KVM: SVM: Add new intercept word in vmcb_control_area

2020-09-28T11:57:15Z

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 Reviewed-by: Jim Mattson Message-Id: <159985251547.11252.16994139329949066945.stgit@bmoger-ubuntu> Signed-off-by: Paolo Bonzini

KVM: SVM: Modify 64 bit intercept field to two 32 bit vectors

2020-09-28T11:57:15Z

Convert all the intercepts to one array of 32 bit vectors in vmcb_control_area. This makes it easy for future intercept vector additions. Also update trace functions.

KVM: SVM: Introduce vmcb_(set_intercept/clr_intercept/_is_intercept)

2020-09-28T11:57:13Z

This is in preparation for the future intercept vector additions. Add new functions vmcb_set_intercept, vmcb_clr_intercept and vmcb_is_intercept using kernel APIs __set_bit, __clear_bit and test_bit espectively.

KVM: SVM: Add GHCB Accessor functions

2020-09-07T17:45:24Z

Building a correct GHCB for the hypervisor requires setting valid bits in the GHCB. Simplify that process by providing accessor functions to set values and to update the valid bitmap and to check the valid bitmap in KVM.
