7dde9c844a drivers: omit symbol map when unneeded
In this patch, we removed the necessity of the version files and
you don't need to update these files for each release, you can just
remove them.

e9cc7c7abc common/mlx5: use build configuration dictionary
A recent commit added an explicit dependency check on common/mlx5.
For consistency, query dpdk_conf instead of the list of common drivers.

3df380f617 common/mlx5: fix disabling build
If the dependency common/mlx5 is explicitly disabled,
but net/mlx5 is not explicitly disabled,
Meson will read the full recipe of net/mlx5
and will fail when accessing a variable from common/mlx5:
drivers/net/mlx5/meson.build:76:4: ERROR: Unknown variable "mlx5_config".

The solution is to stop parsing net/mlx5 if common/mlx5 is disabled.
The deps array must be defined before stopping, in order to automatically
disable the build of net/mlx5 and print the reason.

The same protection is applied to other mlx5 drivers,
so it will allow using the variable mlx5_config in future.

 - Return error and report for unknown keys.

which keys it has used, then common driver receives the updated

71304b5c7b common/mlx5: fix redundant field in MR control structure
Inside the MR control structure there is a pointer to the common device.
This pointer enables access to the global cache as well as hardware
objects that may be required in case a new MR needs to be created.

The purpose of adding this pointer into the MR control structure was to
avoid its transfer as a parameter to all the functions of searching MR
in the caches.
However, adding it to this structure increased the Rx and Tx data-path
structures, all the fields that followed it were slightly moved away
which caused to a reduction in performance.

This patch removes the pointer from the structure. It can be accessed
through the "dev_gen_ptr" existing field using the "container_of"
operator.

5dfa003db5 common/mlx5: fix post doorbell barrier
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 an 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 UAR creation function maps a doorbell in one of the above ways
according to the system. In run time, it always adds an explicit memory
barrier after writing to.
In cases where the doorbell was mapped as non-cached memory, the
explicit memory barrier is unnecessary and may impair performance.

The commit [1] solved this problem for a Tx queue. In run time, it
checks the mapping type and provides the memory barrier after writing to
a Tx doorbell register if it is needed. The mapping type is extracted
directly from the uar_mmap_offset field in the queue properties.

This patch shares this code between the drivers and extends the above
solution for each of them.

b4371d3d56 common/mlx5: fix doorbell mapping configuration
UAR mapping type can be affected by the devarg tx_db_nc, which can cause
setting the environment variable MLX5_SHUT_UP_BF.
So, the MLX5_SHUT_UP_BF value and the UAR mapping parameter affect the
UAR cache mode.

Wrongly, the devarg was considered for the MLX5_SHUT_UP_BF but not for
the UAR mapping parameter in all the drivers except the net.

Take the tx_db_nc devarg into account for all the drivers.

204891763c common/mlx5: make multi-process MR management port-agnostic
In the multi-process mechanism, there are things that the secondary
process does not perform itself but asks the primary process to perform
for it.
There is a special API for communication between the processes that
receives parameters necessary for the specific action required as well
as a special structure called mp_id that contains the port number of the
processes through which the initial process finds the relevant ETH
device for the processes.

One of the operations performed through this mechanism is the creation
of a memory region, where the secondary process sends the virtual
address as a parameter and the mp_id structure with the port number
inside it.
However, once the memory area management is shared between the drivers
and either port number or ETH device is no longer relevant to them, it
seems unnecessary to continue communicating between the processes
through the mp_id variable.

In this patch we will remove the use of the above structure for all MR
management, and add to the specific parameter of operations a pointer to
the common device that contains everything needed to create/register MR.

334ed198ab common/mlx5: remove redundant parameter in MR search
Memory region management has recently been shared between drivers,
including the search for caches in the data plane.
The initial search in the local linear cache of the queue, usually
yields a result and one should not continue searching in the next level
caches.

The function that searches in the local cache gets the pointer to a
device as a parameter, that is not necessary for its operation
but for subsequent searches (which, as mentioned, usually do not
happen).
Transferring the device to a function and maintaining it, takes some
time and causes some impact on performance.

Add the pointer to the device as a field of the mr_ctrl structure. The
field will be updated during control path and will be used only when
needed in the search.

fdab8f2e17 version: 21.11-rc0
Start a new release cycle with empty release notes.

The ABI version becomes 22.0.
The map files are updated to the new ABI major number (22).
The ABI exceptions are dropped and CI ABI checks are disabled because
compatibility is not preserved.

34c84ebbbc regex/mlx5: fix redundancy in device removal
In the removal function, PMD releases all driver resources and
cancels the regexdev registry.

However, regexdev registration is accidentally canceled twice.
Remove one of them.

a1fcde8c80 regex/mlx5: fix leak on device removal
In the removal function, PMD releases all driver resources allocated
in the probe function.

The MR btree memory is allocated in the probe function, but it is not
freed in remove function what caused a memory leak.

Release it.

29ca3215f3 regex/mlx5: fix memory region unregistration
The issue can cause illegal physical address access while a huge-page A
is released and huge-page B is allocated on the same virtual address.
The old MR can be matched using the virtual address of huge-page B but
the HW will access the physical address of huge-page A which is no more
part of the DPDK process.

Register a driver callback for memory event in order to free out all the
MRs of memory that is going to be freed from the DPDK process.

423719a367 regex/mlx5: fix size of setup constants
The constant representing the size of the metadata is defined as an
unsigned int variable with 32-bit.
Similarly the constant representing the maximal output is also defined
as an unsigned int variable with 32-bit.

There is potentially overflowing expression when those constants are
evaluated using 32-bit arithmetic, and then used in a context that
expects an expression of type size_t that might be 64-bit.

Change the size of the above constants to size_t.
