2020-04-29fuzz: Simplify how we compute available machines and typesMarkus Armbruster
apply_to_qlist(), apply_to_node() work with QObjects. This is designed for use by tests/qtest/qos-test.c, which gets the data in that form via QMP. Goes back to commit fc281c8020 "tests: qgraph API for the qtest driver framework". Commit 275ab39d86 "fuzz: add support for qos-assisted fuzz targets" added another user: qtest/fuzz/qos_fuzz.c. 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.
