* net/virtio: fix re-plugging of primary deviceJens Freimann2019-11-251-17/+25
| | | | | | | | | | | | | | | failover_replug_primary was returning true on failure which lead to re-plug not working when a migration failed. Fix this by returning success when hotplug worked. This is a bug that was missed in last round of testing but was tested succesfully with this version. Also make sure we don't pass NULL to qdev_set_parent_bus(). This fixes CID 1407224.

* net/virtio: fix dev_unplug_pendingJens Freimann2019-11-251-0/+3
| | | | | | | | | | | | | | | | | | .dev_unplug_pending is set up by virtio-net code indepent of failover support was set for the device or not. This gives a wrong result when we check for existing primary devices in migration code. Fix this by actually calling dev_unplug_pending() instead of just checking if the function pointer was set. When the feature was not negotiated dev_unplug_pending() will always return false. This prevents us from going into the wait-unplug state when there's no primary device present.

* net/cadence_gem: Set PHY autonegotiation restart statusLinus Ziegert2019-11-191-4/+5
| | | | | | | | | | | | | | | | | | | The Linux kernel PHY driver sets AN_RESTART in the BMCR of the PHY when autonegotiation is started. Recently the kernel started to read back the PHY's AN_RESTART bit and now checks whether the autonegotiation is complete and the bit was cleared [1]. Otherwise the link status is down. The emulated PHY needs to clear AN_RESTART immediately to inform the kernel driver about the completion of autonegotiation phase.

* net/virtio: add failover supportJens Freimann2019-10-291-0/+302
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support to handle failover device pairs of a virtio-net device and a (vfio-)pci device, where the virtio-net acts as the standby device and the (vfio-)pci device as the primary. The general idea is that we have a pair of devices, a (vfio-)pci and a emulated (virtio-net) device. Before migration the vfio device is unplugged and data flows to the emulated device, on the target side another (vfio-)pci device is plugged in to take over the data-path. In the guest the net_failover module will pair net devices with the same MAC address. To achieve this we need: 1. Provide a callback function for the should_be_hidden DeviceListener. It is called when the primary device is plugged in. Evaluate the QOpt passed in to check if it is the matching primary device. It returns if the device should be hidden or not. When it should be hidden it stores the device options in the VirtioNet struct and the device is added once the VIRTIO_NET_F_STANDBY feature is negotiated during virtio feature negotiation. If the virtio-net devices are not realized at the time the (vfio-)pci devices are realized, we need to connect the devices later. This way we make sure primary and standby devices can be specified in any order. 2. Register a callback for migration status notifier. When called it will unplug its primary device before the migration happens. 3. Register a callback for the migration code that checks if a device needs to be unplugged from the guest.

* ptimer: Rename ptimer_init() to ptimer_init_with_bh()Peter Maydell2019-10-152-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the ptimer design uses a QEMU bottom-half as its mechanism for calling back into the device model using the ptimer when the timer has expired. Unfortunately this design is fatally flawed, because it means that there is a lag between the ptimer updating its own state and the device callback function updating device state, and guest accesses to device registers between the two can return inconsistent device state. We want to replace the bottom-half design with one where the guest device's callback is called either immediately (when the ptimer triggers by timeout) or when the device model code closes a transaction-begin/end section (when the ptimer triggers because the device model changed the ptimer's count value or other state). As the first step, rename ptimer_init() to ptimer_init_with_bh(), to free up the ptimer_init() name for the new API. We can then convert all the ptimer users away from ptimer_init_with_bh() before removing it entirely. (Commit created with git grep -l ptimer_init | xargs sed -i -e 's/ptimer_init/ptimer_init_with_bh/' and three overlong lines folded by hand.)

| | | | | | | | | | | | | | | | | | | As explained in commit aff39be0ed97: Both functions, object_initialize() and object_property_add_child() increase the reference counter of the new object, so one of the references has to be dropped afterwards to get the reference counting right. Otherwise the child object will not be properly cleaned up when the parent gets destroyed. Thus let's use now object_initialize_child() instead to get the reference counting here right.

| * Set ENET_BD_BDU in I.MX FEC controllerAaron Hill2019-08-161-0/+4

This is done for both transmit and receive descriptors. This allows the QNX 7.0.0 BSP for the Sabrelite board (which can be found at http://blackberry.qnx.com/en/developers/bsp) to properly control the FEC. Without this patch, the BSP ethernet driver will never re-use FEC descriptors, as the unset ENET_BD_BDU flag will cause it to believe that the descriptors are still in use by the NIC. Note that Linux does not appear to use this field at all, and is unaffected by this patch. Without this patch, QNX will think that the NIC is still processing its transaction descriptors, and won't send any more data over the network. For reference: On page 1192 of the I.MX 6DQ reference manual revision (Rev. 5, 06/2018), which can be found at https://www.nxp.com/products/processors-and-microcontrollers/arm-based-processors-and-mcus/i.mx-applications-processors/i.mx-6-processors/i.mx-6quad-processors-high-performance-3d-graphics-hd-video-arm-cortex-a9-core:i.MX6Q?&tab=Documentation_Tab&linkline=Application-Note the 'BDU' field is described as follows for the 'Enhanced transmit buffer descriptor': 'Last buffer descriptor update done.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TYPE_IOMMU_MEMORY_REGION is a direct subtype of TYPE_MEMORY_REGION. Its instance struct is IOMMUMemoryRegion, and its first member is a MemoryRegion. Correct. Its class struct is IOMMUMemoryRegionClass, and its first member is a DeviceClass. Wrong. Messed up when commit 1221a474676 introduced the QOM type. It even included hw/qdev-core.h just for that. TYPE_MEMORY_REGION doesn't bother to define a class struct. This is fine, it simply defaults to its super-type TYPE_OBJECT's class struct ObjectClass. Changing IOMMUMemoryRegionClass's first member's type to ObjectClass would be a minimal fix, if a bit brittle: if TYPE_MEMORY_REGION ever acquired own class struct, we'd have to update IOMMUMemoryRegionClass to use it. Fix it the clean and robust way instead: give TYPE_MEMORY_REGION its own class struct MemoryRegionClass now, and use it for IOMMUMemoryRegionClass's first member. Revert the include of hw/qdev-core.h, and fix the few files that have come to rely on it.

The issue is the PCI configuration space is not being migrated successfully and MSIX remains masked at destination. Remove the migration differentiation between PCI and PCIe since the logic resides now inside VMSTATE_PCI_DEVICE. Remove also the VMXNET3_COMPAT_FLAG_DISABLE_PCIE based differentiation since at 'realize' time is decided if the device is PCI or PCIe, then the above macro is enough. Use the opportunity to move to the standard VMSTATE_MSIX instead of the deprecated SaveVMHandlers.

* xen: Import other xen/io/*.hAnthony PERARD2019-06-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | A Xen public header have been imported into QEMU (by f65eadb639 "xen: import ring.h from xen"), but there are other header that depends on ring.h which come from the system when building QEMU. This patch resolves the issue of having headers from the system importing a different copie of ring.h. This patch is prompt by the build issue described in the previous patch: 'Revert xen/io/ring.h of "Clean up a few header guard symbols"' ring.h and the new imported headers are moved to "include/hw/xen/interface" as those describe interfaces with a guest. The imported headers are cleaned up a bit while importing them: some part of the file that QEMU doesn't use are removed (description of how to make hypercall in grant_table.h have been removed). Other cleanup: - xen-mapcache.c and xen-legacy-backend.c don't need grant_table.h. - xenfb.c doesn't need event_channel.h.
