157e55f82d mempool/octeontx2: remove minimum chunck size limitation
Memory required for the mempool objects need not be physically
contiguous on octeontx2's HW, mempool pmd supports the minimum chunk
size set by the default handler. Hence discarding the limitation set
by the pmd on the min_chunk_size value.

195981133a common/octeontx2: fix mbox memory access
Octeontx2 PMD's mailbox client uses device memory to send messages
to mailbox server in the admin function Linux kernel driver.
The device memory used for the mailbox communication needs to
be qualified as volatile memory type to avoid unaligned device
memory accesses because of compiler's memory access coalescing.

This patch modifies the mailbox request and responses as volatile
type which were non-volatile earlier and accessed from unaligned
memory addresses which resulted in bus errors on Fedora 30 with
gcc 9.1.1.

a78ffb5dd4 mempool/octeontx2: fix pool populating
Fix npa pool range errors observed while creating mempool, this issue
happens when mempool objects are from different mem segments.

During mempool creation, octeontx2 mempool driver populates pool range
fields before enqueuing the buffers. If any enqueue or dequeue operation
reaches npa hardware prior to the range field's HW context update,
those ops result in npa range errors. Patch adds a routine to read back
HW context and verify if range fields are updated or not.

  	int64_t * const addr = (int64_t * const)

This is because of the nature of const.
In this example, the expression is being cast into a pointer
that can not be modified. This is meaningless because the
expression is already a lvalue.

9a8e7062c8 mempool/octeontx2: add devargs for max pool selection
The maximum number of mempools per application needs to be configured
on HW during mempool driver initialization. HW can support up to 1M
mempools, Since each mempool costs set of HW resources, the max_pools
devargs parameter is being introduced to configure the number of
mempools required for the application.
For example:

-w 0002:02:00.0,max_pools=512

With the above configuration, the driver will set up only 512 mempools
for the given application to save HW resources.

e75bc77f98 mempool/stack: add lock-free stack mempool handler
This commit adds support for lock-free (linked list based) stack mempool
handler.

In mempool_perf_autotest the lock-based stack outperforms the
lock-free handler for certain lcore/alloc count/free count
combinations*, however:
- For applications with preemptible pthreads, a standard (lock-based)
  stack's worst-case performance (i.e. one thread being preempted while
  holding the spinlock) is much worse than the lock-free stack's.
- Using per-thread mempool caches will largely mitigate the performance
  difference.

*Test setup: x86_64 build with default config, dual-socket Xeon E5-2699 v4,
running on isolcpus cores with a tickless scheduler. The lock-based stack's
rate_persec was 0.6x-3.5x the lock-free stack's.

06d5038a47 bus/dpaa: optimize physical to virtual address search
With Hotplugging memory support, the order of memseg has been changed
from physically contiguous to virtual contiguous. DPAA bus and drivers
depend on PA to VA address conversion for I/O.

This patch creates a list of blocks requested to be pinned to the
DPAA mempool. For searching physical addresses, it is expected that
it would belong to this list (from hardware pool) and hence it is
less expensive than memseg walks. Though, there is a marginal drop
in performance vis-a-vis the legacy mode with physically contiguous
memsegs.

365fb925d3 bus/fslmc: optimize physical to virtual address search
With Hotplugging memory support, the order of memseg has been changed
from physically contiguous to virtual contiguous. FSLMC bus and dpaa2
drivers depend on PA to VA address conversion when in Physical
addressing mode.

This patch creates a list of blocks requested to be pinned to the
DPAA2 mempool. For searching physical addresses, it is expected that
it would belong to this list (from hardware pool) and hence it is
less expensive than memseg walks. Though, this has marginal impact on
performance vis-a-vis legacy mode with physically contiguous memsegs.
