We should be supporting everything (e.g., device unplug, "dynamic-memslots") that we already support for the virtio-pci variant. With a Linux guest that supports virtio-mem (and has automatic memory onlining properly configured) the following example will work: 1. Start a VM with 4G initial memory and a virtio-mem device with a maximum capacity of 16GB: qemu/build/qemu-system-s390x \ --enable-kvm \ -m 4G,maxmem=20G \ -nographic \ -smp 8 \ -hda Fedora-Server-KVM-40-1.14.s390x.qcow2 \ -chardev socket,id=monitor,path=/var/tmp/monitor,server,nowait \ -mon chardev=monitor,mode=readline \ -object memory-backend-ram,id=mem0,size=16G,reserve=off \ -device virtio-mem-ccw,id=vmem0,memdev=mem0,dynamic-memslots=on 2. Query the current size of virtio-mem device: (qemu) info memory-devices Memory device [virtio-mem]: "vmem0" memaddr: 0x100000000 node: 0 requested-size: 0 size: 0 max-size: 17179869184 block-size: 1048576 memdev: /objects/mem0 3.

Try to hotunplug all memory again, shrinking to 0GB: (qemu) qom-set vmem0 requested-size 0G (qemu) info memory-devices Memory device [virtio-mem]: "vmem0" memaddr: 0x100000000 node: 0 requested-size: 0 size: 0 max-size: 17179869184 block-size: 1048576 memdev: /objects/mem0 6.

| * s390x/virtio-ccw: add support for virtio based memory devicesDavid Hildenbrand2024-12-215-1/+270
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Let's implement support for abstract virtio based memory devices, using the virtio-pci implementation as an orientation. Wire them up in the machine hotplug handler, taking care of s390x page size limitations. As we neither support virtio-mem or virtio-pmem yet, the code is effectively unused. We'll implement support for virtio-mem based on this next. Note that we won't wire up the virtio-pci variant (should currently be impossible due to lack of support for MSI-X), but we'll add a safety net to reject plugging them in the pre-plug handler.

Note that CONFIG_MEM_DEVICE will be selected automatically once we add support for devices. Just like on other architectures, the region container for memory devices is placed directly above our initial memory. For now, we only align the start address of the region up to 1 GiB, but we won't add any additional space to the region for internal alignment purposes; this can be done in the future if really required. The RAM size returned via SCLP is not modified, as this only covers initial RAM (and standby memory we don't implement) and not memory devices; clarify that in the docs of read_SCP_info(). Existing OSes without support for memory devices will keep working as is, even when memory devices would be attached the VM. Guest OSs which support memory devices, such as virtio-mem, will consult diag500(), to find out the maximum possible pfn. Guest OSes that don't support memory devices, don't have to be changed and will continue relying on information provided by SCLP. There are no remaining maxram_size users in s390x code, and the remaining ram_size users only care about initial RAM: * hw/s390x/ipl.c * hw/s390x/s390-hypercall.c * hw/s390x/sclp.c * target/s390x/kvm/pv.c Message-ID: <20241219144115.2820241-11-david@redhat.com> Acked-by: Michael S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With memory devices, we will have storage attributes for memory that exceeds the initial ram size. Further, we can easily have memory holes, for which there (currently) are no storage attributes. In particular, with memory holes, KVM_S390_SET_CMMA_BITS will fail to set some storage attributes. So let's do it like we handle storage keys migration, relying on guest_phys_blocks_append(). However, in contrast to storage key migration, we will handle it on the migration destination. This is a preparation for virtio-mem support. Note that ever since the "early migration" feature was added (x-early-migration), the state of device blocks (plugged/unplugged) is migrated early such that guest_phys_blocks_append() will properly consider all currently plugged memory blocks and skip any unplugged ones. In the future, we should try getting rid of the large temporary buffer and also not send any attributes for any memory holes, just so they get ignored on the destination.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A guest OS that supports memory hotplug / memory devices must during boot be aware of the maximum possible physical memory address that it might have to handle at a later stage during its runtime. For example, the maximum possible memory address might be required to prepare the kernel virtual address space accordingly (e.g., select page table hierarchy depth). On s390x there is currently no such mechanism that is compatible with paravirtualized memory devices, because the whole SCLP interface was designed around the idea of "storage increments" and "standby memory". Paravirtualized memory devices we want to support, such as virtio-mem, have no intersection with any of that, but could co-exist with them in the future if ever needed. In particular, a guest OS must never detect and use device memory without the help of a proper device driver. Device memory must not be exposed in any firmware-provided memory map (SCLP or diag260 on s390x). For this reason, these memory devices will be places in memory *above* the "maximum storage increment" exposed via SCLP. Let's provide a new diag500 subcode to query the memory limit determined in s390_memory_init(). Message-ID: <20241219144115.2820241-8-david@redhat.com> Acked-by: Michael S.

| | | | | | | | | | | | | | | | | | While adding the new flexible boot order feature on s390x recently, we missed to add the "loadparm" property to the scsi-hd and scsi-cd devices. This property is required on s390x to pass the information to the boot loader about which kernel should be started or whether the boot menu should be shown. But even more serious: The missing property is now causing trouble with the corresponding libvirt patches that assume that the "loadparm" property is either settable for all bootable devices (when the "boot order" feature is implemented in QEMU), or none (meaning the behaviour of older QEMUs that only allowed one "loadparm" at the machine level). To fix this broken situation, let's implement the "loadparm" property in for the SCSI devices, too.

| | | | | | | | | | | | | | | | Commit bb185de423 ("s390x: Add individual loadparm assignment to CCW device") added a "loadparm" property to all CCW devices. This was a little bit unfortunate, since this property is only useful for devices that can be used for booting, but certainly it is not useful for devices like virtio-gpu or virtio-tablet. Thus let's restrict the property to CCW devices that we can boot from (i.e. virtio-block, virtio-net and vfio-ccw devices).

However, it seems like libvirt is still adding pci-bridge devices automatically to the guests' XML definitions (when adding a PCI device to a non-zero PCI bus), so these guests are now broken due to the missing pci-bridge in the QEMU binary. To avoid disruption of the users, let's re-enable the pci-bridge device on s390x for the time being.

| | | | | | | | | | | | | | | | | | | | Currently, both qemu_devices_reset() and MachineClass::reset() use ShutdownCause for the reason of the reset. However, the Resettable interface uses ResetState, so ShutdownCause needs to be translated to ResetType somewhere. Translating it qemu_devices_reset() makes adding new reset types harder, as they cannot always be matched to a single ShutdownCause here, and devices may need to check the ResetType to determine what to reset and if to reset at all. This patch moves this translation up in the call stack to qemu_system_reset() and updates all MachineClass children to use the ResetType instead.
