3c3328aef3 eventdev/eth_tx: add queue start/stop API
Add support to start or stop a particular queue
that is associated with the adapter.

Start function enables the Tx adapter to start enqueueing
packets to the Tx queue.

Stop function stops the Tx adapter from enqueueing any
packets to the Tx queue. The stop API also frees any packets
that may have been buffered for this queue. All in-flight packets
destined to the queue are freed by the adapter runtime until the
queue is started again.

0fbb55efa5 eventdev: add element offset to event vector
Add `rte_event_vector:elem_offset:12` bit field event vector
structure the bits are taken from `rte_event_vector::rsvd:15`.
The element offset defines the offset into the vector array
at which valid elements start.

The valid elements count will be equal to
`rte_event_vector::nb_elem`.

Update Rx/Tx adapter SW implementation to use elem_offset.

fbb9f7e215 eventdev/eth_tx: fix adapter stop
adapter_stop function is stopping the adapter service using
rte_service_runstate_set() API and waiting until
rte_service_may_be_active() API returns stopped state in an
infinite loop.

This results in hang issues if application calls
rte_service_lcore_stop() before adapter stop.

Remove the state check after setting the service state which
avoids running into hang issues. This also makes Tx adapter stop
inline with remaining adapters.

0f3d92f373 telemetry: eliminate duplicate code for json output
When preparing the json response to a telemetry socket query, the code
for prefixing the command name, and appending the file "}" on the end of
the response was duplicated for multiple reply types. Taking this code
out of the switch statement reduces the duplication and makes the code
more maintainable.

For completeness of testing, add in a test case to validate the "null"
response type - the only leg of the switch statement not already covered
by an existing test case in the telemetry_data tests.

For string values returned from telemetry, escape any values that cannot
normally appear in a json string. According to the json spec[1], the
characters than need to be handled are control chars (char value < 0x20)

To handle this, we replace the snprintf call with a separate string
copying and encapsulation routine which checks each character as it
copies it to the final array.

1c9a7fba5c net: accept unaligned data in checksum routines
__rte_raw_cksum() (used by rte_raw_cksum() among others) accessed its
data through an uint16_t pointer, which allowed the compiler to assume
the data was 16-bit aligned. This in turn would, with certain
architectures and compiler flag combinations, result in code with SIMD
load or store instructions with restrictions on data alignment.

This patch keeps the old algorithm, but data is read using memcpy()
instead of direct pointer access, forcing the compiler to always
generate code that handles unaligned input. The __may_alias__ GCC
attribute is no longer needed.

The data on which the Internet checksum functions operates are almost
always 16-bit aligned, but there are exceptions. In particular, the
PDCP protocol header may (literally) have an odd size.

Performance impact seems to range from none to a very slight
regression.

f8f6b1c174 vhost: stop using mempool for IOTLB cache
A mempool consumes 3 memzones (with the default ring mempool driver).
The default DPDK configuration allows RTE_MAX_MEMZONE (2560) memzones.

Assuming there is no other memzones that means that we can have a
maximum of 853 mempools.

In the vhost library, the IOTLB cache code so far was requesting a
mempool per vq, which means that at the maximum, the vhost library
could request mempools for 426 qps.

This limit was recently reached on big systems with a lot of virtio
ports (and multiqueue in use).

While the limit on mempool count could be something we fix at the DPDK
project level, there is no reason to use mempools for the IOTLB cache:
- the IOTLB cache entries do not need to be DMA-able and are only used
  by the current process (in multiprocess context),
- getting/putting objects from/in the mempool is always associated with
  some other locks, so some level of lock contention is already present,

We can convert to a malloc'd pool with objects put in a free list
protected by a spinlock.

68b95704a6 pipeline: add API for shared library-based pipeline build
Previously, the pipeline build operation was done based on the
specification file (typically produced by the P4 compiler), then the C
code with optimized functions for the pipeline actions and
instructions was generated, built into a shared object library, loaded
and installed into the pipeline in a completely hardcoded and
non-customizable way.

Now, this process is split into three explicit stages:
i) code generation (specification file -> C file);
ii) code build (C file -> shared object library);
iii) code installation (library load into the pipeline).

bdf2f895a6 gro: fix identifying fragmented packets
A packet with RTE_PTYPE_L4_FRAG(0x300) contains both RTE_PTYPE_L4_TCP
(0x100) & RTE_PTYPE_L4_UDP (0x200). A fragmented packet as defined in
rte_mbuf_ptype.h cannot be recognized as other L4 types and hence the
GRO layer should not use IS_IPV4_TCP_PKT or IS_IPV4_UDP_PKT for
RTE_PTYPE_L4_FRAG. Hence, if the packet type is RTE_PTYPE_L4_FRAG the
IP header should be parsed to recognize the appropriate IP type and
invoke the respective gro handler.

This commit fixes an issue where calling rte_service_lcore_stop()

The stale status would result in rte_service_may_be_active() always
returning "1", indicating that the service is not certainly stopped.

This is fixed by ensuring the "active on lcore" status of each service
is set to 0 when an lcore is stopped.

36c525a035 vhost: prefix logs with context
We recently improved the log messages in the vhost library, adding some
context that helps filtering for a given vhost-user device.
However, some parts of the code were missed, and some later code changes
broke this new convention (fixes were sent previous to this patch).

Change the VHOST_LOG_CONFIG/DATA helpers and always ask for a string
used as context. This should help limit regressions on this topic.

Most of the time, the context is the vhost-user device socket path.
For the rest when a vhost-user device can not be related, generic
names were chosen:
- "dma", for vhost-user async DMA operations,
- "device", for vhost-user device creation and lookup,
- "thread", for threads management,

In the virtio blk vDPA live migration use case, before the live
migration process, QEMU will set call fd to vDPA back-end. QEMU
and vDPA back-end stand by until live migration starts.
During live migration process, QEMU sets kick fd and a new call
fd. However, after the kick fd is set to the vDPA back-end, the
vDPA back-end configures device and data path starts. The new
call fd will cause some kind of "re-configuration", this kind
of "re-configuration" cause IO drop.
After this patch, vDPA back-end configures device after kick fd
and call fd are well set and make sure no IO drops.

0efcd352e2 eal/unix: make stack dump signal safe
rte_dump_stack() needs to be usable in situations when a bug is
encountered and from signal handlers (such as SEGV).

Glibc backtrace_symbols() calls malloc which makes it
dangerous in a signal handler that is handling errors that maybe
due to memory corruption. Additionally, rte_log() is unsafe because
syslog() is not signal safe; printf() is also documented as
not being safe.

This version formats message and uses writev for each line in a manner
similar to what glibc version of backtrace_symbols_fd() does. The
FreeBSD version of backtrace_symbols_fd() is not signal safe.

Sample output:

0: ./build/app/dpdk-testpmd (rte_dump_stack+0x2b) [560a6e9c002b]

Subsequent calls to copy_data in the library were then failing.
Fix this by incrementing the descriptor only if there is some left data
to copy.

When received from another Vhost-user port, the packet
checksum might already contain the pseudo-header checksum
but we have no way to know it. So we have no other choice
than doing the pseudo-header checksum systematically.

The service data pointer storage for txa_service_data_array is

Initialization of this memory causes buffer overflow and result in

  EAL: FATAL: Cannot init trace

The root cause it that the offset set wrong with long file-prefix and
then lead the strftime return failed.

At the same time, trace_session_name_generate() uses errno as the return
value, but the errno was not set if strftime returned zero.
A previously set errno (EEXIST or ENOENT from call to mkdir for creating
the runtime configuration directory) was returned in this case.
This is fragile and may lead to incorrect logic if errno was set
to 0 previously.
This also resulted in inaccurate prompting.
Set errno to ENOSPC if strftime return zero.

The cmdline library cmdline_parse() function parses a command and
executes the action automatically too. The cmdline_valid_buffer function
also uses this function to validate commands, meaning that there is no
function to validate a command as ok without executing it.

To fix this omission, we extract the body of cmdline_parse into a new
static inline function with an extra parameter to indicate whether the
action should be performed or not. Then we create two wrappers around
that - a replacement for the existing cmdline_parse function where the
extra parameter is "true" to execute the command, and a new function
"cmdline_parse_check" which passes the parameter as "false" to perform
cmdline validation only.

f22e705ebf eal/riscv: support RISC-V architecture
Add all necessary elements for DPDK to compile and run EAL on SiFive
Freedom U740 SoC which is based on SiFive U74-MC (ISA: rv64imafdc)
core complex.

This includes:

- EAL library implementation for rv64imafdc ISA.
- meson build structure for 'riscv' architecture. RTE_ARCH_RISCV define
  is added for architecture identification.
- xmm_t structure operation stubs as there is no vector support in the
  U74 core.

Compilation was tested on Ubuntu and Arch Linux using riscv64 toolchain.
Clang compilation currently not supported due to issues with missing
relocation relaxation.

Two rte_rdtsc() schemes are provided: stable low-resolution using rdtime
(default) and unstable high-resolution using rdcycle. User can override
the scheme by defining RTE_RISCV_RDTSC_USE_HPM=1 during compile time of
both DPDK and the application. The reasoning for this is as follows.
The RISC-V ISA mandates that clock read by rdtime has to be of constant
period and synchronized between all hardware threads within 1 tick
(chapter 10.1 in version 20191213 of RISC-V spec).
However this clock may not be of high-enough frequency for dataplane
uses. I.e. on HiFive Unmatched (FU740) it is 1MHz.
There is a high-resolution alternative in form of rdcycle which is
clocked at the core clock frequency. The drawbacks are that it may be
disabled during sleep (WFI), its frequency might change due to DVFS and
it is core-local and therefore cannot be used as a wall-clock. It can
however be used for micro-benchmarking user applications, similarly to
Aarch64's PMCCNTR PMU counter.

The platform is currently marked as linux-only because rte_cycles
implementation uses the timebase-frequency device-tree node read through
the proc file system. Such approach was chosen because Linux kernel
depends on the presence of this device-tree node.

The i40e PMD driver is disabled on RISC-V as the rv64gc ISA has no vector
operations.

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.

To allow other projects to easily use DPDK as a subproject, add in the

drivers should not be linked in, and the internal meson dependency
objects are more complete.

To use DPDK as a subproject fallback i.e. use installed DPDK if present,
otherwise the shipped one, the following meson statement can be used:

ca04c78b62 eal: get/set thread priority per thread identifier
Add functions for setting and getting the priority of a thread.
Priorities on multiple platforms are similarly determined by a priority
value and a priority class/policy.

Currently in DPDK most threads operate at the OS-default priority level
but there are cases when increasing the priority is useful. For
example, high performance applications may require elevated priority
levels.

For these reasons, EAL will expose two priority levels which are named
suggestively "normal" and "realtime_critical" and are computed as
follows:

  On Linux, the following mapping is created:
    RTE_THREAD_PRIORITY_NORMAL corresponds to
      * policy SCHED_OTHER
      * priority value:   (sched_get_priority_min(SCHED_OTHER) +
			   sched_get_priority_max(SCHED_OTHER))/2;
    RTE_THREAD_PRIORITY_REALTIME_CRITICAL corresponds to
      * policy SCHED_RR
      * priority value: sched_get_priority_max(SCHED_RR);

  On Windows, the following mapping is created:
    RTE_THREAD_PRIORITY_NORMAL corresponds to
      * class NORMAL_PRIORITY_CLASS
      * priority THREAD_PRIORITY_NORMAL
    RTE_THREAD_PRIORITY_REALTIME_CRITICAL corresponds to
      * class REALTIME_PRIORITY_CLASS (when running with privileges)
      * class HIGH_PRIORITY_CLASS (when running without privileges)
      * priority THREAD_PRIORITY_TIME_CRITICAL

Note that on Linux the resulting priority value will be 0, in
accordance to the documentation that mention the value should be 0 for
SCHED_OTHER policy.

0bee070907 eal: add seqlock
A sequence lock (seqlock) is a synchronization primitive which allows
for data-race free, low-overhead, high-frequency reads, suitable for
data structures shared across many cores and which are updated
relatively infrequently.

A seqlock permits multiple parallel readers. A spinlock is used to
serialize writers. In cases where there is only a single writer, or
writer-writer synchronization is done by some external means, the
"raw" sequence counter type (and accompanying rte_seqcount_*()
functions) may be used instead.

To avoid resource reclamation and other issues, the data protected by
a seqlock is best off being self-contained (i.e., no pointers [except
to constant data]).

One way to think about seqlocks is that they provide means to perform
atomic operations on data objects larger than what the native atomic
machine instructions allow for.

DPDK seqlocks (and the underlying sequence counters) are not
preemption safe on the writer side. A thread preemption affects
performance, not correctness.

A seqlock contains a sequence number, which can be thought of as the
generation of the data it protects.

A reader will
  1. Load the sequence number (sn).
  2. Load, in arbitrary order, the seqlock-protected data.
  3. Load the sn again.
  4. Check if the first and second sn are equal, and even numbered.
     If they are not, discard the loaded data, and restart from 1.

The first three steps need to be ordered using suitable memory fences.

A writer will
  1. Take the spinlock, to serialize writer access.
  2. Load the sn.
  3. Store the original sn + 1 as the new sn.
  4. Perform load and stores to the seqlock-protected data.
  5. Store the original sn + 2 as the new sn.
  6. Release the spinlock.

Proper memory fencing is required to make sure the first sn store, the
data stores, and the second sn store appear to the reader in the
mentioned order.

The sn loads and stores must be atomic, but the data loads and stores
need not be.

The original seqlock design and implementation was done by Stephen
Hemminger. This is an independent implementation, using C11 atomics.
