This is an attempt to workaround a kernel data race spotted in #1275.
We have to delay our VFIO interraction until after the kernel handles
the PCIe hotremoval. Otherwise we risk having a deadlock inside the
kernel. We could put a dummy delay in SPDK hotremove routine, but we
don't know exactly how long we have to wait, so wait for the VFIO
hotremove notification to arrive instead. From what I understand it
is always sent after the kerner already releases the critical locks.
This patch breaks hotremove for VFIO devices when running with
DPDK version < 18.05, but those reached EOL already and their support
is removed from SPDK later within this series.
It would be nice to wait for this VFIO notification inside lib/env_dpdk
e.g. inside the detach function, but we don't know there why the
detach is happening. It could be triggered by a user RPC, not physical
device hotremoval.

To abort requests whose cb_arg matches, add child abort request greedily.
Iterating all outstanding requests is unique for each transport but
adding child abort is common among transports, and adding child abort
is replaceable by other operations.
Hence add qpair_iterate_requests() function to the function pointer table
of transport, and pass the operation done in the iteration by a
parameter of it.
In each transport, the implementation of qpair_iterate_requests() uses
TAILQ_FOREACH_SAFE() for potential future use cases.

Each request has a callback context as cb_arg, and the callback to
nvme_complete_request() for the completed request may reuse the context
to the new request.
On the other hand, nvme_pcie_qpair_complete_tracker() dequeues tr from
pqpair->outstanding_tr after calling nvme_complete_request() for the
request pointed by tr.
Hence while nvme_complete_request() is executed, pqpair->outstanding_tr
may have two requests which has the same callback context, the
completed request and the new submitted request.
The upcoming patch will search all requests whose cb_arg matches to
abort them. In the above case, the search may find two requests by
mistake.
To avoid such error, change nvme_pcie_qpair_complete_tracker() to
dequeue tr from pqpair->outstanding_tr before calling nvme_complete_request().

physically contiguous manner:
(64db67) nvme/pcie: make sure sq and cq are physically contiguous
Using MAX_IO_QUEUE_ENTRIES is enough to make sure that either
queue does not span multiple hugepages.
Yet the patch made sure that whole page is occupied only
by the queue. Which unnecessarily increases memory consumption
up to two hugepages per each qpair.
This patch changes it so that each queue alignment is limited
up to its size.
Changes in hugepages consumed when allocating io_qpair in hello_world
application:
io_queue_size Without patch With patch
256 8MiB 0MiB
1024 12MiB 4MiB
4096 24MiB 16MiB
Note: 0MiB means no new hugepages were required and qpair fits into
previously allocated hugepages (see all steps before io_qpair
allocation in hello_world).
Intersting result of this patch is that since we required alignment
up to the hugepage size this resulted in reserving even two 2MiB
hugepages to account for DPDK internal malloc trailing element.
See alloc_sz in try_expand_heap_primary() within malloc_heap.c
This patch not only reduces overall memory reserved for the
queues, but decreases increase in heap consumption on DPDK side.

to track completion in the spdk_nvme_wait_for_completion() function.
If normal scenario a request submitted to the admin queue will be completed

spdk_nvme_wait_for_completion() calls nvme_transport_qpair_process_completions
which may return an error to the caller, the caller may exit from the
function which submitted the request and the pointer to the stack variable
will no longer be valid. Thereby the request may not be completed at that time

Use a lookup table with function pointers to build
the request depending on the payload type and SGL support.
This change helps to remove several if/else branches

Command with cns SPDK_NVME_IDENTIFY_ACTIVE_NS_LIST is issued during
controller initialization and if the controller supports SGL,
this command will be built as a contig SGL. This leads
to a failed completion with the following status:
INVALID FIELD (00/02) sqid:0 cid:95 cdw0:0 sqhd:0004 p:1 m:0 dnr:0
The first identify command SPDK_NVME_IDENTIFY_CTRLR passed since
it was built as a PRP command - we didn't know that the controller
supported SGL at that time. Fix - do not build SGL requests
for admin qpair

mapping length is initialized with 0 and spdk_vtophys() returns
min(*mapping_length, cur_size) or 0. So length -= mapping_length has no
effect and req will be failed when nseg reaches NVME_MAX_SGL_DESCRIPTORS
Initialize mapping_length = request length

The hardware sgl format can describe large contiguous
buffers using just a single element, so it's more
efficient that a prp list even for a single memory
segment. Always use the sgl format.

NVMe hotplug must be monitored in the primary process -
DPDK doesn't support trying to handle it in the
secondary process.
This issue was somewhat masked previously in secondary
processes, since usually it would just probe(NULL) which
meant probe all attached NVMe controllers. So in the
secondary process, we would probe just once, and create
the hotplug fd - it would never actually try to monitor
it.
But when explicitly specifying multiple trids in a
secondary process, probe would get called multiple
times. First time would be fine since it only creates
the hotplug fd. But second time would segfault since
monitoring for hotplug requires checking the DPDK-allocated
context which doesn't exist in the secondary process.
Fixes issue #1063.
