8dd1cd2104 check_format: For C files only, fix return type breaks
In SPDK, declarations have the return type on the same line. Definitions
have the return type on a separate line. Astyle has an option for
enforcing this. Unfortunately, it seems to have two bugs:

1) It doesn't work correctly at all on C++ files.
2) It often fails on functions that return enums, or long type names

Deal with 1) by adjusting the check_format.sh script to only tell astyle
to fix return type line breaks for C files and not C++. Deal with 2) by
adding a few typedefs to work around the problem.

488570ebd4 Replace most BSD 3-clause license text with SPDX identifier.
Many open source projects have moved to using SPDX identifiers
to specify license information, reducing the amount of
boilerplate code in every source file.  This patch replaces
the bulk of SPDK .c, .cpp and Makefiles with the BSD-3-Clause
identifier.

Almost all of these files share the exact same license text,
and this patch only modifies the files that contain the
most common license text.  There can be slight variations
because the third clause contains company names - most say
"Intel Corporation", but there are instances for Nvidia,
Samsung, Eideticom and even "the copyright holder".

Used a bash script to automate replacement of the license text
with SPDX identifier which is checked into scripts/spdx.sh.

a6aaf848a5 nvme/fio_plugin: fix race during startup
We can crash with spdk_nvme_qpair_process_completions(qpair=0x0) when
called from spdk_fio_getevents(). This was observed when passing more
than two namespaces to an fio job.

This is because this callback can be called concurrently with
spdk_fio_open(), which assigns ->qpair. We'll just skip any
non-initialized qpairs in the processing loop, as eventually
spdk_fio_open() will set them.

Fixes: "f69367c78 fio_nvme: defer qpair allocation to file_open callback"

d07dc4d361 nvme/fio: free io_qpairs in close callback
If user uses the 'loops' parameter, then it will
call the open+close callbacks for each loop, but only
cleanup at the end of the entire run. Since we alloc
the io_qpair in open, but don't free them until
cleanup, we end up running out of io qpairs at some
point if we run too many loops.

So solution is to free the io qpairs in the close
callback.

5172337d95 nvme/fio_plugin: spdk_fio_get_zoned_model() is too permissive
The .get_zoned_model() callback is supposed to reject unsupported
file types. Right now, we only reject FIO_TYPE_PIPE.

However, in attach_cb() our ioengine unconditionally initializes
f->filetype to FIO_TYPE_BLOCK. This means that the only file type
that our ioengine supports is FIO_TYPE_BLOCK.

Therefore, fix spdk_get_zoned_model() to reject everything that
we do not support.

bd53d09c31 nvme/fio_plugin: remove ZBD_IGNORE usage
The define ZBD_IGNORE has been removed from upstream fio.

fio will now return an error if --zonemode=zbd is used with a
--filename that points to something that is unsupported by either
the zbd code in fio or by the ioengine itself.

ioengines are now supposed to return -EINVAL for unsupported files
(instead of returning 0 with ZBD_IGNORE for unsupported files).

This change does not need any special ifdef FIO_IOOPS_VERSION check.

6e57273783 nvme/fio_plugin: implement support for fio .get_max_open_zones callback
Implement support for the recently added fio .get_max_open_zones callback.

If our ioengine does not implement this callback, fio will always result
in an error when using --zonemode=zbd, on platforms which does not have a
fio oslib implementation for this callback, e.g. FreeBSD.

On Linux, fio will by default try to parse sysfs, which will of course not
work on SPDK.

Implement this callback so that our ioengine will be able to provide fio
with the proper max open zones limit.

This will ensure that fio will be able to fetch the proper max open zones
limit, regardless of OS.

While our SPDK nvme ioengine did overwrite the max_open_zones option if it
was set to zero, this is a bit of a hack. The new fio callback is the
proper way to inform fio about the max open zones limit, so that fio itself
can have access to the actual device limit.
(Just overwriting the requested max_open_zones option will not allow fio
to know if the requested max_open_zones option exceeds the device limit.)
Remove the SPDK specific hack and update our README.md accordingly.

The only difference is that get_fio_qpair() returns NULL if qpair->ns

Since we know that get_fio_qpair() returns NULL if qpair>ns is not set,
we can also remove the equivalent check in spdk_fio_queue().

Also use ns pointer instead of qpair->ns pointer in two other places
in spdk_fio_queue().

d69349af6b nvme/fio_plugin: fix zone_append option with multiple files per thread
Each fio thread can have multiple files that it writes to.
Which is why the per thread spdk_fio_setup() fio callback does
for_each_file() {...}.

One of these files can be e.g. a zoned namespace with append support,
another file could be a zoned namespace on another controller without
append support, and a third file could be a conventional namespace
(which never supports the zone append command).

Right now, we will return a fatal error if a thread has e.g. a zoned
namespace (with append support) together with a conventional namespace.

Instead of returning a fatal error, enable zone append only on the
namespaces that support zone append, and allow namespaces that do
not support zone append to continue as usual (using regular writes).

09dd961b35 nvme/fio_plugin: fix report_zones
Commit f69367c788 ("fio_nvme: defer qpair allocation to file_open
callback") moved the qpair allocation from spdk_fio_setup() to
spdk_fio_open(). This broke spdk_fio_report_zones(), which needs a
qpair in order to get the initial state of the zones.

setup_files() in FIO calls td->io_ops->setup() (spdk_fio_setup()),
followed by zbd_init_files(), which calls zbd_init_zone_info(),
which calls zbd_create_zone_info(), which calls parse_zone_info(),
which calls zbd_report_zones(), which calls td->io_ops->report_zones()
(spdk_fio_report_zones()).

i.e. spdk_fio_report_zones() will always be called directly after
spdk_fio_setup(). .report_zones() is even called before the per
thread ioengine .init() callback.

Therefore, spdk_fio_report_zones() is called before the ioengine
.open_file() callback.

This is done in order to ensure that all threads will share the same
zbd_info struct, which contains the per zone locks.

Since SPDK nvme ioengine no longer initializes the qpairs in .setup(),
create a temporary qpair in .report_zones().

By placing it in attach_cb(), after the duplicated file check, we
avoid the need to loop through the whole fio_thread->fio_qpair list.

f69367c788 fio_nvme: defer qpair allocation to file_open callback
All jobs are created at boot, meaning the setup callback
is invoked for all jobs before any are executed.

But it may be useful to put 'stonewall' parameters in
the job file to execute a bunch of workloads in succession,
starting one workload when the previous one completes.
But since qpairs are created currently during setup, the
total number of workloads that can be expressed is limited
since qpairs for all workloads are allocated up front.

So instead defer allocation of the io qpairs until the
file_open callback.  These don't get called until the
job associated with the 'file' (in this case, the
nvme namespace) is ready to execute.

Note that we cannot free the qpairs in the file_close
callback, since fio may 'close' the file before all
I/O have been completed.

20a01a0495 nvme/fio_plugin: use calloc to allocate zone report buffer
spdk_nvme_zns_report_zones() is implemented using
nvme_allocate_request_user_copy(), which under the hood will do
a spdk_zmalloc() with the SPDK_MALLOC_DMA flag set, and will copy
over the result to our buffer.

Therefore, it is redundant for us to use spdk_dma_zmalloc(),
because it will cause us to allocate twice the amount of memory
from the precious DMA pool than needed.

Changing this zone report buffer allocation to a calloc also
has the benefit of making the code uniform with all other
spdk_nvme_zns_report_zones() call sites in the SPDK codebase.

06ace1efbf nvme/fio_plugin: add print_qid_mappings option
print_qid_mappings=1 will now add logging messages
showing the {filename,qid} tuples associated with
each job.

Note that for the nvme plugin, the filename is
essentially the transport ID.  We just print that
filename for simplicity rather than reconstructing
a transport ID string from the ctrlr object.

17ef8ec9ac examples/nvme_fio_plugin: add support for zone append
Now when we have support for spdk_nvme_zns_zone_append() and
spdk_nvme_zns_zone_appendv(), hook them up in the nvme fio plugin.

Note that fio itself does not have support for zone append,
since unlike SPDK, there is no user facing zone append API in
Linux. Therefore, this new option simply replaces writes with
zone appends in the SPDK fio backend.

This is however still useful for the following reasons:
-Provides a way to test zone append in SPDK.
-By using zone append, we can test with iodepth > 1.

With regular writes, the user can only specify iodepth=1.
This is because for zone namespaces, writes have to target
the write pointer. Having more than one write in flight, per
zone, will lead to I/O errors.

In Linux, it is possible to use fio with iodepth > 1
on zoned namespaces, simply because of the mq-deadline
scheduler, which throttles writes such that there is only
one write in flight, per zone, even if user space has
queued up more.

Since a user might not want to use zone append unconditionally,
even on a namespace that supports it, make this an option
rather than enabling it unconditionally.

aae84b1f0e examples/nvme_fio_plugin: add plugin-option 'initial_zone_reset'
Added plugin-option 'initial_zone_reset', providing the option to reset
all zones on all namespaces with the Zoned Command Set enabled upon
initialization.
The default is not to reset. The option is exposed even when the ZBD
plumbing is not available. However, it will then inform the user that
ZBD/ZNS is not supported instead of resetting.

The plugin-option provides a short-term solution to an observed issue
with consecutive invocations of fio exhausting maximum-active-resources.
A longer-term solution would be to add a 'max_active_zones' limit in fio
and ensure that fio does not exceed that limit.

1e83b640aa examples/nvme_fio_plugin: fix zone reporting
All zone management receive helper functions (including
spdk_nvme_zns_report_zones()) are implemented to match the parameters of
the zone management receive function in the ZNS specification.

The documentation for spdk_nvme_zns_report_zones() states:
"param partial_report If true, nr_zones field in the zone report indicates
the number of zone descriptors that were successfully written to the zone
report. If false, nr_zones field in the zone report indicates the number
of zone descriptors that match the report_opts criteria."
This matches the description of the "Partial Report" bit in the ZNS spec.

Since the FIO function parse_zone_info() calls the io_ops->report_zones()
function multiple times, until all zones have been reported, it expects
the return from this function to represent the number of zones that were
successfully reported.

By setting the partial_report bit to false, the controller will return
the total number of zones, and since spdk_fio_report_zones() loops until
idx < report->nr_zones, and writes to zbdz[idx], the current code will
overwrite heap memory, since idx will take on index values that are out
of bounds for the memory allocated by the FIO function parse_zone_info().

Therefore, spdk_fio_report_zones() has to set the partial_report bit to
true when calling the NVMe level function spdk_nvme_zns_report_zones().

906c2adb86 examples/nvme_fio_plugin: help the user with max_open_zones constraints
When a device has resource-limitations such as the
maximum-open-resources (mor) and this threshold is exceeded, then IO
will fail upon completion. Such behavior is not the most user-friendly
way to tell the user that they should provide a value for the
fio-parameter 'max_open_zones'.

This change provides an arguably more user-friendly approach by checking
whether the device is limited and in case it is:

* Provide a default value for 'max_open_zones', inform the user, and
continue
* Verify 'max_open_zones' and in case of error inform the user and
return error

8a1d6f446d examples/nvme_fio_plugin: add initial support for ZNS
This adds initial support for ZNS by aligning the NVMe spec. defined ZNS
structures and commands with the fio Zone representation and
implementation of the following io-engine functions:

get_zoned_model() / spdk_fio_get_zoned_model(), when namespace is ZNS
and the Zoned-Command-Set is enabled, then this function informs fio
that the device is ZBD_HOST_MANAGED.

report_zones() / spdk_fio_report_zones(), submits a single
zone-mgmt-recv and waits for its completion, converts the spec-defined
zone-descriptors to the fio ZBD_ZONE representation and returns the
number of zones in the converted report.

reset_wp() / spdk_fio_reset_wp(), submits multiple zone-mgmt-send,
covering the range [offset, offset+length] and waits for their
completion.

Four helper-functions are added to assist in the above implementations.

get_fio_qpair(), this helper is added to retrieve the namespace matching
the given fio-file, ensuring that management commands reach the correct
namespace.

spdk_fio_qpair_mdts_nbytes(), this helper is added to assist
report_zones() retrieve the zone-report within the bounds of the
maximum-data-transfer of the device.

The functions pcu() and pcu_cb() provide a means to submit
management-commands and waiting for their completions. They are needed
since, although mgmt-send/recv are IO-commands in the context of NVMe,
then for fio they are not part of the regular queue/event/getevents but
utilized in a synchronous/blocking manner.

Note, in the fio-zone-representation, then the start/len/capacity/wp
fields are in units of bytes, whereas the corresponding values in NVMe
are in lbas/sectors. It is worth noting as the offset <-> lba
conversions do not take NVMe configurations with extended-lba format
into account. Thus, the implementation is initial support for ZNS as
more work is needed to support pi/extended-lba configurations.

Note, a guard FIO_HAS_ZBD checks for the required io-engine ops version
and indirectly testing for available of fio Zone representation by
testing for a macro introduced in the same fio-release as the required
fio Zone representation.

fcf4c5e426 bdev/fio: always set the engine_data to NULL
When initiating the io_u strcture from FIO, always
set the engine_data to NULL first as the io_u structure
is just malloced from FIO without specifically setting
to zero.

In the io_u free path, the engine_data field is checked
whether to NULL or not. To avoid mischeck issue, explicitly
set the engine_data to NULL at the beginning of the io_u
init path.

a766dd00f4 nvme/fio_plugin: Fix the issue that PRACT doesn't work when metadata size is 8 bytes
When PRACT is set, if metadata size is 8 bytes, PI is stripped
(read) or inserted (write). Hence block size must not include
metadata size for extended LBA payload. This patch fixes the issue
by reducing metadata size from block size for this case.

On the other hand, When PRACT is set, if metadata size is larger
than 8 bytes, PI is passed (read) or replaced (write). So block
size is not necessary to change for this case.

cc539da903 nvme/fio_plugin: Fix the issue that PRACT is not set in NVMe command
If PRACT is enabled, DIF context was not initialized. However it was
expected that PRACT is passed through DIF flags of the DIF context.
Hence PRACT was not set in NVMe command even if user set PRACT.

This patch fixes the issue by passing fio_qpair->io_flags instead
of dif_ctx->dif_flags.

e97148d5dd nvme/fio_plugin: Fix the issue that DIF context is initialized only for write I/O
DIF context has to be initialized both for read and write I/O. However,
it had been initialized only for write I/O unintentionally after
refining error processing.

This patch fixes the issue.

3b279697ca nvme/fio_plugin: optimize metadata buffer usage
Fio will allocate metadata buffers for each request, even the NVMe namespace
wasn't formatted to separate metadata, it's not an error to set the metadata
pointer to NVMe command, but still it's better to set it with real cases.
