net/ifc: support SW assisted VDPA live migration
In SW assisted live migration mode, driver will stop the device and
setup a mediated virtio ring to relay the communication between the
virtio driver and the VDPA device.
This data path intervention will allow SW to help on guest dirty page
logging for live migration.
This SW fallback is event driven relay thread, so when the network
throughput is low, this SW fallback will take little CPU resource, but
when the throughput goes up, the relay thread's CPU usage will goes up
accordingly.
User needs to take all the factors including CPU usage, guest perf
degradation, etc. into consideration when selecting the live migration

- An introduction, where a brief explanation of this driver is given,
pointing out the dependency on PACKET_MMAP;
- Which options are supported at configuration time, while setting up an

- What the prerequisites are;
- A command line example of how to set up a DPDK port using the

malloc: fix deadlock when reading stats
Currently, malloc statistics and external heap creation code
use memory hotplug lock as a way to synchronize accesses to
heaps (as in, locking the hotplug lock to prevent list of heaps
from changing under our feet). At the same time, malloc
statistics code will also lock the heap because it needs to
access heap data and does not want any other thread to allocate
anything from that heap.
In such scheme, it is possible to enter a deadlock with the
following sequence of events:
thread 1 thread 2
rte_malloc()
rte_malloc_dump_stats()
take heap lock
take hotplug lock
failed to allocate,
attempt to take
hotplug lock
attempt to take heap lock
Neither thread will be able to continue, as both of them are
waiting for the other one to drop the lock. Adding an
additional lock will require an ABI change, so instead of
that, make malloc statistics calls thread-unsafe with
respect to creating/destroying heaps.

The general use-case of using external memory is well covered by

added to DPDK's internal structures, so that API's like

malloc: notify primary process about hotplug in secondary
When secondary process hotplugs memory, it sends a request
to primary, which then performs the real mmap() and sends
sync requests to all secondary processes. Upon receiving
such sync request, each secondary process will notify the
upper layers of hotplugged memory (and will call all
locally registered event callbacks).
In the end we'll end up with memory event callbacks fired
in all the processes except the primary, which is a bug.
This gets critical if memory is hotplugged while a VFIO
device is attached, as the VFIO memory registration -
which is done from a memory event callback present in the
primary process only - is never called.
After this patch, a primary process fires memory event
callbacks before secondary processes start their
synchronizations - both for hotplug and hotremove.

malloc: add option --match-allocations
SPDK uses the rte_mem_event_callback_register API to
create RDMA memory regions (MRs) for newly allocated regions
of memory. This is used in both the SPDK NVMe-oF target
and the NVMe-oF host driver.
DPDK creates internal malloc_elem structures for these
allocated regions. As users malloc and free memory, DPDK
will sometimes merge malloc_elems that originated from
different allocations that were notified through the
registered mem_event callback routine. This results
in subsequent allocations that can span across multiple
RDMA MRs. This requires SPDK to check each DPDK buffer to
see if it crosses an MR boundary, and if so, would have to
add considerable logic and complexity to describe that
buffer before it can be accessed by the RNIC. It is somewhat
analagous to rte_malloc returning a buffer that is not
IOVA-contiguous.
As a malloc_elem gets split and some of these elements
get freed, it can also result in DPDK sending an
RTE_MEM_EVENT_FREE notification for a subset of the
original RTE_MEM_EVENT_ALLOC notification. This is also
problematic for RDMA memory regions, since unregistering
the memory region is all-or-nothing. It is not possible
to unregister part of a memory region.
To support these types of applications, this patch adds
a new --match-allocations EAL init flag. When this
flag is specified, malloc elements from different
hugepage allocations will never be merged. Memory will
also only be freed back to the system (with the requisite
memory event callback) exactly as it was originally
allocated.
Since part of this patch is extending the size of struct
malloc_elem, we also fix up the malloc autotests so they
do not assume its size exactly fits in one cacheline.

timer: fix race condition
rte_timer_manage() adds expired timers to a "run list", and walks the
list, transitioning each timer from the PENDING to the RUNNING state.
If another lcore resets or stops the timer at precisely this
moment, the timer state would instead be set to CONFIG by that other
lcore, which would cause timer_manage() to skip over it. This is
expected behavior.
However, if a timer expires quickly enough, there exists the
following race condition that causes the timer_manage() routine to
misinterpret a timer in CONFIG state, resulting in lost timers:
- Thread A:
- starts a timer with rte_timer_reset()
- the timer is moved to CONFIG state
- the spinlock associated with the appropriate skiplist is acquired
- timer is inserted into the skiplist
- the spinlock is released
- Thread B:
- executes rte_timer_manage()
- find above timer as expired, add it to run list
- walk run list, see above timer still in CONFIG state, unlink it from
run list and continue on
- Thread A:
- move timer to PENDING state
- return from rte_timer_reset()
- timer is now in PENDING state, but not actually linked into a
pending list or a run list and will never get processed further
by rte_timer_manage()
This commit fixes this race condition by only releasing the spinlock
after the timer state has been transitioned from CONFIG to PENDING,
which prevents rte_timer_manage() from seeing an incorrect state.

bbdev: enhance throughput test
Improvements added to throughput test:
- test is run in loop (number of iterations is specified by
TEST_REPETITIONS define) which ensures more accurate results
- length of input data is calculated based on amount of CBs in TB
- maximum number of decoding iterations is gathered from results
- added new functions responsible for printing results
- small fixes for memory management
