2024-02-28plugins: Use different helpers when reading registersAkihiko Odaki
This avoids optimizations incompatible when reading registers.

2024-02-28plugins: add qemu_plugin_num_vcpus functionPierrick Bouvier
We now keep track of how many vcpus were started. This way, a plugin can easily query number of any vcpus at any point of execution, which unifies user and system mode workflows.

2024-02-28plugins: remove previous n_vcpus functions from APIPierrick Bouvier
This information is already accessible using qemu_info_t during plugin install. We will introduce another function (qemu_plugin_num_vcpus) which represent how many cpus were enabled, by tracking new cpu indexes. It's a breaking change, so we bump API version.

2024-02-28migration: stop vm for cprSteve Sistare
When migration for cpr is initiated, stop the vm and set state RUN_STATE_FINISH_MIGRATE before ram is saved. This eliminates the possibility of ram and device state being out of sync, and guarantees that a guest in the suspended state remains suspended, because qmp_cont rejects a cont command in the RUN_STATE_FINISH_MIGRATE state.

2024-02-27hw/core/reset: Implement qemu_register_reset via qemu_register_resettablePeter Maydell
Reimplement qemu_register_reset() via qemu_register_resettable(). We define a new LegacyReset object which implements Resettable and defines its reset hold phase method to call a QEMUResetHandler function. When qemu_register_reset() is called, we create a new LegacyReset object and add it to the simulation_reset ResettableContainer. When qemu_unregister_reset() is called, we find the LegacyReset object in the container and remove it. This implementation of qemu_unregister_reset() means we'll end up scanning the ResetContainer's list of child objects twice, once to find the LegacyReset object, and once in g_ptr_array_remove(). In theory we could avoid this by having the ResettableContainer interface include a resettable_container_remove_with_equal_func() that took a callback method so that we could use g_ptr_array_find_with_equal_func() and g_ptr_array_remove_index(). But we don't expect qemu_unregister_reset() to be called frequently or in hot paths, and we expect the simulation_reset container to usually not have many children.

2024-02-27hw/core/reset: Add qemu_{register, unregister}_resettable()Peter Maydell
Implement new functions qemu_register_resettable() and qemu_unregister_resettable(). These are intended to be three-phase-reset aware equivalents of the old qemu_register_reset() and qemu_unregister_reset(). Instead of passing in a function pointer and opaque, you register any QOM object that implements the Resettable interface. The implementation is simple: we have a single global instance of a ResettableContainer, which we reset in qemu_devices_reset(), and the Resettable objects passed to qemu_register_resettable() are added to it.

2024-02-27hw/core: Add ResetContainer which holds objects implementing ResettablePeter Maydell
Implement a ResetContainer. This is a subclass of Object, and it implements the Resettable interface. The container holds a list of arbitrary other objects which implement Resettable, and when the container is reset, all the objects it contains are also reset. This will allow us to have a 3-phase-reset equivalent of the old qemu_register_reset() API: we will have a single "simulation reset" top level ResetContainer, and objects in it are the equivalent of the old QEMUResetHandler functions. The qemu_register_reset() API manages its list of callbacks using a QTAILQ, but here we use a GPtrArray for our list of Resettable children: we expect the "remove" operation (which will need to do an iteration through the list) to be fairly uncommon, and we get simpler code with fewer memory allocations. Since there is currently no listed owner in MAINTAINERS for the existing reset-related source files, create a new section for them, and add these new files there also.

2024-02-27include/qom/object.h: New OBJECT_DEFINE_SIMPLE_TYPE{, _WITH_INTERFACES} macrosPeter Maydell
We have an OBJECT_DEFINE_TYPE_EXTENDED macro, plus several variations on it, which emits the boilerplate for the TypeInfo and ensures it is registered with the type system. However, all the existing macros insist that the type being defined has its own FooClass struct, so they aren't useful for the common case of a simple leaf class which doesn't have any new methods or any other need for its own class struct (that is, for the kind of type that OBJECT_DECLARE_SIMPLE_TYPE declares). Pull the actual implementation of OBJECT_DEFINE_TYPE_EXTENDED out into a new DO_OBJECT_DEFINE_TYPE_EXTENDED which parameterizes the value we use for the class_size field. This lets us add a new OBJECT_DEFINE_SIMPLE_TYPE which does the same job as the various existing OBJECT_DEFINE_*_TYPE_* family macros for this kind of simple type, and the variant OBJECT_DEFINE_SIMPLE_TYPE_WITH_INTERFACES for when the type will implement some interfaces.

2024-02-27aspeed: fix hardcode boot address 0Jamin Lin
In the previous design of ASPEED SOCs QEMU model, it set the boot address at "0" which was the hardcode setting for ast10x0, ast2600, ast2500 and ast2400. According to the design of ast2700, it has a bootmcu(riscv-32) which is used for executing SPL and initialize DRAM and copy u-boot image from SPI/Flash to DRAM at address 0x400000000 at SPL boot stage. Then, CPUs(cortex-a35) execute u-boot, kernel and rofs. Currently, qemu not support emulate two CPU architectures at the same machine. Therefore, qemu will only support to emulate CPU(cortex-a35) side for ast2700 and the boot address is "0x4 00000000". Fixed hardcode boot address "0" for future models using a different mapping address.
