| * Add VHOST_USER_PROTOCOL_F_CONFIGURE_MEM_SLOTSRaphael Norwitz2020-06-121-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change introduces a new feature to the vhost-user protocol allowing a backend device to specify the maximum number of ram slots it supports. At this point, the value returned by the backend will be capped at the maximum number of ram slots which can be supported by vhost-user, which is currently set to 8 because of underlying protocol limitations. The returned value will be stored inside the VhostUserState struct so that on device reconnect we can verify that the ram slot limitation has not decreased since the last time the device connected.

| * virtio-balloon: Provide an interface for free page reportingAlexander Duyck2020-06-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for free page reporting. The idea is to function very similar to how the balloon works in that we basically end up madvising the page as not being used. However we don't really need to bother with any deflate type logic since the page will be faulted back into the guest when it is read or written to. This provides a new way of letting the guest proactively report free pages to the hypervisor, so the hypervisor can reuse them. In contrast to inflate/deflate that is triggered via the hypervisor explicitly.

| * virtio-balloon: Implement support for page poison reporting featureAlexander Duyck2020-06-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to make certain to advertise support for page poison reporting if we want to actually get data on if the guest will be poisoning pages. Add a value for reporting the poison value being used if page poisoning is enabled in the guest. With this we can determine if we will need to skip free page reporting when it is enabled in the future. The value currently has no impact on existing balloon interfaces. In the case of existing balloon interfaces the onus is on the guest driver to reapply whatever poison is in place. When we add free page reporting the poison value is used to determine if we can perform in-place page reporting. The expectation is that a reported page will already contain the value specified by the poison, and the reporting of the page should not change that value.

In such cases, the SRAT needs to have Memory Affinity structures in the SRAT for these NVDIMMs, otherwise Linux doesn't populate node data structures properly during NUMA initialization. See the following for an example failure case. https://lore.kernel.org/linux-nvdimm/20200416225438.15208-1-vishal.l.verma@intel.com/ Introduce a new helper, nvdimm_build_srat(), and call it for both the i386 and arm versions of 'build_srat()' to augment the SRAT with memory affinity information for NVDIMMs. The relevant command line options to exercise this are below. Nodes 0-1 contain CPUs and regular memory, and nodes 2-3 are the NVDIMM address space. -object memory-backend-ram,id=mem0,size=2048M -numa node,nodeid=0,memdev=mem0, -numa cpu,node-id=0,socket-id=0 -object memory-backend-ram,id=mem1,size=2048M -numa node,nodeid=1,memdev=mem1, -numa cpu,node-id=1,socket-id=1 -numa node,nodeid=2, -object memory-backend-file,id=nvmem0,share,mem-path=nvdimm-0,size=16384M,align=1G -device nvdimm,memdev=nvmem0,id=nv0,label-size=2M,node=2 -numa node,nodeid=3, -object memory-backend-file,id=nvmem1,share,mem-path=nvdimm-1,size=16384M,align=1G -device nvdimm,memdev=nvmem1,id=nv1,label-size=2M,node=3 Cc: Jingqi Liu <jingqi.liu@intel.com> Cc: Michael S.

* qdev: Unrealize must not failMarkus Armbruster2020-05-156-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Devices may have component devices and buses. Device realization may fail. Realization is recursive: a device's realize() method realizes its components, and device_set_realized() realizes its buses (which should in turn realize the devices on that bus, except bus_set_realized() doesn't implement that, yet). When realization of a component or bus fails, we need to roll back: unrealize everything we realized so far. If any of these unrealizes failed, the device would be left in an inconsistent state. Must not happen. device_set_realized() lets it happen: it ignores errors in the roll back code starting at label child_realize_fail. Since realization is recursive, unrealization must be recursive, too. But how could a partly failed unrealize be rolled back? We'd have to re-realize, which can fail. This design is fundamentally broken. device_set_realized() does not roll back at all. Instead, it keeps unrealizing, ignoring further errors. It can screw up even for a device with no buses: if the lone dc->unrealize() fails, it still unregisters vmstate, and calls listeners' unrealize() callback. bus_set_realized() does not roll back either. Instead, it stops unrealizing. Fortunately, no unrealize method can fail, as we'll see below. To fix the design error, drop parameter @errp from all the unrealize methods. Any unrealize method that uses @errp now needs an update. This leads us to unrealize() methods that can fail. Merely passing it to another unrealize method cannot cause failure, though. Here are the ones that do other things with @errp: * virtio_serial_device_unrealize() Fails when qbus_set_hotplug_handler() fails, but still does all the other work. On failure, the device would stay realized with its resources completely gone. Oops. Can't happen, because qbus_set_hotplug_handler() can't actually fail here. Pass &error_abort to qbus_set_hotplug_handler() instead. * hw/ppc/spapr_drc.c's unrealize() Fails when object_property_del() fails, but all the other work is already done. On failure, the device would stay realized with its vmstate registration gone. Oops. Can't happen, because object_property_del() can't actually fail here. Pass &error_abort to object_property_del() instead. * spapr_phb_unrealize() Fails and bails out when remove_drcs() fails, but other work is already done. On failure, the device would stay realized with some of its resources gone. Oops. remove_drcs() fails only when chassis_from_bus()'s object_property_get_uint() fails, and it can't here. Pass &error_abort to remove_drcs() instead. Therefore, no unrealize method can fail before this patch. device_set_realized()'s recursive unrealization via bus uses object_property_set_bool(). Can't drop @errp there, so pass &error_abort. We similarly unrealize with object_property_set_bool() elsewhere, always ignoring errors. Pass &error_abort instead. Several unrealize methods no longer handle errors from other unrealize methods: virtio_9p_device_unrealize(), virtio_input_device_unrealize(), scsi_qdev_unrealize(), ... Much of the deleted error handling looks wrong anyway. One unrealize methods no longer ignore such errors: usb_ehci_pci_exit(). Several realize methods no longer ignore errors when rolling back: v9fs_device_realize_common(), pci_qdev_unrealize(), spapr_phb_realize(), usb_qdev_realize(), vfio_ccw_realize(), virtio_device_realize().
