Errors-To: dev-bounces@dpdk.org
this series provides basic dependencies for additional eal thread api
additions. series includes
* basic platform error number conversion.
* function to get current thread identifier.
* functions to get and set affinity with platform agnostic thread
identifier.
* minimal unit test of get and set affinity demonstrating usage.
note: previous series introducing these functions is now superseded by
this series.
http://patches.dpdk.org/project/dpdk/list/?series=20472&state=*
v4:
* combine patch eal/windows: translate Windows errors to errno-style
errors into eal: implement functions for get/set thread affinity
patch. the former introduced static functions that were not used
without eal: implement functions for get/set thread affinity which
would cause a build break when applied standalone.
* remove struct tag from rte_thread_t struct typedef.
* remove rte_ prefix from rte_convert_cpuset_to_affinity static
function.
v3:
* fix memory leak on eal_create_cpu_map error paths.
v2:
* add missing boilerplate comments warning of experimental api
for rte_thread_{set,get}_affinity_by_id().
* don't break literal format string to log_early to improve
searchability.
* fix multi-line comment style to match file.
* return ENOTSUP instead of EINVAL from rte_convert_cpuset_to_affinity()
if cpus in set are not part of the same processor group and note
limitation in commit message.
* expand series to include rte_thread_self().
* modify unit test to remove use of implementation detail and
get thread identifier use added rte_thread_self().
* move literal value to rhs when using memcmp in RTE_TEST_ASSERT
Tyler Retzlaff (3):
eal: add basic thread ID and current thread identifier API
eal: implement functions for get/set thread affinity
test/threads: add unit test for thread API
