It is not exactly what i need.
I have some virtual memory address inside qemu.
I need to get value, which is stored in this address.

I'm trying to do as follow
1. Get phys address of given virtual address into tmp_addr
     get_phys_addr (env, address, access_type, is_user, &tmp_addr, 
&tmp_prot);

2. read value of which is stored in physical address (tmp_addr)
   cpu_physical_memory_read (tmp_addr, &result, 1);

Is it correct way?
