52bf2010c9 eventdev: remove software Rx timestamp
This a revert of the commit 569758758dcd ("eventdev: add Rx timestamp").
If the Rx timestamp is not configured on the ethdev port,
there is no reason to set one.
Also the accuracy  of the timestamp was bad because set at a late stage.
Anyway there is no trace of the usage of this timestamp.

75d113136f eventdev: express DLB/DLB2 PMD constraints
This commit implements the eventdev ABI changes required by
the DLB/DLB2 PMDs.  Several data structures and constants are modified
or added in this patch, thereby requiring modifications to the
dependent apps and examples.

The DLB/DLB2 hardware does not conform exactly to the eventdev interface.
1) It has a limit on the number of queues that may be linked to a port.
2) Some ports a further restricted to a maximum of 1 linked queue.
3) DLB does not have the ability to carry the flow_id as part
   of the event (QE) payload. Note that the DLB2 hardware is capable of
   carrying the flow_id.

Following is a detailed description of the changes that have been made.

1) Add new fields to the rte_event_dev_info struct. These fields allow
the device to advertise its capabilities so that applications can take
the appropriate actions based on those capabilities.

    struct rte_event_dev_info {
	uint32_t max_event_port_links;
	/**< Maximum number of queues that can be linked to a single event
	 * port by this device.
	 */

	uint8_t max_single_link_event_port_queue_pairs;
	/**< Maximum number of event ports and queues that are optimized for
	 * (and only capable of) single-link configurations supported by this
	 * device. These ports and queues are not accounted for in
	 * max_event_ports or max_event_queues.
	 */
    }

2) Add a new field to the rte_event_dev_config struct. This field allows
the application to specify how many of its ports are limited to a single
link, or will be used in single link mode.

    /** Event device configuration structure */
    struct rte_event_dev_config {
	uint8_t nb_single_link_event_port_queues;
	/**< Number of event ports and queues that will be singly-linked to
	 * each other. These are a subset of the overall event ports and
	 * queues; this value cannot exceed *nb_event_ports* or
	 * *nb_event_queues*. If the device has ports and queues that are
	 * optimized for single-link usage, this field is a hint for how many
	 * to allocate; otherwise, regular event ports and queues can be used.
	 */
    }

3) Replace the dedicated implicit_release_disabled field with a bit field
of explicit port capabilities. The implicit_release_disable functionality
is assigned to one bit, and a port-is-single-link-only  attribute is
assigned to other, with the remaining bits available for future assignment.

	* Event port configuration bitmap flags */
	#define RTE_EVENT_PORT_CFG_DISABLE_IMPL_REL    (1ULL << 0)
	/**< Configure the port not to release outstanding events in
	 * rte_event_dev_dequeue_burst(). If set, all events received through
	 * the port must be explicitly released with RTE_EVENT_OP_RELEASE or
	 * RTE_EVENT_OP_FORWARD. Must be unset if the device is not
	 * RTE_EVENT_DEV_CAP_IMPLICIT_RELEASE_DISABLE capable.
	 */
	#define RTE_EVENT_PORT_CFG_SINGLE_LINK         (1ULL << 1)

	/**< This event port links only to a single event queue.
	 *
	 *  @see rte_event_port_setup(), rte_event_port_link()
	 */

	#define RTE_EVENT_PORT_ATTR_IMPLICIT_RELEASE_DISABLE 3
	/**
	 * The implicit release disable attribute of the port
	 */

	struct rte_event_port_conf {
		uint32_t event_port_cfg;
		/**< Port cfg flags(EVENT_PORT_CFG_) */
	}

This patch also removes the depreciation notice and announce
the new eventdev ABI changes in release note.

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.

The callback can drop packets and populate a callback

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.

     -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.

cfe3aeb170 remove experimental tags from all symbol definitions
We had some inconsistencies between functions prototypes and actual
definitions.
Let's avoid this by only adding the experimental tag to the prototypes.
Tests with gcc and clang show it is enough.

339677f870 eventdev: fix Rx adapter event flush
The Rx adapter flushes events only if it has BATCH_SIZE
events buffered where BATCH_SIZE is set to 32, e.g., if a
single packet is sent, it is never passed to
eventdev. Fix this issue by adding an event buffer flush
either when a Rx queue is found to be empty or the adapter service
function has processed the max number of packets for an invocation.
