When nested SVM is supported, the kernel returns the SVM flag on
GET_SUPPORTED_CPUID[1], so we can check the SVM flag safely in
kvm_check_features_against_host().
I don't know why the original code ignored the SVM flag. Maybe it was
because kvm_cpu_fill_host() used the CPUID instruction directly instead
of GET_SUPPORTED_CPUID
[1] Older kernels (before v2.6.37) returned the SVM flag even if nested
SVM was _not_ supported. So the only cases where this patch should
change behavior is when SVM is being requested by the user or the
CPU model, but not supported by the host. And on these cases we
really want QEMU to abort if the "enforce" option is set.

I have no idea why PPRO_FEATURES was being ignored on the check of the

supposed to be ~(PPRO_FEATURES & CPUID_EXT2_AMD_ALIASES) or just
~CPUID_EXT2_AMD_ALIASES, because some time ago kvm_cpu_fill_host() used
the CPUID instruction directly (instead of
kvm_arch_get_supported_cpuid()).
But now kvm_cpu_fill_host() uses kvm_arch_get_supported_cpuid(), and
kvm_arch_get_supported_cpuid() returns all supported bits for
CPUID.80000001H.EDX, even the AMD aliases (that are explicitly copied

The -cpu check/enforce warnings are printing incorrect information about the

When using -cpu host, we don't need to use the kvm_default_features
variable, as the user is explicitly asking QEMU to enable all feature
supported by the host.
This changes the kvm_cpu_fill_host() code to use GET_SUPPORTED_CPUID to
initialize the kvm_features field, so we get all host KVM features
enabled.
This will also allow us to properly check/enforce KVM features inside
kvm_check_features_against_host() later. For example, we will be able to
make this:
$ qemu-system-x86_64 -cpu ...,+kvm_pv_eoi,enforce

The existing -cpu host code simply sets every bit inside svm_features
(initializing it to -1), and that makes it impossible to make the
enforce/check options work properly when the user asks for SVM features
explicitly in the command-line.
So, instead of initializing svm_features to -1, use GET_SUPPORTED_CPUID
to fill only the bits that are supported by the host (just like we do
for all other CPUID feature words inside kvm_cpu_fill_host()).
This will keep the existing behavior (as filter_features_for_kvm()
already uses GET_SUPPORTED_CPUID to filter svm_features), but will allow
us to properly check for KVM features inside
kvm_check_features_against_host() later.
For example, we will be able to make this:
$ qemu-system-x86_64 -cpu ...,+pfthreshold,enforce
refuse to start if the SVM "pfthreshold" feature is not supported by the
host (after we fix kvm_check_features_against_host() to check SVM flags

Instead of parsing the whole cpu_model string inside
cpu_x86_find_by_name(), first split it into the CPU model name and the
full feature string, then parse the feature string into pieces.
When using CPU model classes, those two pieces of information will be
used at different moments (CPU model name will be used to find CPU
class, feature string will be used after CPU object was created), so
making the split in two steps will make it easier to refactor the code
later.
This should also help on the CPU properties work, that will just need to
replace the cpu_x86_parse_featurestr() logic (and can keep the CPU model

This should solve two problems at the same time:
* "-cpu host" was not enabling features that don't need support on

cpu_x86_fill_host() KVM-specific, document them as such, and rename them

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.
