Date: Sun, 9 Mar 2014 09:39:07 +0200 From: Amir Vadai <amirv@...lanox.com> To: "David S. Miller" <davem@...emloft.net> Cc: netdev@...r.kernel.org, Amir Vadai <amirv@...lanox.com>, Yevgeny Petrilin <yevgenyp@...lanox.com>, Or Gerlitz <ogerlitz@...lanox.com> Subject: [PATCH net-next V4 0/2] net: Affinity hint helper function Hi, This patchset will set affinity hint to influence IRQs to be allocated on the same NUMA node as the one where the card resides. 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 67ddc87: "Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net" Amir Changes from V3: - Patch 2/2: net/mlx4_en: Use affinity hint - somehow patch file was corrupted Changes from V2: - Patch 1/2: net: Utility function to get affinity_hint by policy - Fixed style issues 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 | 57 ++++++++++++++++++++++++++ 8 files changed, 111 insertions(+), 4 deletions(-) -- 1.8.3.1 -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
