6ad53bdf58 target-i386: fix bits 39:32 of the final physical address when using 4M page
((pde & 0x1fe000) << 19) is the bits 39:32 of the final physical address, and
we shouldn't use unit32_t to calculate it. Convert the type to hwaddr to fix
this problem.

ext2_features for AMD based CPU at realize() time will keep

e8beac00bd target-i386: check/enforce: Eliminate check_feat field
Now that all entries have check_feat=~0 in
kvm_check_features_against_host(), we can eliminate check_feat entirely
and make the code check all bits.

This patch shouldn't introduce any behavior change, as check_feat is set

396d2cfccd target-i386: check/enforce: Check SVM flag support as well
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.

227146259e target-i386: check/enforce: Check all CPUID.80000001H.EDX bits
I have no idea why PPRO_FEATURES was being ignored on the check of the
CPUID.80000001H.EDX bits. I believe it was a mistake, and it was
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
from CPUID.01H.EDX), so we can make the code check/enforce all the
CPUID.80000001H.EDX bits.

8b4beddc6b target-i386: check/enforce: Fix CPUID leaf numbers on error messages
The -cpu check/enforce warnings are printing incorrect information about the
missing flags. There are no feature flags on CPUID leaves 0 and 0x80000000, but
there were references to 0 and 0x80000000 in the table at
kvm_check_features_against_host().

This changes the model_features_t struct to contain the register number as
well, so the error messages print the correct CPUID leaf+register information,
instead of wrong CPUID leaf numbers.

This also changes the format of the error messages, so they follow the
"CPUID.<leaf>.<register>.<name> [bit <offset>]" convention used in Intel
documentation. Example output:

bd004beff8 target-i386: kvm: Enable all supported KVM features for -cpu host
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

refuse to start if kvm_pv_eoi is not supported by the host (after we fix
kvm_check_features_against_host() to check KVM flags as well).

fcb93c0360 target-i386: kvm: -cpu host: Use GET_SUPPORTED_CPUID for SVM features
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
as well).

57f26ae729 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 b3baa152aa. 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.

f28558d3d3 target-i386: Enabling IA32_TSC_ADJUST for QEMU KVM guest VMs
CPUID.7.0.EBX[1]=1 indicates IA32_TSC_ADJUST MSR 0x3b is supported

Basic design is to emulate the MSR by allowing reads and writes to the
hypervisor vcpu specific locations to store the value of the emulated MSRs.
In this way the IA32_TSC_ADJUST value will be included in all reads to
the TSC MSR whether through rdmsr or rdtsc.

As this is a new MSR that the guest may access and modify its value needs
to be migrated along with the other MRSs. The changes here are specifically
for recognizing when IA32_TSC_ADJUST is enabled in CPUID and code added
for migrating its value.

8f961357d0 target-i386: Separate feature string parsing from CPU model lookup
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
lookup code as-is).

features present on the SandyBridge model, but I have removed the SEP and
RDTSCP features from the feature list by mistake. This patch adds the
missing SEP and RDTSCP features (that are present on SandyBridge) to
Haswell.

021941b9d9 target-i386/cpu: Add new Opteron CPU model
Add a new base CPU model called Opteron_G5 to model the latest
Opteron CPUs. This increases the model value and model numbers and
adds TBM, F16C and FMA over the latest G4 model.

c8acc380be 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.
