You can find the domain and the real memory address within the domain that correspond to a given physical memory address (PA).
First, generate a long parseable list for all domains.
primary# ldm list -l -p
Look for the line in the list's MEMORY sections where the PA falls within the inclusive range pa to (pa + size - 1); that is, pa ≤ PA ≤ (pa + size - 1). pa and size refer to the values in the corresponding fields of the line.
If you find such an entry, the PA is in the domain the entry is listed under and the corresponding real address within the domain is given by ra + (PA - pa).
If you do not find such an entry, the PA is not in any domain.
