2025-01-17system: propagate Error to gdbserver_start (and other device setups)Alex Bennée1-31/+28
This started as a clean-up to properly pass a Error handler to the gdbserver_start so we could do the right thing for command line and HMP invocations. Now that we have cleaned up foreach_device_config_or_exit() in earlier patches we can further simplify by it by passing &error_fatal instead of checking the return value. Having a return value is still useful for HMP though so tweak the return to use a simple bool instead.

2025-01-15system/runstate: Fix regression, clarify BQL status of exit notifiersPhil Dennis-Jordan1-0/+1
By changing the way the main QEMU event loop is invoked, I inadvertently changed the BQL status of exit notifiers: some of them implicitly assumed they would be called with the BQL held; the BQL is however not held during the exit(status) call in qemu_default_main(). Instead of attempting to ensuring we always call exit() from the BQL - including any transitive calls - this change adds a BQL lock guard to qemu_run_exit_notifiers, ensuring the BQL will always be held in the exit notifiers. Additionally, the BQL promise is now documented at the qemu_{add,remove}_exit_notifier() declarations.

2025-01-13hw/qdev: Check machine_hotplug_handler in hotplug_unplug_allowed_commonAkihiko Odaki1-11/+3
Commit 03fcbd9dc508 ("qdev: Check for the availability of a hotplug controller before adding a device") says: > The qdev_unplug() function contains a g_assert(hotplug_ctrl) > statement, so QEMU crashes when the user tries to device_add + > device_del a device that does not have a corresponding hotplug > controller. > The code in qdev_device_add() already checks whether the bus has a > proper hotplug controller, but for devices that do not have a > corresponding bus, here is no appropriate check available yet. In that > case we should check whether the machine itself provides a suitable > hotplug controller and refuse to plug the device if none is available. However, it forgot to add the corresponding check to qdev_unplug(). Check the machine hotplug handler once in the common qdev_hotplug_unplug_allowed_common() helper so both hotplug and hot-unplug path are covered.

2024-12-31ui & main loop: Redesign of system-specific main thread event handlingPhil Dennis-Jordan1-4/+34
macOS's Cocoa event handling must be done on the initial (main) thread of the process. Furthermore, if library or application code uses libdispatch, the main dispatch queue must be handling events on the main thread as well. So far, this has affected Qemu in both the Cocoa and SDL UIs, although in different ways: the Cocoa UI replaces the default qemu_main function with one that spins Qemu's internal main event loop off onto a background thread. SDL (which uses Cocoa internally) on the other hand uses a polling approach within Qemu's main event loop. Events are polled during the SDL UI's dpy_refresh callback, which happens to run on the main thread by default. As UIs are mutually exclusive, this works OK as long as nothing else needs platform-native event handling. In the next patch, a new device is introduced based on the ParavirtualizedGraphics.framework in macOS. This uses libdispatch internally, and only works when events are being handled on the main runloop. With the current system, it works when using either the Cocoa or the SDL UI. However, it does not when running headless. Moreover, any attempt to install a similar scheme to the Cocoa UI's main thread replacement fails when combined with the SDL UI. This change tidies up main thread management to be more flexible. * The qemu_main global function pointer is a custom function for the main thread, and it may now be NULL. When it is, the main thread runs the main Qemu loop. This represents the traditional setup. * When non-null, spawning the main Qemu event loop on a separate thread is now done centrally rather than inside the Cocoa UI code. * For most platforms, qemu_main is indeed NULL by default, but on Darwin, it defaults to a function that runs the CFRunLoop. * The Cocoa UI sets qemu_main to a function which runs the NSApplication event handling runloop, as is usual for a Cocoa app. * The SDL UI overrides the qemu_main function to NULL, thus specifying that Qemu's main loop must run on the main thread. * The GTK UI also overrides the qemu_main function to NULL. * For other UIs, or in the absence of UIs, the platform's default behaviour is followed. This means that on macOS, the platform's runloop events are always handled, regardless of chosen UI. The new PV graphics device will thus work in all configurations. There is no functional change on other operating systems. Implementing this via a global function pointer variable is a bit ugly, but it's probably worth investigating the existing UI thread rule violations in the SDL (e.g. #2537) and GTK+ back-ends. Fixing those issues might precipitate requirements similar but not identical to those of the Cocoa UI; hopefully we'll see some kind of pattern emerge, which can then be used as a basis for an overhaul. (In fact, it may turn out to be simplest to split the UI/native platform event thread from the QEMU main event loop on all platforms, with any UI or even none at all.)

vcpu_dirty_rate_stat_collect() uses migration_is_active() to detect whether migration is running or not, in order to get the correct dirty rate period value. However, recently there has been an effort to simplify the migration status API and reduce it to a single migration_is_running() function. To accommodate this, and since the same functionality can be achieved with migration_is_running(), use it instead of migration_is_active().

The memory access logging can be quite verbose which obscures the other messages enabled by this debug switch so separate it by adding a new -d invalid_mem option to make it possible to control it independently of other guest error logs.

2024-12-10bql: check that the BQL is not dropped within marked sectionsPaolo Bonzini1-0/+15
The Big QEMU Lock (BQL) is used to provide interior mutability to Rust code. While BqlCell performs indivisible accesses, an equivalent of RefCell will allow the borrower to hold to the interior content for a long time. If the BQL is dropped, another thread could come and mutate the data from C code (Rust code would panic on borrow_mut() instead). In order to prevent this, add a new BQL primitive that can mark BQL-atomic sections and aborts if the BQL is dropped within them. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2024-11-25qdev-monitor: avoid QemuOpts in QMP device_addStefan Hajnoczi1-14/+28
The QMP device_add monitor command converts the QDict arguments to QemuOpts and then back again to QDict. This process only supports scalar types. Device properties like virtio-blk-pci's iothread-vq-mapping (an array of objects) are silently dropped by qemu_opts_from_qdict() during the QemuOpts conversion even though QAPI is capable of validating them. As a result, hotplugging virtio-blk-pci devices with the iothread-vq-mapping property does not work as expected (the property is ignored). Get rid of the QemuOpts conversion in qmp_device_add() and call qdev_device_add_from_qdict() with from_json=true. Using the QMP command's QDict arguments directly allows non-scalar properties. The HMP is also adjusted since qmp_device_add()'s now expects properly typed JSON arguments and cannot be used from HMP anymore. Move the code that was previously in qmp_device_add() (with QemuOpts conversion and from_json=false) into hmp_device_add() so that its behavior is unchanged. This patch changes the behavior of QMP device_add but not HMP device_add. QMP clients that sent incorrectly typed device_add QMP commands no longer work. This is a breaking change but clients should be using the correct types already. See the netdev_add QAPIfication in commit db2a380c8457 for similar reasoning and object-add in commit 9151e59a8b6e. Unlike those commits, we continue to rely on 'gen': false for the time being. Markus helped me figure this out and even provided a draft patch. The code ended up very close to what he suggested.

The ``-portrait`` and ``-rotate`` options were documented as only working with the PXA LCD device, and all the machine types using that display device were removed in 9.2. These options were intended to simulate a mobile device being rotated by the user, and had three effects: * the display output was rotated by 90, 180 or 270 degrees (implemented in the PXA display device models) * the mouse/trackpad input was rotated the opposite way (implemented in generic code) * the machine model would signal to the guest about its orientation (implemented by e.g. the spitz machine model) Of these three things, the input-rotation was coded without being restricted to boards which supported the full set of device-rotation handling, so in theory the options were usable on other machine models with odd effects (rotating input but not display output). But this was never intended or documented behaviour, so we can reasonably drop these command line arguments without a formal deprecate-and-drop cycle for them. Remove the options, and their implementation and documentation. Describe the removal in removed-features.rst.

2024-09-24reset: Use ResetType for qemu_devices_reset() and MachineClass::reset()Juraj Marcin1-2/+11
Currently, both qemu_devices_reset() and MachineClass::reset() use ShutdownCause for the reason of the reset. However, the Resettable interface uses ResetState, so ShutdownCause needs to be translated to ResetType somewhere. Translating it qemu_devices_reset() makes adding new reset types harder, as they cannot always be matched to a single ShutdownCause here, and devices may need to check the ResetType to determine what to reset and if to reset at all. This patch moves this translation up in the call stack to qemu_system_reset() and updates all MachineClass children to use the ResetType instead.
