The meson.build files in each example directory is simply to support
building the example as part of the main SDK build, and these should not
be installed with the example's source code and makefile. The exclude of
"meson.build" only filters out the top-level examples/meson.build file,
not the file in each subdirectory.
To fix this, we can build up the list of files to exclude based off the

returns no hits when run on an installed instance.

Move eth stop code from "signal_handler" function to the end of "main"
function. There are two reasons for this:
First, this improves code maintenance and makes code look simple and
clear. Based on this change, after receiving the interrupt signal,
"fdata->done" is set as 1. Then the main thread will wait all worker
lcores to jump out of the loop. Finally, the main thread will stop and
then close eth dev port.
Second, for older version, the main thread first stops eth dev port and
then waits the end of worker lcore. This may cause errors because it may
stop the eth dev port which worker lcores are using. This moving change
can fix this by waiting all worker threads to exit and then stop the
eth dev port.
In the meanwhile, remove wmb in signal_handler.
This is because when the main lcore receive the stop signal, it stores 1
into fdata->done. And then the worker lcores load "fdata->done" and jump
out of the loop to stop running. Nothing should be stored after updating
fdata->done, so the wmb is unnecessary.

When the main core is set as tx/rx/sched/worker core, it also needs to
print some information to show this. Thus, add info output for the main
core, and add a "dump" function to print core information for the sake
of code simplicity and easy maintenance.
In the meanwhile, fix the count error. For the variable "worker_idx", it
should be incremented when the core is set as worker core. However, when
the main core is set as rx/tx/sched core, the worker_idx is also
incremented. Though this error may not have a substantial impact due to
that the main core is the last launched core, but it should be corrected
from the perspective of code correctness.

In the case that the cores are isolated, if "-l" or "-c" parameter is not
added, the cores will not be enabled and can not launch worker function
correctly. In the meanwhile, no error information is reported.
For example:
totally CPUs:16
isolated CPUs:1-8
command: sudo gdb -args ./dpdk-eventdev_pipeline --vdev event_sw0 \
-- -r1 -t1 -e4 -w F00 -s4 -n0 -c32 -W1000 -D

ROLE_OFF, ROLE_OFF, ROLE_OFF, ROLE_OFF,
ROLE_OFF, ROLE_RTE, ROLE_RTE, ROLE_RTE,
ROLE_RTE, ROLE_RTE, ROLE_RTE, ROLE_RTE}
output information:
...
[main()] lcore 9 executing worker, using eventdev port 0
[main()] lcore 10 executing worker, using eventdev port 1
[main()] lcore 11 executing worker, using eventdev port 2
This is because "RTE_LCORE_FOREACH_WORKER" chooses the enabled core. In
the case that the cores are isolated, "the lcore_role" flag of isolated
cores are set as "ROLE_OFF" by default(not enabled). So if we choose
these isolated cores as workers, "RTE_LCORE_FOREACH_WORKER" will ignore
these cores and not launch worker functions on them.
To fix this, add "-l" parameters to doc and add lcore enabled check.

Async enqueue offloads large copies to DMA devices, and small copies
are still performed by the CPU. However, it requires users to get
enqueue completed packets by rte_vhost_poll_enqueue_completed(), even
if they are completed by the CPU when rte_vhost_submit_enqueue_burst()
returns. This design incurs extra overheads of tracking completed
pktmbufs and function calls, thus degrading performance on small packets.
This patch enhances async enqueue for small packets by enabling
rte_vhost_submit_enqueue_burst() to return completed packets.

Once it has been determined that an example cannot be built, there is
little point in continuing to process the meson.build file for that
example, so we can use subdir_done() to return to the calling file.

Two warnings are reported by gcc 9.3.0 on Ubuntu 20.04.
When producing a printable mac address the buffer was appropriately sized
for holding the mac address exactly, but the actual snprintf included a
'\n' character at the end, which means that the snprintf technically is
getting truncated i.e. the \n would not be added due to lack of space.
This gets flagged as a problem by modern versions of gcc, e.g. on Ubuntu
20.04.
main.c:77:37: warning: ‘__builtin___snprintf_chk’ output truncated
before the last format character [-Wformat-truncation=]
77 | "%02x:%02x:%02x:%02x:%02x:%02x\n",
| ^
Since the \n is getting stripped anyway, we can fix the issue by just
removing it. In the process we can switch to using the standard ethernet
address formatting function from rte_ether.h.
The other warning is about possible string truncation when getting the
RX queue name:
In file included from init.c:36:
init.c: In function ‘init’:
../shared/common.h:38:28: warning: ‘%u’ directive output may be truncated
writing between 1 and 10 bytes into a region of size 8
[-Wformat-truncation=]
38 | #define MP_CLIENT_RXQ_NAME "MProc_Client_%u_RX"
| ^~~~~~~~~~~~~~~~~~~~
../shared/common.h:52:35: note: in expansion of macro ‘MP_CLIENT_RXQ_NAME’
52 | snprintf(buffer, sizeof(buffer), MP_CLIENT_RXQ_NAME, id);
| ^~~~~~~~~~~~~~~~~~
This is a false positive, as the value of the "id" is limited to 255,
being stored in the app as a uint8_t value, removing the possibility of
the %u being replaced by anything other then 3 characters max (rather than
up to 10 as thought by the compiler). Therefore, the warning can be easily
removed by changing the type of the "id" parameter to the local function
from "unsigned" to "uint8_t" also, ensuring the compiler is aware of the
range limit.

As discussed on the dpdk-dev mailing list[1], we can make some easy
improvements in standardizing the naming of the various components in DPDK,
and their associated feature-enabled macros.
Following this patch, each library will have the name in format,
'librte_<name>.so', and the macro indicating that library is enabled in the
build will have the form 'RTE_LIB_<NAME>'.
Similarly, for libraries, the equivalent name formats and macros are:
'librte_<class>_<name>.so' and 'RTE_<CLASS>_<NAME>', where class is the
device type taken from the relevant driver subdirectory name, i.e. 'net',
'crypto' etc.
To avoid too many changes at once for end applications, the old macro names
will still be provided in the build in this release, but will be removed
subsequently.

The API ``rte_security_session_create`` takes only single
mempool for session and session private data. So the
application need to create mempool for twice the number of
sessions needed and will also lead to wastage of memory as
session private data need more memory compared to session.
Hence the API is modified to take two mempool pointers
- one for session and one for private data.
This is very similar to crypto based session create APIs.

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
/**

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