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.
XOP: few instructions are still missing, coming soon
BX_PANIC(("VPERMILPS_VpsHpsWpsVIbR: not implemented yet"));
BX_PANIC(("VPERMILPD_VpdHpdWpdVIbR: not implemented yet"));
BX_PANIC(("VPMADCSSWD_VdqHdqWdqVIbR: not implemented yet"));
BX_PANIC(("VPMADCSWD_VdqHdqWdqVIbR: not implemented yet"));
BX_PANIC(("VFRCZPS_VpsWpsR: not implemented yet"));
BX_PANIC(("VFRCZPD_VpdWpdR: not implemented yet"));
BX_PANIC(("VFRCZSS_VssWssR: not implemented yet"));
BX_PANIC(("VFRCZSD_VsdWsdR: not implemented yet"));
So now the same single option will choose not only the CPUID flags but also VMX capabilities matching real HW machine.
Removed cpuid of core2_extreme_x9770 from the cpudb. I don't remember its VMX capabilities anyway.
There is another Penryn model in the cpudb - core2_penryn_t9600.
32-bit CPU using Bochs binary compiled with x86-64 support.
The commit also fixes some init.cc issues with initialization of SYSCALL/SYSRET MSR in AMD hosts and also includes code reorg.
with --enable-avx option. When compiled in, AVX still has to be enabled
using .bochsrc CPUID option. AVX2 FMA instructions still not implemented.
- Added support for Bit Manipulation Instructions (BMI) emulation. The BMI
instructions support can be enabled using .bochsrc CPUID option.
Change CPUID to generic interface which could be chosen from .bochsrc.
Bochs CPU emulation will enable/disable features (like instruction sets) according to CPUID that is selected.
TODO: Add database of CPUID from real hardware CPUs
