The size of mlx4_ib_device became too large to be allocated as whole contigous block of memory. Currently it takes about 55K. On architecture with 4K page it means 3rd order. This patch series makes an attempt to split mlx4_ib_device into several parts and allocate them with less expensive kvzalloc Jan Dakinevich (4): IB/core: introduce ->release() callback IB/mlx4: move iboe field aside from mlx4_ib_dev IB/mlx4: move pkeys field aside from mlx4_ib_dev IB/mlx4: move sriov field aside from mlx4_ib_dev drivers/infiniband/core/device.c | 2 + drivers/infiniband/hw/mlx4/alias_GUID.c | 192 ++++++++++++++++---------------- drivers/infiniband/hw/mlx4/cm.c | 32 +++--- drivers/infiniband/hw/mlx4/mad.c | 98 ++++++++-------- drivers/infiniband/hw/mlx4/main.c | 93 ++++++++++------ drivers/infiniband/hw/mlx4/mcg.c | 4 +- drivers/infiniband/hw/mlx4/mlx4_ib.h | 8 +- drivers/infiniband/hw/mlx4/qp.c | 8 +- drivers/infiniband/hw/mlx4/sysfs.c | 40 +++---- include/rdma/ib_verbs.h | 2 + 10 files changed, 256 insertions(+), 223 deletions(-) -- 2.1.4
