Eduardo Habkost 1f43571604 pc: Use "min-[x]level" on compat_props ... Since the automatic cpuid-level code was introduced in commit c39c0edf9b ("target-i386: Automatically set level/xlevel/xlevel2 when needed"), the CPU model tables just define the default CPUID level code (set using "min-level"). Setting "[x]level" forces CPUID level to a specific value and disable the automatic-level logic. But the PC compat code was not updated and the existing "[x]level" compat properties broke compatibility for people using features that triggered the auto-level code. To keep previous behavior, we should set "min-[x]level" instead of "[x]level" on compat_props. This was not a problem for most cases, because old machine-types don't have full-cpuid-auto-level enabled. The only common use case it broke was the CPUID[7] auto-level code, that was already enabled since the first CPUID[7] feature was introduced (in QEMU 1.4.0). This causes the regression reported at: https://bugzilla.redhat.com/show_bug.cgi?id=1454641 Change the PC compat code to use "min-[x]level" instead of "[x]level" on compat_props, and add new test cases to ensure we don't break this again.
