KVM: SVM: Add new intercept word in vmcb_control_area
The new intercept bits have been added in vmcb control area to support few more interceptions. Here are the some of them. - INTERCEPT_INVLPGB, - INTERCEPT_INVLPGB_ILLEGAL, - INTERCEPT_INVPCID, - INTERCEPT_MCOMMIT, - INTERCEPT_TLBSYNC, Add a new intercept word in vmcb_control_area to support these instructions. Also update kvm_nested_vmrun trace function to support the new addition. AMD documentation for these instructions is available at "AMD64 Architecture Programmer’s Manual Volume 2: System Programming, Pub. 24593 Rev. 3.34(or later)" The documentation can be obtained at the links below: Link: https://www.amd.com/system/files/TechDocs/24593.pdf Link: https://bugzilla.kernel.org/show_bug.cgi?id=206537 Signed-off-by: Babu Moger <babu.moger@amd.com> Reviewed-by: Jim Mattson <jmattson@google.com> Message-Id: <159985251547.11252.16994139329949066945.stgit@bmoger-ubuntu> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
