I have two questions, both regarding the virtual-physical translation of addresses (all in the virtual machine context).
1> Can somebody tell me if the program counter value available in the following snippet from target-i386/translate.c
is virtual or physical? I learnt it may be virtual, in which case is there a way to extract the physical address corresponding to the virtual address, or if it is physical, then is there a way to translate to its virtual address (within the virtual machine context)?
************************************************ /* convert one instruction. s->is_jmp is set if the translation must be stopped. Return the next pc value */ static target_ulong disas_insn(DisasContext *s, target_ulong pc_start)
{ int b, prefixes, aflag, dflag; int shift, ot; int modrm, reg, rm, mod, reg_addr, op, opreg, offset_addr, val; target_ulong next_eip, tval; int rex_w, rex_r;
s->pc = pc_start; // This s->pc is what I am using to extract all executed PC values
************************************************
2> Second question I have is - Within the functions from target-i386/ops_mem.h for example,
