The rdma core library can map doorbell register in two ways,
depending on the environment variable "MLX5_SHUT_UP_BF":
- as regular cached memory, the variable is either missing or
set to zero. This type of mapping may cause the significant
doorbell register writing latency and requires explicit
memory write barrier to mitigate this issue and prevent
write combining.
- as non-cached memory, the variable is present and set to
not "0" value. This type of mapping may cause performance
impact under heavy loading conditions but the explicit write
memory barrier is not required and it may improve core
performance.
The new devarg is introduced "tx_db_nc", if this parameter is
set to zero, the doorbell register is forced to be mapped to
cached memory and requires explicit memory barrier after
writing to. If "tx_db_nc" is set to non-zero value the doorbell
will be mapped as non-cached memory, not requiring the memory
barrier. If "tx_db_nc" is missing the behaviour will be defined
by presence of "MLX5_SHUT_UP_BF" in environment. If variable
is missed the default value zero will be set for ARM64 hosts
and one for others.
In run time the code checks the mapping type and provides the
memory barrier after writing to tx doorbell register if it is
needed. The mapping type is extracted directly from the
uar_mmap_offset field in the queue properties.

The PMD parameter dv_xmeta_en is added to control extensive
metadata support. A nonzero value enables extensive flow
metadata support if device is capable and driver supports it.
This can enable extensive support of MARK and META item of
rte_flow. The newly introduced SET_TAG and SET_META actions
do not depend on dv_xmeta_en parameter, because there is
no compatibility issue for new entities. The dv_xmeta_en is
disabled by default.
There are some possible configurations, depending on parameter
value:
- 0, this is default value, defines the legacy mode, the MARK
and META related actions and items operate only within NIC Tx
and NIC Rx steering domains, no MARK and META information
crosses the domain boundaries. The MARK item is 24 bits wide,
the META item is 32 bits wide.
- 1, this engages extensive metadata mode, the MARK and META
related actions and items operate within all supported steering
domains, including FDB, MARK and META information may cross
the domain boundaries. The ``MARK`` item is 24 bits wide, the
META item width depends on kernel and firmware configurations
and might be 0, 16 or 32 bits. Within NIC Tx domain META data
width is 32 bits for compatibility, the actual width of data
transferred to the FDB domain depends on kernel configuration
and may be vary. The actual supported width can be retrieved
in runtime by series of rte_flow_validate() trials.
- 2, this engages extensive metadata mode, the MARK and META
related actions and items operate within all supported steering
domains, including FDB, MARK and META information may cross
the domain boundaries. The META item is 32 bits wide, the MARK
item width depends on kernel and firmware configurations and
might be 0, 16 or 24 bits. The actual supported width can be

The dynamic mbuf fields were introduced by [1]. The egress metadata is
good candidate to be moved from statically allocated field tx_metadata to
dynamic one. Because mbufs are used in half-duplex fashion only, it is
safe to share this dynamic field with ingress metadata.
The shared dynamic field contains either egress (if application going to
transmit mbuf with tx_burst) or ingress (if mbuf is received with rx_burst)
metadata and can be accessed by RTE_FLOW_DYNF_METADATA() macro or with
rte_flow_dynf_metadata_set() and rte_flow_dynf_metadata_get() helper
routines. PKT_TX_DYNF_METADATA/PKT_RX_DYNF_METADATA flag will be set
along with the data.
The mbuf dynamic field must be registered by calling
rte_flow_dynf_metadata_register() prior accessing the data.
The availability of dynamic mbuf metadata field can be checked with
rte_flow_dynf_metadata_avail() routine.
DEV_TX_OFFLOAD_MATCH_METADATA offload and configuration flag is removed.
The metadata support in PMDs is engaged on dynamic field registration.
Metadata feature is getting complex. We might have some set of actions
and items that might be supported by PMDs in multiple combinations,

Currently, metadata can be set on egress path via mbuf tx_metadata field
with PKT_TX_METADATA flag and RTE_FLOW_ITEM_TYPE_META matches metadata.
This patch extends the metadata feature usability.
1) RTE_FLOW_ACTION_TYPE_SET_META
When supporting multiple tables, Tx metadata can also be set by a rule and
matched by another rule. This new action allows metadata to be set as a
result of flow match.
2) Metadata on ingress
There's also need to support metadata on ingress. Metadata can be set by
SET_META action and matched by META item like Tx. The final value set by
the action will be delivered to application via metadata dynamic field of
mbuf which can be accessed by RTE_FLOW_DYNF_METADATA() macro or with
rte_flow_dynf_metadata_set() and rte_flow_dynf_metadata_get() helper
routines. PKT_RX_DYNF_METADATA flag will be set along with the data.
The mbuf dynamic field must be registered by calling
rte_flow_dynf_metadata_register() prior to use SET_META action.
The availability of dynamic mbuf metadata field can be checked
with rte_flow_dynf_metadata_avail() routine.
If application is going to engage the metadata feature it registers
the metadata dynamic fields, then PMD checks the metadata field
availability and handles the appropriate fields in datapath.
For loopback/hairpin packet, metadata set on Rx/Tx may or may not be
propagated to the other path depending on hardware capability.
MARK and METADATA look similar and might operate in similar way,
but not interacting.
Initially, there were proposed two metadata related actions:
- RTE_FLOW_ACTION_TYPE_FLAG
- RTE_FLOW_ACTION_TYPE_MARK
These actions set the special flag in the packet metadata, MARK action
stores some specified value in the metadata storage, and, on the packet
receiving PMD puts the flag and value to the mbuf and applications can
see the packet was threated inside flow engine according to the appropriate
RTE flow(s). MARK and FLAG are like some kind of gateway to transfer some
per-packet information from the flow engine to the application via
receiving datapath. Also, there is the item of type RTE_FLOW_ITEM_TYPE_MARK
provided. It allows us to extend the flow match pattern with the capability
to match the metadata values set by MARK/FLAG actions on other flows.
From the datapath point of view, the MARK and FLAG are related to the
receiving side only. It would useful to have the same gateway on the
transmitting side and there was the feature of type RTE_FLOW_ITEM_TYPE_META
was proposed. The application can fill the field in mbuf and this value
will be transferred to some field in the packet metadata inside the flow
engine. It did not matter whether these metadata fields are shared because
of MARK and META items belonged to different domains (receiving and
transmitting) and could be vendor-specific.
So far, so good, DPDK proposes some entities to control metadata inside
the flow engine and gateways to exchange these values on a per-packet basis
via datapaths.
As we can see, the MARK and META means are not symmetric, there is absent
action which would allow us to set META value on the transmitting path.
So, the action of type:
- RTE_FLOW_ACTION_TYPE_SET_META was proposed.
The next, applications raise the new requirements for packet metadata.
The flow ngines are getting more complex, internal switches are introduced,
multiple ports might be supported within the same flow engine namespace.
From the DPDK points of view, it means the packets might be sent on one
eth_dev port and received on the other one, and the packet path inside
the flow engine entirely belongs to the same hardware device. The simplest
example is SR-IOV with PF, VFs and the representors. And there is a
brilliant opportunity to provide some out-of-band channel to transfer
some extra data from one port to another one, besides the packet data
itself. And applications would like to use this opportunity.
It is supposed for application to use trials (with rte_flow_validate)
to detect which metadata features (FLAG, MARK, META) actually supported
by PMD and underlying hardware. It might depend on PMD configuration,
system software, hardware settings, etc., and should be detected
in run time.

A tag is a transient data which can be used during flow match. This can be
used to store match result from a previous table so that the same pattern
need not be matched again on the next table. Even if outer header is
decapsulated on the previous match, the match result can be kept.
Some device expose internal registers of its flow processing pipeline and
those registers are quite useful for stateful connection tracking as it
keeps status of flow matching. Multiple tags are supported by specifying
index.
Example testpmd commands are:
flow create 0 ingress pattern ... / end
actions set_tag index 2 value 0xaa00bb mask 0xffff00ff /

everything twice, we just flag to the build system which libraries need
that handling, by setting use_function_versioning in the meson.build files.
To ensure we don't get silent errors at build time due to this meson flag
being missed, we add an explicit error to the function versioning header
file if a known C macro is not defined. Since "make" builds always only
build one of shared or static libraries, this define can be always set, and
so is added to the global CFLAGS. For meson, the build flag - and therefore
the C define - is set for the three libraries that need the function
versioning: "distributor", "lpm" and "timer".

The compat.h header file provided macros for two purposes:
1. it provided the macros for marking functions as rte_experimental
2. it provided the macros for doing function versioning
Although these were in the same file, #1 is something that is for use by
public header files, which #2 is for internal use only. Therefore, we can
split these into two headers, keeping #1 in rte_compat.h and #2 in a new
file rte_function_versioning.h. For "make" builds, since internal objects
pick up the headers from the "include/" folder, we need to add the new
header to the installation list, but for "meson" builds it does not need to
be installed as it's not for public use.
The rework also serves to allow the use of the function versioning macros
to files that actually need them, so the use of experimental functions does
not need including of the versioning code.

In some scenarios, the raw_encap/raw_decap actions could be multiple in
one single flow (e,g. hirepin flow):
... actions raw_decap / raw_encap / raw_decap / raw_encap / ...
This requires the testpmd supports multiple raw_encap/raw_decap data
settings as well.
With the multiple raw_encap/raw_decap settings, the testpmd commands –
set raw_encap / set raw_decap will become:
set raw_encap <index> <item pattern>
set raw_decap <index> <item pattern>
And the actions – raw_encap/raw_decap also could optionally choose which
global raw_encap/raw_decap confs to be used by index:
... actions raw_decap index 1 / raw_encap index 2 / ...
If there is no `index` specified, the default index is 0:
set raw_encap <item pattern>
... actions raw_decap / raw_encap / ...
which will use raw_encap index 0.
In addition to the set raw_encap/raw_decap commands,
show <raw_encap/raw_decap> <index>
show <raw_encap/raw_decap> all
are also introduced into in order to check which index is set and to
what.

Many features require to store data inside the mbuf. As the room in mbuf
structure is limited, it is not possible to have a field for each
feature. Also, changing fields in the mbuf structure can break the API
or ABI.
This commit addresses these issues, by enabling the dynamic registration
of fields or flags:
- a dynamic field is a named area in the rte_mbuf structure, with a
given size (>= 1 byte) and alignment constraint.
- a dynamic flag is a named bit in the rte_mbuf structure.
The typical use case is a PMD that registers space for an offload
feature, when the application requests to enable this feature. As
the space in mbuf is limited, the space should only be reserved if it
is going to be used (i.e when the application explicitly asks for it).
The registration can be done at any moment, but it is not possible
to unregister fields or flags.

This patch enables the unaligned chunks feature for AF_XDP which allows
chunks to be placed at arbitrary places in the umem, as opposed to them
being required to be aligned to 2k. This allows for DPDK application
mempools to be mapped directly into the umem and in turn enable zero copy
transfer between umem and the PMD.
This patch replaces the zero copy via external mbuf mechanism introduced
in commit e9ff8bb719 ("net/af_xdp: enable zero copy by external mbuf").
The pmd_zero copy vdev argument is also removed as now the PMD will
auto-detect presence of the unaligned chunks feature and enable it if so
and otherwise fall back to copy mode if not detected.

The rte_vhost_dequeue_burst supports two ways of dequeuing data.
If the data fits into a buffer, then all data is copied and a
single linear buffer is returned. Otherwise it allocates
additional mbufs and chains them together to return a multiple
segments mbuf.
While that covers most use cases, it forces applications that
need to work with larger data sizes to support multiple segments
mbufs. The non-linear characteristic brings complexity and
performance implications to the application.
To resolve the issue, add support to attach external buffer
to a pktmbuf and let the host provide during registration if
attaching an external buffer to pktmbuf is supported and if
only linear buffer are supported.
