_cmd_line() and qos_graph_node_set_availability() to correctly deal with either accessing node name vs. node's qemu_name correctly.

2020-11-03tests/qtest/libqos/ahci.c: Avoid NULL dereference in ahci_exec()Peter Maydell
In ahci_exec() we attempt to permit the caller to pass a NULL pointer for opts_in (in which case we use a default set of options). However although we check for NULL when setting up the opts variable at the top of the function, we unconditionally dereference opts_in at the end of the function as part of freeing the opts->buffer. Switch to checking whether the final buffer is the same as the buffer we started with, instead of assuming the value we started with is always opts_in->buffer. At the moment all the callers pass a non-NULL opts argument, so we never saw any crashes in practice.

2020-11-01tests/9pfs: fix test dir for parallel testsChristian Schoenebeck
Use mkdtemp() to generate a unique directory for the 9p 'local' tests. This fixes occasional 9p test failures when running 'make check -jN' if QEMU was compiled for multiple target architectures, because the individual architecture's test suites would run in parallel and interfere with each other's data as the test directory was previously hard coded and hence the same directory was used by all of them simultaniously. This also requires a change how the test directory is created and deleted: As the test path is now randomized and virtio_9p_register_nodes() being called in a somewhat undeterministic way, that's no longer an appropriate place to create and remove the test directory. Use a constructor and destructor function for creating and removing the test directory instead. Unfortunately libqos currently does not support setup/teardown callbacks to handle this more cleanly. The constructor functions needs to be in virtio-9p-test.c, not in virtio-9p.c, because in the latter location it would cause all apps that link to libqos (i.e. entirely unrelated test suites) to create a 9pfs test directory as well, which would even break other test suites.

2020-10-19tests/9pfs: wipe local 9pfs test directoryChristian Schoenebeck
Before running the first 9pfs test case, make sure the test directory for running the 9pfs 'local' tests on is entirely empty. For that reason simply delete the test directory (if any) before (re)creating it on test suite startup. Note: The preferable precise behaviour would be the test directory only being wiped once *before* a test suite run. Right now the test directory is also wiped at the *end* of a test suite run because libqos is calling the virtio_9p_register_nodes() callback for some reason also when a test suite completed. This is suboptimal as developers cannot immediately see what files and directories the 9pfs local tests created precisely after the test suite completed. But fortunately the test directory is not wiped if some test failed. So it is probably not worth it drilling another hole into libqos for this issue.

To get the data as QObjects, it uses qmp_marshal_query_machines() and qmp_marshal_qom_list_types(). All this code is rather cumbersome. Switch to working with generated QAPI types instead: * Replace apply_to_qlist() & friends by machines_apply_to_node() and types_apply_to_node(). * Have qos_fuzz.c use qmp_query_machines() and qmp_qom_list_types() instead. * Have qos_test.c convert from QObject to the QAPI types.

2020-03-17ppc/spapr: Allow FWNMI on TCGNicholas Piggin
There should no longer be a reason to prevent TCG providing FWNMI. System Reset interrupts are generated to the guest with nmi monitor command and H_SIGNAL_SYS_RESET. Machine Checks can not be injected currently, but this could be implemented with the mce monitor cmd similarly to i386.

2020-03-17ppc/spapr: Change FWNMI namesNicholas Piggin
The option is called "FWNMI", and it involves more than just machine checks, also machine checks can be delivered without the FWNMI option, so re-name various things to reflect that.

2020-03-16misc: Replace zero-length arrays with flexible array member (automatic)Philippe Mathieu-Daudé
Description copied from Linux kernel commit from Gustavo A. R. Silva (see [3]): --v-- description start --v-- The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member [1], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being unadvertenly introduced [2] to the Linux codebase from now on. --^-- description end --^-- Do the similar housekeeping in the QEMU codebase (which uses C99 since commit 7be41675f7cb). All these instances of code were found with the help of the following Coccinelle script: @@ identifier s, m, a; type t, T; @@ struct s { ... t m; - T a[0]; + T a[]; }; @@ identifier s, m, a; type t, T; @@ struct s { ... t m; - T a[0]; + T a[]; } QEMU_PACKED; [1] https://gcc.gnu.org/onlinedocs/gcc/Zero-Length.html [2] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=76497732932f [3] https://git.kernel.org/pub/scm/linux/kernel/git/gustavoars/linux.git/commit/?id=17642a2fbd2c1 Inspired-by: Gustavo A.

2020-02-22libqos: rename i2c_send and i2c_recvAlexander Bulekov
The names i2c_send and i2c_recv collide with functions defined in hw/i2c/core.c. This causes an error when linking against libqos and softmmu simultaneously (for example when using qtest inproc). Rename the libqos functions to avoid this.

2020-02-03tests: Silence various warnings with pseriesGreg Kurz
Some default features of the pseries machine are only available with KVM. Warnings are printed when the pseries machine is used with another accelerator: qemu-system-ppc64: warning: TCG doesn't support requested feature, cap-ccf-assist=on qemu-system-ppc64: warning: Firmware Assisted Non-Maskable Interrupts(FWNMI) not supported in TCG qemu-system-ppc64: warning: TCG doesn't support requested feature, cap-ccf-assist=on qemu-system-ppc64: warning: Firmware Assisted Non-Maskable Interrupts(FWNMI) not supported in TCG qemu-system-ppc64: warning: TCG doesn't support requested feature, cap-ccf-assist=on qemu-system-ppc64: warning: Firmware Assisted Non-Maskable Interrupts(FWNMI) not supported in TCG This is annoying for CI since it usually runs without KVM. We already disable features that emit similar warnings thanks to properties of the pseries machine, but this is open-coded in various places. Consolidate the set of properties in a single place. Extend it to silence the above warnings. And use it in the various tests that start pseries machines.
