2021-10-05hw/i386/acpi: fix conflicting IO address range for acpi pci hotplug in q35Ani Sinha1-1/+1
Change caf108bc58790 ("hw/i386/acpi-build: Add ACPI PCI hot-plug methods to Q35") selects an IO address range for acpi based PCI hotplug for q35 arbitrarily. It starts at address 0x0cc4 and ends at 0x0cdb. At the time when the patch was written but the final version of the patch was not yet pushed upstream, this address range was free and did not conflict with any other IO address ranges. However, with the following change, this address range was no longer conflict free as in this change, the IO address range (value of ACPI_PCIHP_SIZE) was incremented by four bytes: b32bd763a1ca92 ("pci: introduce acpi-index property for PCI device") This can be seen from the output of QMP command 'info mtree' : 0000000000000600-0000000000000603 (prio 0, i/o): acpi-evt 0000000000000604-0000000000000605 (prio 0, i/o): acpi-cnt 0000000000000608-000000000000060b (prio 0, i/o): acpi-tmr 0000000000000620-000000000000062f (prio 0, i/o): acpi-gpe0 0000000000000630-0000000000000637 (prio 0, i/o): acpi-smi 0000000000000cc4-0000000000000cdb (prio 0, i/o): acpi-pci-hotplug 0000000000000cd8-0000000000000ce3 (prio 0, i/o): acpi-cpu-hotplug It shows that there is a region of conflict between IO regions of acpi pci hotplug and acpi cpu hotplug. Unfortunately, the change caf108bc58790 did not update the IO address range appropriately before it was pushed upstream to accommodate the increased length of the IO address space introduced in change b32bd763a1ca92. Due to this bug, windows guests complain 'This device cannot find enough free resources it can use' in the device manager panel for extended IO buses. This issue also breaks the correct functioning of pci hotplug as the following shows that the IO space for pci hotplug has been truncated: (qemu) info mtree -f FlatView #0 AS "I/O", root: io Root memory region: io 0000000000000cc4-0000000000000cd7 (prio 0, i/o): acpi-pci-hotplug 0000000000000cd8-0000000000000cf7 (prio 0, i/o): acpi-cpu-hotplug Therefore, in this fix, we adjust the IO address range for the acpi pci hotplug so that it does not conflict with cpu hotplug and there is no truncation of IO spaces. The starting IO address of PCI hotplug region has been decremented by four bytes in order to accommodate four byte increment in the IO address space introduced by change b32bd763a1ca92 ("pci: introduce acpi-index property for PCI device") After fixing, the following are the corrected IO ranges: 0000000000000600-0000000000000603 (prio 0, i/o): acpi-evt 0000000000000604-0000000000000605 (prio 0, i/o): acpi-cnt 0000000000000608-000000000000060b (prio 0, i/o): acpi-tmr 0000000000000620-000000000000062f (prio 0, i/o): acpi-gpe0 0000000000000630-0000000000000637 (prio 0, i/o): acpi-smi 0000000000000cc0-0000000000000cd7 (prio 0, i/o): acpi-pci-hotplug 0000000000000cd8-0000000000000ce3 (prio 0, i/o): acpi-cpu-hotplug This change has been tested using a Windows Server 2019 guest VM. Windows no longer complains after this change.

2021-10-05vhost-vsock: handle common features in vhost-vsock-commonStefano Garzarella6-28/+43
virtio-vsock features, like VIRTIO_VSOCK_F_SEQPACKET, can be handled by vhost-vsock-common parent class. In this way, we can reuse the same code for all virtio-vsock backends (i.e. vhost-vsock, vhost-user-vsock). Let's move `seqpacket` property to vhost-vsock-common class, add vhost_vsock_common_get_features() used by children, and disable `seqpacket` for vhost-user-vsock device for machine types < 6.2. The behavior of vhost-vsock device doesn't change; vhost-user-vsock device now supports `seqpacket` property.

2021-10-05vhost-vsock: fix migration issue when seqpacket is supportedStefano Garzarella3-3/+20
Commit 1e08fd0a46 ("vhost-vsock: SOCK_SEQPACKET feature bit support") enabled the SEQPACKET feature bit. This commit is released with QEMU 6.1, so if we try to migrate a VM where the host kernel supports SEQPACKET but machine type version is less than 6.1, we get the following errors: Features 0x130000002 unsupported. Allowed features: 0x179000000 Failed to load virtio-vhost_vsock:virtio error while loading state for instance 0x0 of device '0000:00:05.0/virtio-vhost_vsock' load of migration failed: Operation not permitted Let's disable the feature bit for machine types < 6.1. We add a new OnOffAuto property for this, called `seqpacket`. When it is `auto` (default), QEMU behaves as before, trying to enable the feature, when it is `on` QEMU will fail if the backend (vhost-vsock kernel module) doesn't support it.

2021-10-04qemu-options: Add missing "sockets=2, maxcpus=2" to CLI "-smp 2"Yanan Wang1-1/+1
There is one numa config example in qemu-options.hx currently using "-smp 2" and assuming that there will be 2 sockets and 2 cpus totally. However now the actual calculation logic of missing sockets and cores is not immutable and is considered liable to change. Although we will get maxcpus=2 finally based on current parser, it's always stable to specify it explicitly. So "-smp 2,sockets=2,maxcpus=2" will be optimal when we expect multiple sockets and 2 cpus totally.
