This commmit introduces a new bdev type backed up by DAOS DFS.
Design wise this bdev is a file named as the bdev itself in the DAOS POSIX
container that uses daos event queue per io channel.
Having an event queue per io channel is showing the best IO throughput.
The implementation uses the independent pool and container connections per
device's channel for the best IO throughput.
The semantic of usage is the same as any other bdev type.
To build SPDK with daos support, daos-devel package has to be installed.
The current supported DAOS version is v2.X, please see the installatoin and
setup guide here: https://docs.daos.io/v2.0/
$ ./configure --with-daos
To run it, the target machine should have daos_agent up and running, as
well as the pool and POSIX container ready to use, please see the
detailed requirements here: https://docs.daos.io/v2.0/admin/hardware/.
To export bdev over tcp:
$ ./nvmf_tgt &
$ ./scripts/rpc.py nvmf_create_transport -t TCP -u 2097152 -i 2097152
$ ./scripts/rpc.py bdev_daos_create daosdev0 <pool-label> <cont-label>
1048576 4096
$ ./scripts/rpc.py nvmf_create_subsystem nqn.2016-06.io.spdk1:cnode1 -a -s

$ ./scripts/rpc.py nvmf_subsystem_add_ns nqn.2016-06.io.spdk1:cnode1
daosdev0
$ ./scripts/rpc.py nvmf_subsystem_add_listener nqn.2016-06.io.spdk1:cnode1
-t tcp -a <IP> -s 4420
On the initiator side, make sure that `nvme-tcp` module is loaded then
connect drives, for instance:
$ nvme connect-all -t tcp -a 172.31.91.61 -s 4420
$ nvme list

Note, this change only sets defaults for the ID/KEY,
more specific use cases like NVMe/TCP may set the ID and KEY on a per connection basis.
Also simplify PSK identity string, that isn't NVMe focused.
NVMe libraries using this will need to construct more complicated
identity strings and pass them to the sock layer.
Example:
rpc.py sock_impl_set_options -i ssl --psk-key 4321DEADBEEF1234
rpc.py sock_impl_set_options -i ssl --psk-identity psk.spdk.io

IDXD has always been used everywhere but technically it stands for
the driver, not the HW (Intel Data Streaming Accelerator Driver)
where the X comes from "Streaming Accelerator" somehow. Anyway, the
underlying hardware is just DSA. It doesn't matter much now but
upcoming patches will add support for a new HW accelerator called
the Intel In-Memory Analytics Accelerator which we'll call IAA and
it will use the same (mostly) device driver (IDXD) as DSA. So, calling
the HW what it is will lessen confusion when adding IAA support.
This patch just does renaming for the accel_fw module and associated
files (RPC, etc).

It's now possible to specify a time to wait until a connection to the
discovery controller and the NVM controllers it exposes is made.
Whenever that time is exceeded, a callback is immediately executed.
However, depending on the stage of the discovery process, we might need
to wait a while before actually stopping it (e.g. because a controller
attach is in progress). That means that a discovery service might be
visible for a while after it timed out.

By default, failback to the preferred I/O path is done automatically
if it is restored. Some users may want to keep using the backup I/O
path even if the preferred I/O path is restored. In this case,
bdev_nvme_set_preferred_path can be used to do manual failback.
We may be able to clear/fill I/O path cache more strictly but it will
be complicated and have bugs. This patch does the minimal change,
just skips an apparent case.

The RPC returns a list of active discovery service connections. Each
discovery service is described by a name, its trid, and a list of

The NVMe bdev module supported active-passive policy for multipath mode
first. By this patch, the NVMe bdev module supports active-active policy
for multipath node next. Following the Linux kernel native NVMe multipath,
the NVMe bdev module supports round robin algorithm for active-active
policy.
The multipath policy, active-passive or active-active, is managed per
nvme_bdev. The multipath policy is copied to all corresponding
nvme_bdev_channels.
Different from active-passive, active-active caches even non_optimized
path to provide load balance across multiple paths.
