target-i386/cpu: Name new CPUID bits
Update QEMU's knowledge of CPUID bit names. This allows to
enable/disable those new features on QEMU's command line when
using KVM and prepares future feature enablement in QEMU.
This adds F16C, RDRAND, LWP, TBM, TopoExt, PerfCtr_Core, PerfCtr_NB,
FSGSBASE, BMI1, AVX2, BMI2, ERMS, PCID, InvPCID, RTM, RDSeed and ADX.
Sources where the AMD BKDG for Family 15h/Model 10h, Intel Software
Developer Manual, and the Linux kernel for the leaf 7 bits.

target-i386/cpu: Name new CPUID bits
Update QEMU's knowledge of CPUID bit names. This allows to
enable/disable those new features on QEMU's command line when
using KVM and prepares future feature enablement in QEMU.
This adds F16C, RDRAND, LWP, TBM, TopoExt, PerfCtr_Core, PerfCtr_NB,
FSGSBASE, BMI1, AVX2, BMI2, ERMS, PCID, InvPCID, RTM, RDSeed and ADX.
Sources where the AMD BKDG for Family 15h/Model 10h, Intel Software
Developer Manual, and the Linux kernel for the leaf 7 bits.

i386: kvm: filter CPUID feature words earlier, on cpu.c
cpu.c contains the code that will check if all requested CPU features
are available, so the filtering of KVM features must be there, so we can
implement "check" and "enforce" properly.
The only point where kvm_arch_init_vcpu() is called on i386 is:
- cpu_x86_init()
- x86_cpu_realize() (after cpu_x86_register() is called)
- qemu_init_vcpu()
- qemu_kvm_start_vcpu()
- qemu_kvm_thread_fn() (on a new thread)
- kvm_init_vcpu()
- kvm_arch_init_vcpu()
With this patch, the filtering will be done earlier, at:
- cpu_x86_init()
- cpu_x86_register() (before x86_cpu_realize() is called)
Also, the KVM CPUID filtering will now be done at the same place where
the TCG CPUID feature filtering is done. Later, the code can be changed
to use the same filtering code for the "check" and "enforce" modes, as
now the cpu.c code knows exactly which CPU features are going to be
exposed to the guest (and much earlier).
One thing I was worrying about when doing this is that
kvm_arch_get_supported_cpuid() depends on kvm_irqchip_in_kernel(), and
maybe the 'kvm_kernel_irqchip' global variable wasn't initialized yet at
CPU creation time. But kvm_kernel_irqchip is initialized during
kvm_init(), that is called very early (much earlier than the machine
init function), and kvm_init() is already a requirement to run the
GET_SUPPORTED_CPUID ioctl() (as kvm_init() initializes the kvm_state
global variable).
Side note: it would be nice to keep KVM-specific code inside kvm.c. The
problem is that properly implementing -cpu check/enforce code (that's
inside cpu.c) depends directly on the feature bit filtering done using
kvm_arch_get_supported_cpuid(). Currently -cpu check/enforce is broken
because it simply uses the host CPU feature bits instead of
GET_SUPPORTED_CPUID, and we need to fix that.

target-i386: CPUID: return highest basic leaf if eax > cpuid_xlevel
This fixes a subtle bug. A bug that probably won't cause trouble for any
existing OS, but a bug anyway:
Intel SDM Volume 2, CPUID Instruction states:
> Two types of information are returned: basic and extended function
> information. If a value entered for CPUID.EAX is higher than the maximum
> input value for basic or extended function for that processor then the
> data for the highest basic information leaf is returned. For example,
> using the Intel Core i7 processor, the following is true:
>
> CPUID.EAX = 05H (* Returns MONITOR/MWAIT leaf. *)
> CPUID.EAX = 0AH (* Returns Architectural Performance Monitoring leaf. *)
> CPUID.EAX = 0BH (* Returns Extended Topology Enumeration leaf. *)
> CPUID.EAX = 0CH (* INVALID: Returns the same information as CPUID.EAX = 0BH. *)
> CPUID.EAX = 80000008H (* Returns linear/physical address size data. *)
> CPUID.EAX = 8000000AH (* INVALID: Returns same information as CPUID.EAX = 0BH. *)
AMD's CPUID Specification, on the other hand, is less specific:
> The CPUID instruction supports two sets or ranges of functions,
> standard and extended.
>
> • The smallest function number of the standard function range is
> Fn0000_0000. The largest function num- ber of the standard function
> range, for a particular implementation, is returned in CPUID
> Fn0000_0000_EAX.
>
> • The smallest function number of the extended function range is
> Fn8000_0000. The largest function num- ber of the extended function
> range, for a particular implementation, is returned in CPUID
> Fn8000_0000_EAX.
>
> Functions that are neither standard nor extended are undefined and
> should not be relied upon.
QEMU's behavior matched Intel's specification before, but this was
changed by commit b3baa152aaef1905876670590275c2dd0bbb088c. This patch
restores the behavior documented by Intel when cpuid_xlevel2 is 0.
The existing behavior when cpuid_xlevel2 is set (falling back to
level=cpuid_xlevel) is being kept, as I couldn't find any public
documentation on the CPUID 0xC0000000 function range on Centaur CPUs.

Expose CPUID leaf 7 only for -cpu host
Changes v2 -> v3;
- Check for kvm_enabled() before setting cpuid_7_0_ebx_features
Changes v1 -> v2:
- Use kvm_arch_get_supported_cpuid() instead of host_cpuid() on
cpu_x86_fill_host().
We should use GET_SUPPORTED_CPUID for all bits on "-cpu host"
eventually, but I am not changing all the other CPUID leaves because
we may not be able to test such an intrusive change in time for 1.1.
Description of the bug:
Since QEMU 0.15, the CPUID information on CPUID[EAX=7,ECX=0] is being
returned unfiltered to the guest, directly from the GET_SUPPORTED_CPUID
return value.
The problem is that this makes the resulting CPU feature flags
unpredictable and dependent on the host CPU and kernel version. This
breaks live-migration badly if migrating from a host CPU that supports
some features on that CPUID leaf (running a recent kernel) to a kernel
or host CPU that doesn't support it.
Migration also is incorrect (the virtual CPU changes under the guest's
feet) if you migrate in the opposite direction (from an old CPU/kernel
to a new CPU/kernel), but with less serious consequences (guests
normally query CPUID information only once on boot).
Fortunately, the bug affects only users using cpudefs with level >= 7.
The right behavior should be to explicitly enable those features on
[cpudef] config sections or on the "-cpu" command-line arguments. Right
now there is no predefined CPU model on QEMU that has those features:
the latest Intel model we have is Sandy Bridge.
I would like to get this fixed on 1.1, so I am submitting this patch,
that enables those features only if "-cpu host" is being used (as we
don't have any pre-defined CPU model that actually have those features).
After 1.1 is released, we can make those features properly configurable
on [cpudef] and -cpu configuration.
One problem is: with this patch, users with the following setup:
- Running QEMU 1.0;
- Using a cpudef having level >= 7;
- Running a kernel that supports the features on CPUID leaf 7; and
- Running on a CPU that supports some features on CPUID leaf 7
won't be able to live-migrate to QEMU 1.1. But for these users
live-migration is already broken (they can't live-migrate to hosts with
older CPUs or older kernels, already), I don't see how to avoid this
problem.

Expose CPUID leaf 7 only for -cpu host
Changes v2 -> v3;
- Check for kvm_enabled() before setting cpuid_7_0_ebx_features
Changes v1 -> v2:
- Use kvm_arch_get_supported_cpuid() instead of host_cpuid() on
cpu_x86_fill_host().
We should use GET_SUPPORTED_CPUID for all bits on "-cpu host"
eventually, but I am not changing all the other CPUID leaves because
we may not be able to test such an intrusive change in time for 1.1.
Description of the bug:
Since QEMU 0.15, the CPUID information on CPUID[EAX=7,ECX=0] is being
returned unfiltered to the guest, directly from the GET_SUPPORTED_CPUID
return value.
The problem is that this makes the resulting CPU feature flags
unpredictable and dependent on the host CPU and kernel version. This
breaks live-migration badly if migrating from a host CPU that supports
some features on that CPUID leaf (running a recent kernel) to a kernel
or host CPU that doesn't support it.
Migration also is incorrect (the virtual CPU changes under the guest's
feet) if you migrate in the opposite direction (from an old CPU/kernel
to a new CPU/kernel), but with less serious consequences (guests
normally query CPUID information only once on boot).
Fortunately, the bug affects only users using cpudefs with level >= 7.
The right behavior should be to explicitly enable those features on
[cpudef] config sections or on the "-cpu" command-line arguments. Right
now there is no predefined CPU model on QEMU that has those features:
the latest Intel model we have is Sandy Bridge.
I would like to get this fixed on 1.1, so I am submitting this patch,
that enables those features only if "-cpu host" is being used (as we
don't have any pre-defined CPU model that actually have those features).
After 1.1 is released, we can make those features properly configurable
on [cpudef] and -cpu configuration.
One problem is: with this patch, users with the following setup:
- Running QEMU 1.0;
- Using a cpudef having level >= 7;
- Running a kernel that supports the features on CPUID leaf 7; and
- Running on a CPU that supports some features on CPUID leaf 7
won't be able to live-migrate to QEMU 1.1. But for these users
live-migration is already broken (they can't live-migrate to hosts with
older CPUs or older kernels, already), I don't see how to avoid this
problem.
