xlnx-zynqmp-pmu: Initial commit of the ZynqMP PMU 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.

New convenience wrapper object_initialize_child() automates the size argument, and passes &error_abort and no properties.

hw/microblaze/zynqmp: Use object_initialize_child for correct ref. counting 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 (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. 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. 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>

xlnx-zynqmp-pmu: Initial commit of the ZynqMP PMU 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.

qom: Less verbose object_initialize_child() All users of object_initialize_child() pass the obvious child size argument. Almost all pass &error_abort and no properties. Tiresome. Rename object_initialize_child() to object_initialize_child_with_props() to free the name. New convenience wrapper object_initialize_child() automates the size argument, and passes &error_abort and no properties. Rename object_initialize_childv() to object_initialize_child_with_propsv() for consistency. Convert callers with this Coccinelle script: @@ expression parent, propname, type; expression child, size; symbol error_abort; @@ - object_initialize_child(parent, propname, OBJECT(child), size, type, &error_abort, NULL) + object_initialize_child(parent, propname, child, size, type, &error_abort, NULL) @@ expression parent, propname, type; expression child; symbol error_abort; @@ - object_initialize_child(parent, propname, child, sizeof(*child), type, &error_abort, NULL) + object_initialize_child(parent, propname, child, type) @@ expression parent, propname, type; expression child; symbol error_abort; @@ - object_initialize_child(parent, propname, &child, sizeof(child), type, &error_abort, NULL) + object_initialize_child(parent, propname, &child, type) @@ expression parent, propname, type; expression child, size, err; expression list props; @@ - object_initialize_child(parent, propname, child, size, type, err, props) + object_initialize_child_with_props(parent, propname, child, size, type, err, props) Note that Coccinelle chokes on ARMSSE typedef vs. macro in hw/arm/armsse.c.
