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.

2019-05-24hw/microblaze/zynqmp: Use object_initialize_child for correct ref. countingPhilippe Mathieu-Daudé
As explained in commit aff39be0ed97: Both functions, object_initialize() and object_property_add_child() increase the reference counter of the new object, so one of the references has to be dropped afterwards to get the reference counting right. Otherwise the child object will not be properly cleaned up when the parent gets destroyed. Thus let's use now object_initialize_child() instead to get the reference counting here right. This patch was generated using the following Coccinelle script (with a bit of manual fix-up for overly long lines): @use_object_initialize_child@ expression parent_obj; expression child_ptr; expression child_name; expression child_type; expression child_size; expression errp; @@ ( - object_initialize(child_ptr, child_size, child_type); + object_initialize_child(parent_obj, child_name, child_ptr, child_size, + child_type, &error_abort, NULL); ... when != parent_obj - object_property_add_child(parent_obj, child_name, OBJECT(child_ptr), NULL); ... ?- object_unref(OBJECT(child_ptr)); | - object_initialize(child_ptr, child_size, child_type); + object_initialize_child(parent_obj, child_name, child_ptr, child_size, + child_type, errp, NULL); ... when != parent_obj - object_property_add_child(parent_obj, child_name, OBJECT(child_ptr), errp); ... ?- object_unref(OBJECT(child_ptr)); ) While the object_initialize() function doesn't take an 'Error *errp' argument, the object_initialize_child() does. Since this code is used when a machine is created (and is not yet running), we deliberately choose to use the &error_abort argument instead of ignoring errors if an object creation failed.

Otherwise the child object will not be properly cleaned up when the parent gets destroyed. Thus let's use now object_initialize_child() instead to get the reference counting here right. This patch was generated using the following Coccinelle script (then manually modified to use numbered IPI name) @use_sysbus_init_child_obj_missing_parent@ expression child_ptr; expression child_type; expression child_size; @@ - object_initialize(child_ptr, child_size, child_type); ... - qdev_set_parent_bus(DEVICE(child_ptr), sysbus_get_default()); ... ?- object_unref(OBJECT(child_ptr)); + sysbus_init_child_obj(OBJECT(PARENT_OBJ), "CHILD_NAME", child_ptr, + child_size, child_type); We let the SoC adopt the IPI children.

Since this code is used when a machine is created (and is not yet running), we deliberately choose to use the &error_abort argument instead of ignoring errors if an object creation failed. This choice also matches when using sysbus_init_child_obj(), since its code is: void sysbus_init_child_obj(Object *parent, const char *childname, void *child, size_t childsize, const char *childtype) { object_initialize_child(parent, childname, child, childsize, childtype, &error_abort, NULL); qdev_set_parent_bus(DEVICE(child), sysbus_get_default()); } Suggested-by: Eduardo Habkost <ehabkost@redhat.com> Inspired-by: Thomas Huth <thuth@redhat.com> Signed-off-by: Philippe Mathieu-Daudé <philmd@redhat.com> Message-Id: <20190507163416.24647-14-philmd@redhat.com> Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Reviewed-by: Alistair Francis <alistair.francis@wdc.com> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>

2019-05-24hw/microblaze/zynqmp: Move the IPI state into the PMUSoC statePhilippe Mathieu-Daudé
The Inter Processor Interrupt is a block part of the SoC, not the "machine" (talking about machine is borderline with the PMU, since it is embedded into the ZynqMP SoC, but currentl QEMU doesn't support multi-arch cores). Move the IPI state to the SoC state, this will simplify the review of the next patch.

2018-01-26xlnx-zynqmp-pmu: Initial commit of the ZynqMP PMUAlistair Francis
The Xilinx ZynqMP SoC has two main processing systems in it. The ARM processing system (which is already modeled in QEMU) and the MicroBlaze Power Management Unit (PMU). This is the inital work for adding support for the PMU. The PMU susbsystem runs along side the ARM system on hardware, but due to architecture limitations in QEMU the two instances are seperate for the time being. Let's follow the same setup we do with the ARM system, where there is an SoC device and a ZCU102 board. Although the PMU is less board specific we are still going to follow the same split as maybe in future we can connect the PMU device to the ARM ZCU102 board. As the machine will be fairly small let's keep them both together in one file. Signed-off-by: Alistair Francis <alistair.francis@xilinx.com> Reviewed-by: Edgar E.
