ced2c57b67 test/overhead: print error and exit if no device found
While here, do some additional cleanup:

1) add -h option to print help and exit
2) parse args before initializing the environment - this
   allows "overhead -h" to immediately show a usage message
   without having to wait for DPDK to initialize.

8422f88644 test/nvme: increase delay between plugging devices
When the hotplug test was run in a qemu virtual machine, it consistently
failed to unplug the devices after insertion. Increasing the delay here
to four seconds resulted in proper deletion of the devices and a passing
test. (replicated three times)

ce4fcbce71 nvme: add I/O qpair creation options
Add a new struct spdk_nvme_io_qpair_opts to allow the user to override
controller options on a per-I/O qpair basis.

Existing callers with qprio == 0 can be updated to:

  ... = spdk_nvme_ctrlr_alloc_io_qpair(ctrlr, NULL, 0);

Callers that need to specify a non-default qprio should be updated to:

  struct spdk_nvme_io_qpair_opts opts;
  spdk_nvme_ctrlr_get_default_io_qpair_opts(ctrlr, &opts, sizeof(opts));
  opts.qprio = SPDK_NVME_QPRIO_...;

58b9ea3ac0 nvme: Simplify the multiprocess tests
Nearly all tests now make extensive use of the stub application,
so they're effectively all testing multiprocess all the time.
Further, we believe it to be the best policy to not attempt
to support scenarios where the primary process crashes unexpectedly.
We consider this equivalent to a kernel panic and all of the
processes will need to be halted and restarted.

Given the two things above, we can make some fairly dramatic
simplifications to the NVMe multiprocess testing. Only
one piece of functionality - multiple simultaneous secondary
processes - was not already tested by the other regular
tests. This patch removes all other multiprocess tests
and adds a simple test of multiple secondaries.

6052d9a432 nvme.sh: add delay after app startup when they are primary
A short delay is required between starting up a primary and
secondary process with DPDK depending on what the secondary
depends on wrt the primary. As the SPDK sample apps are not
designed to be dependent on each other, when we use them
as primary/secondary in test scripts with no deterministic
synchronization, it is possible for one ore more to hang
resulting in DPDK fatal init failures. Often times this would
show up as a failure to get hugepages in vtophys

A related fix, same failing signature in the same test script,
is also included here where the stub app, which is designed
to act as primary in certain sections of the test script, was
being killed by the test script but the next primary app was
coming up before the process was dead and coming up as a
secondary. A wait was added to assure that the stub process is
gone before the next app tries to start.

50ff9de715 test/nvme/aer: clean up and simplify AER test
The NVMe AER test tries to submit a large number of Get Features
commands during the test cycle to ensure that admin queue wraparound
works and other commands can be issued while still handling AERs
correctly.  However, it tried to do this by submitting all of the Get
Features commands up front, which runs out of admin queue nvme_request
objects.

Change the test to submit one Get Features command per device and
resubmit it as it completes until the test is over.  This exercises
the queue wraparound case without submitting a large number of requests
at once, and it also simplifies the test code.

(3) Hotplug. If asan is enabled, it catches the SEGV earlier

7b7799bf9c fio_plugin: switch to LD_PRELOAD instead of dynamically loading
fio has a race between reap_threads() and free_ioengine().  free_ioengine()
will call the ioengine's cleanup routine and then dlclose it if it
is dynamically linked (like the spdk fio plugin).  free_ioengine() does
not set td->io_ops = NULL though until after dlclose() is complete.  If
reap_threads() tries to dereference td->io_ops after our plugin has been
closed but before io_ops was set to NULL, it will segfault.

Solution (until an upstream fio fix is available) is to use LD_PRELOAD
instead.

27c6d380b5 examples/nvme/perf: add a latency summary
A single -L can be used to get the latency summary.
Two -L's (or -LL) can be used to get both the latency
summary and the detailed histogram.

7b5a229c5f test/hotplug: increase the test time for hotplug
This will make sure the hotplug instance not exit before all the hot insert and
remove events done, the setup.sh for hot insert events will use several seconds
sometimes.

8de75f8107 nvme/perf: add software-based latency tracking
The latency tracking is done with ranges of bucket arrays.
The bucket for any given I/O is determined solely by TSC
deltas - any translation to microseconds is only done after
the test is finished and statistics are printed.

Each range has a number of buckets determined by a
NUM_BUCKETS_PER_RANGE value which is currently set to 128.
The buckets in ranges 0 and 1 each map to one specific TSC
delta.  The buckets in subsequent ranges each map to twice
as many TSC deltas as buckets in the previous range:

Range 0:  1 TSC each - 128 buckets cover deltas    0 to  127
Range 1:  1 TSC each - 128 buckets cover deltas  128 to  255
Range 2:  2 TSC each - 128 buckets cover deltas  256 to  511
Range 3:  4 TSC each - 128 buckets cover deltas  512 to 1023
Range 4:  8 TSC each - 128 buckets cover deltas 1024 to 2047
Range 5: 16 TSC each - 128 buckets cover deltas 2048 to 4095
etc.

While here, change some variable names and usage
messages to differentiate between the existing latency
tracking via vendor-specific NVMe log pages on Intel
NVMe SSDs, and the newly added latency tracking done
in software.

b5b9410da3 nvme: remove DELAY_BEFORE_ENABLE quirk and always wait 100us
A 100us is so small that applying the quirk to the specific
SSDs that require the delay is more trouble than it is worth.
So remove the quirk and always wait 100us before re-enabling
the NVMe SSD during initialization.
