b46ce57e30 example/nvme: use API to return the dlfeat.read_value
Some earlier NVMe drives don't implement Deallocate
Logical Block Feature(dlfeat) read value field, but
it can return zeroes in deallocated ranges, that's
the quirk NVME_QUIRK_READ_ZERO_AFTER_DEALLOCATE, so
here we use the API to cover earlier NVMe drives.

558be98fd3 nvme/pcie: Add statistics per poll group
Check if qpair has a poll group during the connect process,
use poll group's statistics or allocate own structure per
qpair. That is done due to not all applications use poll
groups and we want to avoid "if (qpair->group)"
conditions in data path.

Admin qpair always allocates its own statistics
structure but the statistics are not reported
since this qpair is not attached to a poll group.

Statistics are reported by spdk_nvme_perf tool
if --transport-stats and in bdev_nvme_transport_statistics
RPC method.

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.

7ce5dd62f7 nvme/identify: use calloc to allocate zone report buffer
When support for printing the zone report was added,
the zone report buffer was allocated using calloc().

This was intentionally changed to a malloc in commit
5ef79a17ec ("examples/nvme/identify: add an option to dump
the full zns zone report").

While we shouldn't need to zero the buffer, since the drive
should write  the "Number of Zones" field in zone report header,
and we should never read zone descriptors beyond this value,
the ZNS spec also states that reading beyond the last zone
descriptor has undefined results.

Considering that "Number of Zones" field in the zone report
header will only represent the number of zone descriptors
in the buffer when the partial bit was set to true,
always use calloc(), to avoid the chance that someone might
copy this code and call spdk_nvme_zns_report_zones() with the
partial bit set to false.

f6bbec8ba9 bdev/hello_world: for zoned bdevs, reset the zone before write
If the bdev is a zoned bdev, reset zone 0 (containing offset 0),
before doing the "Hello world!" write to offset 0.

This is done to ensure that the write pointer for the first zone
is at offset 0.

If we don't do a zone reset before doing the write, the write
would fail if there already were data written to the first zone.
(E.g. if the user ran the hello_bdev example twice.)

For example, you can use the following command:

./build/examples/accel_perf -C 4 -q 128 -o 4096 -t 5 -w crc32c -y

In this command, "-C 4" means that caculate the chained
crc32 for an iov array.
(even if you do not have the accelerated DSA hardware)

345bb2e89d nvme/identify: submit only one GET_FEATURE at a time
This is a workaround for issue #1799 that would require
a fix from Google Cloud Platform.  GCP NVMe SSDs do
not support overlapped GET_FEATURE commands - the
cdw0 value on completions get mixed up.

On GCP the result is that identify app reports only
1 SQ/CQ supported when in fact it supports 16.

We can easily workaround this in the identify app by
submitting one GET_FEATURE and then polling for its
completion before submitting the next one.

We may consider reverting this in the future should GCP
provide a fix, but there is really no harm in keeping
this patch long term since this isn't an I/O path issue.

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.

Add an optional limit, -z N, to the zone report dump option -z.

The variable g_zone_report_limit replaces the MAX_ZONE_DESC_ENTRIES such
that the maximum-number of zone-descriptors is overwritable. It also

e.g. "no limit" dump the full report.

The print of the section-header now includes the total amount of zones
and the limit. With this information, the header's width varies. A
helper-function, print_uline(), for printing an "underline" using a

If not, the the memory related resource allocated by the task will
not be freed.

PS: In _check_draining function, the related resource of task

f17e67059e examples/accel_perf: rework how batching is done
Previous version just used batching for initial queue depth loading
as an example of how to batch. This version adds a new param -b that
allows the caller to either disable or set a specific batch value
for use during the entire run.  For example Q depth 128 with a batch of
64 will always send IO in batches of 64 so in effect once the Q depth
has been met the tool will wait until the Q depth has dropped enough
to send another 64.  This will allow for a more accurate measurement
of batching performance vs sending IO one at a time.

Also added clarrifying note on usage the Q depth is per core, not
spread over all cores.

5ef79a17ec examples/nvme/identify: add an option to dump the full zns zone report
Add a new option, -z, to dump the full zone report for
NVMe Zoned Namepaces.

Rather than allocating a buffer that can exactly hold the number
of zones we request, allocate a fixed size buffer of size MDTS.

That way, the controller will copy as many zones as it can,
while not exceeding the buffer. The nr_zones field in the
received report indicates the number of zones that were
successfully copied to the buffer.

The full zns zone report can be larger than MDTS, therefore
we now need to put the spdk_nvme_zns_report_zones() call
inside a loop.

ac9a1a8373 examples/accel_perf: refactor task mgmt in prep for batching changes
* change how tasks are allocated and freed (simplifcation)
* added helper for getting and freeting a single task
* minor drive-by in chaning function parms for _submit_tasks()

Note that the task pool is used to manage tasks and their data
buffers.  It is fully allocated and populated before the first IO
is sent and tasks are never retired, they are re-used so they are
not removed from the list except for error or exit cleanup.

mk/spdk.lib_deps.mk which can be used to generate
the full list if the app specifies the modules and

I did a first pass through all of the existing

There may be more optimizations we can make later but
don't want to hold up this patch for all of them.

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().

12a44d4745 examples/nvme_fio_plugin: fix reset_wp()
When _reset_wp() received a range to reset, then the loop kept resetting
the first zone in the range.
Also, the processing of command-completion were re-using the same
'completion' state, thus a previous completion would short-circuit
command-completion such that it would never be processed.

This change fixes that.

Also, the reset-loop assumes that the given offset is a valid zone-start
LBA, a check is added to verify that and return -EINVAL if it is not.

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

6e231f59af examples/nvme/identify: remove exit_and_free_qpair()
Currently, error handling code in examples/nvme/identify frees the qpair
before calling exit().
However, since every SPDK process starts off by triggering a reset
(in state NVME_CTRLR_STATE_INIT), which causes all the qpairs to be
deleted, there is not really a reason to do a nice cleanup on error.

Additionally, other examples, e.g. examples/nvme/hello_world does not
do a nice cleanup on error, so it is inconsistent if identify does so.

Proper freeing of the qpairs is still done in the normal case where
we don't get any errors (in this example, and in other examples).

The printout in read_complete() says "Read I/O failed, aborting run",
however, execution still continues, and prints and prints the buffer
where the result was supposed to be stored.
Since we got a read error, we will not have gotten any data stored
in the buffer, so it is simply confusing to print it.

Calling exit() in the read_complete() error handling code code also
makes it consistent with the error handling code in write_complete()
and reset_zone_complete().

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.
