2012-12-23target-i386: CPUID: return highest basic leaf if eax > cpuid_xlevelEduardo Habkost1-1/+5
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.

2012-12-06target-i386: Separate feature string parsing from CPU model lookupEduardo Habkost1-23/+46
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).

Change the kvm_cpu_fill_host() function to use kvm_arch_get_supported_cpuid() instead of running the CPUID instruction directly, when checking for supported CPUID features. This should solve two problems at the same time: * "-cpu host" was not enabling features that don't need support on the host CPU (e.g. x2apic); * "check" and "enforce" options were not detecting problems when the host CPU did support a feature, but the KVM kernel code didn't support it.

2012-10-30target-i386: cpu: make -cpu host/check/enforce code KVM-specificEduardo Habkost1-7/+18
Rationale: * "-cpu host" is available only when using KVM * The current implementation of -cpu check/enforce (check_features_against_host()) makes sense only when using KVM. So this makes the functions check_features_against_host() and cpu_x86_fill_host() KVM-specific, document them as such, and rename them to kvm_check_features_against_host() and kvm_cpu_fill_host().
