From: Tao Su <tao1...@linux.intel.com>If FEAT_7_1_EAX is 0 and FEAT_7_1_EDX is non-zero, as is the case with a Granite Rapids host and '-cpu host,-avx-vnni,-avx512-bf16,-fzrm,-fsrs,-fsrc,-amx-fp16', we can't get CPUID_7_1 leaf even though CPUID_7_1_EDX has non-zero value. Update cpuid_level_func7 according to CPUID_7_1_EDX, otherwise guest may report wrong maximum number sub-leaves in leaf 07H. Fixes: eaaa197d5b11 ("target/i386: Add support for AVX-VNNI-INT8 in CPUID enumeration") Cc: qemu-sta...@nongnu.org
This patch is not applicable for any stable qemu releases, since the commit it fixes (eaaa197d5b11, which also introduced FEAT_7_1_EDX) is not in any released version, it is v8.0.0-290-geaaa197d5b. This is just for the information (I'm not picking it up for stable), there's nothing wrong with it tagged for stable initially. Thanks! /mjt
