Patch 55f947933 ("bdev: remove spdk_bdev_ext_io_opts from spdk_bdev_io")
changed the way bdev_nvme submits IO to the NVMe driver causing
performance degradation for requests with iovcnt = 1, as they also had
to go through the path that executes the reset_sgl/next_sge callbacks.
This patch reverts those changes back to the original code checking
iovcnt and using the non-SGL functions if possible.

This is the beginning of support for external snapshots. An external
snapshot is a read-only blobstore device (struct spdk_bs_dev) that can
be used as a blob's back device. Normally a blob will have no back
device (a normal blob), a zeroes back device (a thin provisioned blob),
or a blob back device (a clone blob). When a blob has an external
snapshot ("esnap") as its back device, it is called an esnap clone.
With this patch, esnap clones can be created but they are not yet
useful. Subsequent patches in the series will plumb the IO path, enable
various features, and allow lvol bdevs to be esnap clones.

If a driver is registered and selected, it'll now be used to execute
sequences of accel operations. The driver has priority over accel
modules, so the modules will only be used to execute operations that the
driver cannot perform.
Once driver completes a task (or a number of tasks), it notifies accel
using standard spdk_accel_task_complete(). To let accel continue
processing a sequence, driver can call spdk_accel_sequence_continue().
This can be done when the driver executes all tasks (1), an error occurs
(2), or the driver doesn't know how to execute a given opcode (3). In
case of (3), that operation will be executed using appropriate accel
module and, while the rest of the sequence will be sent back to the
driver.

The spdk_bdev_ext_io_opts structure is used to pass extra options when
submitting a bdev IO request, without having to modify/add functions to
handle new options. Additionally, the structure has a size field to
allow adding new fields without breaking the ABI (and thus having to
bump up the major version of a library).
It is also a part of spdk_bdev_io and there are several reasons for
removing it from that structure:
1. The size field only makes sense in structures that are passed
through pointers. And spdk_bdev_ext_io_opts is indeed passed as a
pointer to spdk_bdev_{readv,writev}_blocks_ext(), however it is
also embedded in spdk_bdev_io (internal.ext_opts_copy), which is
also part of the API. It means that each time a new field is added
to spdk_bdev_ext_io_opts, the size of spdk_bdev_io will also
change, so we will need to bump the major version of libspdk_bdev
anyway, thus making spdk_bdev_ext_io_opts.size useless.
2. The size field also makes internal.ext_opts cumbersome to use, as
each time one of its fields is accessed, we need to check the size.
Currently the code doesn't do that, because all of the existing
spdk_bdev_ext_io_opts fields were present when this structure was
initially introduced, but we'd need to do check the size before
accessing any new fields.
3. spdk_bdev_ext_io_opts has a metadata field, while spdk_bdev_io
already has u.bdev.md_buf, which means that we store the same thing
in several different places in spdk_bdev_io (u.bdev.md_buf,
u.bdev.ext_opts->metadata, internal.ext_opts->metadata).
Therefore, this patch removes all references to spdk_bdev_ext_io_opts
from spdk_bdev_io and replaces them with fields (memory_domain,
memory_domain_ctx) that were missing in spdk_bdev_io. Unfortunately,
this change breaks the API and requires changes in bdev modules that
supported spdk_bdev_io.u.bdev.ext_opts.

Make vbdev_crypto_destruct() return 1 to signal that program
execution should wait for spdk_bdev_destruct_done() function,
which is added inside _device_unregister_cb().
This change is related to _vdev_dev_get() not being able
to find the devices, when called from _cryptodev_sym_session_free(),
as it uses device driver name, which might already be freed.
This occurs only during bdev module finish, when crypto bdevs
are being unregistered and vbdev_crypto_finish() proceeds to
call bdev name deletion without waiting for the unregister
callbacks to complete, which ultimately results in reading
freed pointers.
This only happens when code execution takes path for DPDK 22.11+.

Currently we have stat per bdev I/O channel, but for NVMe bdev

This patch support IO stat for nvme_io_path. Record each nvme_io_path

Test on Arm server with the following basic configuration.
1 Null bdev: block size: 4K, num_blocks:16k
run bdevperf with io size=4k, qdepth=1/32/128, rw type=randwrite/mixed with 70% read/randread
Each time run 30 seconds, each item run for 16 times and get the average.

Accel modules can now implement the get_memory_domains() callback to
indicate the types of memory domains they support. If unimplemented, a
module is assumed not to support memory domains and accel will take care
of pulling/pushing data to local buffers prior to passing a task to be
executed by a module.
For now, similarly to the bdev layer, we only check if a module supports
memory domains, but we don't verify the types of the domains. That

It doesn't mean that we change the API - all function signatures are
preserved. If a function doesn't use iovecs, we use the aux_iovs array.
However, this does mean that each accel module that provides support for
a given operation will need to be adjusted to use iovecs.
Additionally, update the unit test checking copy elision to verify the
buffers of the copy operation that is left.

_bdev_nvme_submit_request() if true, or call bdev_nvme_submit_request()
otherwise. For I/O path error, clear nbdev_io->io_path for

Linux kernel native NVMe multipath already takes this approach. Hence,
this change will be reasonable.

The following patches will change I/O retry to use the same io_path if
it is still available. However, bdev_nvme_submit_request() always calls
bdev_nvme_find_io_path() first. For I/O retry, if possible, we want to
skip calling bdev_nvme_find_io_path() and use nbdev_io->io_path instead.
To reuse the code as much as possible and not to touch the fast code
path, factor out request submit functions from
bdev_nvme_submit_request() into _bdev_nvme_submit_request().
While developing this patch, a bug/mismatch was found such that
bdev_io->internal.ch was different from ch of
bdev_nvme_submit_request(). Fix it together in this patch.

Error counters for NVMe error was added in the generic bdev layer but
we want to know more detailed information for some use cases.
Add NVMe error counters per type and per code as module specific
statistics.
For status codes, the first idea was to have different named member
for each status code value. However, it was bad and too hard to test,
review, and maintain.
Instead, we have just two dimensional uint32_t arrays, and increment
one of these uint32_t values based on the status code type and status
code. Then, when dump the JSON, we use spdk_nvme_cpl_get_status_string()
and spdk_nvme_cpl_get_status_type_string().
This idea has one potential downside. This idea consumes 4 (types) *
256 (codes) * 4 (counter) = 4KB per NVMe bdev. We can make this smarter
if memory allocation is a problem. Hence we add an option
nvme_error_stat to enable this feature only if the user requests.
Additionally, the string returned by spdk_nvme_cpl_get_status_string()
or spdk_nvme_cpl_get_status_type_string() has uppercases, spaces, and
hyphens. These should not be included in JSON strings. Hence, convert
these via spdk_strcpy_replace().

This domain is meant to represent data being transformed by accel
engine. Users will be able to allocate buffers from that memory domain
and use them when appending operations to an accel sequence.
Since these buffers are only meant to be used as placeholders for actual
buffers, none of the push/pull/translate callbacks are implemented. To
access the data after it was transformed by accel, users should make
sure that the final command's destination buffer isn't allocated from
accel memory domain.

Operation sequence should always be treated as a whole, meaning that
users cannot rely on the contents of any intermediate buffers and should
only care about the buffer that's the destination of the whole
operation. This allows us to remove some of those copy operations by
changing source / destination buffer of a preceding / following
operation.
If a sequence is using buffers from non-local memory domain, users can
append a copy operation to a sequence to specify a local destination
buffer. If the module executing the operations is aware of memory
domains, this can avoid doing an extra spdk_memory_domain_pull_data().

This patch introduces the concept of chaining multiple accel operations
and executing them all at once in a single step. This means that it
will be possible to schedule accel operations at different layers of the
stack (e.g. copy in NVMe-oF transport, crypto in bdev_crypto), but
execute them all in a single place. Thanks to this, we can take
advantage of hardware accelerators that supports executing multiple
operations as a single operation (e.g. copy + crypto).
This operation group is called spdk_accel_sequence and operations can be
appended to that object via one of the spdk_accel_append_* functions.
New operations are always added at the end of a sequence. Users can
specify a callback to be notified when a particular operation in a
sequence is completed, but they don't receive the status of whether it
was successful or not. This is by design, as they shouldn't care about
the status of an individual operation and should rely on other means to
receive the status of the whole sequence. It's also important to note
that any intermediate steps within a sequence may not produce observable
results. For instance, appending a copy from A to B and then a copy
from B to C, it's indeterminate whether A's data will be in B after a
sequence is executed. It is only guaranteed that A's data will be in C.
A sequence can also be reversed using spdk_accel_sequence_reverse(),
meaning that the first operation becomes last and vice versa. It's
especially useful in read paths, as it makes it possible to build the
sequence during submission, then, once the data is read from storage,
reverse the sequence and execute it.
Finally, there are two ways to terminate a sequence: aborting or
executing. It can be aborted via spdk_accel_sequence_abort() which will
execute individual operations' callbacks and free any allocated
resources. To execute it, one must use spdk_accel_sequence_finish().
For now, each operation is executed one by one and is submitted to the
appropriate accel module. Executing multiple operations as a single one
will be added in the future.
Also, currently, only fill and copy operations can be appended to a
sequence. Support for more operations will be added in subsequent
patches.
