* include/hw/qdev-properties: Remove DEFINE_PROP_END_OF_LISTRichard Henderson2024-12-191-1/+0
| | | | | | | | | | | | | | Now that all of the Property arrays are counted, we can remove the terminator object from each array. Update the assertions in device_class_set_props to match. With struct Property being 88 bytes, this was a rather large form of terminator. Saves 30k from qemu-system-aarch64.

| | | | | | | | | | | | | | | | | | If the 'i8042' property is not set, mouse events handled by vmmouse_mouse_event() end calling i8042_isa_mouse_fake_event() with a NULL argument, resulting in ps2_mouse_fake_event() being called with invalid PS2MouseState pointer.

* hw/i386: fix vmmouse registrationPavel Dovgalyuk2021-11-011-0/+1
| | | | | | | | | | | | | | According to the logic of vmmouse_update_handler function, vmmouse should be registered as an event handler when it's status is zero. vmmouse_read_id resets the status but does not register the handler.

| | | | | | | | | | | | | | | | | | | | | | | | | In my "build everything" tree, changing hw/qdev-properties.h triggers a recompile of some 2700 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). Many places including hw/qdev-properties.h (directly or via hw/qdev.h) actually need only hw/qdev-core.h. Include hw/qdev-core.h there instead. hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h and hw/qdev-properties.h, which in turn includes hw/qdev-core.h. Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h. While there, delete a few superfluous inclusions of hw/qdev-core.h. Touching hw/qdev-properties.h now recompiles some 1200 objects.
