a04322f616 bus: hide bus object
Make rte_bus opaque for non internal users.
This will make extending this object possible without breaking the ABI.

Introduce a new driver header and move rte_bus definition and helpers.
Update drivers and library to use the internal header.

Some applications may have been dereferencing rte_bus objects, mark
this object's accessors as stable.

925c074e37 bus/ifpga: make driver-only headers private
The ifpga bus interface is for drivers only.
Mark as internal and move the header in the driver headers list.

While at it, cleanup the code:
- remove unneeded list head structure type,
- reorder the definitions and macro manipulating the bus singleton object,
- remove inclusion of rte_bus.h and fix the code that relied on implicit
  inclusion,

9c89c333bc bus/ifpga: cleanup exported symbols
Remove unused symbols (exposed only in an internal header which

Remove rte_ prefix and inline the rest to avoid having to expose them as

f1f6ebc0ea eal: remove sys/queue.h from public headers
Currently there are some public headers that include 'sys/queue.h', which
is not POSIX, but usually provided by the Linux/BSD system library.
(Not in POSIX.1, POSIX.1-2001, or POSIX.1-2008. Present on the BSDs.)
The file is missing on Windows. During the Windows build, DPDK uses a
bundled copy, so building a DPDK library works fine.  But when OVS or other
applications use DPDK as a library, because some DPDK public headers
include 'sys/queue.h', on Windows, it triggers an error due to no such
file.

One solution is to install the 'lib/eal/windows/include/sys/queue.h' into
Windows environment, such as [1]. However, this means DPDK exports the
functionalities of 'sys/queue.h' into the environment, which might cause
symbols, macros, headers clashing with other applications.

The patch fixes it by removing the "#include <sys/queue.h>" from
DPDK public headers, so programs including DPDK headers don't depend
on the system to provide 'sys/queue.h'. When these public headers use
macros such as TAILQ_xxx, we replace it by the ones with RTE_ prefix.
For Windows, we copy the definitions from <sys/queue.h> to rte_os.h
in Windows EAL. Note that these RTE_ macros are compatible with
<sys/queue.h>, both at the level of API (to use with <sys/queue.h>
macros in C files) and ABI (to avoid breaking it).

Additionally, the TAILQ_FOREACH_SAFE is not part of <sys/queue.h>,
the patch replaces it with RTE_TAILQ_FOREACH_SAFE.

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

10b71caecb rawdev: add private data size to info query
Currently with the rawdev API there is no way to check that the structure
passed in via the dev_private pointer in the dev_info structure is of the
correct type - it's just checked that it is non-NULL. Adding in the length
of the expected structure provides a measure of typechecking, and can also
be used for ABI compatibility in future, since ABI changes involving
structs almost always involve a change in size.

(LIBABIVER := numbers, optionally preceded by a comment and optionally

fb87e55aba bus/ifpga: fix AFU probe failure handler
In the original code, when an AFU device probe a driver,
if the first driver in the driver list does not support
this device or some error happens, bus probe returns an error.

With this patch, a device will try to match driver in the driver
list one by one until an appropriate driver is found.

If some error happens, the error is returned. If the current driver
does not support the device, just try the next driver in the list.

If all the drivers in the list are tried and no driver matches,
0 is returned. Otherwise, the error code is returned.

e9d159c3d5 eal: allow probing a device again
In the devargs syntax for device representors, it is possible to add
several devices at once: -w dbdf,representor=[0-3]
It will become a more frequent case when introducing wildcards
and ranges in the new devargs syntax.

If a devargs string is provided for probing, and updated with a bigger
range for a new probing, then we do not want it to fail because
part of this range was already probed previously.
There can be new ports to create from an existing rte_device.

That's why the check for an already probed device
is moved as bus responsibility.
In the case of vdev, a global check is kept in insert_vdev(),
assuming that a vdev will always have only one port.
In the case of ifpga and vmbus, already probed devices are checked.
In the case of NXP buses, the probing is done only once (no hotplug),
though a check is added at bus level for consistency.
In the case of PCI, a driver flag is added to allow PMD probing again.
Only the PMD knows the ports attached to one rte_device.

As another consequence of being able to probe in several steps,
the field rte_device.devargs must not be considered as a full
representation of the rte_device, but only the latest probing args.
Anyway, the field rte_device.devargs is used only for probing.

391797f042 drivers/bus: move driver assignment to end of probing
The PCI mapping requires to know the PCI driver to use,
even before the probing is done. That's why the PCI driver is
referenced early inside the PCI device structure. See
commit 1d20a073fa ("bus/pci: reference driver structure before mapping")

However the rte_driver does not need to be referenced in rte_device
before the device probing is done.
By moving back this assignment at the end of the device probing,
it becomes possible to make clear the status of a rte_device.

6844d146ff eal: add bus pointer in device structure
When a device is added with a devargs (hotplug or whitelist),
the bus pointer can be retrieved via its devargs.
But there is no such devargs.bus in case of standard scan.

A pointer to the rte_bus handle is added to rte_device.
When a device is allocated (during a scan),
the pointer to its bus is assigned.

It will make possible to remove a rte_device,
using the function pointer from its bus.

The function rte_bus_find_by_device() becomes useless,
and may be removed later.

05fa3d4a65 bus/ifpga: add Intel FPGA bus library
Defined FPGA-BUS for Acceleration Drivers of AFUs

1. FPGA PCI Scan (1st Scan) follows DPDK UIO/VFIO PCI Scan Process,
probe Intel FPGA Rawdev Driver, it will be covered in following patches.

2. AFU Scan(2nd Scan) bind DPDK driver to FPGA Partial-Bitstream.
This scan is trigged by hotplug of IFPGA Rawdev probe, in this scan
the AFUs will be created and their drivers are also probed.

This patch will introduce rte_afu_device which describe the AFU device
listed in the FPGA-BUS.
