9854c138f7 mk: add support for mingw builds
MinGW builds require a thin layer above the standard libraries to
provide POSIX functionality that is missing on Windows. Add support
for building this.

MinGW cross builds are experimental and work is ongoing to integrate
them into the CI and test environment. Including the changes at this
stage is being done to facilitate that process.

The layer has been arranged in the same way as DPDK and is
accessed as an external build using ./configure --with-wpdk=<dir>.
Support has also been added for using a default ./wpdk in
preparation for reaching the required level of stability.

The help text for ./configure indicates that support for --with-wpdk
is experimental.

Further details and instructions can be found at https://wpdk.github.io.

91e422572a configure: add --enable-cet to build with CET support
Intel Control-flow Enforcement Technology (CET) is a
processor feature that blocks return/jump-oriented
programming (ROP) attacks.

It is currently only supported on Tiger Lake client
processors, but will be available on other processors
in the future.

CET requires toolchain support.  gcc8 does support it.
For now, this will opt-in only at least until the
technology is available on server processors.

3ff9c13614 NVMe/vfio-user: add initial version vfio-user transport to NVMe driver
When NVMf target linked with vfio-user library, we can use
vfio-user client library to connect to the target.

Here is the three examples that can work with target:

identify -r 'trtype:VFIOUSER traddr:/var/run/muser/domain/muser0/8' -g
perf -r 'trtype:VFIOUSER traddr:/var/run/muser/domain/muser0/8' -g -q 1 -o 4096 -w read -t 10
reconnect -r 'trtype:VFIOUSER traddr:/var/run/muser/domain/muser0/8' -g -q 32 -o 4096 -w randrw \
-M 50 -t 10 -c 0xE

You can run the following test script test/nvmf/target/nvmf_vfio_user.sh to have a quick test,
currently enabled with NVMe Identify,Perf,Reconnect tools.

6bd7bd0da2 vhost: deprecate internal vhost library support
The internal vhost library is used when DPDK's version
is older than 19.05 and the experiemntal vhost nvme
target.

For the CONFIG_INTERNAL_VHOST_LIB option, SPDK doesn't
enable this option by default over one year and CI
doesn't cover it either, so we may remove it with
this release.

As for the vhost-nvme target, since we are developing
a new vfio-user target solution, it's OK for us to remove
it now.

e58e9fbda8 lib/idxd: add low level idxd library
Module, etc., will follow. Notes:

* IDXD is an Intel silicon feature available in future Intel CPUs.
Initial development is being done on a simulator. Once HW is
available and the code fully tested the experimental label will be
lifted. Spec can be found here: https://software.intel.com/en-us/download/intel-data-streaming-accelerator-preliminary-architecture-specification

* The current implementation will only work with VFIO.

* DSA has a number of engines that can be grouped based on application
need such as type of memory being served or QoS. Engines are processing
units and are assigned to groups. Work queues are on device structures
that act as front-end groups for queueing descriptors. Full details on
what is configurable & how will come in later doc patches.

* There is a finite number of work queue slots that are divided amongst
the number of desired work queues in some fashion (ie evenly).

* SW (outside of the idxd lib) is required to manage flow control, to not
over-run the work queues.This is provided in the accel plug-in module.
The upper layers use public API to manage this.

* Work queue submissions are done with a 64 byte atomic instruction

* The design here creates a set of descriptor rings per channel that match
the size of the work queues. Then, an spdk_bit_array is used to make sure
we don't overrun a queue.  If there are not slots available, the operation
is put on a linked list to be retried later from the poller.

* As we need to support any number of channels (we can't limit ourselves
to the number of work queues) we need to dynamically size/resize our
per channel descriptor rings based on the number of current channels. This
is done from upper layers via public API into the lib.

* As channels are created, the total number of work queue slots is divided
across the channels evenly. Same thing when they are destroyed, remaining
channels with see the ring sizes increase. This is done from upper layers
via public API into the lib.

* The sim has 64 total work queue entries (WQE) that get dolled out to the
work queues (WQ) evenly.

To enable cross-compilation run ./configure.sh with additional --cross-prefix parameter.
The parameter should work in similar manner to DPDK CROSS parameter

Note: To cross-compile, toolchain must have SPDK dependencies such as e.g. Libaio.

2b846acc49 configure: add option not to use the internal rte_vhost copy
It's disabled by default, so no functionality is changed yet.
The intention is to use the upstream rte_vhost from DPDK,
which - starting from DPDK 19.05 - is finally capable of
running with storage device backends.

SPDK still requires a lot of changes in order to support
that upstream version, but the most fundamental change is
dropping vhost-nvme support. It'll remain usable only with
the internal rte_vhost copy and with the upstream rte_vhost
it simply won't be compiled. This allows us at least to

d1fee489a7 OCF: add OCF module
Add OCF module based on OCF meta-library
Open CAS Framwework (OCF) is high performance block storage
  caching meta-library
It is open-source, published at https://github.com/Open-CAS/ocf

With this patch OCF-enabled device is represented in SPDK
  as virtual bdev having core and caching devices as its base devices

This patch includes implementation of:
  * OCF top adapter          (vbdev_ocf.c)
  * OCF bottom adapter       (dobj.c, data.c)
  * Adaptation layer for OCF (env/)
  * OCF context abstractions (ctx.c)

Adaptation layer and context abstractions are not dependent on SPDK bdev

OCF bdev supports reads and writes, configured at startup
Other features will be added with separate patches

85bc2bbe7d configure: use mk/config.mk instead of CONFIG.local
We have hairy configuration method. First configure script uses CONFIG,
environment and arguments to produce CONFIG.local and config.h then
makefile uses CONFIG, environment and CONFIG.local to produce config.h
again. First time config.h can't be generated reliably as config.h
target in Makefile is passing MAKEFLAGS and they are unknown at
configuration phase.

Lets remove this mess by producing final mk/config.mk file and get rid
of CONFIG.local. This will also generate full build configuration in one
file instead scattering them in CONFIG and CONFIG.local.
In next patch scripts/genconfig.py can be removed.

so requiring users to specify --with-raid to configure is just

0923734c9f build: Conditionally builds single and separate shared libs
Adds option to configure script (default is disabled)
to build SPDK shared libraries, and enhances build
correspondingly to do so.  This includes the single, combined
shared library encompassing all of the SPDK static libs,
as well as production of individual SPDK shared libraries
corresponding to each of the static ones.  Although the
SPDK shared libs conform with shared lib naming conventions
complete with version numbering suffixes, this does not
confer any ABI compatibility claims whatsoever at this time.
It's merely conformance with the naming conventions.
Finally, there are no built-in dependencies between SPDK
shared libs, thus requiring one to specify all needed SPDK
shared libs to resolve all symbols in the final link of an
executable wishing to use said SPDK shared libs.

41586b0f1d bdev: add raid bdev module
Raid module:
============
- SPDK raid bdev module is a new bdev module which is
  responsible for striping various NVMe devices and expose the raid bdev
  to bdev layer which would enhance the performance and capacity.
- It can support theoretically 256 base devices (currently it is being
  tested max upto 8 base devices)
- Multiple strip sizes like 32KB, 64KB, 128KB, 256KB, 512KB etc is
  supported. Most of the current testing is focused on 64KB strip size.
- New RPC commands like "create raid bdev", "destroy raid bdev" and "get raid bdevs"
  are introduced to configure raid bdev dynamically in a running
SPDK system.
- Currently raid bdev configuration parameters are persisted in the
  current SPDK configuration file for across reboot support. DDF will be
introduced later.

High level testing done:
=======================
- Raid bdev is created with 8 base NVMe devices via configuration
  file and is exposed to initiator via existing methods. Initiator is
able to see a single NVMe namespace with capacity equal to sum of the
minimum capacities of 8 devices. Initiator was able to run raw
read/write workload, file system workload etc (tested with XFS file
system workload).
- Multiple raid bdevs are also created and exposed to initiator and
  tested with file system and other workloads for read/write IO.
- LVS / LVOL are created over raid bdev and exposed to initiator.
  Testing was done for raw read/write workloads and XFS file system
workloads.
- RPC testing is done where on the running SPDK system raid bdevs
  are created out of NVMe base devices. These raid bdevs (and LVOLs
over raid bdevs) are then exposed to initiator and IO workload was
tested for raw read/write and XFS file system workload.
- RPC testing is done for delete raid bdevs where all raid bdevs
  are deleted in running SPDK system.
- RPC testing is done for get raid bdevs where existing list of
  raid bdev names is printed (it can be all raid bdevs or only
online or only configuring or only offline).
- RPC testing is done where raid bdevs and underlying NVMe devices
  relationship was returned in JSON RPC commands
