This patchset is relevant for my NetDev 1.1 "Network Performance BoF" [1].
The first 4 patches, is a repost[2], for the first real use-case of kmem_cache bulk alloc and free API. They were adjusted slightly to accomodate my last slab API changes. They should be ready for inclusion in net-next, as the needed MM tree are avail in net-next. Patch 5 is also enabling the SKB bulk API for mlx5. Thus, patches 1-5 should be ready for net-next. After patch 5, the experimental patches begin, which is Prove-of-Concept code for what we will be discussing during the Network Performance BoF [1] [1] http://netdevconf.org/1.1/bof-network-performance-bof-jesper-dangaard-brouer.html [2] http://thread.gmane.org/gmane.linux.network/384302/ --- Jesper Dangaard Brouer (11): net: bulk free infrastructure for NAPI context, use napi_consume_skb net: bulk free SKBs that were delay free'ed due to IRQ context ixgbe: bulk free SKBs during TX completion cleanup cycle net: bulk alloc and reuse of SKBs in NAPI context mlx5: use napi_*_skb APIs to get bulk alloc and free mlx5: RX bulking or bundling of packets before calling network stack net: introduce napi_alloc_skb_bulk() for more use-cases mlx5: hint the NAPI alloc skb API about the expected bulk size EXPERIMENT: dummy: bulk free net: API for RX handover of multiple SKBs to stack net: RPS bulk enqueue to backlog drivers/net/dummy.c | 3 drivers/net/ethernet/intel/ixgbe/ixgbe_main.c | 6 - drivers/net/ethernet/mellanox/mlx5/core/en.h | 5 - drivers/net/ethernet/mellanox/mlx5/core/en_rx.c | 24 ++- drivers/net/ethernet/mellanox/mlx5/core/en_tx.c | 4 - drivers/net/ethernet/mellanox/mlx5/core/en_txrx.c | 4 - include/linux/netdevice.h | 13 ++ include/linux/skbuff.h | 23 ++- net/core/dev.c | 160 ++++++++++++++++++++- net/core/skbuff.c | 122 +++++++++++++++- 10 files changed, 327 insertions(+), 37 deletions(-) --
