edbb7ace72 bdev/nvme: Include path removal into bdev_nvme_failover()
Add the second parameter remove and include path removal into
bdev_nvme_failover(). Additionally, bdev_nvme_failover() returns
only two return values, 0 or -EAGAIN, and hence change
bdev_nvme_remove_trid() to return the return value of
bdev_nvme_failover() directly.

01f769c62a bdev/nvme: Ensure ctrlr->destruct is set only once
Checking if destruct is false and setting destruct to true are
separated by mutex in remove_cb() and bdev_nvme_library_fini().

It was possible that multiple threads called nvme_bdev_ctrlr_destruct()
because the caller could call nvme_bdev_ctrlr_destruct() before
setting destruct to true after knowing it was false.

This patch ensures that nvme_bdev_ctrlr_destruct() is called only once.

Set ctrlr->destruct to true without releasing mutex after checking
if ctrlr->destruct is false.

If destruct is set to true before calling nvme_ctrlr_depopulate_namespaces(),
nvme_ctrlr_depopulate_namespace_done() may call nvme_bdev_ctrlr_destruct()
because it is likely that reference count is zero and destruct is true.
In this case, remove_cb() or bdev_nvme_library_fini() cannot call
nvme_bdev_destruct() after returning from nvme_ctrlr_depopulate_namespaces().

On the other hand, if a controller has no namespace,
nvme_ctrlr_depopulate_namespaces() does nothing and
nvme_ctrlr_depopulate_namespace_done() is not called. Hence
remove_cb() or bdev_nvme_library_fini() has to call nvme_bdev_destruct()
after returning nvme_ctrlr_depopulate_namespaces().

To unify both cases, initialize reference count to one as a sentinel value
and remove_cb() and bdev_nvme_library_fini() decrement reference count
and then calls nvme_bdev_ctrlr_destruct() if reference count is zero
after returning from nvme_ctrlr_depopulate_namespaces().

Additionally, add assert to check if reference count is not negative
to find bug in future.

93a91be642 bdev/nvme: Factor out common operation of create_cb() and reset_create_qpair()
To improve readability and make the following patches easier,
factor out the common operation of bdev_nvme_create_cb() and
_bdev_nvme_reset_create_qpair() into bdev_nvme_create_qpair(),
and factor out the main operation of bdev_nvme_destroy_cb()
into bdev_nvme_destroy_qpair(). bdev_nvme_destroy_qpair() is used
in the error path of bdev_nvme_create_qpair().

Updating g_opts.io_queue_requests again is no harm and so is done
in bdev_nvme_create_qpair().

Use the term nvme_ch in bdev_nvme_create_cb() and bdev_nvme_destroy_cb()
for clarification.

Two admin APIs, bdev_nvme_abort() and bdev_nvme_admin_passthru()

acfb968aa8 bdev/nvme: avoid spdk_bdev_io_get_buf call when possible
The bdev layer nicely handles the case where we call this
function with the buffers already present - it just
immediately calls the get_buf_cb.  But this adds extra
overhead in the case where the buffer is already present.
Since nvme has no alignment restrictions, we can just
check the iovs directly and avoid the extra call to
spdk_bdev_io_get_buf when possible.

Call spdk_nvme_ns_cmd_write_with_md if there is only one iov element.
Use spdk_nvme_ns_cmd_writev_with_md only if there is more than one.

It's cheaper to call spdk_nvme_ns_cmd_read_with_md than it is to call

47b0d4275c bdev/nvme: Support abort IO by using spdk_nvme_ctrlr_cmd_abort_ext()
Change NVMe bdev module to enable abort as IO type.

Change _bdev_nvme_submit_request() to process abort request when the
IO type is abort.

The current thread tries aborting I/O command in the I/O qpair first.
If no I/O command to abort was found, send message to the thread which
is registered when creating controller. The controller thread tries
aborting admin command in the admin qpair next. If no admin command
to abort was found, complete the abort request with failure.

spdk_nvme_ctrlr_cmd_abort_ext() is used to try aborting command whose
cb_arg matches. qpair is set to NULL when trying to abort admin command.

Before calling spdk_nvme_ctrlr_cmd_abort_ext(), save the current
thread to process admin command completion correctly.

spdk_bdev_abort() supports any bdev module other than NVMe bdev
module and does not check CDW0 but checks only if the completion
status is success or failure. So add bdev_nvme_abort_done() and
converts the NVMe completion status to the bdev completion status.

c241161ad2 bdev/nvme: set default admin poll period to 10ms
Sending large amounts  of data from host to the controller with 1s
admin polling time, take a lot of time (e.g. 1M firmware file in 4k
chunks takes ~17min).

Reducing this time to 10ms whole operation takes about 3s.

ba7b55de87 bdev/nvme: do not destruct ctrlr if reset is in progress
The adminq poller could get a failure if the ctrlr has
already been hot removed, which starts a reset.

But while the for_each_channel is running for the reset,
the hotplug poller could run and start the destruct
process.  If the ctrlr is deleted before the for_each_channel
completes, we will try to call spdk_nvme_ctrlr_reset() on
a deleted controller.

While here, also add a check to skip the reset if the
controller is already in the process of being removed.

Fixes #1273.

This isn't in the performance path, so using the mutex

This patch adds the ability for a namespace to be depopulated

OCSSD ones are depopulated synchronously, but it'll be changed in the

The nvme_bdev_ctrlr.ref is now not only tracking the number of bdevs
created on that controller, but also the number of populated namespaces.

after a change was made to get transports by name to allow for custom
transport types. This change fills in the trstring so that downstream
checks correctly pass.

6db4a00c58 bdev/nvme: depopulate namespaces in module_fini callback
Currently the namespaces are depopulated in two cases: if the controller
is detached (either due to its hot unplug or RPC call) or due to
"namespace attribute changed" asynchronous event.  It means that during
shutdown, when nvme_bdev_ctrlr is destroyed, the namespaces aren't
depopulated.

For regular NVMe namespaces it isn't a big issue, since their only
depopulate task is to unregister bdevs created on that namespace, which
is already done by the bdev layer.  However, it can be a problem for
other types of namespaces (e.g. Open Channel), as they might allocate
their own context in nvme_bdev_ns.type_ctx, which, unless the namespace
is depopulated, cannot be freed.

This is a temporary solution that should be removed once bdev_ftl

controllers.

'delay_pcie_doorbel' parameter in 'spdk_nvme_io_qpair_opts' structure
was renamed to 'delay_cmd_submit' to make it suitable for every
transport. Old name is also kept for backward compatibility.

b9635c2f16 bdev/nvme: move nvme_io_channel to common.h
Other NVMe bdev modules (e.g. OCSSD) need the definition of the
nvme_io_channel to be able to send IO requests, so this structure has to
be defined in the common header.

a116324c88 bdev/ocssd: initial Open Channel bdev implementation
This patch adds initial Open Channel zoned bdev implementation.  The
bdev will allow to use the zoned API on top of OCSSD devices.

Added the ability to create the OCSSD NVMe controller.  The controller
is created using the regular NVMe's RPC when the controller is detected
to be Open Channel.
