2931a3efef event: remove 'complete' parameter from poller_register
The spdk_poller_register() function provides a way to pass an event to
call once the poller is registered, but it is always NULL in the current
code base.

6854710d6d likely.h: fix spdk_likely condition
The __builtin_expect(), as written before, would have generated the

opposite of the cond value.

We need to double-not the value to convert it to a 0/1 value while
preserving its original 0/non-zero sense.

13827a74a8 nvme: do not detach automatically on hot remove
The user's remove_cb should detach the NVMe controller when it can
ensure that it is no longer in use.  In the interim (between remove_cb
and spdk_nvme_detach()), the controller will remain in a failed state,
so any new I/O submissions will return an error code but not crash.

examples/nvme/hotplug is not yet updated for this change, but that will
be done in a separate patch.

based on an enum of specific device types, it is not useful to query the

It is currently unused and does not work in its current form on FreeBSD
(it reads a file from /sys).  This lets us drop a big chunk of file
reading and parsing code.

f30f0c76f1 scsi: refactor usage of iov from spdk_scsi_task
This patch is preparation for fixing alloc_len overrun in SENSE 6/10 and
READCAP 6/10. To simplify code forbid usage of iov outside of
scsi/task.c.

This also drop SPDK_SCSI_TASK_ALLOC_BUFFER flag that obfuscate code. As
a replacement assume that if field alloc_len is non zero it mean that
iov.buffer is internally allocated. Functions
spdk_scsi_task_free_data(), spdk_scsi_task_set_data() and
spdk_scsi_task_alloc_data() manage this field.

0aec36be1f nvme: return virtual address in SGL callback
Instead of the next_sge callback returning the physical address
directly, make it return the virtual address and convert to physical
address inside the NVMe library.

This is necessary for NVMe over Fabrics host support, since the RDMA
userspace API requires virtual addresses rather than physical addresses.
It is also more consistent with the normal non-SGL NVMe functions that
already take virtual addresses.

52bbb267d8 event: process events in batches
Since we are usually going to be removing multiple events from the queue
at once, use the DPDK burst dequeue interface to improve efficiency.

Also rework the event queue runner to always process a fixed maximum
number of events per timeslice for simplicity.  This removes the
rte_ring_count() call from the hot path and improves fairness between
events and pollers.

Now that events are dequeued in bulk, we can also put the event objects
back into the mempool in bulk.  Add an env wrapper around
rte_mempool_put_bulk() and use it to free all of the events at once.

Basic performance benchmark using test/lib/event/event/event -t 10
is improved: previously ~40 million events per second, now ~46 million
events per second.

fcb00f3780 nvme: expand probe information to a struct
spdk_nvme_probe() will now provide a struct spdk_nvme_probe_info to the
probe and attach callbacks in place of the PCI device pointer.

This struct contains the useful information that could be retrieved from
the PCI device during probe.

The goal of this change is to allow expansion of the probe information
in the future when other transports (specifically, NVMe over Fabrics)
are added that do not necessarily use PCI addressing or device IDs.

- Split the part that gets a PCI device's address into its own function,
  spdk_pci_device_get_addr(). This is useful outside of the comparison
  function and is orthogonal to comparing addresses.
- Make the comparison function take two addresses instead of a device
  and an address.  The more general form will be useful with addresses
  that are not directly associated with a device.  Because of this, also
  rename the function from spdk_pci_device_compare_addr() to
  spdk_pci_addr_compare().
- Return a signed value similar to strcmp() so that addresses can be
  ordered, not just compared for equality.

Our generic pci interface is now hidden behind include/spdk/pci.h
and implemented in lib/util/pci.c. We no longer wrap the calls
in nvme_impl.h or ioat_impl.h. The implementation now only uses
DPDK and the libpciaccess dependency has been removed. If using
a version of DPDK earlier than 16.07, enumerating devices
by class code isn't available and only Intel SSDs will be
discovered. DPDK 16.07 adds enumeration by class code and all
NVMe devices will be correctly discovered.

0babf8ce81 bdev, copy: move all I/O paths to use I/O channels
bdev and copy modules no longer have check_io functions
now - all polling is done via pollers registered when
I/O channels are created.

Other default resources are also removed - for example,
a qpair is no longer allocated and assigned per bdev
exposed by the nvme driver - the qpairs are only allocated
via I/O channels.  Similar principle also applies to the
aio driver.

ioat channels are no longer allocated and assigned to
lcores - they are dynamically allocated and assigned
to I/O channels when needed.  If no ioat channel is
available for an I/O channel, the copy engine framework
will revert to using memcpy/memset instead.

ee66e58e0a util: add spdk_thread and spdk_io_channel
This patch adds a basic framework for creating I/O channels
for I/O devices.  An spdk_io_channel represents a one-to-one
mapping between a calling thread (represented by spdk_thread)
and an I/O device that the thread will perform I/O operations
on.
