* IB/mlx5: Postpone remove_keys under knowledge of coming preemptionLeon Romanovsky2015-12-08
| | | | | | | | | | | | | | | | | | | | | | The remove_keys() logic is performed as garbage collection task. Such task is intended to be run when no other active processes are running. The need_resched() will return TRUE if there are user tasks to be activated in near future. In such case, we don't execute remove_keys() and postpone the garbage collection work to try to run in next cycle, in order to free CPU resources to other tasks. The possible pseudo-code to trigger such scenario: 1. Allocate a lot of MR to fill the cache above the limit. 2. Wait a small amount of time "to calm" the system. 3. Start CPU extensive operations on multi-node cluster. 4. Expect performance degradation during MR cache shrink operation.

ConnectIB has some known issues with memory registration using the local_dma_lkey (SEND, RDMA, RECV seems to work ok). Thus don't expose support for it (remove device->local_dma_lkey setting), and take advantage of the above commit such that no regression is introduced to working systems.

| * net/mlx5e: Fix HW MTU settingsSaeed Mahameed2015-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | Previously we configured HW MTU to be netdev->mtu, actually we need to configure netdev->mtu + (ETH_HLEN + VLAN_HLEN + ETH_FCS_LEN). Also, query MTU can not fail, hence make the relevant helper a void functionm, add mlx5e_set_dev_port_mtu, helper function to handle MTU setting.

| * mlx5: Enable mutual support for IB and EthernetHaggai Abramonvsky2015-06-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ethernet functionality is only available when working in ISSI > 0 mode. Previously, the IB driver wasn't ready to work on that mode, and hence building both the IB driver and the Ethernet functionality in the core driver were disallowed by Kconfigs. Now, once we have all the pre-steps in place, we can remove this limitation. The last steps in the IB driver for getting that setup to work are: create dummy SRQ for the driver's use (until now we could use XRC_SRQ as SRQ and XRC_SRQ, after moving to ISSI > 0, we separate XRC SRQs from basic SRQs) and adapt the create QP function to be compatible with ISSI > 0.

| * net/mlx5: Extend mlx5_core to support ConnectX-4 Ethernet functionalityAmir Vadai2015-05-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the Ethernet part of the driver for the Mellanox ConnectX(R)-4 Single/Dual-Port Adapter supporting 100Gb/s with VPI. The driver extends the existing mlx5 driver with Ethernet functionality. This patch contains the driver entry points but does not include transmit and receive (see the previous patch in the series) routines. It also adds the option MLX5_CORE_EN to Kconfig to enable/disable the Ethernet functionality. Currently, Kconfig is programmed to make Ethernet and Infiniband functionality mutally exclusive. Also changed MLX5_INFINIBAND to be depandant on MLX5_CORE instead of selecting it, since MLX5_CORE could be selected without MLX5_INFINIBAND being selected.

This will be fixed later on. [1] - https://patchwork.ozlabs.org/patch/458531/ CC: David Daney <david.daney@cavium.com> Signed-off-by: Amir Vadai <amirv@mellanox.com> Signed-off-by: David S.

* | IB/mad: Add support for additional MAD info to/from driversIra Weiny2015-06-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to support alternate sized MADs (and variable sized MADs on OPA devices) add in/out MAD size parameters to the process_mad core call. In addition, add an out_mad_pkey_index to communicate the pkey index the driver wishes the MAD stack to use when sending OPA MAD responses. The out MAD size and the out MAD PKey index are required by the MAD stack to generate responses on OPA devices. Furthermore, the in and out MAD parameters are made generic by specifying them as ib_mad_hdr rather than ib_mad. Drivers are modified as needed and are protected by BUG_ON flags if the MAD sizes passed to them is incorrect.
