4 years agobuild: skip config of explicitly disabled drivers

build: skip config of explicitly disabled drivers

Even when a PMD was disabled with meson's disable_drivers option
its config file was still being parsed. Some of the PMD configs
attempt to find a library they depend on and parse its header files
with certain assumptions. If the library is found, but it's simply
too old to contain the necessary header files, the meson build
fails and it can only be fixed by either updating that library, or
expanding the meson script for the faulty PMD.

While the latter should be still done for the sake of DPDK quality,
an intermediate solution would be to skip building the faulty PMD
- there's a chance we don't need it. That's what this patch allows.

4 years agometer: provide experimental alias for matured API

meter: provide experimental alias for matured API

On v20.02 some meter APIs have been matured and symbols moved from
EXPERIMENTAL to DPDK_20.0.1 block.

This can break the applications that were using these mentioned APIs on
v19.11. Although there is no modification on the APIs and the action is
positive and matures the APIs, the affect can be negative to
applications.

This patch provides aliasing by duplicating the existing and versioned
symbols as experimental.

Since symbols moved from DPDK_20.0.1 to DPDK_21 block in the v20.05, the
aliasing done between EXPERIMENTAL and DPDK_21.

With DPDK_21 ABI (DPDK v20.11) all aliasing will be removed and only
stable version of the APIs will remain.

fields set with the uninitialized value will be overwritten in the
following code part and the macros. All the fields will be used as

net/mlx5: fix flow counter container resize

The design of counter container resize used double buffer algorithm in
order to synchronize between the query thread to the control thread.
When the control thread detected resize need, it created new bigger

EAGAIN to the flow creation API used a COUNT action.

The rte_flow API doesn't allow unblocked commands and doesn't expect to
get EAGAIN error type.

So, when a lot of flows were created between 2 different periodic
queries, 2 different resizes might try to be created and caused EAGAIN
error.
This behavior may blame flow creations.

4 years agocompat: provide experimental alias for matured ABI
Ferruh Yigit [Fri, 15 May 2020 15:01:53 +0000 (16:01 +0100)]
compat: provide experimental alias for matured ABI

On v20.02 some APIs matured and symbols moved from EXPERIMENTAL to
DPDK_20.0.1 block.

This had the affect of breaking the applications that were using these
APIs on v19.11. Although there is no modification of the APIs and the
action is positive and matures the APIs, the affect can be negative to
applications.

When a maintainer is promoting an API to become part of the next major
ABI version by removing the experimental tag. The maintainer may
choose to offer an alias to the experimental tag, to prevent these
breakages in future.

The following changes are made to enabling aliasing:

Updated to the ABI policy and ABI versioning documents.

Created VERSION_SYMBOL_EXPERIMENTAL helper macro.

Updated the 'check-symbols.sh' tool, which was complaining that the
symbol is in EXPERIMENTAL tag in .map file but it is not in the
.experimental section (__rte_experimental tag is missing).
Updated tool in a way it won't complain if the symbol in the
EXPERIMENTAL tag duplicated in some other block in .map file (versioned)

doc: fix default symbol binding in ABI guide

The document abi_versioning.rst incorrectly instructs the developer to
add BIND_DEFAULT_SYMBOL to the public header, not the source file. This
commit fixes the issue and adds some clarifications.

The commit also clarifies the use of use_function_versioning in the
meson/ninja build system, and does some minor re-organization of the
document.
