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().

e9e97cb620 nvme/fio_plugin: fix initial_zone_reset
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 --initial_zone_reset, which needs a qpair
in order to perform the initial zone reset.

While at it, move the initial zone reset from spdk_fio_setup() to
attach_cb(), as this is where all the other fio options are verified.
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.

Since SPDK nvme ioengine no longer initializes the qpairs in .setup(),
create a temporary qpair, if the --initial_zone_reset option was used.

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.

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().

continue
* Verify 'max_open_zones' and in case of error inform the user and

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.

22a1acce97 fio_plugin/nvme: add Bit Bucket SGL with READ support
For the purpose to enable the stress test with Bit Bucket SGL,
here we added one new parameters: "bit_bucket_data_len".
For testing it, user should set "enable_sgl=1" and
"bit_bucket_data_len=4096".  This means total 4096 Bytes of
data will be described by Bit Bucket SGL, note that the value
should be less than block size specified in the fio command
line.

We will count the Bit Bucket data from the beginning of each
I/O for simplification.

Currently it's only valid for READ test. User can see the
performance improvement when enabled the Bit Bucket.

In spdk_fio_setup when the connections are too many,

poll_ctrlr function can't send the keep alive cmd which

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.

73204fe2e5 dif: Add data offset to DIF context separately from start block address
Data offset are intended to correspond to DATAO in NVMe/TCP and
Buffer Offset in iSCSI.

Previously for iSCSI, buffer offset had been merged to start block
address, but passing buffer offset separately from start block address
clarifies the logic more.

On the other hand, for NVMe/TCP, passing DATAO separately from start
block address will be critically important because DATAO will bave any
alignment and will be necessary to use for not only reference tag
but also guard computation.

This patch adds data_offset to struct spdk_dif_ctx and adds it to the
parameters of spdk_dif_ctx_init(). ref_tag_offset is also added to struct
spdk_dif_ctx and it is computed by dividing data_offset by data_block_size
and is used to compute reference tag.

The next patch will use this change when getting DIF context in SCSI.

8696cd4288 dif: Add seed value for guard to avoid 0 in case of all zero data.
Allow user to add seed value for guard compuation to DIF context.
This will avoid the guard being zero in case of all zero data.

NVMe controller doesn't support seed value for guard computation
explicitly, and hence if we want to use such a seed value in
NVMe controller, we have to format metadata more than 8 byte,
and add seed value into the reserved metadata field.

But some popular iSCSI/FC HBAs and SAS controllers have supported
seed value for guard computation, and so supporting seed value
in the SPDK DIF library is very helpful for some use cases.

Hence this patch makes the DIF library possible to specify seed
value for those use cases.

is not fixed yet. But this limitation will not be critical because
PI is located to the last 8 bytes of the metadata by default.

DIF insertion and strip will be required not to destroy data by
DIF generation. But this is still added in the TODO list even after
this patch.
