2016-09-15vfio/pci: Fix regression in MSI routing configurationDavid Gibson1-1/+3
d1f6af6 "kvm-irqchip: simplify kvm_irqchip_add_msi_route" was a cleanup of kvmchip routing configuration, that was mostly intended for x86. However, it also contains a subtle change in behaviour which breaks EEH[1] error recovery on certain VFIO passthrough devices on spapr guests. So far it's only been seen on a BCM5719 NIC on a POWER8 server, but there may be other hardware with the same problem. It's also possible there could be circumstances where it causes a bug on x86 as well, though I don't know of any obvious candidates. Prior to d1f6af6, both vfio_msix_vector_do_use() and vfio_add_kvm_msi_virq() used msg == NULL as a special flag to mark this as the "dummy" vector used to make the host hardware state sync with the guest expected hardware state in terms of MSI configuration. Specifically that flag caused vfio_add_kvm_msi_virq() to become a no-op, meaning the dummy irq would always be delivered via qemu. d1f6af6 changed vfio_add_kvm_msi_virq() so it takes a vector number instead of the msg parameter, and determines the correct message itself. The test for !msg was removed, and not replaced with anything there or in the caller. With an spapr guest which has a VFIO device, if an EEH error occurs on the host hardware, then the device will be isolated then reset. This is a combination of host and guest action, mediated by some EEH related hypercalls. I haven't fully traced the mechanics, but somehow installing the kvm irqchip route for the dummy irq on the BCM5719 means that after EEH reset and recovery, at least some irqs are no longer delivered to the guest. In particular, the guest never gets the link up event, and so the NIC is effectively dead. [1] EEH (Enhanced Error Handling) is an IBM POWER server specific PCI-* error reporting and recovery mechanism. The concept is somewhat similar to PCI-E AER, but the details are different.

2016-09-15virtio-bus: Plug devices after features are negotiatedMaxime Coquelin4-23/+57
Currently, devices are plugged before features are negotiated. If the backend doesn't support VIRTIO_F_VERSION_1, the transport needs to rewind some settings. This is the case for CCW, for which a post_plugged callback had been introduced, where max_rev field is just updated if VIRTIO_F_VERSION_1 is not supported by the backend. For PCI, implementing post_plugged would be much more complicated, so it needs to know whether the backend supports VIRTIO_F_VERSION_1 at plug time. Currently, nothing is done for PCI. Modern capabilities get exposed to the guest even if VIRTIO_F_VERSION_1 is not supported by the backend, which confuses the guest. This patch replaces existing post_plugged solution with an approach that fits with both transports. Features negotiation is performed before ->device_plugged() call. A pre_plugged callback is introduced so that the transports can set their supported features. Cc: Michael S.
