2019-04-08test qgraph.c: Fix segs due to out of scope defaultDr. David Alan Gilbert
The test uses the trick: if (!opts) { opts = &(QOSGraph...Options) { }; } in a couple of places, however the temporary created by the &() {} goes out of scope at the bottom of the if, and results in a seg or assert when opts-> fields are used (on fedora 30's gcc 9).

2019-04-08tests/libqos: fix usage of bool in pci-spapr.cJafar Abdi
Clean up wrong usage of FALSE and TRUE in places that use "bool" from stdbool.h. FALSE and TRUE (with capital letters) are the constants defined by glib for being used with the "gboolean" type of glib.

2019-03-12ahci-test: Drop dependence on global_qtestEric Blake
Managing parallel connections to two different monitors via the implicit global_qtest makes it hard to copy-and-paste code to tests that are not aware of the implicit state; the management of global_qtest is even harder to follow because it was masked behind set_context(). Instead, explicitly pass QTestState* around (generally, by reusing the member already present in ahci->parent QOSState), and call explicit qtest_* functions on all places that interact with a monitor. We can assert that the conversion is correct by checking that global_qtest remains NULL throughout the test (a later patch that changes global_qtest to not be a public global variable will drop the assertions).

2018-08-16tests: Clean up string interpolation around qtest_qmp_device_add()Markus Armbruster
Leaving interpolation into JSON to qmp() is more robust than building QMP input manually, as explained in the commit before previous. qtest_qmp_device_add() and its wrappers interpolate into JSON as follows: * qtest_qmp_device_add() interpolates members into a JSON object. * So do its wrappers qpci_plug_device_test() and usb_test_hotplug(). * usb_test_hotplug() additionally interpolates strings and numbers into JSON strings. Clean them up: * Have qtest_qmp_device_add() take its extra device properties as arguments for qdict_from_jsonf_nofail() instead of a string containing JSON members. * Drop qpci_plug_device_test(), use qtest_qmp_device_add() directly. * Change usb_test_hotplug() parameter @port to string, to avoid interpolation. Interpolate @hcd_id separately. Bonus: gets rid of a non-literal format string. A step towards compile-time format string checking without triggering -Wformat-nonliteral.

2018-08-16tests: Clean up string interpolation into QMP input (simple cases)Markus Armbruster
When you build QMP input manually like this cmd = g_strdup_printf("{ 'execute': 'migrate'," "'arguments': { 'uri': '%s' } }", uri); rsp = qmp(cmd); g_free(cmd); you're responsible for escaping the interpolated values for JSON. Not done here, and therefore works only for sufficiently nice @uri. For instance, if @uri contained a single "'", qobject_from_vjsonf_nofail() would abort. A sufficiently nasty @uri could even inject unwanted members into the arguments object. Leaving interpolation into JSON to qmp() is more robust: rsp = qmp("{ 'execute': 'migrate', 'arguments': { 'uri': %s } }", uri); It's also more concise. Clean up the simple cases where we interpolate exactly a JSON value. Bonus: gets rid of non-literal format strings.

2018-06-25ahci: fix FIS I bit and PIO Setup FIS interruptPaolo Bonzini
The "I" bit in PIO Setup and D2H FISes is exclusively a device concept and the irqstatus register in the controller does not matter. The SATA spec says when it should be one; for D2H FISes in practice it is always set, while the PIO Setup FIS has several subcases that are documented in the patch. Also, the PIO Setup FIS interrupt is actually generated _after_ data has been received. Someone should probably spend some time reading the SATA specification and figuring out the more obscure fields in the PIO Setup FIS, but this is enough to fix SeaBIOS booting from ATAPI CD-ROMs over an AHCI controller.

2018-06-08ahci: move PIO Setup FIS before transfer, fix it for ATAPI commandsJohn Snow
The PIO Setup FIS is written in the PIO:Entry state, which comes before the ATA and ATAPI data transfer states. As a result, the PIO Setup FIS interrupt is now raised before DMA ends for ATAPI commands, and tests have to be adjusted. This is also hinted by the description of the command header in the AHCI specification, where the "A" bit is described as When ‘1’, indicates that a PIO setup FIS shall be sent by the device indicating a transfer for the ATAPI command. and also by the description of the ACMD (ATAPI command region): The ATAPI command must be either 12 or 16 bytes in length. The length transmitted by the HBA is determined by the PIO setup FIS that is sent by the device requesting the ATAPI command. QEMU, which conflates the "generator" and the "receiver" of the FIS into one device, always uses ATAPI_PACKET_SIZE, aka 12, for the length.
