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.

b67dde5b19 drivers/dpaa: reduce meson dependency lists
Meson build currently tracks the dependencies between libraries, which
can often make things easier, but has the side-effect of slowing down
the initial meson run if too many duplicated dependencies are provided.
Therefore, we remove dependencies from the dpaa items where other
dependencies already depend on those. This provides a noticable speed-up
in meson configuration runs when lots of sample apps are included in the
build.

a6cdf375bc bus/fslmc: move VFIO DMA map into bus probe
fslmc bus needs to map all allocated memory for VFIO before
device probe. This bus doesn't support hotplug, so at the time
of this call, all possible device that could be present, are
present. This will also be the place where we install VFIO
callback, although this change will come in the next patch.

Since rte_fslmc_vfio_dmamap() is now only called at bus probe,
there is no longer any need to check if DMA mappings have been
already done.

66cc45e293 mem: replace memseg with memseg lists
Before, we were aggregating multiple pages into one memseg, so the
number of memsegs was small. Now, each page gets its own memseg,
so the list of memsegs is huge. To accommodate the new memseg list
size and to keep the under-the-hood workings sane, the memseg list
is now not just a single list, but multiple lists. To be precise,
each hugepage size available on the system gets one or more memseg
lists, per socket.

In order to support dynamic memory allocation, we reserve all
memory in advance (unless we're in 32-bit legacy mode, in which
case we do not preallocate memory). As in, we do an anonymous
mmap() of the entire maximum size of memory per hugepage size, per
socket (which is limited to either RTE_MAX_MEMSEG_PER_TYPE pages or
RTE_MAX_MEM_MB_PER_TYPE megabytes worth of memory, whichever is the
smaller one), split over multiple lists (which are limited to
either RTE_MAX_MEMSEG_PER_LIST memsegs or RTE_MAX_MEM_MB_PER_LIST
megabytes per list, whichever is the smaller one). There is also
a global limit of CONFIG_RTE_MAX_MEM_MB megabytes, which is mainly
used for 32-bit targets to limit amounts of preallocated memory,
but can be used to place an upper limit on total amount of VA
memory that can be allocated by DPDK application.

So, for each hugepage size, we get (by default) up to 128G worth
of memory, per socket, split into chunks of up to 32G in size.
The address space is claimed at the start, in eal_common_memory.c.
The actual page allocation code is in eal_memalloc.c (Linux-only),
and largely consists of copied EAL memory init code.

Pages in the list are also indexed by address. That is, in order
to figure out where the page belongs, one can simply look at base
address for a memseg list. Similarly, figuring out IOVA address
of a memzone is a matter of finding the right memseg list, getting
offset and dividing by page size to get the appropriate memseg.

This commit also removes rte_eal_dump_physmem_layout() call,
according to deprecation notice [1], and removes that deprecation
notice as well.

On 32-bit targets due to limited VA space, DPDK will no longer
spread memory to different sockets like before. Instead, it will
(by default) allocate all of the memory on socket where master
lcore is. To override this behavior, --socket-mem must be used.

The rest of the changes are really ripple effects from the memseg
change - heap changes, compile fixes, and rewrites to support
fbarray-backed memseg lists. Due to earlier switch to _walk()
functions, most of the changes are simple fixes, however some
of the _walk() calls were switched to memseg list walk, where
it made sense to do so.

Additionally, we are also switching locks from flock() to fcntl().
Down the line, we will be introducing single-file segments option,
and we cannot use flock() locks to lock parts of the file. Therefore,
we will use fcntl() locks for legacy mem as well, in case someone is
unfortunate enough to accidentally start legacy mem primary process
alongside an already working non-legacy mem-based primary process.

496324d2a5 bus/fslmc: add flag to configure DCA in QBMAN multi Tx
With the current QBMAN multi-tx API, we need to create separate
enqueue descriptors for each of the packet which is required to
be enqueued to the hardware, once we support Atomic Queues
(with DCA) in dpaa2 drivers. Creating enqueue descriptor for
each packet is costly and have significant performance impact.
This patch introduces a flag parameter in the QBMAN multi-tx API,
so that DCA configuration (and later on ORP/ODP for ordered queues)
can be passed using flags and be updated in the EQCR using this flag.

7b6edb640b event/dpaa2: have separate structure to hold dqrr entries
This patch provides cleaner approach to store the DQRR entries,
which are yet to be consumed in case of atomic queues.

Also, this patch changes the storage of the DQRR entry index
into the mbuf->seqn instead of ev->opaque
