    "content": "Bitwise operation APIs are defined and used in a lot of PMDs,\nwhich caused a huge code duplication. To reduce duplication,\nthis patch consolidates them into a common API family and use\nit for all the PMDs(we started with a few selectively).\n\nv9:\n  1. Change '*addr = (*addr) | mask' to '*addr = val | mask'\n     <Morten Brørup>.\n  2. Move 'rte_bitops.h' from 'device' section to 'basic'\n     section in 'doxy-api-index.md'<Jerin Jacob>.\nv8:\n  1. Change 'rte_pmd_bitops.h' to 'rte_bitops.h' allowing for\n     future extension into other cases other than PMD only.\n  2. Replace 'unsigned long' with 'uint32_t' to fix compling\n     errors, the reason is the fact that 32-bit and 64-bit\n     systems have different sized 'unsigned long', which caused\n     incompatibility.\n\nv7:\n  1. Change the API's head file to 'rte_pmd_bitops.h' as a common-\n     but-not-public file.\n  2. Replace C11 atomic operations with 'volatile'. As the use cases\n     are limited to PMDs, a 'volatile' is sufficient.\n\nv5,v6:\n  Trim 'unsigned long' in PMDs down to 'uint32_t', as on mainstream\n  64-bit OS, 'unsigned long' is 64-bit in size, but the 32-bit OS\n  expects 32-bit 'unsigned long' argument.\n\nv4:\n  Introduce uint32_t/uint64_t *addr when definiting bit operation\n  APIs.\n\nv3:\n  1. Change the API's head file back to rte_bitops.h, then implement\n     both 32-bit and 64-bit operations with and without C11 atomic\n     memory ordering.\n  2. Add multi-core test case for bit operations which implemented\n     with memory ordering.\n  3. Modify the doc of both APIs and test cases.\n\nv2:\n  1. Add doxygen comments for the rte bit operation API.\n  2. Add test cases for common rte bit operation API.\n  3. Change the header file to rte_io_bitops.h and the operation to\n     rte_io_set_bit() etc., as the API uses barriers inside and the\n     barriers are only needed for IO operations.\n  4. Use an well defined uint_NN_t type.\n\nJoyce Kong (6):\n  lib/eal: implement the family of common bit operation APIs\n  test/bitops: add bit operation test case\n  net/axgbe: use common rte bit operation APIs instead\n  net/bnx2x: use common rte bit operation APIs instead\n  net/qede: use common rte bit operation APIs instead\n  net/hinic: use common rte bit operation APIs instead\n\n MAINTAINERS                               |   5 +\n app/test/Makefile                         |   1 +\n app/test/autotest_data.py                 |   6 +\n app/test/meson.build                      |   2 +\n app/test/test_bitops.c                    | 137 +++++++++++\n doc/api/doxy-api-index.md                 |   7 +-\n drivers/net/axgbe/axgbe_common.h          |  29 +--\n drivers/net/axgbe/axgbe_ethdev.c          |  14 +-\n drivers/net/axgbe/axgbe_ethdev.h          |   2 +-\n drivers/net/axgbe/axgbe_mdio.c            |  15 +-\n drivers/net/bnx2x/bnx2x.c                 | 271 +++++++++++-----------\n drivers/net/bnx2x/bnx2x.h                 |  10 +-\n drivers/net/bnx2x/ecore_sp.c              |  68 +++---\n drivers/net/bnx2x/ecore_sp.h              | 106 ++++-----\n drivers/net/hinic/Makefile                |   1 +\n drivers/net/hinic/base/hinic_compat.h     |  33 +--\n drivers/net/hinic/hinic_pmd_ethdev.c      |  18 +-\n drivers/net/hinic/hinic_pmd_ethdev.h      |   2 +-\n drivers/net/hinic/meson.build             |   2 +\n drivers/net/qede/base/bcm_osal.c          |  22 +-\n drivers/net/qede/base/bcm_osal.h          |  14 +-\n drivers/net/qede/base/ecore.h             |   6 +-\n drivers/net/qede/base/ecore_cxt.c         |   6 +-\n drivers/net/qede/base/ecore_dcbx.c        |   8 +-\n drivers/net/qede/base/ecore_dev.c         |  38 +--\n drivers/net/qede/base/ecore_dev_api.h     |   2 +-\n drivers/net/qede/base/ecore_l2.c          |   6 +-\n drivers/net/qede/base/ecore_mcp.c         |   4 +-\n drivers/net/qede/base/ecore_sp_commands.c |  12 +-\n drivers/net/qede/base/ecore_spq.c         |   2 +-\n drivers/net/qede/base/ecore_spq.h         |  10 +-\n drivers/net/qede/qede_main.c              |   4 +-\n lib/librte_eal/include/meson.build        |   1 +\n lib/librte_eal/include/rte_bitops.h       | 258 ++++++++++++++++++++\n 34 files changed, 723 insertions(+), 399 deletions(-)\n create mode 100644 app/test/test_bitops.c\n create mode 100644 lib/librte_eal/include/rte_bitops.h"
