Subject: [PATCH v4 0/3] add eal functions for thread affinity and self
Date: Tue, 26 Apr 2022 00:50:39 -0700	[thread overview]
Message-ID: <1650959442-29330-1-git-send-email-roretzla@linux.microsoft.com> (raw)
In-Reply-To: <1648819793-18948-1-git-send-email-roretzla@linux.microsoft.com>

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note: previous series introducing these functions is now superseded by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
