From de1618034ae5704f9e503a20a1c328a0e60f6b5f Mon Sep 17 00:00:00 2001 From: Ido Shamay Date: Sun, 31 May 2015 09:30:17 +0300 Subject: net/mlx4_core: Move affinity hints to mlx4_core ownership Now that EQs management is in the sole responsibility of mlx4_core, the IRQ affinity hints configuration should be in its hands as well. request_irq is called only once by the first consumer (maybe mlx4_ib), so mlx4_en passes the affinity mask too late. We also need to request vectors according to the cores we want to run on. mlx4_core distribution of IRQs to cores is straight forward, EQ(i)->IRQ will set affinity hint to core i. Consumers need to request EQ vectors, according to their cores considerations (NUMA). Signed-off-by: Ido Shamay Signed-off-by: Matan Barak Signed-off-by: Or Gerlitz Signed-off-by: David S.
