2023-10-27target/arm: Implement Neoverse N2 CPU modelPeter Maydell
Implement a model of the Neoverse N2 CPU. This is an Armv9.0-A processor very similar to the Cortex-A710. The differences are: * no FEAT_EVT * FEAT_DGH (data gathering hint) * FEAT_NV (not yet implemented in QEMU) * Statistical Profiling Extension (not implemented in QEMU) * 48 bit physical address range, not 40 * CTR_EL0.DIC = 1 (no explicit icache cleaning needed) * PMCR_EL0.N = 6 (always 6 PMU counters, not 20) Because it has 48-bit physical address support, we can use this CPU in the sbsa-ref board as well as the virt board.

2023-10-27docs/about: Mark the old pc-i440fx-2.0 - 2.3 machine types as deprecatedThomas Huth
As we've seen in the past, it's useful for deprecating old machine types to finally be able to get of legacy code or do other clean-ups (see e.g. commit ea985d235b868047 that was used to drop the PCI code in the 128k bios binaries to free some precious space in those binaries). So let's continue deprecating the oldest pc machine types. QEMU 2.3 has been released 8 years ago, so that's plenty of time since such machine types have been used by default, thus deprecating pc-i440fx-2.0 up to pc-i440fx-2.3 should be fine nowadays.

2023-10-22intel-iommu: Report interrupt remapping faults, fix return valueDavid Woodhouse
A generic X86IOMMUClass->int_remap function should not return VT-d specific values; fix it to return 0 if the interrupt was successfully translated or -EINVAL if not. The VTD_FR_IR_xxx values are supposed to be used to actually raise faults through the fault reporting mechanism, so do that instead for the case where the IRQ is actually being injected. There is more work to be done here, as pretranslations for the KVM IRQ routing table can't fault; an untranslatable IRQ should be handled in userspace and the fault raised only when the IRQ actually happens (if indeed the IRTE is still not valid at that time). But we can work on that later; we can at least raise faults for the direct case.

2023-10-22vhost-user: fix lost reconnectLi Feng
When the vhost-user is reconnecting to the backend, and if the vhost-user fails at the get_features in vhost_dev_init(), then the reconnect will fail and it will not be retriggered forever. The reason is: When the vhost-user fails at get_features, the vhost_dev_cleanup will be called immediately. vhost_dev_cleanup calls 'memset(hdev, 0, sizeof(struct vhost_dev))'. The reconnect path is: vhost_user_blk_event vhost_user_async_close(.. vhost_user_blk_disconnect ..) qemu_chr_fe_set_handlers <----- clear the notifier callback schedule vhost_user_async_close_bh The vhost->vdev is null, so the vhost_user_blk_disconnect will not be called, then the event fd callback will not be reinstalled. All vhost-user devices have this issue, including vhost-user-blk/scsi. With this patch, if the vdev->vdev is null, the fd callback will still be reinstalled.

2023-10-22hw/isa/piix: Implement multi-process QEMU support also for PIIX4Bernhard Beschow
So far multi-process QEMU was only implemented for PIIX3. Move the support into the base class to achieve feature parity between both device models.

2023-10-22hw/isa/piix: Reuse PIIX3's PCI interrupt triggering in PIIX4Bernhard Beschow
Speeds up PIIX4 which resolves an old TODO. Also makes PIIX4 compatible with Xen which relies on pci_bus_fire_intx_routing_notifier() to be fired.

2023-10-22hw/isa/piix: Allow for optional PIT creation in PIIX3Bernhard Beschow
In the PC machine, the PIT is created in board code to allow it to be virtualized with various virtualization techniques. So explicitly disable its creation in the PC machine via a property which defaults to enabled. Once the PIIX implementations are consolidated this default will keep Malta working without further ado.
