50472c44cf idxd: Do not assign the results if there is error on completion.
If there is hardware issues, we do not need to assign
the result. Because we will report the error status to the uplayer.

39827dd445 lib/idxd: Add assert check in each public API.
Those functions are exported publicly, so better to
add some assert functions to detect some null pointer
errors.

We do not use if/else check, because it is too heavy.

4a670845f8 idxd: Add a check for the batches list.
This assert is used to make sure that there is no
active batch (spdk_accel_batch) task is used.

If there are active batches found, it means that
we did not handle this case in a good manner.

f95bd3b6c7 lib/idxd: change how we complete batch desc
Previously we used a counter of our own to make sure all batch
elements plus the batch itself were done before we freed the batch.
This was due to some observations early on that the batch desc
could complete before the individual elements and a lack of clarity
as to whether this was due to the simulator or the fact that
we poll on completions and could therefore "see" completions in
a different order at that time (we were using bit arrays to poll).

Now we use an ordered (in time) list to poll locations so if we
instead put the elements on the list first and then the batch desc
itself we are assured to always "see" them in order provided the
underlying device meets spec which there's no reason to assume it
does not.

This simplifies things a bit at the same time and still assures
that we call list calbacks in order and then the batch callback
without "special" handling.

2ed914f8ea idxd: Add the kernel idxd support
This patch is used to add the kernel idxd support.

Without this patch, we can use userspace idxd driver
under accel_engine library (module/accel/idxd/accel_engine).
With this patch, we can also kernel idxd driver under the
accel_engine library.

Our approach is implementing a wrapper library to use IDXD
device by leveraging the kernel DSA driver in SPDK idxd library
(lib/idxd).

Then users can leverage the RPC later to configure how to
use the DSA device by user space driver or kernel driver.

In this patch, our approach is to use the idxd-config library
to export the WQs (Working Queues) exported by the kernel.

10808e45d4 idxd: refactor flow control for idxd engine
Recent work identified race conditions having to do with the
dynamic flow control mechanism for the idxd engine. In order
to both address the issue and simplify the code a new scheme
is now in place.  Essentially every DSA device will be allowed
to accomodate 8 channels and each channel will get a fixed 1/8
the number of work queue entries regardless of how many
channels there are.  Assignment of channels to devices is round
robin and if/when no more channels can be accommodated the get
channel request will fail.

The performance tests also revealed another issue that was
masked before, it's a one-line so is in this patch for convenience.
In the idxd poller we limit the number of completions allowed
during one run to avoid the poller thread from starving other
threads since as operations complete on this thread they are
immediately replaced up to the limit for the channel.

Was using reserved field in CRC to store the final address of where
to put the result, this not legal.  Move to the completion record
and slightly re-arrange the struct to keep it at 96 bytes.

Refacorted the IO prep function so the caller can udpate both the
descriptor and completion records instead of continuing to add
parameters to the prep function for opcodes that need something
unique in the completion record.  This also allowed for a minor
fix where the prep function was returning NULL when vtophys failed
which would have indicated busy as opposed to failire.  Now we can
proprely fail that path.

8a1a845053 idxd: simplification in re-balancing channels
For flow control reasons we have to resize the bit arrays we
use to manage flow as channels come and go.  However since
channels are assigned to devices, until the channel count
reaches the device count there's no sharing so no resize of
the array is needed. So, when we use a device for the first
time there's no need to run through the rest of the channels
and re-balance.

Same thing is done on destruction. The code to free idxd
specific resources was moved from the rebalance function to
the idxd put channel function which is a much more logical
place for it as well.

15c0e78042 lib/idxd: change config #0 to something more sane
Config #1 remains what is shown as an example in the spec. Change
config #0 to just have 1 work group and 1 work queue all backed
by 4 engines.  As the majority of initial use cases will not be
implementing separate priorities and/or different back end
targets (mem, pmem, etc) having just 1 group and work queue makes
the most sense as it allows the silicon to decide which engine to
use.

Also, having multiple work queues spreads out the available
entires such that if we're not using all of the work queues then
we're not using all of the resources.  As channels are created
they are assigned the next available device.  As a channel is
assigned a device that is already in use it will round robin
work queues.  If then, for example, we have 16 devices then only
the first work queue will ever be used for the first 16 threads
which seems and if there are even just 2 work queues per device
it would take 32 threads to use all of the resources at the
device.

By haing just one work queue per device we always have the max
number of work queue entries available regardless of how many threads
are being used.

33eac886b9 lib/idxd: refactor batching for increased performance
And to eliminate an artificial constraint on # of user descriptors.
The main idea here was to move from a single ring that covered all
user descriptors to a pre-allocated ring per pre-allocated batch.

In addition, the other major change here is in how we poll for
completions.  We used to poll the batch rings then the main ring.
Now when commands are prepared their completion address is added to
a per channel list and the poller simply runs through that list
not caring which ring the completion address belongs too. This
simplifies the completion logic considerably and will avoid
polling locations that can't potentially have a completion.

Some minor rework was included as well, mainly getting rid of the
ring_ctrl struct as it didn't serve much of a purpose anyway and
with how things are setup now its easier to read with all the
elements in the channel struct.

Also, a change that came in while this was WIP needed a few fixes
to function correctly.  Addressed those and moved them to a
helper function so we have one point of control for xlations.

Added support for NOP in cases where a batch is submitted with
only 1 descriptor.

fc250841ca idxd: add batch capability to accel framework and IDXD back-end
This patch only includes the basic framework for batching and the
ability to batch one type of command, copy. Follow-on patches will
add the ability to batch other commands and include an example of
how to do so via the accel perf tool.  SW engine support for batching
will also come in a future patch. Documentation will also be coming.

Batching allows the application to submit a list of independent
descriptors to DSA with one single "batch" descriptor. This is beneficial
when the application is in a position to have several operations ready
at once; batching saves the overhead of submitting each one separately.

The way batching works in SPDK is as follows:

1) The app gets a handle to a new batch with spdk_accel_batch_create()
2) The app uses that handle to prepare a command to be included in the
batch. For copy the command is spdk_accel_batch_prep_copy(). The
app many continue to prep commands for the batch up to the max via
calling spdk_accel_batch_get_max()
3) The app then submits the batch with spdk_accel_batch_submit()
4) The callback provided for each command in the batch will be called as
they complete, the callback provided to the batch submit itself will be
called then the entire batch is done.
