As discussed in http://www.spinics.net/lists/netdev/msg271497.html If number of IRQs allocated is greater than the number of local NUMA cores, all local cores will be used first, and the rest of the IRQs will be on a remote NUMA node. If no NUMA support - IRQ's and cores will be mapped 1:1 The patch was tested and applied on top of commit 750f679 "Merge branch '6lowpan'" Amir Changes from V1: - Patch 1/2: net: Utility function to get affinity_hint by policy - Fixed error flow to return -EINVAL on error (thanks govind) - Patch 2/2: net/mlx4_en: Use affinity hint - Set ring->affinity_hint to NULL on error Changes from V0: - Fixed small style issues Amir Vadai (1): net: Utility function to get affinity_hint by policy Yuval Atias (1): net/mlx4_en: Use affinity hint drivers/infiniband/hw/mlx4/main.c | 2 +- drivers/net/ethernet/mellanox/mlx4/en_cq.c | 6 ++- drivers/net/ethernet/mellanox/mlx4/en_netdev.c | 30 ++++++++++++++ drivers/net/ethernet/mellanox/mlx4/eq.c | 14 ++++++- drivers/net/ethernet/mellanox/mlx4/mlx4_en.h | 1 + include/linux/mlx4/device.h | 2 +- include/linux/netdevice.h | 3 ++ net/core/dev.c | 56 ++++++++++++++++++++++++++ 8 files changed, 110 insertions(+), 4 deletions(-) -- 1.8.3.4
