Dear Yaniv, Dear Avi,
I would like to add the "sidt emulation" feature in kvm, but in order to
implement it I need to know the details on how the OPCODE works and how
exactly opcodes are emulated within kvm.
For example let's take the SIDT instruction.
I know the LIDT opcode is "0F 01 /1" but what does 0F, 01 and /1 mean?
I also know that this instruction has only the operand "ModRM:r/m (w)"
but where is this operand stored and how can I access it in emulation?
Could you please suggest to me where can I found some detailed docs on
the subject?
(I have already read the Intel Volume 2B Instruction Set Reference N-Z
pag. 4-440 but I have not found enough detailed information)
Thank you
Matteo Signorini
