2020-09-22qom: simplify object_find_property / object_class_find_propertyDaniel P. Berrangé
When debugging QEMU it is often useful to put a breakpoint on the error_setg_internal method impl. Unfortunately the object_property_add / object_class_property_add methods call object_property_find / object_class_property_find methods to check if a property exists already before adding the new property. As a result there are a huge number of calls to error_setg_internal on startup of most QEMU commands, making it very painful to set a breakpoint on this method. Most callers of object_find_property and object_class_find_property, however, pass in a NULL for the Error parameter. This simplifies the methods to remove the Error parameter entirely, and then adds some new wrapper methods that are able to raise an Error when needed. Signed-off-by: Daniel P.

2020-07-10qom: Put name parameter before value / visitor parameterMarkus Armbruster
The object_property_set_FOO() setters take property name and value in an unusual order: void object_property_set_FOO(Object *obj, FOO_TYPE value, const char *name, Error **errp) Having to pass value before name feels grating. Swap them. Same for object_property_set(), object_property_get(), and object_property_parse(). Convert callers with this Coccinelle script: @@ identifier fun = { object_property_get, object_property_parse, object_property_set_str, object_property_set_link, object_property_set_bool, object_property_set_int, object_property_set_uint, object_property_set, object_property_set_qobject }; expression obj, v, name, errp; @@ - fun(obj, v, name, errp) + fun(obj, name, v, errp) Chokes on hw/arm/musicpal.c's lcd_refresh() with the unhelpful error message "no position information". Convert that one manually. Fails to convert hw/arm/armsse.c, because Coccinelle gets confused by ARMSSE being used both as typedef and function-like macro there. Convert manually. Fails to convert hw/rx/rx-gdbsim.c, because Coccinelle gets confused by RXCPU being used both as typedef and function-like macro there. Convert manually. The other files using RXCPU that way don't need conversion.

2019-08-16sysemu: Split sysemu/runstate.h off sysemu/sysemu.hMarkus Armbruster
sysemu/sysemu.h is a rather unfocused dumping ground for stuff related to the system-emulator. Evidence: * It's included widely: in my "build everything" tree, changing sysemu/sysemu.h still triggers a recompile of some 1100 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h, down from 5400 due to the previous two commits). * It pulls in more than a dozen additional headers. Split stuff related to run state management into its own header sysemu/runstate.h. Touching sysemu/sysemu.h now recompiles some 850 objects. qemu/uuid.h also drops from 1100 to 850, and qapi/qapi-types-run-state.h from 4400 to 4200. Touching new sysemu/runstate.h recompiles some 500 objects. Since I'm touching MAINTAINERS to add sysemu/runstate.h anyway, also add qemu/main-loop.h.

2019-08-16Include hw/qdev-properties.h lessMarkus Armbruster
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.

In my "build everything" tree, changing migration/vmstate.h triggers a recompile of some 2700 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). hw/hw.h supposedly includes it for convenience. Several other headers include it just to get VMStateDescription. The previous commit made that unnecessary. Include migration/vmstate.h only where it's still needed. Touching it now recompiles only some 1600 objects.

2019-02-28hw/arm/armsse: Unify init-svtor and cpuwait handlingPeter Maydell
At the moment the handling of init-svtor and cpuwait initial values is split between armsse.c and iotkit-sysctl.c: the code in armsse.c sets the initial state of the CPU object by setting the init-svtor and start-powered-off properties, but the iotkit-sysctl.c code has its own code setting the reset values of its registers (which are then used when updating the CPU when the guest makes runtime changes). Clean this up by making the armsse.c code set properties on the iotkit-sysctl object to define the initial values of the registers, so they always match the initial CPU state, and update the comments in armsse.c accordingly.

2019-02-28hw/arm/iotkit-sysctl: Implement CPUWAIT and INITSVTOR*Peter Maydell
The CPUWAIT register acts as a sort of power-control: if a bit in it is 1 then the CPU will have been forced into waiting when the system was reset (which in QEMU we model as the CPU starting powered off). Writing a 0 to the register will allow the CPU to boot (for QEMU, we model this as powering it on). Note that writing 0 to the register does not power off a CPU. For this to work correctly we need to also honour the INITSVTOR* registers, which let the guest control where the CPU will load its SP and PC from when it comes out of reset.

The iotkit-sysctl device has a register it names INITSVRTOR0. This is actually a typo present in the IoTKit documentation and also in part of the SSE-200 documentation: it should be INITSVTOR0 because it is specifying the initial value of the Secure VTOR register in the CPU.
