2020-05-15qdev: Unrealize must not failMarkus Armbruster
Devices may have component devices and buses. Device realization may fail. Realization is recursive: a device's realize() method realizes its components, and device_set_realized() realizes its buses (which should in turn realize the devices on that bus, except bus_set_realized() doesn't implement that, yet). When realization of a component or bus fails, we need to roll back: unrealize everything we realized so far. If any of these unrealizes failed, the device would be left in an inconsistent state. Must not happen. device_set_realized() lets it happen: it ignores errors in the roll back code starting at label child_realize_fail. Since realization is recursive, unrealization must be recursive, too. But how could a partly failed unrealize be rolled back? We'd have to re-realize, which can fail. This design is fundamentally broken. device_set_realized() does not roll back at all. Instead, it keeps unrealizing, ignoring further errors. It can screw up even for a device with no buses: if the lone dc->unrealize() fails, it still unregisters vmstate, and calls listeners' unrealize() callback. bus_set_realized() does not roll back either. Instead, it stops unrealizing. Fortunately, no unrealize method can fail, as we'll see below. To fix the design error, drop parameter @errp from all the unrealize methods. Any unrealize method that uses @errp now needs an update. This leads us to unrealize() methods that can fail. Merely passing it to another unrealize method cannot cause failure, though. Here are the ones that do other things with @errp: * virtio_serial_device_unrealize() Fails when qbus_set_hotplug_handler() fails, but still does all the other work. On failure, the device would stay realized with its resources completely gone. Oops. Can't happen, because qbus_set_hotplug_handler() can't actually fail here. Pass &error_abort to qbus_set_hotplug_handler() instead. * hw/ppc/spapr_drc.c's unrealize() Fails when object_property_del() fails, but all the other work is already done. On failure, the device would stay realized with its vmstate registration gone. Oops. Can't happen, because object_property_del() can't actually fail here. Pass &error_abort to object_property_del() instead. * spapr_phb_unrealize() Fails and bails out when remove_drcs() fails, but other work is already done. On failure, the device would stay realized with some of its resources gone. Oops. remove_drcs() fails only when chassis_from_bus()'s object_property_get_uint() fails, and it can't here. Pass &error_abort to remove_drcs() instead. Therefore, no unrealize method can fail before this patch. device_set_realized()'s recursive unrealization via bus uses object_property_set_bool(). Can't drop @errp there, so pass &error_abort. We similarly unrealize with object_property_set_bool() elsewhere, always ignoring errors. Pass &error_abort instead. Several unrealize methods no longer handle errors from other unrealize methods: virtio_9p_device_unrealize(), virtio_input_device_unrealize(), scsi_qdev_unrealize(), ... Much of the deleted error handling looks wrong anyway. One unrealize methods no longer ignore such errors: usb_ehci_pci_exit(). Several realize methods no longer ignore errors when rolling back: v9fs_device_realize_common(), pci_qdev_unrealize(), spapr_phb_realize(), usb_qdev_realize(), vfio_ccw_realize(), virtio_device_realize().

kvm_arch_on_sigbus_vcpu() error injection uses source_id as index in etc/hardware_errors to find out Error Status Data Block entry corresponding to error source. So supported source_id values should be assigned here and not be changed afterwards to make sure that guest will write error into expected Error Status Data Block. Before QEMU writes a new error to ACPI table, it will check whether previous error has been acknowledged. If not acknowledged, the new errors will be ignored and not be recorded. For the errors section type, QEMU simulate it to memory section error.

This patch builds Hardware Error Source Table(HEST) via fw_cfg blobs. Now it only supports ARMv8 SEA, a type of Generic Hardware Error Source version 2(GHESv2) error source. Afterwards, we can extend the supported types if needed. For the CPER section, currently it is memory section because kernel mainly wants userspace to handle the memory errors. This patch follows the spec ACPI 6.2 to build the Hardware Error Source table.

2020-05-07spapr/cas: Separate CAS handling from rebuilding the FDTAlexey Kardashevskiy
At the moment "ibm,client-architecture-support" ("CAS") is implemented in SLOF and QEMU assists via the custom H_CAS hypercall which copies an updated flatten device tree (FDT) blob to the SLOF memory which it then uses to update its internal tree. When we enable the OpenFirmware client interface in QEMU, we won't need to copy the FDT to the guest as the client is expected to fetch the device tree using the client interface. This moves FDT rebuild out to a separate helper which is going to be called from the "ibm,client-architecture-support" handler and leaves writing FDT to the guest in the H_CAS handler. This should not cause any behavioral change.

2020-05-04elf_ops: Don't try to g_mapped_file_unref(NULL)Peter Maydell
Calling g_mapped_file_unref() on a NULL pointer is not valid, and glib will assert if you try it. $ qemu-system-arm -M virt -display none -device loader,file=/tmp/bad.elf qemu-system-arm: -device loader,file=/tmp/bad.elf: GLib: g_mapped_file_unref: assertion 'file != NULL' failed (One way to produce an ELF file that fails like this is to copy just the first 16 bytes of a valid ELF file; this is sufficient to fool the code in load_elf_ram_sym() into thinking it's an ELF file and calling load_elf32() or load_elf64().) The failure-exit path in load_elf can be reached from various points in execution, and for some of those we haven't yet called g_mapped_file_new_from_fd(). Add a condition to the unref call so we only call it if we successfully created the GMappedFile to start with. This will fix the assertion; for the specific case of the generic loader it will then fall back from "guess this is an ELF file" to "maybe it's a uImage or a hex file" and eventually to "just load as a raw data file".

If it disabled, any input characters and events are ignored. If this clock remains unconnected, the uart behaves as before (it default to a 50MHz ref clock).

2020-04-30hw/core/clock: introduce clock objectPeter Maydell
This object may be used to represent a clock inside a clock tree. A clock may be connected to another clock so that it receives update, through a callback, whenever the source/parent clock is updated. Although only the root clock of a clock tree controls the values (represented as periods) of all clocks in tree, each clock holds a local state containing the current value so that it can be fetched independently. It will allows us to fullfill migration requirements by migrating each clock independently of others. This is based on the original work of Frederic Konrad.

2020-04-30nrf51: Fix last GPIO CNF addressCameron Esfahani
NRF51_GPIO_REG_CNF_END doesn't actually refer to the start of the last valid CNF register: it's referring to the last byte of the last valid CNF register. This hasn't been a problem up to now, as current implementation in memory.c turns an unaligned 4-byte read from 0x77f to a single byte read and the qtest only looks at the least-significant byte of the register. But when running with patches which fix unaligned accesses in memory.c, the qtest breaks. Considering NRF51 doesn't support unaligned accesses, the simplest fix is to actually set NRF51_GPIO_REG_CNF_END to the start of the last valid CNF register: 0x77c. Now, qtests work with or without the unaligned access patches.
