2017-11-16build-sys: restrict vmcoreinfo to fw_cfg+dma capable targetsMarc-André Lureau
vmcoreinfo is built for all targets. However, it requires fw_cfg with DMA operations support (write operation). Restrict vmcoreinfo exposure to architectures that are supporting FW_CFG_DMA, that is arm-virt and x86 only atm.

2017-11-16NUMA: Enable adding NUMA node implicitlyDou Liyang
Linux and Windows need ACPI SRAT table to make memory hotplug work properly, however currently QEMU doesn't create SRAT table if numa options aren't present on CLI. Which breaks both linux and windows guests in certain conditions: * Windows: won't enable memory hotplug without SRAT table at all * Linux: if QEMU is started with initial memory all below 4Gb and no SRAT table present, guest kernel will use nommu DMA ops, which breaks 32bit hw drivers when memory is hotplugged and guest tries to use it with that drivers. Fix above issues by automatically creating a numa node when QEMU is started with memory hotplug enabled but without '-numa' options on CLI. (PS: auto-create numa node only for new machine types so not to break migration). Which would provide SRAT table to guests without explicit -numa options on CLI and would allow: * Windows: to enable memory hotplug * Linux: switch to SWIOTLB DMA ops, to bounce DMA transfers to 32bit allocated buffers that legacy drivers/hw can handle.

2017-11-16hw/pci-host: Fix x86 Host Bridges 64bit PCI holeMarcel Apfelbaum
Currently there is no MMIO range over 4G reserved for PCI hotplug. Since the 32bit PCI hole depends on the number of cold-plugged PCI devices and other factors, it is very possible is too small to hotplug PCI devices with large BARs. Fix it by reserving 2G for I4400FX chipset in order to comply with older Win32 Guest OSes and 32G for Q35 chipset. Even if the new defaults of pci-hole64-size will appear in "info qtree" also for older machines, the property was not implemented so no changes will be visible to guests. Note this is a regression since prev QEMU versions had some range reserved for 64bit PCI hotplug.

2017-11-16fix: unrealize virtio device if we fail to hotplug itlinzhecheng
If we fail to hotplug virtio-blk device and then suspend or shutdown VM, qemu is likely to crash. Re-production steps: 1. Run VM named vm001 2. Create a virtio-blk.xml which contains wrong configurations: <disk device="lun" rawio="yes" type="block"> <driver cache="none" io="native" name="qemu" type="raw" /> <source dev="/dev/mapper/11-dm" /> <target bus="virtio" dev="vdx" /> </disk> 3. Run command : virsh attach-device vm001 virtio-blk.xml error: Failed to attach device from blk-scsi.xml error: internal error: unable to execute QEMU command 'device_add': Please set scsi=off for virtio-blk devices in order to use virtio 1.0 it means hotplug virtio-blk device failed. 4. Suspend or shutdown VM will leads to qemu crash Problem happens in virtio_vmstate_change which is called by vm_state_notify: vdev’s parent_bus is NULL, so qdev_get_parent_bus(DEVICE(vdev)) will crash. virtio_vmstate_change is added to the list vm_change_state_head at virtio_blk_device_realize(virtio_init), but after hotplug virtio-blk failed, virtio_vmstate_change will not be removed from vm_change_state_head. Adding unrealize function of virtio-blk device can solve this problem. Signed-off-by: linzhecheng <linzhecheng@huawei.com> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Reviewed-by: Michael S.

When using the emulated XICS, the 'info pic' monitor command shows: CPU 0 XIRR=ff000000 ((nil)) PP=ff MFRR=ff ICS 1000..13ff 0x10040060340 1000 MSI 05 00 1001 MSI 05 00 1002 MSI 05 00 1003 MSI ff 00 1004 LSI ff 00 1005 LSI ff 00 1006 LSI ff 00 1007 LSI ff 00 1008 MSI 05 00 1009 MSI 05 00 100a MSI 05 00 100b MSI 05 00 100c MSI 05 00 but when using the in-kernel XICS with the very same guest, we get: CPU 0 XIRR=00000000 ((nil)) PP=ff MFRR=ff ICS 1000..13ff 0x10032e00340 1000 MSI ff 00 1001 MSI ff 00 1002 MSI ff 00 1003 MSI ff 00 1004 LSI ff 00 1005 LSI ff 00 1006 LSI ff 00 1007 LSI ff 00 1008 MSI ff 00 1009 MSI ff 00 100a MSI ff 00 100b MSI ff 00 100c MSI ff 00 ie, all irqs are masked and XIRR is null, while we should get the same output as with the emulated XICS. If the guest is then migrated, 'info pic' shows the expected values on both source and destination. The problem is that QEMU doesn't synchronize with KVM before printing the XICS state. Migration happens to fix the output because it enforces synchronization with KVM. To fix the invalid output of 'info pic', this patch introduces a new synchronize_state operation for both ICPStateClass and ICSStateClass. The ICP operation relies on run_on_cpu() in order to kick the vCPU and avoid sleeping on KVM_GET_ONE_REG.

2017-11-14target/ppc: correct htab shift for hash on radixSam Bobroff
KVM HV will soon support running a guest in hash mode on a POWER9 host running in radix mode (see [1]), however the guest currently fails to boot. This is because the "htab_shift" value (the size of the MMU's hash table) is added to the device tree before KVM has had a chance to change it. If the host is in hash mode, KVM does not need to change it and so the problem is not seen, but when the host is in radix mode a change is required and we see a problem. To fix this, move the call spapr_setup_hpt_and_vrma() (where htab_shift could be changed) up a little so that it's called before spapr_h_cas_compose_response() (where htab_shift is added to the device tree).

2017-11-13hw: add .min_cpus and .default_cpus fields to machine_classEmilio G. Cota
max_cpus needs to be an upper bound on the number of vCPUs initialized; otherwise TCG region initialization breaks. Some boards initialize a hard-coded number of vCPUs, which is not captured by the global max_cpus and therefore breaks TCG initialization. Fix it by adding the .min_cpus field to machine_class. This commit also changes some user-facing behaviour: we now die if -smp is below this hard-coded vCPU minimum instead of silently ignoring the passed -smp value (sometimes announcing this by printing a warning). However, the introduction of .default_cpus lessens the likelihood that users will notice this: if -smp isn't set, we now assign the value in .default_cpus to both smp_cpus and max_cpus. IOW, if a user does not set -smp, they always get a correct number of vCPUs. This change fixes 3468b59 ("tcg: enable multiple TCG contexts in softmmu", 2017-10-24), which broke TCG initialization for some ARM boards.

2017-11-13Fix eepro100 simple transmission modeMike Nawrocki
The simple transmission mode was treating the area immediately after the transmit command block (TCB) as if it were a transmit buffer descriptor, when in reality it is simply the packet data. This change simply copies the data following the TCB into the packet buffer. Signed-off-by: Mike Nawrocki <michael.nawrocki@gtri.gatech.edu> Reviewed-by: Michael S.

2017-11-08s390x/pci: let pci devices start in configured modeChristian Borntraeger
Currently, to enable a pci device in the guest, the user has to issue echo 1 > /sys/bus/pci/slots/00000000/power. This is not what people expect. On an LPAR, the user can put a PCI device in configured or deconfigured state via IOCDS. The "start in deconfigured state" can be used for "sharing" a pci function across LPARs. This is not what we are going to use in KVM, so always start configured.

Actual number of interrupt pins isn't known in ppce500_init_mpic() so a hardcoded number was used, which causes a crash with older openpic. Instead, return the DeviceState* and change ppce500_init() to call qdev_get_gpio_in() to get only the irq pins which are needed.

2017-11-07hw/intc/arm_gicv3_its: Don't abort on table save failureEric Auger
The ITS is not fully properly reset at the moment. Caches are not emptied. After a reset, in case we attempt to save the state before the bound devices have registered their MSIs and after the 1st level table has been allocated by the ITS driver (device BASER is valid), the first level entries are still invalid. If the device cache is not empty (devices registered before the reset), vgic_its_save_device_tables fails with -EINVAL. This causes a QEMU abort().

2017-11-07hw/intc/arm_gicv3_its: Fix the VM termination in vm_change_state_handler()Shanker Donthineni
The commit cddafd8f353d ("hw/intc/arm_gicv3_its: Implement state save /restore") breaks the backward compatibility with the older kernels where vITS save/restore support is not available. The vmstate function vm_change_state_handler() should not be registered if the running kernel doesn't support ITS save/restore feature. Otherwise VM instance will be killed whenever vmstate callback function is invoked. Observed a virtual machine shutdown with QEMU-2.10+linux-4.11 when testing the reboot command "virsh reboot <domain> --mode acpi" instead of reboot.
