* typedefs: add QJSONGreg Kurz2018-06-151-2/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 83ee768d6247b, we now have two places that define the QJSON type: $ git grep 'typedef struct QJSON QJSON' include/migration/vmstate.h:typedef struct QJSON QJSON; migration/qjson.h:typedef struct QJSON QJSON; This breaks docker-test-build@centos6: In file included from /tmp/qemu-test/src/migration/savevm.c:59: /tmp/qemu-test/src/migration/qjson.h:16: error: redefinition of typedef 'QJSON' /tmp/qemu-test/src/include/migration/vmstate.h:30: note: previous declaration of 'QJSON' was here make: *** [migration/savevm.o] Error 1 This happens because CentOS 6 has an old GCC 4.4.7. Even if redefining a typedef with the same type is permitted since GCC 4.6, unless -pedantic is passed, we don't really need to do that on purpose. Let's have a single definition in <qemu/typedefs.h> instead.

* Include less of the generated modular QAPI headersMarkus Armbruster2018-03-023-2/+3
| | | | | | | | | | | | | | | | | | | | | In my "build everything" tree, a change to the types in qapi-schema.json triggers a recompile of about 4800 out of 5100 objects. The previous commit split up qmp-commands.h, qmp-event.h, qmp-visit.h, qapi-types.h. Each of these headers still includes all its shards. Reduce compile time by including just the shards we actually need. To illustrate the benefits: adding a type to qapi/migration.json now recompiles some 2300 instead of 4800 objects. The next commit will improve it further.

| * pci/bus: let it has higher migration priorityPeter Xu2018-02-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the past, we prioritized IOMMU migration so that we have such a priority order: IOMMU > PCI Devices When migrating a guest with both vIOMMU and a pcie-root-port, we'll always migrate vIOMMU first, since pci buses will be seen to have the same priority of general PCI devices. That's problematic. The thing is that PCI bus number information is stored in the root port, and that is needed by vIOMMU during post_load(), e.g., to figure out context entry for a device. If we don't have correct bus numbers for devices, we won't be able to recover device state of the DMAR memory regions, and things will be messed up. So let's boost the PCIe root ports to be even with higher priority: PCIe Root Port > IOMMU > PCI Devices A smoke test shows that this patch fixes bug 1538953. Also, apply this rule to all the PCI bus/bridge devices: ioh3420, xio3130_downstream, xio3130_upstream, pcie_pci_bridge, pci-pci bridge, i82801b11. I noted that we set pcie_pci_bridge_dev_vmstate twice. Clean that up together. CC: Alex Williamson <alex.williamson@redhat.com> CC: Marcel Apfelbaum <marcel@redhat.com> CC: Michael S.

* migration: move only_migratable to MigrationStatePeter Xu2017-06-281-0/+2
| | | | | | | | | | | | | | | | | | One less global variable, and it does only matter with migration. We keep the old "--only-migratable" option, but also now we support: -global migration.only-migratable=true Currently still keep the old interface. Hmm, now vl.c has no way to access migrate_get_current(). Export a function for it to setup only_migratable.

| | | | | | | | | | | | | Put it into MigrationState then we can use the properties to specify whether to enable storing global state. Removing global_state_set_optional() since now we can use HW_COMPAT_2_3 for x86/power, and AccelClass.global_props for Xen.

* migration: let MigrationState be a qdevPeter Xu2017-06-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | | Let the old man "MigrationState" join the object family. Direct benefit is that we can start to use all the property features derived from current QDev, like: HW_COMPAT_* bits, command line setup for migration parameters (so will never need to set them up each time using HMP/QMP, this is really, really attractive for test writters), etc. I see no reason to disallow this happen yet. So let's start from this one, to see whether it would be anything good. Now we init the MigrationState struct statically in main() to make sure it's initialized after global properties are applied, since we'll use them during creation of the object. No functional change at all.
