bab51810b6 compress/mlx5: refactor HW queue object
The mlx5 PMD for compress class uses an MMO WQE operated by the GGA
engine in BF devices.
Currently, all the MMO WQEs are managed by the SQ object.
Starting from BF3, the queue of the MMO WQEs should be connected to the
GGA engine using a new configuration, MMO, that will be supported only
in the QP object.
The FW introduced new capabilities to define whether the MMO
configuration should be configured for the GGA queue.
Replace all the GGA queue objects to QP, set MMO configuration according
to the new FW capabilities.

12b253ee87 compress/mlx5: fix leak on QP setup failure
The QP setup function allocates buffer for its
opaque MR and register it into MR structure.

After buffer allocation and before MR registration,
it tries allocate MR Btree.
When the MR Btree allocation fails, the buffer was
not freed what caused a memory leak.

Allocate the MR Btree before buffer alloction.

The ABI exceptions are dropped and CI ABI checks are disabled because

237aad8824 compress/mlx5: fix compression level translation
Compression Level is interpreted by each PMD differently.
However, lower numbers give faster compression
at the expense of compression ratio, while higher numbers
may give better compression ratios but are likely slower.
The level affects the block size, which affects performance,
the bigger the block, the faster the compression is.

The problem was that higher levels caused bigger blocks:
  size = min_block_size - 1 + level.

the solution is to reverse the above:
  size = max_block_size + 1 - level.

c87bc83a33 compress/mlx5: fix overflow in queue size
The mlx5_compress_qp_setup function makes shifting to the numeric
constant 1, then sends it as a parameter to rte_calloc function.

The rte_calloc function expects to get size_t (might be 64 bit) and
instead gets a 32-bit variable, because the numeric constant size is a
32-bit.
In case the shift is greater than 32 bit and it 64-system, the variable
will lose its value even though the function can get 64-bit argument.

Change the size of the numeric constant 1 to size_t.

8c09010614 compress/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.

eeded2044a log: register with standardized names
Let's try to enforce the convention where most drivers use a pmd. logtype
with their class reflected in it, and libraries use a lib. logtype.

Introduce two new macros:
- RTE_LOG_REGISTER_DEFAULT can be used when a single logtype is
  used in a component. It is associated to the default name provided
  by the build system,
- RTE_LOG_REGISTER_SUFFIX can be used when multiple logtypes are used,
  and then the passed name is appended to the default name,

RTE_LOG_REGISTER is left untouched for existing external users
and for components that do not comply with the convention.

There is a new Meson variable log_prefix to adapt the default name
for baseband (pmd.bb.), bus (no pmd.) and mempool (no pmd.) classes.

Note: achieved with below commands + reverted change on net/bonding +
edits on crypto/virtio, compress/mlx5, regex/mlx5

$ git grep -l RTE_LOG_REGISTER drivers/ |

    pattern=${file##drivers/};

returned by the get_device_list glue function and returns the ib device
matching the provided address.

Since this function is in use by several drivers, in this patch we

10787aa2b9 compress/mlx5: support timestamp format
This patch adds support for the timestamp format settings for
the receive and send queues. If the firmware version x.30.1000
or above is installed and the NIC timestamps are configured
with the real-time format, the default zero values for newly
added fields cause the queue creation to fail.

The patch queries the timestamp formats supported by the hardware
and sets the configuration values in queue context accordingly.

37862dafcb compress/mlx5: support 32-bit systems
In order to support 32-bit systems, the 8B doorbell write should be
done by 2 4B stores.

The order between the store is important, that's why memory barrier
should be used between them.

The doorbell address is shared between all the queues, that's why a lock
should wrap the 2 stores.

0165bccdb4 compress/mlx5: add memory region management
Mellanox user space drivers don't deal with physical addresses, that's
why any mbuf virtual address moved directly to the HW descriptor(WQE).

The mapping between the virtual address to the physical address is saved
in MR configured by the kernel to the HW.

Each MR has a key that should also be moved to the WQE by the SW.

When the SW see address which is not mapped, it extends the address
range and creates a MR using a system call.

Add memory region cache management:
	- 2 level cache per queue-pair - no locks.
	- 1 shared cache between all the queues using a lock.

Using this way, the MR key search per data-path address is optimized.

832a4cf1d1 compress/mlx5: introduce PMD
Add a new compress PMD for Mellanox devices.

The MLX5 compress driver library provides support for Mellanox
BlueField 2 families of 25/50/100/200 Gb/s adapters.

GGAs (Generic Global Accelerators) are offload engines that can be used
to do memory to memory tasks on data.
These engines are part of the ARM complex of the BlueField 2 chip, and
as such they do not use NIC related resources (e.g. RX/TX bandwidth).
They do share the same PCI and memory bandwidth.

So, using the BlueField 2 device, the compress class operations can be
run in parallel to the net, vdpa, and regex class operations.

This driver is depending on rdma-core like the other mlx5 PMDs, also it
is going to use mlx5 DevX to create HW objects directly by the FW.

Add the probing functions, PCI bus connectivity, HW capabilities checks
and some basic objects preparations.
