3cc6ecfdfe build: remove makefiles
A decision was made [1] to no longer support Make in DPDK, this patch
removes all Makefiles that do not make use of pkg-config, along with
the mk directory previously used by make.

4f86c0ba19 version: 20.11-rc0
Start a new release cycle with empty release notes.

The ABI version becomes 21.0.
The ABI major is back to normal, having only one number (21 vs 20.0).
The map files are updated to the new ABI major number (21).
The ABI exceptions are dropped.
Travis ABI check is disabled because compatibility is not preserved.

030c216411 eventdev: relax SMP barriers with C11 atomics
The impl_opaque field is shared between the timer arm and cancel
operations. Meanwhile, the state flag acts as a guard variable to
make sure the update of impl_opaque is synchronized. The original
code uses rte_smp barriers to achieve that. This patch uses C11
atomics with an explicit one-way memory barrier instead of full
barriers rte_smp_w/rmb() to avoid the unnecessary barrier on aarch64.

Since compilers can generate the same instructions for volatile and
non-volatile variable in C11 __atomics built-ins, so remain the volatile
keyword in front of state enum to avoid the ABI break issue.

1028d63eb2 eventdev: use C11 atomics for lcore timer armed flag
The in_use flag is a per core variable which is not shared between
lcores in the normal case and the access of this variable should be
ordered on the same core. However, if non-EAL thread pick the highest
lcore to insert timers into, there is the possibility of conflicts
on this flag between threads. Then the atomic compare-and-swap
operation is needed.

Use the C11 atomics instead of the generic rte_atomic operations to
avoid the unnecessary barrier on aarch64.

aceb737d6f eventdev: fix race condition on timer list counter
The n_poll_lcores counter and poll_lcore array are shared between lcores
and the update of these variables are out of the protection of spinlock
on each lcore timer list. The read-modify-write operations of the counter
are not atomic, so it has the potential of race condition between lcores.

Use c11 atomics with RELAXED ordering to prevent confliction.

fbaf943887 build: remove individual library versions
Since the library versioning for both stable and experimental ABI's is
now managed globally, the LIBABIVER and version variables no longer
serve any useful purpose, and can be removed.

The replacement in Makefiles was done using the following regex:

	^(#.*\n)?LIBABIVER\s*:=\s*\d+\n(\s*\n)?

(LIBABIVER := numbers, optionally preceded by a comment and optionally
succeeded by an empty line)

The replacement for meson files was done using the following regex:

	^(#.*\n)?version\s*=\s*\d+\n(\s*\n)?

(version = numbers, optionally preceded by a comment and optionally
succeeded by an empty line)

[David]: those variables are manually removed for the files:
- drivers/common/qat/Makefile
- lib/librte_eal/meson.build
[David]: the LIBABIVER is restored for the external ethtool example
library.

68d21669f3 eventdev: change Rx adapter callback and stats structure
Replace the mbuf pointer array in the event eth Rx adapter
callback with an event array. Using an event array allows
the application to change attributes of the events enqueued
by the SW adapter.

The callback can drop packets and populate a callback
argument with the number of dropped packets. Add a Rx adapter
stats field to keep track of the total number of dropped packets.

This commit removes the experimental tags from
the callback and stats APIs, the experimental tag from eventdev
is also removed and eventdev functions become part of the
main DPDK API/ABI.

cc7b73ea9e eventdev: add new software timer adapter
This patch introduces a new version of the event timer adapter software
PMD. In the original design, timer event producer lcores in the primary
and secondary processes enqueued event timers into a ring, and a
service core in the primary process dequeued them and processed them
further.  To improve performance, this version does away with the ring
and lets lcores insert timers directly into timer skiplist data
structures; the service core directly accesses the lists as well, when
looking for timers that have expired.

To compare the burst and non-burst performance of the original and new
versions of the software event timer adapter, I ran the following
commands:

$ sudo ./build/app/dpdk-test-eventdev -c 0xFFE -s 0xC --vdev=event_sw0 \
-- --test=perf_queue --plcores=4,5,6 --wlcore=7,8,9 --stlist=p \
--prod_type_timerdev --worker_deq_depth=32

$ sudo ./build/app/dpdk-test-eventdev -c 0xFFE -s 0xC --vdev=event_sw0 \
-- --test=perf_queue --plcores=4,5,6 --wlcore=7,8,9 --stlist=p \
--prod_type_timerdev_burst --worker_deq_depth=32

With the new version, I see a 151% improvement in throughput for the
non-burst case, and a 270% improvement in throughput for the burst case.
I also see a 53% improvement in arm latency in the non-burst case and a
65% improvement in arm latency in the burst case.

Note: To perform the test,  I commented out a check in the original
version that checks the adapter tick interval against a minimum value.

18218713bf enforce experimental tag at beginning of declarations
Putting a '__attribute__((deprecated))' in the middle of a function
prototype does not result in the expected result with gcc (while clang
is fine with this syntax).

$ cat deprecated.c
void * __attribute__((deprecated)) incorrect() { return 0; }
__attribute__((deprecated)) void *correct(void) { return 0; }
int main(int argc, char *argv[]) { incorrect(); correct(); return 0; }
$ gcc -o deprecated.o -c deprecated.c
deprecated.c: In function ‘main’:
deprecated.c:3:1: warning: ‘correct’ is deprecated (declared at
deprecated.c:2) [-Wdeprecated-declarations]
 int main(int argc, char *argv[]) { incorrect(); correct(); return 0; }
 ^

Move the tag on a separate line and make it the first thing of function
prototypes.
This is not perfect but we will trust reviewers to catch the other not
so easy to detect patterns.

sed -i \
     -e '/^\([^#].*\)\?__rte_experimental */{' \
     -e 's//\1/; s/ *$//; i\' \
     -e __rte_experimental \
     -e '/^$/d}' \
     $(git grep -l __rte_experimental -- '*.h')

Special mention for rte_mbuf_data_addr_default():

There is either a bug or a (not yet understood) issue with gcc.
gcc won't drop this inline when unused and rte_mbuf_data_addr_default()
calls rte_mbuf_buf_addr() which itself is experimental.
This results in a build warning when not accepting experimental apis
from sources just including rte_mbuf.h.

For this specific case, we hide the call to rte_mbuf_buf_addr() under
the ALLOW_EXPERIMENTAL_API flag.

bdc2f5cf71 eventdev: add experimental tag back for Rx adapter
Add the experimental tag back to the Rx event adapter callback,
the Rx event callback register and the Rx event adapter statistics
retrieval functions due to an API change to be proposed in a
future patch.

This patch also adds the experimental tag to these
function definitions and adds the functions to the EXPERIMENTAL
section of the map file, these were missing previously.

auto-generated via command:

5d3f721009 mbuf: implement generic format for sched field
This patch implements the changes proposed in the deprecation
notes [1][2].

librte_mbuf changes:
The mbuf->hash.sched field is updated to support generic
definition in line with the ethdev traffic manager and meter APIs.
The new generic format contains: queue ID, traffic class, color.

Added public APIs to set and get these new fields to and from mbuf.

librte_sched changes:
In addtion, following API functions of the sched library have
been modified with an additional parameter of type struct
rte_sched_port to accommodate the changes made to mbuf sched field.
(i)rte_sched_port_pkt_write()
(ii) rte_sched_port_pkt_read_tree_path()

librte_pipeline, qos_sched UT, qos_sched app are updated
to make use of new changes.

Also mbuf->hash.txadapter has been added for eventdev txq,
rte_event_eth_tx_adapter_txq_set and rte_event_eth_tx_adapter_txq_get()
are updated to use mbuf->hash.txadapter.txq.

doc:
Release notes updated.
Removed deprecation notice for mbuf->hash.sched and sched API.

rte_event_eth_tx_adapter_queue_del() - remove the

queues added to the adapter which maybe different
from the current ethdev queue count.
