2020-01-23qemu-block-drivers: Convert to rSTPeter Maydell
The qemu-block-drivers documentation is currently in docs/qemu-block-drivers.texi in Texinfo format, which we present to the user as: * a qemu-block-drivers manpage * a section of the main qemu-doc HTML documentation Convert the documentation to rST format, and present it to the user as: * a qemu-block-drivers manpage * part of the system/ Sphinx manual This follows the same pattern we've done for qemu-ga and qemu-nbd. We have to drop a cross-reference from the documentation of the -cdrom option back to the qemu-block-drivers documentation, since they're no longer within the same texinfo document. As noted in a comment, the manpage output is slightly compromised due to limitations in Sphinx. In an ideal world, the HTML output would have the various headings like 'Disk image file formats' as top-level section headings (which then appear in the overall system manual's table-of-contents), and it would not have the section headings which make sense only for the manpage like 'synopsis', 'description', and 'see also'. Unfortunately, the mechanism Sphinx provides for restricting pieces of documentation is limited to the point of being flawed: the 'only::' directive is implemented as a filter that is applied at a very late stage in the document processing pipeline, rather than as an early equivalent of an #ifdef. This means that Sphinx's process of identifying which section heading markup styles are which levels of heading gets confused if the 'only::' directive contains section headings which would affect the heading-level of a later heading. I have opted to prioritise making the HTML format look better, with the compromise being that in the manpage the 'Disk image file formats' &c headings are top-level headings rather than being sub-headings under the traditional 'Description' top-level section title.

2020-01-23qemu-nbd: Convert invocation documentation to rSTPeter Maydell
The qemu-nbd documentation is currently in qemu-nbd.texi in Texinfo format, which we present to the user as: * a qemu-nbd manpage * a section of the main qemu-doc HTML documentation Convert the documentation to rST format, and present it to the user as: * a qemu-nbd manpage * part of the interop/ Sphinx manual This follows the same pattern as commit 27a296fce982 did for the qemu-ga manpage. All the content of the old manpage is retained, except that I have dropped the "This is free software; see the source for copying conditions. There is NO warranty..." text that was in the old AUTHOR section; Sphinx's manpage builder doesn't expect that much text in the AUTHOR section, and since none of our other manpages have it it seems easiest to delete it rather than try to figure out where else in the manpage to put it. The only other textual change is that I have had to give the --nocache option its own description ("Equivalent to --cache=none") because Sphinx doesn't have an equivalent of using item/itemx to share a description between two options. Some minor aspects of the formatting have changed, to suit what is easiest for Sphinx to output. (The most notable is that Sphinx option section option syntax doesn't support '--option foo=bar' with bar underlined rather than bold, so we have to switch to '--option foo=BAR' instead.) The contents of qemu-option-trace.texi are now duplicated in docs/interop/qemu-option-trace.rst.inc, until such time as we complete the conversion of the other files which use it; since it has had only 3 changes in 3 years, this shouldn't be too awkward a burden. (We use .rst.inc because if this file fragment has a .rst extension then Sphinx complains about not seeing it in a toctree.)

2020-01-22acpi: cpuhp: add CPHP_GET_CPU_ID_CMD commandIgor Mammedov
Firmware can enumerate present at boot APs by broadcasting wakeup IPI, so that woken up secondary CPUs could register them-selves. However in CPU hotplug case, it would need to know architecture specific CPU IDs for possible and hotplugged CPUs so it could prepare environment for and wake hotplugged AP. Reuse and extend existing CPU hotplug interface to return architecture specific ID for currently selected CPU in 2 registers: - lower 32 bits in ACPI_CPU_CMD_DATA_OFFSET_RW - upper 32 bits in ACPI_CPU_CMD_DATA2_OFFSET_R On x86, firmware will use CPHP_GET_CPU_ID_CMD for fetching the APIC ID when handling hotplug SMI. Later, CPHP_GET_CPU_ID_CMD will be used on ARM to retrieve MPIDR, which serves the similar to APIC ID purpose.

No functional change in practice, patch only aims to properly document (in spec and code) intended usage of the reserved space. The new field is to be used for 2 purposes: - detection of modern CPU hotplug interface using CPHP_GET_NEXT_CPU_WITH_EVENT_CMD command. procedure will be described in follow up patch: "acpi: cpuhp: spec: add typical usecases" - for returning upper 32 bits of architecture specific CPU ID, for new CPHP_GET_CPU_ID_CMD command added by follow up patch: "acpi: cpuhp: add CPHP_GET_CPU_ID_CMD command" Change is backward compatible with 4.2 and older machines, as field was unconditionally reserved and always returned 0x0 if modern CPU hotplug interface was enabled.

2019-11-01target/arm/kvm: host cpu: Add support for sve<N> propertiesAndrew Jones
Allow cpu 'host' to enable SVE when it's available, unless the user chooses to disable it with the added 'sve=off' cpu property. Also give the user the ability to select vector lengths with the sve<N> properties. We don't adopt 'max' cpu's other sve property, sve-max-vq, because that property is difficult to use with KVM. That property assumes all vector lengths in the range from 1 up to and including the specified maximum length are supported, but there may be optional lengths not supported by the host in that range. With KVM one must be more specific when enabling vector lengths.

2019-11-01target/arm/cpu64: max cpu: Introduce sve<N> propertiesAndrew Jones
Introduce cpu properties to give fine control over SVE vector lengths. We introduce a property for each valid length up to the current maximum supported, which is 2048-bits. The properties are named, e.g. sve128, sve256, sve384, sve512, ..., where the number is the number of bits. See the updates to docs/arm-cpu-features.rst for a description of the semantics and for example uses. Note, as sve-max-vq is still present and we'd like to be able to support qmp_query_cpu_model_expansion with guests launched with e.g. -cpu max,sve-max-vq=8 on their command lines, then we do allow sve-max-vq and sve<N> properties to be provided at the same time, but this is not recommended, and is why sve-max-vq is not mentioned in the document. If sve-max-vq is provided then it enables all lengths smaller than and including the max and disables all lengths larger. It also has the side-effect that no larger lengths may be enabled and that the max itself cannot be disabled. Smaller non-power-of-two lengths may, however, be disabled, e.g. -cpu max,sve-max-vq=4,sve384=off provides a guest the vector lengths 128, 256, and 512 bits.

2019-11-01target/arm/monitor: Introduce qmp_query_cpu_model_expansionAndrew Jones
Add support for the query-cpu-model-expansion QMP command to Arm. We do this selectively, only exposing CPU properties which represent optional CPU features which the user may want to enable/disable. Additionally we restrict the list of queryable cpu models to 'max', 'host', or the current type when KVM is in use. And, finally, we only implement expansion type 'full', as Arm does not yet have a "base" CPU type. More details and example queries are described in a new document (docs/arm-cpu-features.rst). Note, certainly more features may be added to the list of advertised features, e.g. 'vfp' and 'neon'. The only requirement is that we can detect invalid configurations and emit failures at QMP query time. For 'vfp' and 'neon' this will require some refactoring to share a validation function between the QMP query and the CPU realize functions.

2019-10-29net/virtio: add failover supportJens Freimann
This patch adds support to handle failover device pairs of a virtio-net device and a (vfio-)pci device, where the virtio-net acts as the standby device and the (vfio-)pci device as the primary. The general idea is that we have a pair of devices, a (vfio-)pci and a emulated (virtio-net) device. Before migration the vfio device is unplugged and data flows to the emulated device, on the target side another (vfio-)pci device is plugged in to take over the data-path. In the guest the net_failover module will pair net devices with the same MAC address. To achieve this we need: 1. Provide a callback function for the should_be_hidden DeviceListener. It is called when the primary device is plugged in. Evaluate the QOpt passed in to check if it is the matching primary device. It returns if the device should be hidden or not. When it should be hidden it stores the device options in the VirtioNet struct and the device is added once the VIRTIO_NET_F_STANDBY feature is negotiated during virtio feature negotiation. If the virtio-net devices are not realized at the time the (vfio-)pci devices are realized, we need to connect the devices later. This way we make sure primary and standby devices can be specified in any order. 2. Register a callback for migration status notifier. When called it will unplug its primary device before the migration happens. 3. Register a callback for the migration code that checks if a device needs to be unplugged from the guest.
