350e429a57 rdma: add a flag for disabling srq.
There are cases where srq can be a detriment. Add a flag to allow users
to disable srq even if they have a piece of hardware that supports it.

f50d3d7759 reactor: pin spdk threads to their cores
We're about to drop legacy event messages from SPDK libs
and for that we'll replace various lcore numbers with
spdk_thread objects. For now SPDK libs can't spawn their
own threads, so they must use spdk_for_each_thread() and
spdk_get_thread() to retrieve different thread pointers.

The vhost library offers API to construct a vhost device
to be polled on specified cores, and in order to keep that
functionality we'll need to know which core each thread
is polling on. We would like to achieve that with
spdk_thread_get_cpumask(), but right now it always returns
all cores, so this patch changes it to return just
a single cpu on which the thread is actually pinned. It's
only a stop gap, eventually the vhost library will spawn
its own threads with custom cpumasks.

38527b0786 lib/thread: Fix wrong posix thread name by SPDK thread scheduler
Before enabling SPDK thread scheduler,
each POSIX thread name was reactor_% (% was the core number).

After enabling SPDK thread scheduler, the name of the master POSIX
thread is reactor_% (% is the max core number), and the name of the
slave posix threads are lcore-slave-% (% is the current core number).

SPDK threads are light-weight threads - sometimes also called
green threads or fibers, and so are independent from posix
threads.

But reactor is tied to the POSIX thread in the SPDK event library.

So SPDK thread doesn't rename the POSIX thread at its creation
but reactor renames the POSIX thread at start instead.

This change makes POSIX thread name compatible between before and
after enabling SPDK thread scheduler.

1c297d7e30 thread: fix crash on non-contiguous cpu range in cpumask
Limit the thread scheduler to put spdk_threads on
lcores < last_lcore instead of lcores < lcore_count,
which was probably the original intent.

When the cpumask was not a contiguous cpu range, the
thread scheduler failed to schedule any spdk_threads on
the last cores. There was one hardcoded thread created
for each reactor, but the scheduler could squash some
of those into a single reactor. This broke the legacy
lcore-based messages as those expect there to be at least
one spdk_thread per lcore. Any spdk_poller_register()
or spdk_get_io_channel() called from such a legacy
message would fail an assertion, as spdk_get_thread()
returned NULL.

Fixes #743

section in the cfg file. Let's remove that requirement.

ed0b611fc5 nvmf/rdma: Add shared receive queue support
This is a new feature for NVMEoF RDMA target, that is intended to save
resource allocation (by sharing them) and utilize the
locality (completions and memory) to get the best performance with
Shared Receive Queues (SRQs). We'll create a SRQ per core (poll
group), per device and associate each created QP/CQ with an
appropriate SRQ.

Our testing environment has 2 hosts.
Host 1:
  CPU: Intel(R) Xeon(R) CPU E5-2609 0 @ 2.40GHz dual socket (8 cores total)
  Network: ConnectX-5, ConnectX-5 VPI , 100GbE, single-port QSFP28, PCIe3.0 x16
  Disk: Intel Optane SSD 900P Series
  OS: Fedora 27 x86_64
Host 2:
  CPU: Intel(R) Xeon(R) CPU E5-2630 v2 @ 2.60GHz dual-socket (24 cores total)
  Network: ConnectX-4 VPI , 100GbE, dual-port QSFP28
  Disk: Intel Optane SSD 900P Series
  OS : CentOS 7.5.1804 x86_64
Hosts are connected via Spectrum switch.
Host 1 is running SPDK NVMeoF target.
Host 2 is used as initiator running fio with SPDK plugin.

Configuration:
- SPDK NVMeoF target: cpu mask 0x0F (4 cores), max queue depth 128,
  max SRQ depth 1024, max QPs per controller 1024
- Single NVMf subsystem with single namespace backed by physical SSD disk
- fio with SPDK plugin: randread pattern, 1-256 jobs, block size 4k,
  IO depth 16, cpu_mask 0xFFF0, IO rate 10k, rate process “poisson”

Here is a full fio command line:
fio  --name=Job --stats=1 --group_reporting=1 --idle-prof=percpu \
--loops=1 --numjobs=1 --thread=1 --time_based=1 --runtime=30s \
--ramp_time=5s --bs=4k --size=4G --iodepth=16 --readwrite=randread \
--rwmixread=75 --randrepeat=1 --ioengine=spdk --direct=1 \
--gtod_reduce=0 --cpumask=0xFFF0 --rate_iops=10k \
--rate_process=poisson \
--filename='trtype=RDMA adrfam=IPv4 traddr=1.1.79.1 trsvcid=4420 ns=1'

SPDK allocates the following entities for every work request in
receive queue (shared or not): reqs (1024 bytes), recvs (96 bytes),
cmds (64 bytes), cpls (16 bytes), in_capsule_buffer. All except the
last one are fixed size. In capsule data size is configured to 4096.
Memory consumption calculation (target):
- Multiple SRQ: core_num * ib_devs_num * SRQ_depth * (1200 +
  in_capsule_data_size)
- Multiple RQ: queue_num * RQ_depth * (1200 + in_capsule_data_size)
We ignore admin queues in calculations for simplicity.

Cases:
1. Multiple SRQ with 1024 entries:
   - Mem = 4 * 1 * 1024 * (1200 + 4096) = 20.7 MiB
     (Constant number – does not depend on initiators number)
2. RQ with 128 entries for 64 initiators:
   - Mem = 64 * 128 * (1200 + 4096) = 41.4 MiB

4e331534f1 event/subsystem: solve the subsystem init and destroy conflict
We have conflict to handle the NVMf subsystem shut
down. The situation is that:

If there is shutdown request (e.g., ctrlr+c),
we may have subsystem finalization and subsystem
initialization conflict (e.g., have NVMf subsystem fini and
intialization together), we will have coredump
issue like #682.

If we interrupt the initialization of the subsystem,
following works should do:

1  Do not initilize the next subsystem.
2  Recycle the resources in each subsystem via the
spdk_subsystem_fini related function. And this patch will
do the general thing, but will not consider the detailed
interrupt policy in each subsystem.

a206234d09 lib/trace: add trace_record tool
trace_record is used to poll the spdk trace shm file
and store new entries from it to another specified trace file.
This could help retain the trace_entires from the overlay of
trace circular buffer

Note:
* trace_record reads the input tracefile into a process-local
memory and writes trace entries to the output file only at shutdown.
* trace_record can be shut down on SIGINT or SIGTERM signal.

A usage sample is:
./spdk_trace_record -s bdev_svc -p <spdk app pid> -f trace.tmp -q
