1094dd940e cleanup compat header inclusions
With symbols going though experimental/stable stages, we accumulated
a lot of discrepancies about inclusion of the rte_compat.h header.

Some headers are including it where unneeded, while others rely on
implicit inclusion.

Fix unneeded inclusions:
$ git grep -l include..rte_compat.h |
  xargs grep -LE '__rte_(internal|experimental)' |
  xargs sed -i -e '/#include..rte_compat.h/d'

Fix missing inclusion, by inserting rte_compat.h before the first
inclusion of a DPDK header:
$ git grep -lE '__rte_(internal|experimental)' |
  xargs grep -L include..rte_compat.h |
  xargs sed -i -e \
    '0,/#include..\(rte_\|.*pmd.h.$\)/{
      s/\(#include..\(rte_\|.*pmd.h.$\)\)/#include <rte_compat.h>\n\1/
    }'

Fix missing inclusion, by inserting rte_compat.h after the last
inclusion of a non DPDK header:
$ for file in $(git grep -lE '__rte_(internal|experimental)' |
  xargs grep -L include..rte_compat.h); do
    tac $file > $file.$$
    sed -i -e \
      '0,/#include../{
        s/\(#include..*$\)/#include <rte_compat.h>\n\n\1/
      }' $file.$$
    tac $file.$$ > $file
    rm $file.$$
  done

Fix missing inclusion, by inserting rte_compat.h after the header guard:
$ git grep -lE '__rte_(internal|experimental)' |
  xargs grep -L include..rte_compat.h |
  xargs sed -i -e \
    '0,/#define/{
      s/\(#define .*$\)/\1\n\n#include <rte_compat.h>/
    }'

And finally, exclude rte_compat.h itself.
$ git checkout lib/eal/include/rte_compat.h

At the end of all this, we have a clean tree:
$ git grep -lE '__rte_(internal|experimental)' |
  xargs grep -L include..rte_compat.h

7dcd73e379 drivers/bus: set device NUMA node to unknown by default
The dev->device.numa_node field is set by each bus driver for
every device it manages to indicate on which NUMA node this device lies.

When this information is unknown, the assigned value is not consistent

when the NUMA information is unavailable. This change impacts

b29427649b dma/idxd: fix null dereference in PCI remove
The 'info' struct was being declared as a NULL pointer. If a NULL
pointer is passed to 'rte_dma_info_get', EINVAL is returned and the
struct is not populated. This subsequently causes a segfault when
dereferencing 'info'.

This patch fixes the issue by simply declaring 'info' on the stack and
passing its address to 'rte_dma_info_get'.

1a57c8d553 dma/idxd: fix partial freeing in PCI close
During PCI device close, any allocated memory needs to be free'd.
Currently, one of the free's is being called on an incorrect idxd_dmadev
struct member, namely 'batch_idx_ring'.

At device creation, memory is allocated for both 'batch_comp_ring' and
'batch_idx_ring' simultaneously. Calling free only on 'batch_idx_ring'
meant the first half of this memory was not being free'd, leading to the
memleak.

This patch fixes this memleak by calling free on 'batch_comp_ring' which
will free the memory for both rings.

When building without AVX2 support using an older compiler e.g. gcc 4.8

Generic builds using recent compilers, and all builds with a minimum

aa802b1023 dma/idxd: fix AVX2 in non-datapath functions
While all systems which will use the idxd driver for hardware will
support AVX2, if the driver is present the initialization functions e.g.
to register logs, will be called on all systems - irrespective of HW
support. This can cause issues if the system running DPDK does not have
AVX2, and the compiler has included AVX instructions in the
initialization code.

To fix this, remove AVX2 instruction set from the whole build of the
driver. Instead, we add "target(avx2)" attribute to all datapath
functions, so those - and only those functions - will having AVX2
instructions in them.

d91998ff68 dma/cnxk: fix installing internal headers
DMA module internal header files are currently being installed to the
prefix directory. This patch updates DMA meson config file to exclude
internal headers during install stage.

63990aeb08 dma/idxd: fix wrap-around in burst capacity calculation
The burst capacity calculation code assumes that the write and read
(i.e. ids_returned) values both wrap at the ring-size, but the read
value instead wraps as UINT16_MAX. Therefore, instead of just adding
ring-size to the write value in case the read is greater, we need to
just always mask the result to ensure a correct, in-range, value.

3277676319 dma/idxd: fix paths to driver sysfs directory
Recent kernel changes[1][2] mean that we cannot guarantee that the paths
in sysfs used for creating/binding a DSA or workqueue instance will be
as given in the utility script, since they are now "compatibility-mode
only". Update script to support both new paths and compatibility ones.

a2b43447e9 dma/idxd: fix burst capacity calculation
When the maximum burst size supported by HW is less than the available
ring space, incorrect capacity was returned when there was already some
jobs queued up for submission. This was because the capacity calculation
failed to subtract the number of already-enqueued jobs from the max
burst size. After subtraction is done, ensure that any negative values
(which should never occur if the user respects the reported limits), are
clamped to zero.
