Hi Avi, Hi Marcelo, here is a patch-set which adds support for VMCB state caching to KVM. This is a new CPU feature where software can mark certain parts of the VMCB as unchanged since the last vmexit and the hardware can then avoid reloading these parts from memory. The feature is implemented downwards-compatible in hardware, so a 0-bit means the state has changed and needs to be reloaded. This makes it possible to implement the bits without checking for the feature, as done in this patch-set (another reason is that the check is as expensive as clearing the bit). Processors which do not implement VMCB state caching just ignore these bits. These patches were tested with multiple guests (Windows, Linux, also in parallel) and also with nested-svm. The patches apply on-top of the intercept mask wrapping patch-set I sent earlier this week. Your feedback is appreciated.
