Laszlo Ersek 56c4bfb3f0 dump: rebase from host-private RAMBlock offsets to guest-physical addresses
RAMBlock.offset                   --> GuestPhysBlock.target_start
RAMBlock.offset + RAMBlock.length --> GuestPhysBlock.target_end
RAMBlock.length                   --> GuestPhysBlock.target_end -
                                      GuestPhysBlock.target_start

"GuestPhysBlock.host_addr" is only used when writing the dump contents.

This patch enables "crash" to work with the vmcore by rebasing the vmcore
from the left side of the following diagram to the right side:

Andreas Färber cd7b87ffe9 target-i386: Fix X86CPU error handling
Error **errp argument is not for emitting warnings, it means an error
has occurred and the caller should not make any assumptions about the
state of other return values (unless otherwise documented).

Therefore cpu_x86_create() must unref the new X86CPU itself, and
pc_new_cpu() must check for an Error rather than NULL return value.

While at it, clean up a superfluous NULL check.

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 14a10fc399 cpu: Partially revert "cpu: Change qemu_init_vcpu() argument to CPUState"
Commit c643bed99 moved qemu_init_vcpu() calls to common CPUState code.
This causes x86 cpu-add to fail with "KVM: setting VAPIC address failed".

The reason for the failure is that CPUClass::kvm_fd is not yet
initialized in the following call graph:
->x86_cpu_realizefn
 ->x86_cpu_apic_realize
  ->qdev_init
   ->device_set_realized
    ->device_reset (hotplugged == 1)
     ->apic_reset_common
      ->vapic_base_update
       ->kvm_apic_vapic_base_update
This causes attempted KVM vCPU ioctls to fail.

By contrast, in the non-hotplug case the APIC is reset much later, when
the vCPU is already initialized.

As a quick and safe solution, move the qemu_init_vcpu() call back into
the targets' realize functions.

This will allow migration from older KVM on host without unrestricted guest

For example migration from a Penryn host (with kernel 2.6.32) to
a Westmere host (for real mode guest) will fail with "kvm: unhandled exit 80000021".

A transition from CPUFooState to FooCPU can be considered safe,
just like FooCPU::env access in the opposite direction.
The only benefit of the FOO_CPU() casts would be protection against
bogus CPUFooState pointers, but then surrounding code would likely
break, too.

This should slightly improve interrupt etc. performance when going from
CPUFooState to FooCPU.

Markus Armbruster 36ad0e948e Fix -machine options accel, kernel_irqchip, kvm_shadow_mem
Multiple -machine options with the same ID are merged.  All but the
one without an ID are to be silently ignored.

In most places, we query these options with a null ID.  This is
correct.

In some places, we instead query whatever options come first in the
list.  This is wrong.  When the -machine processed first happens to
have an ID, options are taken from that ID, and the ones specified
without ID are silently ignored.

Example:

    $ upstream-qemu -nodefaults -S -display none -monitor stdio -machine id=foo -machine accel=kvm,usb=on
    $ upstream-qemu -nodefaults -S -display none -monitor stdio -machine id=foo,accel=kvm,usb=on -machine accel=xen
    $ upstream-qemu -nodefaults -S -display none -monitor stdio -machine accel=xen -machine id=foo,accel=kvm,usb=on

    $ qemu-system-x86_64 -nodefaults -S -display none -monitor stdio -machine accel=kvm,usb=on

Option usb is queried correctly, and the one without an ID wins,
regardless of option order.

Option accel is queried incorrectly, and which one wins depends on
option order and ID.

Affected options are accel (and its sugared forms -enable-kvm and
-no-kvm), kernel_irqchip, kvm_shadow_mem.

Additionally, option kernel_irqchip is normally on by default, except
it's off when no -machine options are given.  Bug can't bite, because
kernel_irqchip is used only when KVM is enabled, KVM is off by
default, and enabling always creates -machine options.  Downstreams
that enable KVM by default do get bitten, though.

Use qemu_get_machine_opts() to fix these bugs.
