Batching my be resurrected in the future, but for now we need to do some

d1df8a1617 idxd: don't limit number of completions per poll
This limitation doesn't really take effect currently,
since the typical number of slots per channel isn't
bigger than MAX_COMPLETIONS_PER_POLL.  But there's
no reason for this limit anymore - we should always
poll as many completions as we find.

It's better to remove this now, in case we have
configs in the future with higher number of slots
per channel.

caa1f84e1c lib/idxd: Fix the idxd_ops resource exhaustion in chan->ops_pool
The issue is that:

We call cb_fn firstly, then add the related idxd_ops into the
chan->ops_list. Then if in user's callback, we call spdk_idxd_submit_*
function gain, then we will allocate new idxd_opts first.  So if there is
recursive spdk_idxd_submit_* in the call back function, then
we will exhaust all the ops_pool resources. And the function will
report -EBUSY issue in _idxd_prep_command function.

And this patch fixes this issue by adding back idxd_ops before calling
user's call_cb function.

When address translation failed we were not putting the op back
into the pool.  In one place also changed the return error from
translation from hardcoded value to the rc returned by the call
to be consistent with the rest of the code.

The bit arrays were used for dynamic flow control in a previous

simple lists of descriptors and completion records instead.

This is a simpler implementation and will allow for some future

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.

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.
