This is a wrapper to Linux kernel get_maintainer.pl file and only
supports parsing MAINTAINERS file (no git fallback etc..)
Requires DPDK_GETMAINTAINER_PATH devel config option set, please check
devtools/load-devel-config.
DPDK_GETMAINTAINER_PATH should be full path to the get_maintainer.pl
script, like:
DPDK_GETMAINTAINER_PATH=~/linux/scripts/get_maintainer.pl
Can be used individually:
./devtools/get-maintainer.sh <my.patch>
Or via git send-email, to add maintainers automatically:
git send-email --to-cmd ./devtools/get-maintainer.sh \
--cc dev@dpdk.org HEAD -4
Currently there is an ugly workaround to be able to use Linux script out
of the kernel tree, later better method can replace it.

- return success even it abi is incompatible

The script git-log-fixes.sh (used in check-git-log.sh) looks
for git tags to find the version where a bug is introduced.
In DPDK 17.08, the script has been fixed to ignore tags from
non current branch.
It was using the option --merged which was introduced in git 2.7.0.
As git 2.7.0 is not so old, a fallback is provided for some years.
The fallback is replacing the tag --merged option by a branch filter.
If the tag is found in the branch, the branch name is replaced
by the tag.
This script could be improved to allow using another reference branch,
instead of hard coding HEAD branch (the current one).

Currently EAL allocates hugepages one by one not paying attention
from which NUMA node allocation was done.
Such behaviour leads to allocation failure if number of available
hugepages for application limited by cgroups or hugetlbfs and
memory requested not only from the first socket.
Example:
# 90 x 1GB hugepages availavle in a system
cgcreate -g hugetlb:/test
# Limit to 32GB of hugepages
cgset -r hugetlb.1GB.limit_in_bytes=34359738368 test
# Request 4GB from each of 2 sockets
cgexec -g hugetlb:test testpmd --socket-mem=4096,4096 ...
EAL: SIGBUS: Cannot mmap more hugepages of size 1024 MB
EAL: 32 not 90 hugepages of size 1024 MB allocated
EAL: Not enough memory available on socket 1!
Requested: 4096MB, available: 0MB
PANIC in rte_eal_init():
Cannot init memory
This happens beacause all allocated pages are
on socket 0.
Fix this issue by setting mempolicy MPOL_PREFERRED for each hugepage
to one of requested nodes using following schema:
1) Allocate essential hugepages:
1.1) Allocate as many hugepages from numa N to
only fit requested memory for this numa.
1.2) repeat 1.1 for all numa nodes.
2) Try to map all remaining free hugepages in a round-robin
fashion.
3) Sort pages and choose the most suitable.
In this case all essential memory will be allocated and all remaining
pages will be fairly distributed between all requested nodes.
New config option RTE_EAL_NUMA_AWARE_HUGEPAGES introduced and
enabled by default for linuxapp except armv7 and dpaa2.
Enabling of this option adds libnuma as a dependency for EAL.

Before this patch, the management of dependencies between directories
had several issues:
- the generation of .depdirs, done at configuration is slow: it can take
more than one minute on some slow targets (usually ~10s on a standard
PC without -j).
- for instance, it is possible to express a dependency like:
- app/foo depends on lib/librte_foo
- and lib/librte_foo depends on app/bar
But this won't work because the directories are traversed with a
depth-first algorithm, so we have to choose between doing 'app' before
or after 'lib'.
- the script depdirs-rule.sh is too complex.
- we cannot use "make -d" for debug, because the output of make is used for
the generation of .depdirs.
This patch moves the DEPDIRS-* variables in the upper Makefile, making
the dependencies much easier to calculate. A DEPDIRS variable is still
used to process library dependencies in LDLIBS.
After this commit, "make config" is almost immediate.

The checkpatch.pl tool is flagging warnings on long debug log strings.
Since splitting these strings makes it difficult to search for logs it is
preferred to allow these as exceptions to the long line rule. The addition
of the LONG_LINE_STRINGS to the list of exceptions will allow lines that
end with a string to exceed the maximum line length, but lines that end
with variables or other constructs will still be flagged as errors. Also,
lines that make use of PRIx64 with string concatenation will still be
flagged if the beginning of the last string fragment begins after the 80
character threshold.

When config creation done under a single make target, using a for loop,
make has no control on the action, and it needs to run as implemented in
the rule. But if for loop converted into multiple targets, make can
detect independent targets and run them parallel based on -j parameter.

This patch introduces crypto poll mode driver
using ARMv8 cryptographic extensions.
CPU compatibility with this driver is detected in
run-time and virtual crypto device will not be
created if CPU doesn't provide:
AES, SHA1, SHA2 and NEON.
This PMD is optimized to provide performance boost
for chained crypto operations processing,
such as encryption + HMAC generation,
decryption + HMAC validation. In particular,
cipher only or hash only operations are
not provided.
The driver currently supports AES-128-CBC
in combination with: SHA256 HMAC and SHA1 HMAC
and relies on the external armv8_crypto library:
https://github.com/caviumnetworks/armv8_crypto
Build ARMv8 crypto PMD if compiling for ARM64
and CONFIG_RTE_LIBRTE_PMD_ARMV8_CRYPTO option
is enable in the configuration file.
ARMV8_CRYPTO_LIB_PATH environment variable will
point to the appropriate library directory.
