It is possible to specify io_size which is not a multiple
of sector size and in that case real IO will have size
of g_io_size_bytes/sector_size. It is integer division, so
IO will be less than requested by the user. At the same
time performance statistics are reported using io_size
specified by the user (which is bigger than real IO size)
so we have wrong statistics (e.g. we can see BW higher
than NIC line rate).
To avoid this confusing situation, add a check that
user's io_size can be evenly divided by ns sector size.

Moved this to the SW module (part of the accel engine) so the

in the tool as well.
Also, instead of using send_msg to call the completion we add it to
a list in the sw module that a new poller uses to perform the
completions as this is more efficient the sending a message to the

However when we get the capability and determine the
value of g_using_sw_engine in mulitple cases. We do not

to do test, g_using_sw_engine will not set to be false
in racing condition. Since the value of g_num_workers can be

The solution is that we check the g_using_sw_engine in

For benchmarking purposes, we may want to use a
relatively low queue depth but spread the operations
across a wider range of memory. A new -a option is
added where the user can specify an "allocate depth"
to do exactly that. In this case, more tasks (and
their associated buffers) can be allocated than we
have actual queue depth. Then when we pick a new
task for the next operation, it will use a different
memory range and avoid always using the same buffers
over and over again.
If not specified, we just allocate the same number
of tasks as the queue depth, which is the current
behavior.

The .get_zoned_model() callback is supposed to reject unsupported
file types. Right now, we do not reject unsupported file types.
For our specific ioengine, this isn't strictly needed, since our
ioengine unconditionally sets f->filetype to FIO_TYPE_BLOCK, and if
it fails to find a SPDK bdev that matches the --filename, it will
return an error that it couldn't find the bdev matching filename.
However, all .get_zoned_model() callbacks in the fio in-tree ioengines
have a check that a given file has a file type that is supported by
the ioengine itself. This is needed since they do not set f->filetype
themselves, but instead let fio generic code initialize f->filetype.
Since we reuse --filename to mean something in the SPDK namespace, we
are force to initialize filetype manually. So that is the only reason
why we know that the file type will be FIO_TYPE_BLOCK. Anyway, let's
try to keep our code as similar to the in-tree ioengines as possible.
The SPDK nvme ioengine already has this check, so adding it in the
SPDK bdev ioengine makes our ioengines more consistent as well.

fio will do certain actions depending on the backing file
type of the target that it runs against.
(E.g. if the zbd code in fio detects that the backing file
is FIO_TYPE_FILE, it will emulate zones inside the regular
file.)
Both SPDK ioengines reuse the filename option to not point
to an actual path exposed by the OS, but to instead point to
a device in the SPDK namespace.
Because of this, the file type detection in fio will fail,
and will always initialize filetype to FIO_TYPE_FILE.
Therefore, the SPDK ioengines will need to initialize
f->filetype themselves.
The SPDK nvme ioengine already initializes f->filetype to
FIO_TYPE_BLOCK unconditionally. Do the same in the SPDK
bdev ioengine.
(Just like in the SPDK nvme ioengine, we also need to call
fio_file_set_size_known(), so that fio generic code does
not try to initialize f->real_file_size.)

If our ioengine does not implement this callback, fio will always result

fio oslib implementation for this callback, e.g. FreeBSD.
On Linux, fio will by default try to parse sysfs, which will of course not

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.

Since certain options has to be saved in the struct spdk_fio_target,

Today the in-guest nvme device shows physical_block_size=512 even though
the backend iSCSI bdev supports physical_block_size=4K
iSCSI targets exposes physical block size using
logical_block_per_physical_block_exponent in READ_CAPACITY_16
NPWG is one of the way to let Linux nvme driver set
physical_block_size of the nvme block device.
This patch adds spdk_bdev.phys_blocklen which is updated if the iSCSI
backend exposes physical_block_size.
Later phys_blocklen is used in nvmf to set NPWG and NAWUPF to report
back during NS identity.
Linux driver uses min(nawupf, npwg) to set physical_block_size.
Similarly in scsi_bdev fill lbppbe in READ_CAP16 response
based on spdk_bdev.phys_blocklen.

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).

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().

spdk_fio_open(). This broke --initial_zone_reset, which needs a qpair

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.

DPDK recently clarified some semantics on the rte_devargs 'data'
and 'args' fields. This actually breaks our use of the 'data'
field to store the 2 second timeout timestamp for delaying
attach to newly inserted devices. Investigating this further,
it does not seem our use of the 'data' field was valid - it just
happened to work until now.
We could use the 'args' field now. But knowing whether to use
'args' or 'data' would then be dependent on the DPDK version.
We cannot use RTE_VERSION_NUM to decide, because this is a
compile time decision, and it is possible in shared library
use cases that we could actually link and execute against a
different version of DPDK than we built against.
So instead we will create our own env_devargs structure that
will store these allowed_at timestamps. Currently it's just
a linked list (which is exactly how DPDK does it) - we could
make it more optimal with a hash table down the road, but this
code only executes when we are doing PCI enumeration so it is
not performance critical.
Fixes#1904.

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.

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

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.
