| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

This also allows to make them all accept size suffixes, either via DEFINE_PROP_BLOCKSIZE or via DEFINE_PROP_SIZE32. Also, since min_io_size is exposed to the guest by scsi and virtio-blk devices as an uint16_t in units of logical blocks, introduce an additional check in blkconf_blocksizes to prevent its silent truncation.

* block: Add qdev_prop_drive_iothread property typeKevin Wolf2019-06-041-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | Some qdev block devices have support for iothreads and take care of the AioContext they are running in, but most devices don't know about any of this. For the latter category, the qdev drive property must make sure that their BlockBackend is in the main AioContext. Unfortunately, while the current code just does the same thing for devices that do support iothreads, this is not correct and it would show as soon as we actually try to keep a consistent AioContext assignment across all nodes and users of a block graph subtree: If a node is already in a non-default AioContext because of one of its users, attaching a new device should still be possible if that device can work in the same AioContext. Switching the node back to the main context first and only then into the device AioContext causes failure (because the existing user wouldn't allow the switch to the main context). So devices that support iothreads need a different kind of drive property that leaves the node in its current AioContext, but by using this type, the device promises to check later that it can work with this context. This patch adds the qdev infrastructure that allows devices to signal that they handle iothreads and qdev should leave the AioContext alone. Signed-off-by: Kevin Wolf <kwolf@redhat.com>

| | | | | | | | | | | | | | | | | | | | | In my "build everything" tree, a change to the types in qapi-schema.json triggers a recompile of about 4800 out of 5100 objects. The previous commit split up qmp-commands.h, qmp-event.h, qmp-visit.h, qapi-types.h. Each of these headers still includes all its shards. Reduce compile time by including just the shards we actually need. To illustrate the benefits: adding a type to qapi/migration.json now recompiles some 2300 instead of 4800 objects. The next commit will improve it further.

|/ | | | | | | | | | | | | | UUIDs (GUIDs) are widely used in VMBus-related stuff, so a dedicated property type becomes helpful. The property accepts a string-formatted UUID or a special keyword "auto" meaning a randomly generated UUID; the latter is also the default when the property is not given a value explicitly.

* qdev: support properties which don't set a default valuePeter Maydell2017-07-171-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some situations it's useful to have a qdev property which doesn't automatically set its default value when qdev_property_add_static is called (for instance when the default value is not constant). Support this by adding a flag to the Property struct indicating whether to set the default value. This replaces the existing test for whether the PropertyInfo set_default_value function pointer is NULL, and we set the .set_default field to true for all those cases of struct Property which use a PropertyInfo with a non-NULL set_default_value, so behaviour remains the same as before. This gives us the semantics of: * if .set_default is true, then .info->set_default_value must be not NULL, and .defval is used as the the default value of the property * otherwise, the property system does not set any default, and the field will retain whatever initial value it was given by the device's .instance_init method We define two new macros DEFINE_PROP_SIGNED_NODEFAULT and DEFINE_PROP_UNSIGNED_NODEFAULT, to cover the most plausible use cases of wanting to set an integer property with no default value.

| | | | | | | | | | | | In DEFINE_PROP_ARRAY, because we use a PropertyInfo (qdev_prop_arraylen) which has a .set_default_value member we will set the field to a default value. That default value will be zero, by the C rule that struct initialization sets unmentioned members to zero if at least one member is initialized. However it's clearer to state it explicitly.
