The first objective of this series is to fix the support of indirect mbufs when the application reserves a private area in mbufs. It also removes the limitation that rte_pktmbuf_clone() is only allowed on direct (non-cloned) mbufs. The series also contains some enhancements and fixes in the mbuf area that makes the implementation of the last patches easier.
Changes in v4: - do not add a priv_size in mbuf structure, having a proper accessor to read it from the pool private area is clearer - prepend some reworks in the mbuf area to simplify the implementation (fix mbuf initialization by not using a hardcoded mbuf size, add accessors for mbuf pool private area, add a helper to create a mbuf pool) Changes in v3: - a mbuf can now attach to another one that have a different private size. In this case, the m->priv_size corresponds to the size of the private area of the direct mbuf. - add comments to reflect these changes - minor style modifications Changes in v2: - do not change the use of MBUF_EXT_MEM() in vhost - change rte_mbuf_from_baddr() to rte_mbuf_from_indirect(), removing one parameter - fix and rework rte_pktmbuf_detach() - move m->priv_size in second mbuf cache line - fix mbuf free in test error case Olivier Matz (12): mbuf: fix mbuf data room size calculation rte_pktmbuf_pool_init examples: always initialize mbuf_pool private area mbuf: add accessors to get data room size and private size mbuf: fix rte_pktmbuf_init when mbuf private size is not zero testpmd: use standard functions to initialize mbufs and mbuf pool mbuf: introduce a new helper to create a mbuf pool apps: use rte_pktmbuf_pool_create to create mbuf pools mbuf: fix clone support when application uses private mbuf data mbuf: allow to clone an indirect mbuf test/mbuf: rename mc variable in m test/mbuf: enhance mbuf refcnt test test/mbuf: verify that cloning a clone works properly app/test-pipeline/init.c | 15 +- app/test-pmd/testpmd.c | 78 +-------- app/test/test_distributor.c | 10 +- app/test/test_distributor_perf.c | 10 +- app/test/test_kni.c | 16 +- app/test/test_link_bonding.c | 10 +- app/test/test_link_bonding_mode4.c | 12 +- app/test/test_mbuf.c | 110 +++++++++--- app/test/test_pmd_perf.c | 11 +- app/test/test_pmd_ring.c | 10 +- app/test/test_reorder.c | 10 +- app/test/test_sched.c | 16 +- app/test/test_table.c | 9 +- app/test/test_table.h | 3 +- doc/guides/rel_notes/updating_apps.rst | 16 ++ examples/bond/main.c | 10 +- examples/distributor/main.c | 11 +- examples/dpdk_qat/main.c | 10 +- examples/exception_path/main.c | 14 +- examples/ip_fragmentation/main.c | 18 +- examples/ip_pipeline/init.c | 28 +-- examples/ipv4_multicast/main.c | 21 +-- examples/kni/main.c | 12 +- examples/l2fwd-ivshmem/host/host.c | 10 +- examples/l2fwd-jobstats/main.c | 10 +- examples/l2fwd/main.c | 11 +- examples/l3fwd-acl/main.c | 11 +- examples/l3fwd-power/main.c | 11 +- examples/l3fwd-vf/main.c | 12 +- examples/l3fwd/main.c | 10 +- examples/link_status_interrupt/main.c | 10 +- examples/load_balancer/init.c | 12 +- examples/load_balancer/main.h | 4 +- .../client_server_mp/mp_server/init.c | 10 +- examples/multi_process/symmetric_mp/main.c | 10 +- examples/netmap_compat/bridge/bridge.c | 12 +- examples/packet_ordering/main.c | 11 +- examples/qos_meter/main.c | 7 +- examples/qos_sched/init.c | 10 +- examples/qos_sched/main.h | 2 +- examples/quota_watermark/include/conf.h | 2 +- examples/quota_watermark/qw/main.c | 7 +- examples/rxtx_callbacks/main.c | 11 +- examples/skeleton/basicfwd.c | 13 +- examples/vhost/main.c | 31 ++-- examples/vhost_xen/main.c | 11 +- examples/vmdq/main.c | 11 +- examples/vmdq_dcb/main.c | 10 +- lib/librte_ether/rte_ethdev.c | 4 +- lib/librte_mbuf/rte_mbuf.c | 63 +++++-- lib/librte_mbuf/rte_mbuf.h | 189 ++++++++++++++++----- lib/librte_pmd_af_packet/rte_eth_af_packet.c | 6 +- lib/librte_pmd_bond/rte_eth_bond_alb.c | 16 +- lib/librte_pmd_e1000/em_rxtx.c | 5 +- lib/librte_pmd_e1000/igb_rxtx.c | 12 +- lib/librte_pmd_fm10k/fm10k_ethdev.c | 6 +- lib/librte_pmd_i40e/i40e_ethdev_vf.c | 6 +- lib/librte_pmd_i40e/i40e_rxtx.c | 15 +- lib/librte_pmd_ixgbe/ixgbe_rxtx.c | 12 +- lib/librte_pmd_pcap/rte_eth_pcap.c | 5 +- lib/librte_pmd_vmxnet3/vmxnet3_rxtx.c | 7 +- 61 files changed, 499 insertions(+), 566 deletions(-) -- 2.1.4
