| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Let's auto-enable it also when maxmem is specified but no slots are defined. This will result in us properly creating ACPI srat tables, indicating the maximum possible PFN to the guest OS. Based on this, e.g., Linux will enable the swiotlb properly. This avoids having to manually force the switolb on (swiotlb=force) in Linux in case we're booting only using DMA memory (e.g., 2GB on x86-64), and virtio-mem adds memory later on that really needs the swiotlb to be used for DMA. Let's take care of backwards compatibility if somebody has a setup that specifies "maxram" without "slots".

* | qdev: Introduce DEFINE_PROP_RESERVED_REGIONEric Auger2020-07-031-0/+89
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce a new property defining a reserved region: <low address>:<high address>:<type>. This will be used to encode reserved IOVA regions. For instance, in virtio-iommu use case, reserved IOVA regions will be passed by the machine code to the virtio-iommu-pci device (an array of those). The type of the reserved region will match the virtio_iommu_probe_resv_mem subtype value: - VIRTIO_IOMMU_RESV_MEM_T_RESERVED (0) - VIRTIO_IOMMU_RESV_MEM_T_MSI (1) on PC/Q35 machine, this will be used to inform the virtio-iommu-pci device it should bypass the MSI region. The reserved region will be: 0xfee00000:0xfeefffff:1. On ARM, we can declare the ITS MSI doorbell as an MSI region to prevent MSIs from being mapped on guest side.

These are all programming errors here, so passing &error_abort to qbus_set_hotplug_handler() is appropriate. Most of its callers do. Exceptions: * pcie_cap_slot_init(), shpc_init(), spapr_phb_realize() pass NULL, i.e. they ignore errors. * spapr_machine_init() passes &error_fatal. * s390_pcihost_realize(), virtio_serial_device_realize(), s390_pcihost_plug() pass the error to their callers. The latter two keep going after the error, which looks wrong. Drop the @errp parameter, and instead pass &error_abort to object_property_set_link().

Example: -serial null -chardev null,id=chr0 -global isa-serial.chardev=chr0 Special case: attempting to use the same backend both times crashes: $ qemu-system-x86_64 --nodefaults -serial null -global isa-serial.chardev=serial0 Unexpected error in qemu_chr_fe_init() at /work/armbru/qemu/chardev/char-fe.c:220: qemu-system-x86_64: Device 'serial0' is in use Aborted (core dumped) Yet another example: -device with multiple chardev=... (but not device_add, which silently drops all but the last duplicate property). Perhaps chardev property override could be made to work. Perhaps it should. I can't afford the time to figure this out now. What I can do reject usage that leaves backends in unhealthy states. For what it's worth, we've long done the same for netdev properties.

The reference from @bus to @dev is the only strong one. We realize at some later time, either with object_property_set_bool(OBJECT(dev), true, "realized", errp); or its convenience wrapper qdev_init_nofail(dev); If @dev still has no QOM parent then, realizing makes the /machine/unattached/ orphanage its QOM parent. Note that the device returned by qdev_create() is plugged into a bus, but doesn't have a QOM parent, yet. Until it acquires one, unrealizing the bus will hang in bus_unparent(): while ((kid = QTAILQ_FIRST(&bus->children)) != NULL) { DeviceState *dev = kid->child; object_unparent(OBJECT(dev)); } object_unparent() does nothing when its argument has no QOM parent, and the loop spins forever. Device state "no QOM parent, but plugged into bus" is dangerous. Paolo suggested to delay plugging into the bus until realize. We need to plug into the parent bus before we call the device's realize method, in case it uses the parent bus. So the dangerous state still exists, but only within realization, where we can manage it safely. This commit creates infrastructure to do this: dev = qdev_new(type_name); ... qdev_realize_and_unref(dev, bus, errp) Note that @dev becomes a strong reference here. qdev_realize_and_unref() drops it. There is also plain qdev_realize(), which doesn't drop it. The remainder of this series will convert all users to this new interface. Cc: Michael S.

| * hw/i386/vmport: Propagate IOPort read to vCPU EAX registerLiran Alon2020-06-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | vmport_ioport_read() returns the value that should propagate to vCPU EAX register when guest reads VMPort IOPort (i.e. By x86 IN instruction). However, because vmport_ioport_read() calls cpu_synchronize_state(), the returned value gets overridden by the value in QEMU vCPU EAX register. i.e. cpu->env.regs[R_EAX]. To fix this issue, change vmport_ioport_read() to explicitly override cpu->env.regs[R_EAX] with the value it wish to propagate to vCPU EAX register.

| * numa: prevent usage of -M memory-backend and -numa memdev at the same timeIgor Mammedov2020-06-101-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Options -M memory-backend and -numa memdev are mutually exclusive, and if used together, it might lead to a crash in the worst case. For example when the same backend is used with these options together: -m 4G \ -object memory-backend-ram,id=mem0,size=4G \ -M pc,memory-backend=mem0 \ -numa node,memdev=mem0 QEMU will abort with: exec.c:2006: qemu_ram_set_idstr: Assertion `!new_block->idstr[0]' failed. and following backtrace: abort () qemu_ram_set_idstr () vmstate_register_ram () vmstate_register_ram_global () machine_consume_memdev () numa_init_memdev_container () numa_complete_configuration () machine_run_board_init () add a check to error out in case the user tries to use both options at the same time.

| * virtio-balloon: Implement support for page poison reporting featureAlexander Duyck2020-06-091-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to make certain to advertise support for page poison reporting if we want to actually get data on if the guest will be poisoning pages. Add a value for reporting the poison value being used if page poisoning is enabled in the guest. With this we can determine if we will need to skip free page reporting when it is enabled in the future. The value currently has no impact on existing balloon interfaces. In the case of existing balloon interfaces the onus is on the guest driver to reapply whatever poison is in place. When we add free page reporting the poison value is used to determine if we can perform in-place page reporting. The expectation is that a reported page will already contain the value specified by the poison, and the reporting of the page should not change that value.
