7bac9b06f1 nvme TCP: Make the control related pdu also allocated from the SPDK DMA memory
Purpose: To make the pdu management consistent with other PDUs, then
we can easily adapt our code into some hardware offloading solution.

864d93c053 nvmf: Add check for bidirectional xfer type
RDMA target can't handle bidirectional xfer type, in debug build
it throws an assert in nvmf_rdma_setup_wr function. NVMF controller
performs checks od opcodes, but the failure happens before this
check. Add similar validation in TCP transport.

241f290794 json_config: do not attempt to resolve JSON that failed decode
When config entry fails spdk_json_decode_object(),
that basically means incorrectly formatted JSON config.
Decode object is simple enough here - 'method' and optional 'params'.

Before this change SPDK_ERRLOG printed garbage, rather than JSON
object that failed the decode.

We actually should not do it at all:
- the object is not formatted right already
- it might be the last object, so spdk_json_next() won't work

It was not usefull, so this patch removes it.

This patch adds a pointer to io_chaneel to spdk_nvmf_rdma_qpair

operation. In this function we get io_channel from nvmf_tgt,
this channel will be used to get a thread for sending

6b41a08654 dpdkbuild: build dpdk with meson+ninja
Makefile support in DPDK was deprecated and will be removed soon,
so switch to the officially supported way of building DPDK -
with meson and ninja. Two new tools. Basically, our Makefiles
will invoke meson+ninja for DPDK, no other SPDK components are
affected.

Apparently DPDK wanted to move away from an octopus-like config
system and the ideology behind meson configuration is simple now:
build everything by default. Some PMDs can be explicitly disabled
with meson command line, but all libraries (both static and shared
versions) and test apps are built unconditionally.

How long does it take to build minimal DPDK with meson? Too much.
On my machine half of the total build time is spent on libraries
we don't need at all. (I have some hacks up my sleeve to disable
building those libraries - see the subsequent patch.) As for the

but it was rejected:

Let's not follow that direction, hack the DPDK build system instead.

As for advantages of meson+ninja over Makefiles? I can't find any.
It's another build system that does a lot for you with some functions,
magic options, and a built-in dependency system. It seems nice if you know
the syntax, but it's another component that you need to learn, debug,
and possibly find bugs in (there's a lot of github issues open for meson).
I would compare it to CMake.

As for changes in this patch: rather that explicitly disabling
PMDs we don't need, specify a list of PMDs we do need and disable
everything else found in ./dpdk/drivers/*. This way we won't have
to disable the new PMDs as they're added to DPDK.

Meson configuration also sets RTE_EAL_PMD_PATH #define to a valid directory
with built PMD shared libs. When it's set, DPDK dynamically loads all shared
libraries inside. The drivers there depend on DPDK shared libs and fail to
load in static SPDK builds, so we disable them altogether by unsetting
RTE_EAL_PMD_PATH in the meson-generated config file - just like
DPDK Makefiles did. EAL checks for RTE_EAL_PMD_PATH being empty and skips
loading any external PMDs then. We do it for both static and shared libs.
We specify all PMDs at build time for now, so there's just no need to load
them dynamically.

We have three more hacks in our submodule:
 * disable building dpdk apps by commenting-out a line in dpdk/meson.build
 * disable building unnecessary libs (build everything that spdk *may*
   need)
 * build isa-l compress pmd with `-L[...] -lisal`. DPDK expects to find
   libisal with pkg-config. We don't want to prepare a pkg-config file,
   so comment-out a failing check in another meson.build file and provide
   isa-l through CFLAGS and LDFLAGS.

We also need to make some changes to our test/external_code. First of
all, -ldpdk is no more. Meson build generates a pkg-config file with all
libs, but we'll switch to it in a separate patch - for now just specify
all -lrte_ libs one by one. -Wl,--no-as-needed has to be added to some
test cases, otherwise rte_mempool_ring isn't loaded. We don't use any
APIs from this library, it only has a static constructor that provides
a few callbacks used by rte_mempool_create(). Also, since DPDK now builds
both static and shared libraries, we need to add -Wl,-Bstatic to force
using static libswhere required. It's only needed for DPDK libs, but we
use it for SPDK libs as well since there's no harm.

As for performance:
$ ./configure --enable-debug --with-crypto --with-reduce
$ time make -j40 -C dpdkbuild all
with meson:
real    0m8.287s
user    1m7.983s
sys     0m10.548s

before, with the old DPDK makefiles:
real    0m20.232s
user    0m55.921s
sys     0m16.491s

The subsequent builds are much faster too:
$ time make -j40 -C dpdkbuild all
meson:
real    0m0.876s
user    0m0.663s
sys     0m0.217s

makefiles:
real    0m10.150s
user    0m11.740s
sys     0m6.772s

cdffd22581 env_dpdk: move NVMe PCI driver definition to the nvme lib
Now that drivers can be registered from upper layers there's
no need to keep them centralized inside env.

(check_format.sh complains that spdk_pci_nvme_get_driver() shouldn't
start with the spdk_ prefix - to workaround that we move the function
declaration from one place in env.h to another - that's enough to
convince check_format it really is a public function)

functions in every app that wants to use the accel_fw moving

instead of an accel_task combined with adding a pool of accel_tasks
in the accel_fw engine we can eliminate this.

After changing the parm to a cb_arg, changes were made to all accel_fw
interfaces to put cb_fn and cb_arg as the last parms in public and

e8e46cb615 env_dpdk/pci: remove device detach callback
You don't get notified when someone starts using your hooked
device, so there's not much gain from knowing when someone
stops.

Remove that callback and also move DPDK device detach under
the same lock which sets the pending_removal flag. This eliminates
a data race window when hotremove notification could arrive
after device was detached, but before it was scheduled to be
removed.

vmd and ioat nest the spdk_pci_device struct and abigail complains
even though the parent structs only have forward declarations in
public headers. Adding those two structs to the suppression list
doesn't help though. Abidiff still complains about the pci device
struct being changed, probably because ioat.h and vmd.h both include
env.h. Abidiff suppresion list should eventually be split per-lib,
but for now ignore struct spdk_pci_device changes globally.

/sys/bus/pci/devices/* and creates corresponding rte_pci_device-s,
then rte_bus_probe() tries to initialize each device with the
supporting driver.

Previously we did scan and probe together, one after another, now
we'll have an intermediate step. After scanning the bus, we'll
iterate through all rte_pci_device-s and temporarily blacklist any
newly detected devices. We'll use devargs->data field to a store
a timeout value (integer) after which the device can be un-blacklisted
and initialized. devargs->data is documented in DPDK as "Device
string storage" and it's a char*, but it's not referenced anywhere
in DPDK. rte_bus_probe() respects the blacklist and doesn't do
absolutely anything with blacklisted ones.

The timeout value is 2 seconds, which should be plenty enough
for an NVMe device to reset, leave the critical lock sections in
kernel, and let us initialize it safely.

Note that direct attach by BDF doesn't respect the blacklist,
so an NVMe attach RPC won't be delayed in any way, it will continue
to work as it always did. Only the automatic discovery & enumeration
is deferred.

701d17f6d6 env_dpdk/pci: ignore rte_bus_scan() errors
Extensive testing showed it can fail:
> EAL: eal_parse_sysfs_value(): cannot open sysfs value
> /sys/bus/pci/devices/0000:02:00.0/vendor
> EAL: Scan for (pci) bus failed.

spdk_pci_enumerate() would previously return with error because
of this and e.g. the test nvme hotplug app could immediately exit
with failure. A mis-timed scan shouldn't cause this kind of failure,
so ignore it's return code. This shouldn't cause any issues.

64c4fafd32 nvme/pcie: dont initiate hotremoval on SIGBUS for VFIO devices
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.
