Add all necessary elements for DPDK to compile and run EAL on
LoongArch64 Soc.
This includes:
- EAL library implementation for LoongArch ISA.
- meson build structure for 'loongarch' architecture.
RTE_ARCH_LOONGARCH define is added for architecture identification.
- xmm_t structure operation stubs as there is no vector support in
the current version for LoongArch.
Compilation was tested on Debian and CentOS using loongarch64
cross-compile toolchain from x86 build hosts. Functions were tested
on Loongnix and Kylin which are two Linux distributions supported
LoongArch host based on Linux 4.19 maintained by Loongson
Corporation.
We also tested DPDK on LoongArch with some external applications,
including: Pktgen-DPDK, OVS, VPP.
The platform is currently marked as linux-only because there is no
other OS than Linux support LoongArch host currently.
The i40e PMD driver is disabled on LoongArch because of the absence
of vector support in the current version.
Similar to RISC-V, the compilation of following modules has been
disabled by this commit and will be re-enabled in later commits as
fixes are introduced:
net/ixgbe, net/memif, net/tap, example/l3fwd.

It happens because the compiler assumes that 'size'
variable in vhost_enqueue_async_packed could wrap to 0 since
'size' is uint32_t and pkt->pkt_len too.
In practice, it would never happen since 'pkt->pkt_len' is
unlikely to be close to UINT32_MAX, but let's just change
'size' to uint64_t to make the compiler happy without
having to add runtime checks.

As a part of its service function, a service usually polls some kind
of source (e.g., an RX queue, a ring, an eventdev port, or a timer
wheel) to retrieve one or more items of work.
In low-load situations, the service framework reports a significant
amount of cycles spent for all running services, despite the fact they
have performed little or no actual work.
The per-call cycle expenditure for an idle service (i.e., a service
currently without pending jobs) is typically very low. Polling an
empty ring or RX queue is inexpensive. However, since the service
function call frequency on an idle or lightly loaded lcore is going to
be very high indeed, the service function calls' cycles adds up to a
significant amount. The only thing preventing the idle services'
cycles counters to make up 100% of the available CPU cycles is the
overhead of the service framework itself.
If the RTE_SERVICE_ATTR_CYCLES or RTE_SERVICE_LCORE_ATTR_CYCLES are
used to estimate service core load, the cores may look very busy when
the system is mostly doing nothing useful at all.
This patch allows for an idle service to indicate that no actual work
was performed during a particular service function call (by returning
-EAGAIN). In such cases the RTE_SERVICE_ATTR_CYCLES and
RTE_SERVICE_LCORE_ATTR_CYCLES values are not incremented.
The convention of returning -EAGAIN for idle services may in the
future also be used to have the lcore enter a short sleep, or reduce
its operating frequency, in case all services are currently idle.
This change is backward-compatible.

Optimize service loop so that the starting point is the lowest-indexed
service mapped to the lcore in question, and terminate the loop at the
highest-indexed service.
While the worst case latency remains the same, this patch
significantly reduces the service framework overhead for the average
case. In particular, scenarios where an lcore only runs a single
service, or multiple services which id values are close (e.g., three
services with ids 17, 18 and 22), show significant improvements.
The worse case is a where the lcore two services mapped to it; one
with service id 0 and the other with id 63.
On a service lcore serving a single service, the service loop overhead
is reduced from ~190 core clock cycles to ~46, on an Intel Cascade
Lake generation Xeon. On weakly ordered CPUs, the gain is larger,
since the loop included load-acquire atomic operations.

Move the statistics from the service data structure to the per-lcore

across many lcores.
Prior to this patch, enabling statistics for a service with a
per-service function call latency of 1000 clock cycles deployed across
16 cores on a Intel Xeon 6230N @ 2,3 GHz would incur a cost of ~10000
core clock cycles per service call. After this patch, the statistics
overhead is reduce to 22 clock cycles per call.

This commit fixes a potential racey-add that could occur if
multiple service-lcores were executing the same MT-safe service
at the same time, with service statistics collection enabled.
Because multiple threads can run and execute the service, the
stats values can have multiple writer threads, resulting in the
requirement of using atomic addition for correctness.
Note that when a MT unsafe service is executed, a spinlock is
held, so the stats increments are protected. This fact is used
to avoid executing atomic add instructions when not required.
Regular reads and increments are used, and only the store is
specified as atomic, reducing perf impact on e.g. x86 arch.
This patch causes a 1.25x increase in cycle-cost for polling a
MT safe service when statistics are enabled. No change was seen
for MT unsafe services, or when statistics are disabled.

stored contiguously in the same mempool object.
User need to ensure that the mempool created in application

ensured if the pool is created after getting size of session
priv data using API rte_security_session_get_size().
Since set and get pkt metadata for security sessions are now

is added to the rte_security_session.

As per current design, rte_cryptodev_sym_session_create() and
rte_cryptodev_sym_session_init() use separate mempool objects
for a single session.
And structure rte_cryptodev_sym_session is not directly used
by the application, it may cause ABI breakage if the structure
is modified in future.
To address these two issues, the rte_cryptodev_sym_session_create
will take one mempool object that the session and session private
data are virtually/physically contiguous, and initializes both
fields. The API rte_cryptodev_sym_session_init is removed.
rte_cryptodev_sym_session_create will now return an opaque session
pointer which will be used by the app and other APIs.
In data path, opaque session pointer is attached to rte_crypto_op
and the PMD can call an internal library API to get the session
private data pointer based on the driver id.
Note: currently single session may be used by different device
drivers, given it is initialized by them. After the change the
session created by one device driver cannot be used or

During EAL init, all buses are probed and the devices found are
initialized. On eal_cleanup(), the inverse does not happen, meaning any
allocated memory and other configuration will not be cleaned up
appropriately on exit.
Currently, in order for device cleanup to take place, applications must
call the driver-relevant functions to ensure proper cleanup is done before
the application exits. Since initialization occurs for all devices on the
bus, not just the devices used by an application, it requires a)
application awareness of all bus devices that could have been probed on the
system, and b) code duplication across applications to ensure cleanup is
performed. An example of this is rte_eth_dev_close() which is commonly used
across the example applications.
This patch proposes adding bus cleanup to the eal_cleanup() to make EAL's
init/exit more symmetrical, ensuring all bus devices are cleaned up
appropriately without the application needing to be aware of all bus types
that may have been probed during initialization.
Contained in this patch are the changes required to perform cleanup for
devices on the PCI bus and VDEV bus during eal_cleanup(). There would be an
ask for bus maintainers to add the relevant cleanup for their buses since
they have the domain expertise.
