> With V2, Tests with 512MB & 2M page sizes work fine with octeontx2 mempool pmd. One more concern is, octeontx fpa mempool driver also has the similar requirements. How do we address that, Can you suggest the best way to avoid code duplication in PMDs.

# Actually both drivers don't call any HW specific function on those ops
# Is it possible to move the code under "  /* derived from
rte_mempool_op_calc_mem_size_default() */"
to static function in the mempool lib
ie.
it will keep the generic rte_mempool_op_calc_mem_size_default() clean
and we can introduce
other variant of rte_mempool_op_calc_mem_size_default() for this
specific requirement  which inclues the static generic function.

I don't think, it is a one-off requirement to have an object size
aligned to object start address in all HW based mempool
implementation.

The reason for the HW scheme doing such a scheme is the following:
# if object size aligned to object block size, when HW wants to
enqueue() a packet back to pool,
irrespective of the free pointer offset it can enqueue the mbuf
address to mempool.

Example:
X - mbuf start address
Y - the object block size
X + n <- is the packet pointer to send the packet

When submitting the packet o HW to send the packet, SW needs to only
mention the X + n and
when HW frees it, it can derive the X(mbuf pointer address) by the
following arithmetic
X = (X + n ) - ((X + n) MOD Y)

Hi Olivier,
It is not worth going back and forth on this code organization. You
can decide on a scheme, We will follow that.
