[PATCH 0/2] KVM: SVM: Align SVM with APM defined behaviors

Posted by Kevin Cheng 1 month ago

The APM lists the following behaviors
  - The VMRUN, VMLOAD, VMSAVE, CLGI, VMMCALL, and INVLPGA instructions
    can be used when the EFER.SVME is set to 1; otherwise, these
    instructions generate a #UD exception.
  - If VMMCALL instruction is not intercepted, the instruction raises a
    #UD exception.

The patches in this series fix current SVM bugs that do not adhere to
the APM listed behaviors.

Kevin Cheng (2):
  KVM: SVM: Generate #UD for certain instructions when SVME.EFER is
    disabled
  KVM: SVM: Raise #UD if VMMCALL instruction is not intercepted
