This patch implements VMRUN. VMRUN enters a virtual CPU and runs that in the same context as the normal guest CPU would run. So basically it is implemented the same way, a normal CPU would do it. We also prepare all intercepts that get OR'ed with the original intercepts, as we do not allow a level 2 guest to be intercepted less than the first level guest. v2 implements the following improvements: - fixes the CPL check - does not allocate iopm when not used - remembers the host's IF in the HIF bit in the hflags v3: - make use of the new permission checking - add support for V_INTR_MASKING_MASK v4: - use host page backed hsave v5: - remove IOPM merging code v6: - save cr4 so PAE l1 guests work v7: - return 0 on vmrun so we check the MSRs too - fix MSR check to use the correct variable Acked-by: Joerg Roedel <joro@8bytes.org> Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Avi Kivity <avi@redhat.com> |
