6ae86a059b firt cleanup in SVM code. added intercept check for MSR and IO 2011-12-26 19:57:39 +00:00

8b4a2c2034 implemented some more intercepts. 
fixed compilation without SVM

75bda1d5cd implemented SVM emulation support for Bochs (incomplete yet) 
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.

f15bc6cf75 support for NX outside of x86-64. 
required for Intel Yonah processor which is another interesting CPUID to be added
also found Via C7 CPUID, looking for the way to add it too
