2014-03-13cpu: Move breakpoints field from CPU_COMMON to CPUStateAndreas Färber1-1/+2
Most targets were using offsetof(CPUFooState, breakpoints) to determine how much of CPUFooState to clear on reset. Use the next field after CPU_COMMON instead, if any, or sizeof(CPUFooState) otherwise. Signed-off-by: Andreas Färber <afaerber@suse.de>

2014-03-13cpu: Turn cpu_handle_mmu_fault() into a CPUClass hookAndreas Färber1-2/+1
Note that while such functions may exist both for *-user and softmmu, only *-user uses the CPUState hook, while softmmu reuses the prototype for calling it directly. Signed-off-by: Andreas Färber <afaerber@suse.de>

2013-05-02target-i386: Replace cpuid_*features fields with a feature word arrayEduardo Habkost1-10/+1
This replaces the feature-bit fields on both X86CPU and x86_def_t structs with an array. With this, we will be able to simplify code that simply does the same operation on all feature words (e.g. kvm_check_features_against_host(), filter_features_for_kvm(), add_flagname_to_bitmaps(), CPU feature-bit property lookup/registration, and the proposed "feature-words" property) The following field replacements were made on X86CPU and x86_def_t: (cpuid_)features -> features[FEAT_1_EDX] (cpuid_)ext_features -> features[FEAT_1_ECX] (cpuid_)ext2_features -> features[FEAT_8000_0001_EDX] (cpuid_)ext3_features -> features[FEAT_8000_0001_ECX] (cpuid_)ext4_features -> features[FEAT_C000_0001_EDX] (cpuid_)kvm_features -> features[FEAT_KVM] (cpuid_)svm_features -> features[FEAT_SVM] (cpuid_)7_0_ebx_features -> features[FEAT_7_0_EBX] Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Reviewed-by: Igor Mammedov <imammedo@redhat.com> Signed-off-by: Andreas Färber <afaerber@suse.de>
