Putting a '__attribute__((deprecated))' in the middle of a function
prototype does not result in the expected result with gcc (while clang
is fine with this syntax).
$ cat deprecated.c
void * __attribute__((deprecated)) incorrect() { return 0; }
__attribute__((deprecated)) void *correct(void) { return 0; }
int main(int argc, char *argv[]) { incorrect(); correct(); return 0; }
$ gcc -o deprecated.o -c deprecated.c
deprecated.c: In function ‘main’:
deprecated.c:3:1: warning: ‘correct’ is deprecated (declared at
deprecated.c:2) [-Wdeprecated-declarations]
int main(int argc, char *argv[]) { incorrect(); correct(); return 0; }
^
Move the tag on a separate line and make it the first thing of function
prototypes.
This is not perfect but we will trust reviewers to catch the other not
so easy to detect patterns.
sed -i \
-e '/^\([^#].*\)\?__rte_experimental */{' \
-e 's//\1/; s/ *$//; i\' \
-e __rte_experimental \
-e '/^$/d}' \
$(git grep -l __rte_experimental -- '*.h')
Special mention for rte_mbuf_data_addr_default():
There is either a bug or a (not yet understood) issue with gcc.
gcc won't drop this inline when unused and rte_mbuf_data_addr_default()
calls rte_mbuf_buf_addr() which itself is experimental.
This results in a build warning when not accepting experimental apis
from sources just including rte_mbuf.h.
For this specific case, we hide the call to rte_mbuf_buf_addr() under
the ALLOW_EXPERIMENTAL_API flag.

A new device feature flag, RTE_COMPDEV_FF_OP_DONE_IN_DEQUEUE
is added. A PMD should set this if the bulk of the
processing is done during the dequeue. It should leave it
cleared if the bulk of the processing is done during the
enqueue (default).
Applications can use this as a hint for tuning.

Add note on usage of op structure and when it can be
accessed and freed.

As the private_xform data can be shared by many operations
and across queue_pairs, it would be performance impacting
for PMDs to track inflights associated with one. It makes
more sense to push the responsibility to the application to
keep track of its usage and only delete the private_xform when
there are no more ops using it.

Added structure which each PMD will fill out,
providing the capabilities of each driver
(containing mainly which compression services
it supports).

Added stream data (stream) in compression operation,
which will contain the private data from each PMD
to support stateful operations.
Also, added functions to create/free this data.
