[PATCH 0/6] Support for new CPU model SapphireRapids

Posted by Wang, Lei 1 year, 6 months ago

This series aims to add a new CPU model SapphireRapids, and tries to
address the problem stated in
https://lore.kernel.org/all/20220812055751.14553-1-lei4.wang@intel.com/T/#mcf67dbd1ad37c65d7988c36a2b267be9afd2fb30,
so that named CPU model can define its own AMX values, and QEMU won't
pass the wrong AMX values to KVM in future platforms if they have
different values supported.

The original patch is
https://lore.kernel.org/all/20220812055751.14553-1-lei4.wang@intel.com/T/#u.

Wang, Lei (6):
  i386: Introduce FeatureWordInfo for AMX CPUID leaf 0x1D and 0x1E
  i386: Remove unused parameter "uint32_t bit" in
    feature_word_description()
  i386: Introduce new struct "MultiBitFeatureInfo" for multi-bit
    features
  i386: Mask and report unavailable multi-bit feature values
  i386: Initialize AMX CPUID leaves with corresponding env->features[]
