Andrey Smetanin ff99aa64b1 target-i386/kvm: Hyper-V SynIC timers MSR's support
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.

Andrey Smetanin 866eea9a13 target-i386/kvm: Hyper-V SynIC MSR's support
This patch does Hyper-V Synthetic interrupt
controller(Hyper-V SynIC) MSR's support and
migration. Hyper-V SynIC is enabled by cpu's
'hv-synic' option.

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

Changes v3:
* removed 'msr_hv_synic_version' migration because
it's value always the same
* moved SynIC msr's initialization into kvm_arch_init_vcpu

Alex Williamson 1c4a55dbed kvm: Allow the Hyper-V vendor ID to be specified
According to Microsoft documentation, the signature in the standard
hypervisor CPUID leaf at 0x40000000 identifies the Vendor ID and is
for reporting and diagnostic purposes only.  We can therefore allow
the user to change it to whatever they want, within the 12 character
limit.  Add a new hv-vendor-id option to the -cpu flag to allow
for this, ex:

 -cpu host,hv_time,hv-vendor-id=KeenlyKVM

Eduardo Habkost 4d1b279b06 target-i386: Support migratable=no properly
When the "migratable" property was implemented, the behavior was tested
by changing the default on the code, but actually using the option on
the command-line (e.g. "-cpu host,migratable=false") doesn't work as
expected. This is a regression for a common use case of "-cpu host",
which is to enable features that are supported by the host CPU + kernel
before feature-specific code is added to QEMU.

Fix this by initializing the feature words for "-cpu host" on
x86_cpu_parse_featurestr(), right after parsing the CPU options.

Eduardo Habkost 84f1b92f97 target-i386: Add "migratable" property to "host" CPU model
This flag will allow the user to choose between two modes:
 * All flags that can be enabled on the host, even if unmigratable
   (migratable=no);
 * All flags that can be enabled on the host, are known to QEMU
   and migratable (migratable=yes).

The default is still migratable=false, to keep current behavior, but
this will be changed to migratable=true by another patch.

My plan was to support the "migratable" flag on all CPU classes, but
have the default to "false" on all CPU models except "host". However,
DeviceClass has no mechanism to allow a child class to have a different
property default from the parent class yet, so by now only the "host"
CPU model will support the "migratable" flag.

Alex Williamson f522d2acc5 kvm: Enable -cpu option to hide KVM
The latest Nvidia driver (337.88) specifically checks for KVM as the
hypervisor and reports Code 43 for the driver in a Windows guest when
found.  Removing or changing the KVM signature is sufficient for the
driver to load and work.  This patch adds an option to easily allow
the KVM hypervisor signature to be hidden using '-cpu kvm=off'.  We
continue to expose KVM via the cpuid value by default.  The state of
this option does not supercede or replace -enable-kvm or the accel=kvm
machine option.  This only changes the visibility of KVM to the guest
and paravirtual features specifically tied to the KVM cpuid.

Eduardo Habkost d940ee9b78 target-i386: X86CPU model subclasses
Register separate QOM types for each x86 CPU model.

This will allow management code to more easily probe what each CPU model
provides, by simply creating objects using the appropriate class name,
without having to restart QEMU.

This also allows us to eliminate the qdev_prop_set_globals_for_type()
hack to set CPU-model-specific global properties.

Instead of creating separate class_init functions for each class, I just
used class_data to store a pointer to the X86CPUDefinition struct for
each CPU model. This should make the patch shorter and easier to review.
Later we can gradually convert each X86CPUDefinition field to lists of
per-class property defaults.

The "host" CPU model is special, as the feature flags depend on KVM
being initialized. So it has its own class_init and instance_init
function, and feature flags are set on instance_init instead of
class_init.

Eduardo Habkost 9337e3b6e1 target-i386: Disable PMU CPUID leaf by default
Bug description: QEMU currently gets all bits from GET_SUPPORTED_CPUID
for CPUID leaf 0xA and passes them directly to the guest. This makes
the guest ABI depend on host kernel and host CPU capabilities, and
breaks live migration if we migrate between hosts with different
capabilities (e.g., different number of PMU counters).

Add a "pmu" property to X86CPU, and set it to true only on "-cpu host",
or on pc-*-1.5 and older machine-types.

For now, setting pmu=on will enable the current passthrough mode that
doesn't have any ABI stability guarantees, but in the future we may
implement a mode where the PMU CPUID bits are stable and configurable.

Andreas Färber 7a05995361 target-i386: Defer MCE init
Commit de024815e3 (target-i386: QOM'ify
CPU init) moved mce_init() call from helper.c:cpu_x86_init() into
X86CPU's cpu.c:x86_cpu_initfn().
mce_init() checks for a family >= 6 though, so we could end up with a
sequence such as for -cpu somecpu,family=6:

  x86_cpu_initfn => X86CPU::family == 5
    mce_init => no-op
  cpu_x86_register => X86CPU::family = 6
  => MCE unexpectedly not init'ed

or for -cpu someothercpu,family=5:

  x86_cpu_initfn => X86CPU::family == 6
    mce_init => init'ed
  cpu_x86_register => X86CPU::family = 5
  => MCE unexpectedly init'ed

Therefore partially revert the above commit. To avoid moving
mce_init() back into helper.c, foresightedly move it into a
new x86_cpu_realize() function and, in lack of ObjectClass::realize,
call it directly from cpu_x86_init().

While at it, move the qemu_init_vcpu() call that used to follow
mce_init() in cpu_x86_init() into the new realizefn as well.

Andreas Färber 5fd2087a1b target-i386: QOM'ify CPU
Embed CPUX86State as first member of X86CPU.
Distinguish between "x86_64-cpu" and "i386-cpu".
Drop cpu_x86_close() in favor of calling object_delete() directly.

For now let CPUClass::reset() call cpu_state_reset().
