I am merging the code in order to start making shortcuts between VMX emulation and SVM emulation. Of course SVM emulation is incomplete, completely untested and not expected to work. But someone could already take a look one the code and give some suggestions. Also looking for anybody with existing SVM kernels - as simple as possible - for testing. Status: - exceptions intercept is not implemented yet - IO intercept is not implemented yet - MSR intercept is not implemented yet - virtual interrupts are not implemented yet - CPUID is not implemented yet No advanced SVM featurez planned - I am implementing the very basic 'Pacifica' document from 2005 using QEMU code as reference.
