2024-05-27hw/core/machine: move compatibility flags for VirtIO-net USO to machine 8.1Fiona Ebner
Migration from an 8.2 or 9.0 binary to an 8.1 binary with machine version 8.1 can fail with: > kvm: Features 0x1c0010130afffa7 unsupported. Allowed features: 0x10179bfffe7 > kvm: Failed to load virtio-net:virtio > kvm: error while loading state for instance 0x0 of device '0000:00:12.0/virtio-net' > kvm: load of migration failed: Operation not permitted The series 53da8b5a99 virtio-net: Add support for USO features 9da1684954 virtio-net: Add USO flags to vhost support. f03e0cf63b tap: Add check for USO features 2ab0ec3121 tap: Add USO support to tap device. only landed in QEMU 8.2, so the compatibility flags should be part of machine version 8.1. Moving the flags unfortunately breaks forward migration with machine version 8.1 from a binary without this patch to a binary with this patch.

2024-03-13hw/nvme: add machine compatibility parameter to enable msix exclusive barKlaus Jensen
Commit 1901b4967c3f ("hw/block/nvme: move msix table and pba to BAR 0") moved the MSI-X table and PBA to BAR 0 to make room for enabling CMR and PMR at the same time. As reported by Julien Grall in #2184, this breaks migration through system hibernation. Add a machine compatibility parameter and set it on machines pre 6.0 to enable the old behavior automatically, restoring the hibernation migration support.

2023-11-28qdev: Fix crash in array property getterKevin Wolf
Passing an uninitialised list to visit_start_list() happens to work for the QObject output visitor because it treats the pointer as an opaque value and never dereferences it, but the string output visitor expects a valid list to check if it has more than one element. The existing code crashes with the string output visitor if the uninitialised value is non-NULL. Passing an explicit NULL would fix the crash, but still result in wrong output. Rework get_prop_array() so that it conforms to the expectations that the string output visitor has. This includes building a real list first and using visit_next_list() to iterate it.

The Intel 82576EB GbE Controller say that the Physical and Virtual Functions support Function Level Reset. Add the capability to the PF device model using device property "x-pcie-flr-init" which is "on" by default and "off" for machines <= 8.1 to preserve compatibility. The FLR capability of the VF model is defined according to the FLR property of the PF, this to avoid adding an extra compatibility property.

2023-11-10qdev: Rework array properties based on list visitorKevin Wolf
Until now, array properties are actually implemented with a hack that uses multiple properties on the QOM level: a static "foo-len" property and after it is set, dynamically created "foo[i]" properties. In external interfaces (-device on the command line and device_add in QMP), this interface was broken by commit f3558b1b ('qdev: Base object creation on QDict rather than QemuOpts') because QDicts are unordered and therefore it could happen that QEMU tried to set the indexed properties before setting the length, which fails and effectively makes array properties inaccessible. In particular, this affects the 'ports' property of the 'rocker' device, which used to be configured like this: -device rocker,len-ports=2,ports[0]=dev0,ports[1]=dev1 This patch reworks the external interface so that instead of using a separate top-level property for the length and for each element, we use a single true array property that accepts a list value. In the external interfaces, this is naturally expressed as a JSON list and makes array properties accessible again. The new syntax looks like this: -device '{"driver":"rocker","ports":["dev0","dev1"]}' Creating an array property on the command line without using JSON format is currently not possible. This could be fixed by switching from QemuOpts to a keyval parser, which however requires consideration of the compatibility implications. All internal users of devices with array properties go through qdev_prop_set_array() at this point, so updating it takes care of all of them.

2023-11-10qdev: Make netdev properties work as list elementsKevin Wolf
The 'name' parameter of QOM setters is primarily used to specify the name of the currently parsed input element in the visitor interface. For top-level qdev properties, this is always set and matches 'prop->name'. However, for list elements it is NULL, because each element of a list doesn't have a separate name. Passing a non-NULL value runs into assertion failures in the visitor code. Therefore, using 'name' in error messages is not right for property types that are used in lists, because "(null)" (or even a segfault) isn't very helpful to identify what QEMU is complaining about. Change netdev properties to use 'prop->name' instead, which will contain the name of the array property after switching array properties to lists in the external interface. (This is still not perfect, as it doesn't identify which element in the list caused the error, but strictly better than before.)

The initialization and exit hooks will not affect the state of vCPU outside TCG context, but they may depend on the state of vCPU. Therefore, it's better to call plugin hooks after the vCPU state is fully initialized and before it gets uninitialized.

2023-11-01migration: mode parameterSteve Sistare
Create a mode migration parameter that can be used to select alternate migration algorithms. The default mode is normal, representing the current migration algorithm, and does not need to be explicitly set. No functional change until a new mode is added, except that the mode is shown by the 'info migrate' command.

2023-10-20CPU topology: extend with s390 specificsPierre Morel
S390 adds two new SMP levels, drawers and books to the CPU topology. S390 CPUs have specific topology features like dedication and entitlement. These indicate to the guest information on host vCPU scheduling and help the guest make better scheduling decisions. Add the new levels to the relevant QAPI structs. Add all the supported topology levels, dedication and entitlement as properties to S390 CPUs. Create machine-common.json so we can later include it in machine-target.json also.

current code sets PCI_SEC_LATENCY_TIMER to RW, but for pcie to pcie bridges it must be RO 0 according to pci express spec which says: This register does not apply to PCI Express.

For PCI Express to PCI/PCI-X Bridges, refer to the [PCIe-to-PCI-PCI-X-Bridge] for requirements for this register. also, fix typo in comment where it's made writeable - this typo is likely what prevented us noticing we violate this requirement in the 1st place.

2023-09-19machine: Improve error message when using default RAM backend idDavid Hildenbrand
For migration purposes, users might want to reuse the default RAM backend id, but specify a different memory backend. For example, to reuse "pc.ram" on q35, one has to set -machine q35,memory-backend=pc.ram Only then, can a memory backend with the id "pc.ram" be created manually. Let's improve the error message by improving the hint. Use error_append_hint() -- which in turn requires ERRP_GUARD().

2023-07-10pcie: Specify 0 for ARI next function numbersAkihiko Odaki
The current implementers of ARI are all SR-IOV devices. The ARI next function number field is undefined for VF according to PCI Express Base Specification Revision 5.0 Version 1.0 section 9.3.7.7. The PF still requires some defined value so end the linked list formed with the field by specifying 0 as required for any ARI implementation according to section 7.8.7.2. For migration, the field will keep having 1 as its value on the old QEMU machine versions.
