I missed that thread. So basically external memory with IOVA as VA mode
is not supported in POWER9 systems as it's memseg lists can be created later
after DMA window size is fixed. Correct ?

Since I'm mmapin'g normal pages for this test outside EAL, I cannot use memseg list 
range as VA as it is already reserved by memseg list's.

I can see only three options left.

#1 Use initial process VA range by using heap memory instead of mmap 
which is falling below eal's base_virtaddr for both freebsd and windows and also I think 
your DMA window will include that.

#2 Use PA from real PA range or like externel_mem_autotest(). The test currently
   is acting like IOVA as VA test but this change will make it as IOVA as PA.

#3 Disable this test for VFIO SPAPR or remove it completely.

Will #1 work in your case ?
