[PATCH 0/2] i386/cpuid: Minor fixes for CPUID leaf 1f setup

Posted by Xiaoyao Li 3 years, 7 months ago

The issue that fixed by Patch 1 looks fatal though it doesn't appear on
KVM because KVM always searches with assending order and hit with the
correct cpuid leaf 0.

Patch 2 removes the wrong constraint on CPUID leaf 1f

Xiaoyao Li (2):
  i386/cpuid: Decrease cpuid_i when skipping CPUID leaf 1F
  i386/cpuid: Remove subleaf constraint on CPUID leaf 1F

ping it one more time.

Does it need a rebase and resend?
