866bc6742c compressdev: add flag to specify where processing is done
A new device feature flag, RTE_COMPDEV_FF_OP_DONE_IN_DEQUEUE
is added. A PMD should set this if the bulk of the
processing is done during the dequeue. It should leave it
cleared if the bulk of the processing is done during the
enqueue (default).
Applications can use this as a hint for tuning.

2382aa8c8f cryptodev: fix driver name comparison
The string compare to the length of driver name might give false
positives when there are drivers with similar names (one being the
subset of another).

Following is such a naming which could result in false positive.
1. crypto_driver
2. crypto_driver1

When strncmp with len = strlen("crypto_driver") is done, it could give
a false positive when compared against "crypto_driver1". For such cases,
'strlen + 1' is done, so that the NULL termination also would be
considered for the comparison.

27e71c7fdc cryptodev: restore crypto op alignment and layout
in 18.08 new cache-aligned structure rte_crypto_asym_op was introduced.
As it also was included into rte_crypto_op, it caused implicit change
in rte_crypto_op layout and alignment: now rte_crypto_op is cache-line
aligned has a hole of 40/104 bytes between phys_addr and sym/asym op.
It looks like unintended ABI breakage, plus such change can cause
negative performance effects:
- now status and sym[0].m_src lies on different cache-lines, so
  post-process code would need extra cache-line read.
- new alignment causes grow of the space requirements and cache-line
  reads/updates for structures that contain rte_crypto_op inside.
As there seems no actual need to have rte_crypto_asym_op cache-line
aligned, and rte_crypto_asym_op is not intended to be used on it's own -
the simplest fix is just to remove cache-line alignment for it.
As the immediate positive effect: on IA ipsec-secgw performance increased
by 5-10% (depending on the crypto-dev and algo used).
My guess that on machines with 128B cache-line and lookaside-protocol
capable crypto devices the impact will be even more noticeable.

3e0396166b vhost: support requests only handled by external backend
External backends may have specific requests to handle, and so
we don't want the vhost-user lib to handle these requests as
errors.

This patch also changes the experimental API by introducing
RTE_VHOST_MSG_RESULT_NOT_HANDLED so that vhost-user lib
can report an error if a message is handled neither by
the vhost-user library nor by the external backend.

The logic changes a bit so that if the callback returns
with ERR, OK or REPLY, it is considered the message
is handled by the external backend so it won't be
handled by the vhost-user library.
It is still possible for an external backend to listen
to requests that have to be handled by the vhost-user
library like SET_MEM_TABLE, but the callback have to
return NOT_HANDLED in that case.

Vhost-crypto backend is also adapted to this API change.

11d5253a3e vhost: prevent disabled rings to be processed with zero-copy
The vhost-user spec says that once the vring is disabled, the
client has to stop processing it. But it can happen when
dequeue zero-copy is enabled if outstanding descriptors buffers
are still being processed by an external NIC or another guest.

The fix consists in draining the zmbufs list to ensure no more
descriptors buffers are in the wild.

Note that this fix is only working in the case REPLY_ACK
protocol feature is enabled, which is not the case by default
for now (it is only enabled when IOMMU feature is enabled in
the vhost library).

218c4e68c1 mk: use linux and freebsd in config names
Rather than using linuxapp and bsdapp everywhere, we can change things to
use the, more readable, terms "linux" and "freebsd" in our build configs.
Rather than renaming the configs we can just duplicate the existing ones
with the new names using symlinks, and use the new names exclusively
internally. ["make showconfigs" also only shows the new names to keep the
list short] The result is that backward compatibility is kept fully but any
new builds or development can be done using the newer names, i.e.  both
"make config T=x86_64-native-linuxapp-gcc" and "T=x86_64-native-linux-gcc"
work.

1598c72959 eal: fix core list validation with disabled cores
-l and -c options are two ways to select the cores used by DPDK.
Their format differs, but the checks on the selected cores are the same.
Use an intermediate array to separate the specific parsing checks from
the common consistency checks.
The parsing functions now concentrate on validating the passed string
and do nothing more.

We can report all invalid core indexes rather than only the first error.
In the error log message, reporting [0, cfg->lcore_count - 1] as a valid
range is then wrong when the core list is not continuous.

Example on my 8 cpus laptop with core 2 and 6 disabled.
echo 0 > /sys/devices/system/cpu/cpu2/online
echo 0 > /sys/devices/system/cpu/cpu6/online

Before:
./master/app/testpmd -l 0-7 --no-huge -m 512 -- --total-num-mbufs 2048
EAL: Detected 6 lcore(s)
EAL: Detected 1 NUMA nodes
EAL: invalid core list, please check core numbers are in [0, 5] range
...

After:
./master/app/testpmd -l 0-7 --no-huge -m 512 -- --total-num-mbufs 2048
EAL: Detected 6 lcore(s)
EAL: Detected 1 NUMA nodes

c3568ea376 eal: restrict control threads to startup CPU affinity
Spawning the ctrl threads on anything that is not part of the eal
coremask is not that polite to the rest of the system, especially
when you took good care to pin your processes on cpu resources with
tools like taskset (linux) / cpuset (freebsd).

Rather than introduce yet another eal options to control on which cpu
those ctrl threads are created, let's take the startup cpu affinity
as a reference and remove the eal coremask from it.
If no cpu is left, then we default to the master core.

The cpuset is computed once at init before the original cpu affinity
is lost.

Introduced a RTE_CPU_AND macro to abstract the differences between linux
and freebsd respective macros.

Examples in a 4 cores FreeBSD vm:

c19429844c vhost: remove vhost-net requirements from generic APIs
The rte_vhost API to put data into virtqueues operates
on mbufs and hence it is strictly vhost-net specific.
External backends need to implement virtqueue handling
from scratch and that's just not possible without APIs
to get/set vring base addresses.

Those relevant APIs are there, but they have a check that
prevents them from working with any non-vhost-net device.
This patch removes those checks.

rte_vhost_get_log_base() is not necessarily needed for
external backends, as other, higher level vhost APIs for
live migration are available and could be used instead.
We remove the extra check from it anyway for consistency.

e30b4e566f build: improve dependency handling
Whenever possible (if the library ships a pkg-config file) use meson's
dependency() function to look for it, as it will automatically add it
to the Requires.private list if needed, to allow for static builds to
succeed for reverse dependencies of DPDK. Otherwise the recursive
dependencies are not parsed, and users doing static builds have to
resolve them manually by themselves.
When using this API avoid additional checks that are superfluous and
take extra time, and avoid adding the linker flag manually which causes
it to be duplicated.

d23e141ffa build: set RTE_ARCH_64 based on pointer size
Rather than relying on the target machine architecture, use the
size of a pointer from the compiler to determine if we are 64-bits
or not. This allows correct behaviour when you pass -m32 as a compile
option. It also allows us to use this value repeatedly throughout the
repo rather than continually testing for the sizeof(void*).

b543d1a715 compat: merge compat library into EAL
Since compat library is only a single header, we can easily move it into
the EAL common headers instead of tracking it separately. The downside of
this is that it becomes a little more difficult to have any libs that are
built before EAL depend on it. Thankfully, this is not a major problem as
the only library which uses rte_compat.h and is built before EAL (kvargs)
already has the path to the compat.h header file explicitly called out as
an include path.

However, to ensure that we don't hit problems later with this, we can add
EAL common headers folder to the global include list in the meson build
which means that all common headers can be safely used by all libraries, no
matter what their build order.

As a side-effect, this patch also fixes an issue with building on BSD using
meson, due to compat lib no longer needing to be listed as a dependency.

054617fd82 vhost: fix deadlock in driver unregister
In rte_vhost_driver_unregister(), the connection fd is
removed from the fdset using fdset_try_del(). Call to
this function may fail if the corresponding fd is in
busy state, indicating that event dispatcher is
executing the read or write callback on this fd.
When it happens, rte_vhost_driver_unregister() keeps
trying to remove the fd from the set until it is no
more busy.

This situation is causing a deadlock, because
rte_vhost_driver_unregister() keeps trying to remove
the fd from the set with vhost_user.mutex held, while
the callback executed by the dispatcher,
vhost_user_read_cb(), also takes this mutex at
numerous places.

The fix consists in releasing vhost_user.mutex between
each retry in vhost_driver_unregister().

146e57627f eal: support strlcat function
Add the strlcat function to DPDK to exist alongside the strlcpy one.
While strncat is generally safe for use for concatenation, the API for the
strlcat function is perhaps a little nicer to use, and supports truncation
detection.

See commit 5364de644a4b ("eal: support strlcpy function") for more
details on the function selection logic, since we only should be using the
DPDK-provided version when no system-provided version is present.
