      KVM: x86: Inject #UD on emulated XSETBV if XSAVES isn't enabled · 50b2d49b
      Sean Christopherson authored
      Inject #UD when emulating XSETBV if CR4.OSXSAVE is not set.  This also
      covers the "XSAVE not supported" check, as setting CR4.OSXSAVE=1 #GPs if
      XSAVE is not supported (and userspace gets to keep the pieces if it
      forces incoherent vCPU state).
      
      Add a comment to kvm_emulate_xsetbv() to call out that the CPU checks
      CR4.OSXSAVE before checking for intercepts.  AMD'S APM implies that #UD
      has priority (says that intercepts are checked before #GP exceptions),
      while Intel's SDM says nothing about interception priority.  However,
      testing on hardware shows that both AMD and Intel CPUs prioritize the #UD
      over interception.
