b01a393382 ioat: reduce completion writebacks
Do not set the completion_update bit except on
the last descriptor built before the dmacount doorbell
is written.  This allows much better batching of
completions (to match batching of the submissions).

c258d73feb ioat: add APIs to only build descriptors
Add spdk_ioat_build_copy and spdk_ioat_build_fill
which mirror the existing spdk_ioat_submit_copy
and spdk_ioat_submit_fill.  These new functions
*only* build the descriptors in the ring - they do
not write the doorbell.  This enables batching
which can significantly improve performance by
reducing the number of MMIO writes.

ec95646a61 ioat: make ioat_flush a public spdk_ioat_flush API
This will enable batching of doorbell writes in
future commits.  For now, just make the API public.

This is the first in a series of patches that
drastically improves performance for high queue
depth CB-DMA workloads.  Some basic tests on
my Xeon E5-v3 platform shows about 4x improvement
for 512B transfers.

5d07cfad54 vhost/scsi: handle io_channel allocation failure
We assumed io_channel allocation always succeeds, but
that's not true. Doing I/O to any vhost session that
failed to allocate an io_channel would most likely
cause a crash.

We'll now detect io_channel allocation failure and
print a proper error message. The SCSI target for
which the channel allocation failed simply won't be
visible to the vhost master. All I/O to that target
will be rejected.

We should probably report the error to the upper
layer and either prevent the device from starting
or fail the SCSI target hotplug request. But for now
let's just prevent the crash.

confusing because it does only returning macro constant
SPDK_ISCSI_MAX_RECV_DATA_SEGMENT_LENGTH.

The macro constant will be configurable and so the helper function
is not sustainable.

Replace the helper function simply by the macro constant.

2d0ce5b48b nvmf/tcp: Implement correct behavior of timeout for C2Htermreq case
From TP8000 spec 7.4.7,

"In response to a C2HTermReq PDU, the host shall terminate the connection.
If the host does not terminate the connection in an implementation specific
period that does not exceed 30 seconds, the controller may terminate the
connection on its own".

It means that the timeout is designed for: when the target is
sending out C2hTermReq, if the host does not terminate the connection,
the target should terminate the connection.

PS: For detecting the malicous connection without sending response
(such as no response of R2T PDU) which should be another patch.

70c703bb49 vtophys: add vfio no-IOMMU mode support
Currently, SPDK does not support vfio in no-IOMMU mode. However, it
seems quite easy to extend the vtophys code to add support for this.

vfio in no-IOMMU mode does not support DMA remapping. This implies that
physical DMA addresses are used instead of IOVAs.

This patch checks whether the vfio no-IOMMU mode is enabled using
function rte_vfio_noiommu_is_enabled() from the DPDK RTE vfio interface.
In this case, physical addresses are used for the DMA mappings. This is
the same code path for the DMA translations as when the uio is used as a
kernel driver.

bdc81134c2 nvmf: use io unit size in transport buffer pools
When this structure was brought up to the generic layer, the tcp
transport was using max_io_size and the rdma transport was using
io_unit_size. In the interest of conserving memory, we should use
io_unit_size instead of max_io_size.

145485769e nvmf: remove qpair state activating.
This intermediate state is unused and meaningless. the qpair transitions
into this state right before calling a synchronous operation and then
transitions to active as soon as that operation completes successfully.
If the operation did not complete successfully, we were leaving qpairs
in this weird intermediate state when for all intents and purposes they
had reverted to an uninitialized state. Keeping qpairs in the
uninitialized state until they have been added to a poll group creates a
meaningful distinction between states that can be actionable from the
transport level.

92f5548a91 rdma: properly account num_outstanding_data_wr
This value was not being decremented when we got SEND completions for
write operations because we were using the recv send to indicate when we
had completed all writes associated with the request. I also erroneously
made the assumption that spdk_nvmf_rdma_request_parse_sgl would properly
reset this value to zero for all requests. However, for requests that
return SPDK_NVME_DATA_NONE rom spdk_nvmf_rdma_request_get_xfer, this
funxtion is skipped and the value is never reset. This can cause a
coherency issue on admin queues when we request multiple log files. When
the keep_alive request is resent, it can pick up an old rdma_req which
reports the wrong number of outstanding_wrs and it will permanently
increment the qpairs curr_send_depth.

This change decrements num_outstanding_data_wrs on writes, and also
resets that value when the request is freed to ensure that this problem
doesn't occur again.
