Of course no true random numbers will be generated - use standard "C" rand() function as stub.
In future it will be possible to improve (using another random generator) or even use real rdrand/rdseed intrinsics
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.
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.
- Fixed critical bug in CPU code added with one of the prev commits
- Disasm support for SSE4
- Rename PNI->SSE3 everywhere in the code
- Correctly decode, disassemble and execute 'XCHG R8, rAX' x86-64 instruction
- Correctly decode, disassemble and execute multi-byte NOP 0F F1 opcode
- Fixed ENTER and LEAVE instructions in x86-64 mode
- Added ability to turn ON instruction trace, only GUI support is missed.
Instruction trace could be enabled if Bochs was compiled with disasm
- More changes Bit32u -> bx_phy_address
- Complete preliminary implementation of SMM in Bochs, SMI is still PANICs but if you press 'continue' everything should work OK
- Small code cleanup
- Update CHANGES and user docs
Fixed operand for CMPXCHG8B instruction
Feature request to somebidy who understand Bochs debugger code
- to add Bochs debugger command which will switch between
Intel and AT&T style for disassembler.
Prepared for AT&T style support in Bochs disassembler
- it already supports all AT&T style except opcode name suffixes
- AT&T support in future will be possible to enable from bx_debugger
split REPEAT instructions according to opsize to speedup execution
now each REPEATABLE instruction splitted to 3 different instructions, one for 16-bit operand size, one for 32-bit and one for 64-bit. Choosing of correct instruction occure in fetchdecode step.
