2016-06-17test: start vhost-user reconnect testMarc-André Lureau
This is a simple reconnect test, that simply checks if vhost-user reconnection is possible and restore the state. A more complete test would actually manipulate and check the ring contents (such extended testing would benefit from the libvhost-user proposed in QEMU list to avoid duplication of ring manipulations) Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Victor Kaplansky <victork@redhat.com> Reviewed-by: Michael S.

2016-06-17vhost-net: save & restore vring enable stateMarc-André Lureau
A driver may change the vring enable state at run time but vhost-user backend may not be present (a contrived example is when the backend is disconnected and the device is reconfigured after driver rebinding) Restore the vring state when the vhost-user backend is started, so it can process the ring.

2016-06-17tests/vhost-user-bridge: workaround stale vring baseMarc-André Lureau
This patch is a similar solution to what Yuanhan Liu/Huawei Xie have suggested for DPDK. When vubr quits (killed or crashed), a restart of vubr would get stale vring base from QEMU. That would break the kernel virtio net completely, making it non-work any more, unless a driver reset is done. So, instead of getting the stale vring base from QEMU, Huawei suggested we could get a proper one from used->idx. This works because the queues packets are processed in order.

Current QEMU cannot detect vhost-user backend disconnection. The patch adds ability to know it. To know disconnection, add watcher to detect G_IO_HUP event. When G_IO_HUP event is detected, the disconnected socket will be read to cause a CHR_EVENT_CLOSED.

2016-06-17pci: fix pci_requester_id()Peter Xu
This fix SID verification failure when IOMMU IR is enabled with PCI bridges. Existing pci_requester_id() is more like getting BDF info only. Renaming it to pci_get_bdf(). Meanwhile, we provide the correct implementation to get requester ID. VT-d spec 5.1.1 is a good reference to go, though it talks only about interrupt delivery, the rule works exactly the same for non-interrupt cases. Currently, there are three use cases for pci_requester_id(): - PCIX status bits: here we need BDF only, not requester ID. Replacing with pci_get_bdf(). - PCIe Error injection and MSI delivery: for both these cases, we are looking for requester IDs. Here we should use the new impl. To avoid a PCI walk every time we send MSI message, one requester_id cache field is added to PCIDevice to cache the result when initialize PCI device.

2016-06-14target-arm: Fix reset and migration of TTBCR(S)Peter Maydell
Commit 6459b94c26dd666badb3 broke reset and migration of the AArch32 TTBCR(S) register if the guest used non-LPAE page tables. This is because the AArch32 TTBCR register definition is marked as ARM_CP_ALIAS, meaning that the AArch64 variant has to handle migration and reset. Although AArch64 TCR_EL3 doesn't need to care about the mask and base_mask fields, AArch32 may do so, and so we must use the special TTBCR reset and raw write functions to ensure they are set correctly. This doesn't affect TCR_EL2, because the AArch32 equivalent of that is HTCR, which never uses the non-LPAE page table variant.

2016-06-14qdev_try_create(): Assert that devices we put onto the system bus are ↵Peter Maydell
SysBusDevices If qdev_try_create() is passed NULL for the bus, it will automatically put the newly created device onto the default system bus. However if the device is not actually a SysBusDevice then this will result in later crashes (for instance when running the monitor "info qtree" command) because code reasonably assumes that all devices on the system bus are system bus devices. Generally the mistake is that the calling code should create the object with object_new(TYPE_FOO) rather than qdev_create(NULL, TYPE_FOO); see commit 6749695eaaf346c1 for an example of fixing this bug. Assert in qdev_try_create() if the device isn't suitable to put on the system bus, so that this mistake results in failure earlier and more reliably.

2016-06-14s390x/kvm: Fixup interrupt type for non-adapter I/O interruptsChristian Borntraeger
The current algorithm for I/O interrupts would result in a wrong interrupt type for subchannel numbers fffe and ffff. In addition a non adapter interrupt might look like an adapter interrupt for any subchannel number that has the 0x0400 bit set. No kernel has ever used the type outside logging - and the logging was wrong all the time. For everything else the kernel used the interrupt parameters. Let's use the KVM_S390_INT_IO macro as for adapter interrupts.

2016-06-14s390x: Limit s390-ccw machines to 248 CPUsChristian Borntraeger
The sclp scp read info call fills in a buffer with information about the system. With more than 248 CPUs we overflow the 4k buffer of the SCCB, leading to random data corruption. Basically ALL guest operating systems call scp read info, so let's limit the machines to 248 CPUs to make it obvious that >=249 does not work. As KVM also limits itself to 248 and TCG on s390 does not support SMP, this should cause no regression for any user as no VMs with more than 248 VCPUs were ever possible.
