The\nexisting __rte_packed macro is then used to restore the pack value\nprior to the push.\n\nInstead of providing macros exclusively for MSVC and for GCC the\nexisting macro is deliberately utilized to trigger a warning if no\nexisting packing has been pushed allowing easy identification of\nlocations where the __rte_msvc_pack is missing.\n\nI've decided to only add the macro to packed structs that are built\nfor Windows. It seems there is little value in adding the macro tree\nwide and if new code arrives that is built on Windows the __rte_packed\nwill flag where the preamble macro is required.\n\nIf as a part of review maintainers identify structs they believe\ndon't require packing so long as they are explicitly identified\ni'll remove the __rte_packed as a part of this series.\n\nv2:\n * app/testpmd, remove packing from simple_gre_hdr\n * net/iavf, remove packing from iavf_ipsec_crypto_pkt_metadata,\n simple_gre_hdr\n * examples, remove packing from pkt_key_qinq, pkt_key_ipv4_5tuple,\n pkt_key_ipv6_5tuple, pkt_key_ipv4_addr, pkt_key_ipv6_addr\n * eal, remove packing from rte_config, __rte_trace_stream_header\n\nTyler Retzlaff (15):\n eal: provide pack start macro for MSVC\n eal: pack structures when building with MSVC\n net: pack structures when building with MSVC\n common/iavf: pack structures when building with MSVC\n common/idpf: pack structures when building with MSVC\n common/mlx5: pack structures when building with MSVC\n dma/ioat: pack structures when building with MSVC\n net/i40e: pack structures when building with MSVC\n net/iavf: pack structures when building with MSVC\n net/ice: pack structures when building with MSVC\n net/mlx5: pack structures when building with MSVC\n net/octeon_ep: pack structures when building with MSVC\n app/testpmd: pack structures when building with MSVC\n app/test: pack structures when building with MSVC\n examples: pack structures when building with MSVC\n\n app/test-pmd/csumonly.c | 2 +-\n app/test/test_efd.c | 1 +\n app/test/test_hash.c | 1 +\n app/test/test_member.c | 1 +\n drivers/common/iavf/iavf_osdep.h | 2 ++\n drivers/common/iavf/virtchnl_inline_ipsec.h | 11 +++++++++++\n drivers/common/idpf/base/idpf_osdep.h | 2 ++\n drivers/common/mlx5/mlx5_common_mr.h | 4 ++++\n drivers/common/mlx5/mlx5_common_utils.h | 1 +\n drivers/common/mlx5/mlx5_prm.h | 28 ++++++++++++++++++++++++++++\n drivers/dma/ioat/ioat_hw_defs.h | 1 +\n drivers/net/i40e/base/i40e_osdep.h | 2 ++\n drivers/net/iavf/iavf_ipsec_crypto.h | 4 +++-\n drivers/net/iavf/iavf_rxtx.c | 2 +-\n drivers/net/ice/base/ice_osdep.h | 2 ++\n drivers/net/mlx5/hws/mlx5dr.h | 1 +\n drivers/net/mlx5/mlx5.h | 1 +\n drivers/net/mlx5/mlx5_flow.h | 5 +++++\n drivers/net/mlx5/mlx5_hws_cnt.h | 1 +\n drivers/net/mlx5/mlx5_utils.h | 4 ++++\n drivers/net/octeon_ep/otx_ep_mbox.h | 1 +\n examples/common/neon/port_group.h | 1 +\n examples/ip_pipeline/cli.c | 10 +++++-----\n examples/ipsec-secgw/ipsec.h | 1 +\n examples/l3fwd-power/main.c | 2 ++\n examples/ptpclient/ptpclient.c | 8 ++++++++\n lib/eal/common/eal_private.h | 2 +-\n lib/eal/include/rte_common.h | 4 +++-\n lib/eal/include/rte_memory.h | 1 +\n lib/eal/include/rte_memzone.h | 1 +\n lib/eal/include/rte_trace_point.h | 2 +-\n lib/eal/x86/include/rte_memcpy.h | 3 +++\n lib/net/rte_arp.h | 2 ++\n lib/net/rte_dtls.h | 1 +\n lib/net/rte_esp.h | 2 ++\n lib/net/rte_ether.h | 1 +\n lib/net/rte_geneve.h | 1 +\n lib/net/rte_gre.h | 4 ++++\n lib/net/rte_gtp.h | 5 +++++\n lib/net/rte_ib.h | 1 +\n lib/net/rte_icmp.h | 3 +++\n lib/net/rte_ip.h | 4 ++++\n lib/net/rte_l2tpv2.h | 4 ++++\n lib/net/rte_macsec.h | 2 ++\n lib/net/rte_mpls.h | 1 +\n lib/net/rte_pdcp_hdr.h | 4 ++++\n lib/net/rte_ppp.h | 1 +\n lib/net/rte_sctp.h | 1 +\n lib/net/rte_tcp.h | 1 +\n lib/net/rte_tls.h | 1 +\n lib/net/rte_udp.h | 1 +\n lib/net/rte_vxlan.h | 2 ++\n 52 files changed, 143 insertions(+), 11 deletions(-)" }
