[PATCH 0/4] Enable VMM userspace support for CET virtualization

Posted by Yang Weijiang 1 year ago

These are VMM userspace enabling patches for CET virtualization.
Currently CET user mode SHSTK/IBT and kernel mode IBT are supported.
supervisor SHSTK are not supported now, so related MSRs support
are not included in this series.

Yang Weijiang (4):
  target/i386: Enable XSAVES support for user mode CET states
  target/i386: Add CET MSRs access interfaces
  target/i386: Enable CET states migration
  target/i386: Advertise CET flags in feature words
