6cebe9d06b nvmf: Support physical block size if exposed by bdev
(Note: this patch was previously applied as b32cfc46 and then reverted
as 63642bef.)

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.

Fixes #1884

To enable more fine graing configuration of zero copy
send feature, add new parameters enable_zerocopy_send_server
and enable_zerocopy_send_client to spdk_sock_impl_opts to
enable/disable zcopy for specific type of sockets.
Exisiting enable_zerocopy_send parameter affects all types

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.

6c75f0a266 env_dpdk: save hotplug timeout timestamps separate from rte_devargs
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.

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.

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.)

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.
