669985172f nvme/opal: deprecate spdk_opal_supported()
The spdk_opal_supported() is redundant with spdk_opal_dev_construct(),
because we only return the spdk_opal_dev structure when the drive
can support OPAL feature.

caa9d4c87a lib/log: allow omiting filename/lineno information
In spdk_log() accept filename = NULL.
If filename is NULL then source information as well
as log level is not displayed.

This change allows to replace all usages of
printf() and fprintf(stderr,) by
SPDK_PRINTF() and SPDK_ERRLOG() which use spdk_log().

Using spdk_log() instead of printf() is always prefered
since SPDK can be used inside of another application
where SPDK logs could be redirected.

SPDK uses printf()
places where location info is not needed
we cannot replace it by SPDK_NOTICELOG().

This change is in the scope earlier planned task:

This patch also implements the new API for the 3 existing engines.
There was also some minor clean in one file, moving a function to
eliminate multiple forward declarations (there would have been
another one with this new API).

The next patch will use this API in the accel perf tool.

94345a0a1a nvme: Add the priority field in struct spdk_nvme_transport_id
Purpose: To set the priority of the NVMe-oF connection especially
for TCP connection.

For example, the previous example can be:

trtype:TCP adrfam:IPv4 traddr:10.67.110.181 trsvcid:4420

With the change, it could be:

trtype:TCP adrfam:IPv4 traddr:10.67.110.181 trsvcid:4420 priority:2

The priority is optional. We try to change
spdk_nvme_transport_id but not in spdk_nvme_ctrlr_opts since
the opts in spdk_nvme_ctrlr_opts will reflect in every nvme ctrlr,
this is short of flexibility.

Purpose: This is used to make users can specify

While creating sockets, the priority needs to be set before connect()
and listen system calls, so better to add one parameter in spdk_sock_opts
which can contain options (e.g., priority) in spdk_sock_listen_ext and
spdk_sock_connect_ext functions.

5b03dd938c module/idxd: accel framework plug-in for idxd
Docs, RPC, unit tests, etc., will follow.  Notes:

* The current implementation will only work with VFIO.

* The current implementation supports only the existing accel
framework API. The API will be expanded for DSA exclusive features
in a subsequent patch.

* SW is required to manage flow control, to not over-run the work queues.
This is provided in the accel plug-in module. The upper layers use public
API to manage this.

* As we need to support any number of channels (we can't limit ourselves
to the number of work queues) we need to dynamically size/resize our
per channel descriptor rings based on the number of current channels. This
is done from upper layers via public API into the lib.

* As channels are created, the total number of work queue slots is divided
across the channels evenly.  Same thing when they are destroyed, remaining
channels will see the ring sizes increase. This is done from upper layers
via public API into the lib.

e58e9fbda8 lib/idxd: add low level idxd library
Module, etc., will follow. Notes:

* IDXD is an Intel silicon feature available in future Intel CPUs.
Initial development is being done on a simulator. Once HW is
available and the code fully tested the experimental label will be
lifted. Spec can be found here: https://software.intel.com/en-us/download/intel-data-streaming-accelerator-preliminary-architecture-specification

* The current implementation will only work with VFIO.

* DSA has a number of engines that can be grouped based on application
need such as type of memory being served or QoS. Engines are processing
units and are assigned to groups. Work queues are on device structures
that act as front-end groups for queueing descriptors. Full details on
what is configurable & how will come in later doc patches.

* There is a finite number of work queue slots that are divided amongst
the number of desired work queues in some fashion (ie evenly).

* SW (outside of the idxd lib) is required to manage flow control, to not
over-run the work queues.This is provided in the accel plug-in module.
The upper layers use public API to manage this.

* Work queue submissions are done with a 64 byte atomic instruction

* The design here creates a set of descriptor rings per channel that match
the size of the work queues. Then, an spdk_bit_array is used to make sure
we don't overrun a queue.  If there are not slots available, the operation
is put on a linked list to be retried later from the poller.

* As we need to support any number of channels (we can't limit ourselves
to the number of work queues) we need to dynamically size/resize our
per channel descriptor rings based on the number of current channels. This
is done from upper layers via public API into the lib.

* As channels are created, the total number of work queue slots is divided
across the channels evenly. Same thing when they are destroyed, remaining
channels with see the ring sizes increase. This is done from upper layers
via public API into the lib.

* The sim has 64 total work queue entries (WQE) that get dolled out to the
work queues (WQ) evenly.

e9aec6746a lib/thread: thread_poll() polls until the exiting thread is exited
Extract _spdk_thread_exit() from spdk_thread_exit() and
_spdk_thread_poll() calls _spdk_thread_exit() if the thread is in
the exiting state. spdk_thread_exit() changes to move the state to
the exiting state. The spdk_thread_poll() loop will end after the
thread moves to the exited state because the caller of
spdk_thread_poll() will check if the thread is in the exited state,
and break the loop if true.

If the user does not call spdk_thread_exit() explicitly, the reactor
has to terminate all existing threads at its shutdown. In this case,
multiple threads may have some dependency to release I/O channels or
unregister pollers. So the reactor has the large two loops, the first
loop calls spdk_thread_exit() on all threads, the second loop calls
spdk_thread_destroy() if exited or spdk_thread_poll() otherwise for
each thread until all threads are destroyed.

Besides, change the return value of spdk_thread_exit() to return
always 0. Keep it for ABI compatibility. Change ERRLOG to INFOLOG
for _spdk_thread_exit() because it is called repeatedly now. Remove
the check of I/O reference count from _spdk_thread_exit() because
_free_thread() cannot free I/O channel. Refine the unit test
accordingly.

Fixes issue #1288.

c998c6c69e nvme: add API for qpair poll groups.
This API will allow us to simplify the polling mechanism for qpairs on a single
thread. It also will pave the way for doing transport specific aggregation of
qpair polling to increase performance.

The generic implementation is included. The transport specific calls
have yet to be implemented.

connect_io_qpair essentially allows us to split the qpair allocation process
in half which will make it possible for us to do more sophisticated things
with RDMA qpairs in poll groups. as a companion to this new API, a connect_only
option has been added to the io_qpair_opts struct which instructs alloc_io_qpair
to only allocate the qpair and not connect it.

2139be1598 lib/thread: spdk_thread_poll() measures run time per call by reading end TSC
Update spdk_thread_poll() to count SPDK thread stats correctly on multiple
SPDK threads per reactor configuration.

spdk_thread_poll() gets start time and reads TSC at end as end time,
and then gets delta between them as run time. Run time is added to idle
time or busy time according to the result of polling.

Reactor overhead is included into the next thread which calls
spdk_thread_poll() now.

spdk_thread_poll() saves the end time to the current thread to use it
as the start time of the next thread.

Unit test framework for this patch and the next patch need to access
thread->tsc_last. In the next patch, reactor will use the end time of
the current thread to the start time of the next thread in reactor_run()
to realize the idea.

Hence add an new API spdk_thread_get_last_tsc(). The corresponding
variable is named as tsc_last and it is good and is aligned with
DPDK (DPDK has used tsc_start and tsc_end as variable name). But
last_tsc will be better as API name because the last TSC value is
easier to understand.

Then add necessary unit test and update the unit test framework.

458214e2e7 nvme/opal: remove the revert asynchronous API
The revert asynchronous API doesn't run as the *real* asynchronous
way, because the drive can only support synchronous module and only
1 session is supported.  The reason why we added this API is that
RPC call has the default timeout value here, while the revert may
take over several minutes, the API itself doesn't short the revert
action, so just remove it and use the synchronous API instead.

The revert action will erase all the users data and bring the drive
back to the factory state, it should run in the synchronous mode,
so just remove the asynchronous API and we can increase the timeout
value when using RPC to call this API.

Previously the macro SN32_LT and SN32_GT had been added to iSCSI
library. But such comparisons may be used in other libraries.
So add two inline helper functions spdk_sn32_lt() and spdk_sn32_gt()
to include/spdk/util.h.

Add unit test for these functions. These functions are located in
header file but math.c is the place if they are located in source file.
Hence add unit test as the one for math.c.

The next patch replaces the macro SN32_LT and SN32_GT by
spdk_sn32_lt() and spdk_sn32_gt() in iSCSI library, respectively.

2fa51eeb46 lib/nvmf: Make spdk_nvmf_poll_group_destroy() asynchronous
The next patch will create poll group threads dynamically for
NVMe-oF target, and will need to wait for completion of poll group and
I/O channel destroy. This is a preparation for the next patch.

Add callback function and its argument to spdk_nvmf_poll_group_destroy(),
and to struct spdk_nvmf_poll_group, respectively.

The callback has not only cb_arg but also status as its parameters even
if the next patch always sets the status to zero. The reason is to follow
spdk_nvmf_tgt_destroy's callback and to process any case that the status
is nonzero in future.

spdk_nvmf_poll_group_destroy() sets the passed callback to the passed
poll group.

Then spdk_nvmf_tgt_destroy_poll_group() calls the held callback in the
end.

This change will ensure all pollers are being unregistered and
all I/O channels are being released.
