Hyper-V SynIC timers are host timers that are configurable by guest through corresponding MSR's (HV_X64_MSR_STIMER*). Guest setup and use fired by host events(SynIC interrupt and appropriate timer expiration message) as guest clock events. The state of Hyper-V SynIC timers are stored in corresponding MSR's. This patch seria implements such MSR's support and migration.

This patch does not allow cpu creation if 'hv-synic' option specified but kernel doesn't support Hyper-V SynIC.

KVM can't virtualize rdtscp on AMD CPUs yet, so there's no point in enabling it by default on AMD CPU models, as all we are getting are confused users because of the "host doesn't support requested feature" warnings.

Current default behavior of QEMU is to silently disable features that are not supported by the host when a CPU model is requested in the command-line. This means that in addition to risking breaking guest ABI by default, we are silent about it. I would like to enable "enforce" by default, but this can easily break existing production systems because of the way libvirt makes assumptions about CPU models today (this will change in the future, once QEMU provide a proper interface for checking if a CPU model is runnable). But there's no reason we should be silent about it. So, change target-i386 to enable "check" mode by default so at least we have some warning printed to stderr (and hopefully logged somewhere) when QEMU disables a feature that is not supported by the host system.

Several devices don't survive object_unref(object_new(T)): they crash or hang during cleanup, or they leave dangling pointers behind. This breaks at least device-list-properties, because qmp_device_list_properties() needs to create a device to find its properties. Broken in commit f4eb32b5 "qmp: show QOM properties in device-list-properties", v2.1. Example reproducer: $ qemu-system-aarch64 -nodefaults -display none -machine none -S -qmp stdio {"QMP": {"version": {"qemu": {"micro": 50, "minor": 4, "major": 2}, "package": ""}, "capabilities": []}} { "execute": "qmp_capabilities" } {"return": {}} { "execute": "device-list-properties", "arguments": { "typename": "pxa2xx-pcmcia" } } qemu-system-aarch64: /home/armbru/work/qemu/memory.c:1307: memory_region_finalize: Assertion `((&mr->subregions)->tqh_first == ((void *)0))' failed. Aborted (core dumped) [Exit 134 (SIGABRT)] Unfortunately, I can't fix the problems in these devices right now. Instead, add DeviceClass member cannot_destroy_with_object_finalize_yet to mark them: * Hang during cleanup (didn't debug, so I can't say why): "realview_pci", "versatile_pci". * Dangling pointer in cpus: most CPUs, plus "allwinner-a10", "digic", "fsl,imx25", "fsl,imx31", "xlnx,zynqmp", because they create such CPUs * Assert kvm_enabled(): "host-x86_64-cpu", host-i386-cpu", "host-powerpc64-cpu", "host-embedded-powerpc-cpu", "host-powerpc-cpu" (the powerpc ones can't currently reach the assertion, because the CPUs are only registered when KVM is enabled, but the assertion is arguably in the wrong place all the same) Make qmp_device_list_properties() fail cleanly when the device is so marked. This improves device-list-properties from "crashes, hangs or leaves dangling pointers behind" to "fails". Not a complete fix, just a better-than-nothing work-around. In the above reproducer, device-list-properties now fails with "Can't list properties of device 'pxa2xx-pcmcia'". This also protects -device FOO,help, which uses the same machinery since commit ef523587 "qdev-monitor: include QOM properties in -device FOO, help output", v2.2.

Intel considers POPCNT as part of SSE4.2, and LZCNT as part of BMI1, but Intel also uses AMD's ABM flag to indicate support for both POPCNT and LZCNT. It has to be added to Haswell and Broadwell because Haswell, by adding LZCNT, has completed the ABM.
