b8c99a3aad lib: Use PRId64 for portability
POSIX defines PRId64/PRIu64/PRIx64 for printing 64-bit values in a
portable way. Replace a few references to %ld to remove the assumption
about the size of a long. Similarly, use %z with size_t arguments.

Where the value being printed is an unsigned 64-bit value, use PRIu64
instead of %ld.

Explicitly test for not __linux__ where that is the intent, rather
than testing for __FreeBSD__.

Cast pointer to uintptr_t before aligning it, rather than using
a specific integer size which may not be large enough to store a
pointer.

2e9cd9d7b0 env_dpdk/pci: fix check on 20.11 EAL API change
RTE_DEV_ALLOWED is an enum and has no associated define, hence checking
for its presence will always be false.
We could test for RTE_DEV_WHITELISTED define, but this macro added for
deprecation warning will be dropped in the future.
Switch to a check on DPDK version.

c0bf93145a env/memory: return the memory virtual address's file descriptor and offset
For virtio-user library and coming vfio-user feature, the client needs
to send the memory file descriptors to target so that the two processes
can setup shared memory region to do data processing without memory copy.
Currently virtio-user will read /proc/self/maps to get memory file descriptor,
since DPDK already provides this such APIs, so here we can just use it,
for existing virtio-user library we may replace it with the new added
API.

For the CONFIG_INTERNAL_VHOST_LIB option, SPDK doesn't

As for the vhost-nvme target, since we are developing

it now.

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
official way of building a minimal DPDK, there was a patch [1]
on dpdk mailing list to introduce more specific configuration,
but it was rejected:

> We talked about this a few times in the past, and it was actually one
> of the design goals to _avoid_ replicating the octopus-like config
> system of the makefiles. That's because it makes the test matrix
> insanely complicated, not to mention the harm to user friendliness,
> among other things.
>
> If someone doesn't want to use a PMD, they can just avoid installing it
> - it's simple enough.
>
> Sorry, but from me it's a very strong NACK.

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

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)

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.

$ abidiff [...]/libspdk_ioat.so [...]

'struct spdk_pci_device at env.h:652:1' changed:
  type size changed from 1024 to 960 (in bits)

814072fa4e env_dpdk/pci: delay device initialization on hotplug
A workaround for kernel deadlocks surfaced in #1275.

DPDK basically offers two APIs for hotplugging all PCI devices:
rte_bus_scan() and rte_bus_probe(). Scan iterates through
/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.

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.

There was a chance we scheduled a device removal to the DPDK thread
while that thread was already removing the device from a VFIO hotremove
notification (on the DPDK interrupt thread). The second hotremove
attempt touches some freed memory and segfaults.

The VFIO hotremove notification already checks pending_removal flag
under a mutex and sets it to true, so do the same in spdk_detach_rte()
(called from the SPDK init thread).

d3bcd1ca5b env_dpdk/pci: split dpdk device detach and removal
Simplify the code path a bit. VFIO notification is the only
place where detach callback is called from the dpdk intr thread.
Detach checks the current thread and behaves differently in this
case, but it could be the VFIO notification that simply calls
a different function.

So instead of carrying the VFIO notification through the generic
detach routine, carry it just through the DPDK-thread specific
subset. This lets us remove some ifs in the generic routine.

cf450c0d7c env: Add spdk_mem_reserve
The spdk_mem_reserve() function reserves a memory region in SPDK's
memory maps. This pre-allocates all of the required data structures
to hold memory address translations for that region without actually
populating the region.

After a region is reserved, calls to spdk_mem_register() for
addresses in that range will not require any internal memory
allocations. This is useful when overlaying a custom memory allocator
on top of SPDK's hugepage memory, such as tcmalloc.

5b03dd938c module/idxd: accel framework plug-in for idxd
Docs, RPC, unit tests, etc., will follow.  Notes:

* The current implementation will only work with VFIO.

* The current implementation supports only the existing accel
framework API. The API will be expanded for DSA exclusive features
in a subsequent patch.

* SW 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.

* 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 will see the ring sizes increase. This is done from upper layers
via public API into the lib.

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.

d4653a31e0 env_dpdk: dont treat NULL as error in spdk_map_bar_rte()
We use `spdk_map_bar_rte()` to read mapped addresses
from PCI BARs.
This function is currently checking for NULL in each pair.
But in PCI memory, some registers can be left unused,
in which case they are set to 0.
As a result, we may read some NULL pointers from BARs,
which is OK.
To check if given address is indeed invalid, we should first
check if it is used.
So it is best to delegate such checks to the
user of this function.
In fact, users already do the NULL check where it is needed
(ex: virtio_pci.c:390, nvme_pcie.c:589)
so this patch just removes them from `spdk_map_bar_rte()`.

This solves github issue #1206

6d6052ac96 env: Use rte_malloc in spdk_mem_register code path when possible
For TCMalloc regions which we register with spdk at runtime in the MMapHook, we
need to ensure that SPDK doesn't do any allocations in that path otherwise we
will hit a livelock situation. MmapHook is invoked when TCMalloc is out of free
memory and needs to get more memory from the system, for the hugepage case it
gets via mmap.

In the current code, we could end up calling malloc in the spdk_mem_register
call via the following call path.

spdk_mem_register -> spdk_mem_map_set_translation -> spdk_mem_map_get_map_1gb

To avoid this livelock situation we call rte_malloc instead which shouldn't
invoke the system allocator. Note that in try_expand_heap_primary() which is
invoked in the rte_malloc code path, we can still call malloc, so we need to
only use this when dynamic memory allocation is disabled via --legacy-mem.
It is possible in the future we could work around even this limitation,
but for now this implementation will be much simpler.

Have verified this change fixes the livelock condition which I was hitting in
my setup without this fix.

396c445cb1 env_dpdk: tell spdk_mem_map_init whether legacy_mem was specified
We will use this in a future patch to determine whether it's safe
to use DPDK allocated memory when allocating new 1gb page entries.

We could use it in this patch to decide whether or not to register
the memory hotplug handler, but there's really no harm registering
it even when it's not needed.

Ideally DPDK would provide some kind of API to query how DPDK was
configured.  In the normal case we know whether legacy-mem was
specified, but if users initialize DPDK themselves and then call
spdk_env_dpdk_post_init(), we won't know if legacy-mem was specified.
So in that case, we will just assume that it wasn't specified.

DPDK by default guesses that it should be using iova-mode=va
so that it can support running as an unprivileged user. However,
some systems (especially virtual machines) don't have an IOMMU capable

currently catch that. Add a check in SPDK and force iova-mode=pa

c049304a95 env: add spdk_pci_device_unclaim()
spdk_pci_device_claim() could create a file on the
filesystem that couldn't be deleted programatically.
It could only be overwritten - e.g. by another spdk
instance - but this didn't really work if that
another instance had less privileges and hence no
access to the previous file.

This is exactly the case we're seeing on our CI when
running SPDK as non-root. In general it's a good idea
not to leave any leftover files, so now we'll delete
the pci claim file when the spdk process exits.

spdk_pci_device_claim() used to return a file descriptor
that could be simply closed to "un-claim" the device.
It'll now return only a return code. The fd will be
stored inside spdk_pci_device and will be closed either
when user calls the newly introduced spdk_pci_device_unclaim(),
or when the device is detached.

We'll still need to clean up those files somewhere in
our test scripts (probably ./setup.sh cleanup) to
clean up after crashed processes or so - but we don't
necessarily want to run such scripts inside the autotest
whenever a non-root spdk is about to be started.

be04cfc342 env_dpdk/memory: aggregate adjacent vfio mappings
In the past, memory in spdk could have been unregistered in
different chunks than it was registered, so to account
for that the vtophys code used to register each hugepage
(2MB chunk of memory) separately to the VFIO driver. This
really made the code generally simple.

Now that memory in spdk can only be unregistered in the same
chunks it was registered in, we no longer have to register
each hugepage to VFIO separately. We could register the
entire memory region with just a single VFIO ioctl instead,
so that's we'll do now.

This serves as an optimization as we obviously send less
ioctls now, but most importantly it prevents SPDK from
reaching a VFIO registrations limit that was introduced
in Linux 5.1. [1]

The default limit is 65535, which results in SPDK being able to
make only the first 128GB of memory DMA-able. This is most
problematic for vhost where we need to register the memory
of all the VMs.

Fixes #915

For RHEL based distros like fedora and centos this works fine. While

1897943987 env: define minimum alignment for dma-able memory
DPDK defines the minimum alignment as "suitable for any
kind of variable (in the same manner as malloc())", but
internally the alignment is always rounded up to the
cache line size, even if the requested alignment is 0.

We would like to start relying on this behavior in FTL,
where lba maps are allocated using DMA-able memory and
are constantly looked up or modified by different threads.
By having the lba maps unaligned, we risk having those
threads pollute each other's cache lines.

Rather than enforcing this memory alignment in FTL, we
do it in spdk_*malloc directly. In general it makes
sense to have DMA-able memory always cache-line-size
aligned for the same reason as above.

We'll need to make detach synchronous again, and for that

However, device detach could be triggered from the very
same dpdk background thread as well. Waiting there would
cause a deadlock, so now we'll schedule asynchronous
device detach to the dpdk thread only if we're not on
that thread already.

This patch itself serves also as an optimization.

fe511d03d2 env_dpdk/pci: reduce g_pci_mutex scope
The global pci tailq is no longer modified on the dpdk
thread, so on the spdk thread we can access it safely
without any lock. The code is slightly more readable
then.

This shows that cleanup_pci_devices() is always wrapped
with lock/unlock. We'll put the locks inside this
function in the next patch.
