2024-03-26qapi: document parameters of query-cpu-model-* QAPI commandsDavid Hildenbrand
Let's document the parameters of these commands, so we can remove them from the "documentation-exceptions" list. While at it, extend the "Returns:" documentation as well, fixing a wrong use of CpuModelBaselineInfo vs. CpuModelCompareInfo for query-cpu-model-comparison.

2024-03-26qapi: Improve migration TLS documentationMarkus Armbruster
MigrateSetParameters is about setting parameters, and MigrationParameters is about querying them. Their documentation of @tls-creds and @tls-hostname has residual damage from a failed attempt at de-duplicating them (see commit de63ab61241 "migrate: Share common MigrationParameters struct" and commit 1bda8b3c695 "migration: Unshare MigrationParameters struct for now"). MigrateSetParameters documentation issues: * It claims plain text mode "was reported by omitting tls-creds" before 2.9. MigrateSetParameters is not used for reporting, so this is misleading. Delete. * It similarly claims hostname defaulting to migration URI "was reported by omitting tls-hostname" before 2.9. Delete as well. Rephrase the remaining @tls-hostname contents for clarity. Enum MigrationParameter mirrors the members of struct MigrateSetParameters. Differences to MigrateSetParameters's member documentation are pointless. Copy the new text to MigrationParameter. MigrationParameters documentation issues: * @tls-creds runs the two last sentences together without punctuation. Fix that. * Much of the contents on @tls-hostname only applies to setting parameters, resulting in confusion. Replace by a suitable abridged version of the new MigrateSetParameters text, and a note on @tls-hostname omission in 2.8. Additional damage is due to flawed doc fix commit 66fcb9d651d (qapi/migration: Add missing tls-authz documentation): since it copied the missing MigrateSetParameters text from MigrationParameters instead of MigrationParameter, the part on recreating @tls-authz on the fly is missing.

2024-03-12qom: new object to associate device to NUMA nodeAnkit Agrawal
NVIDIA GPU's support MIG (Mult-Instance GPUs) feature [1], which allows partitioning of the GPU device resources (including device memory) into several (upto 8) isolated instances. Each of the partitioned memory needs a dedicated NUMA node to operate. The partitions are not fixed and they can be created/deleted at runtime. Unfortunately Linux OS does not provide a means to dynamically create/destroy NUMA nodes and such feature implementation is not expected to be trivial. The nodes that OS discovers at the boot time while parsing SRAT remains fixed. So we utilize the Generic Initiator (GI) Affinity structures that allows association between nodes and devices. Multiple GI structures per BDF is possible, allowing creation of multiple nodes by exposing unique PXM in each of these structures. Implement the mechanism to build the GI affinity structures as Qemu currently does not. Introduce a new acpi-generic-initiator object to allow host admin link a device with an associated NUMA node. Qemu maintains this association and use this object to build the requisite GI Affinity Structure. When multiple NUMA nodes are associated with a device, it is required to create those many number of acpi-generic-initiator objects, each representing a unique device:node association. Following is one of a decoded GI affinity structure in VM ACPI SRAT. [0C8h 0200 1] Subtable Type : 05 [Generic Initiator Affinity] [0C9h 0201 1] Length : 20 [0CAh 0202 1] Reserved1 : 00 [0CBh 0203 1] Device Handle Type : 01 [0CCh 0204 4] Proximity Domain : 00000007 [0D0h 0208 16] Device Handle : 00 00 20 00 00 00 00 00 00 00 00 00 00 00 00 00 [0E0h 0224 4] Flags (decoded below) : 00000001 Enabled : 1 [0E4h 0228 4] Reserved2 : 00000000 [0E8h 0232 1] Subtable Type : 05 [Generic Initiator Affinity] [0E9h 0233 1] Length : 20 An admin can provide a range of acpi-generic-initiator objects, each associating a device (by providing the id through pci-dev argument) to the desired NUMA node (using the node argument). Currently, only PCI device is supported. For the grace hopper system, create a range of 8 nodes and associate that with the device using the acpi-generic-initiator object. While a configuration of less than 8 nodes per device is allowed, such configuration will prevent utilization of the feature to the fullest. The following sample creates 8 nodes per PCI device for a VM with 2 PCI devices and link them to the respecitve PCI device using acpi-generic-initiator objects: -numa node,nodeid=2 -numa node,nodeid=3 -numa node,nodeid=4 \ -numa node,nodeid=5 -numa node,nodeid=6 -numa node,nodeid=7 \ -numa node,nodeid=8 -numa node,nodeid=9 \ -device vfio-pci-nohotplug,host=0009:01:00.0,bus=pcie.0,addr=04.0,rombar=0,id=dev0 \ -object acpi-generic-initiator,id=gi0,pci-dev=dev0,node=2 \ -object acpi-generic-initiator,id=gi1,pci-dev=dev0,node=3 \ -object acpi-generic-initiator,id=gi2,pci-dev=dev0,node=4 \ -object acpi-generic-initiator,id=gi3,pci-dev=dev0,node=5 \ -object acpi-generic-initiator,id=gi4,pci-dev=dev0,node=6 \ -object acpi-generic-initiator,id=gi5,pci-dev=dev0,node=7 \ -object acpi-generic-initiator,id=gi6,pci-dev=dev0,node=8 \ -object acpi-generic-initiator,id=gi7,pci-dev=dev0,node=9 \ -numa node,nodeid=10 -numa node,nodeid=11 -numa node,nodeid=12 \ -numa node,nodeid=13 -numa node,nodeid=14 -numa node,nodeid=15 \ -numa node,nodeid=16 -numa node,nodeid=17 \ -device vfio-pci-nohotplug,host=0009:01:01.0,bus=pcie.0,addr=05.0,rombar=0,id=dev1 \ -object acpi-generic-initiator,id=gi8,pci-dev=dev1,node=10 \ -object acpi-generic-initiator,id=gi9,pci-dev=dev1,node=11 \ -object acpi-generic-initiator,id=gi10,pci-dev=dev1,node=12 \ -object acpi-generic-initiator,id=gi11,pci-dev=dev1,node=13 \ -object acpi-generic-initiator,id=gi12,pci-dev=dev1,node=14 \ -object acpi-generic-initiator,id=gi13,pci-dev=dev1,node=15 \ -object acpi-generic-initiator,id=gi14,pci-dev=dev1,node=16 \ -object acpi-generic-initiator,id=gi15,pci-dev=dev1,node=17 \ Link: https://www.nvidia.com/en-in/technologies/multi-instance-gpu [1] Cc: Jonathan Cameron <qemu-devel@nongnu.org> Cc: Alex Williamson <alex.williamson@redhat.com> Cc: Markus Armbruster <armbru@redhat.com> Reviewed-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Acked-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Ankit Agrawal <ankita@nvidia.com> Message-Id: <20240308145525.10886-2-ankita@nvidia.com> Reviewed-by: Michael S.

2024-03-12qmp: Added new command to retrieve eBPF blob.Andrew Melnychenko
Now, the binary objects may be retrieved by id. It would require for future qmp commands that may require specific eBPF blob. Added command "request-ebpf". This command returns eBPF program encoded base64. The program taken from the skeleton and essentially is an ELF object that can be loaded in the future with libbpf. The reason to use the command to provide the eBPF object instead of a separate artifact was to avoid issues related to finding the eBPF itself. eBPF object is an ELF binary that contains the eBPF program and eBPF map description(BTF). Overall, eBPF object should contain the program and enough metadata to create/load eBPF with libbpf. As the eBPF maps/program should correspond to QEMU, the eBPF can't be used from different QEMU build. The first solution was a helper that comes with QEMU and loads appropriate eBPF objects. And the issue is to find a proper helper if the system has several different QEMUs installed and/or built from the source, which helpers may not be compatible. Another issue is QEMU updating while there is a running QEMU instance. With an updated helper, it may not be possible to hotplug virtio-net device to the already running QEMU. Overall, requesting the eBPF object from QEMU itself solves possible failures with acceptable effort.

2024-03-01migration/ram: Introduce 'mapped-ram' migration capabilityFabiano Rosas
Add a new migration capability 'mapped-ram'. The core of the feature is to ensure that RAM pages are mapped directly to offsets in the resulting migration file instead of being streamed at arbitrary points. The reasons why we'd want such behavior are: - The resulting file will have a bounded size, since pages which are dirtied multiple times will always go to a fixed location in the file, rather than constantly being added to a sequential stream. This eliminates cases where a VM with, say, 1G of RAM can result in a migration file that's 10s of GBs, provided that the workload constantly redirties memory. - It paves the way to implement O_DIRECT-enabled save/restore of the migration stream as the pages are ensured to be written at aligned offsets. - It allows the usage of multifd so we can write RAM pages to the migration file in parallel. For now, enabling the capability has no effect. The next couple of patches implement the core functionality.

Character backends are actually QOM types. When a backend's compile-time conditional QOM type is not compiled in, creation fails with "'FOO' is not a valid char driver name". Okay, except introspecting chardev-add with query-qmp-schema doesn't work then: the backend type is there even though the QOM type isn't. A management application can work around this issue by using qom-list-types instead. Fix the issue anyway: add the conditionals to the QAPI schema.
