From 0514ef2fbb3882afe410ba7800c79fd0ef5dbf00 Mon Sep 17 00:00:00 2001 From: Eduardo Habkost Date: Mon, 22 Apr 2013 16:00:15 -0300 Subject: target-i386: Replace cpuid_*features fields with a feature word array MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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 Reviewed-by: Igor Mammedov Signed-off-by: Andreas Färber --- target-i386/helper.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'target-i386/helper.c') diff --git a/target-i386/helper.c b/target-i386/helper.c index 282494fcad..158710a89c 100644 --- a/target-i386/helper.c +++ b/target-i386/helper.c @@ -463,7 +463,7 @@ void cpu_x86_update_cr4(CPUX86State *env, uint32_t new_cr4) tlb_flush(env, 1); } /* SSE handling */ - if (!(env->cpuid_features & CPUID_SSE)) { + if (!(env->features[FEAT_1_EDX] & CPUID_SSE)) { new_cr4 &= ~CR4_OSFXSR_MASK; } env->hflags &= ~HF_OSFXSR_MASK; @@ -471,7 +471,7 @@ void cpu_x86_update_cr4(CPUX86State *env, uint32_t new_cr4) env->hflags |= HF_OSFXSR_MASK; } - if (!(env->cpuid_7_0_ebx_features & CPUID_7_0_EBX_SMAP)) { + if (!(env->features[FEAT_7_0_EBX] & CPUID_7_0_EBX_SMAP)) { new_cr4 &= ~CR4_SMAP_MASK; } env->hflags &= ~HF_SMAP_MASK; -- cgit v1.2.3
