2018-09-26RDMA: Fully setup the device name in ib_register_deviceJason Gunthorpe1-2/+1
The current code has two copies of the device name, ibdev->dev and dev_name(&ibdev->dev), and they are setup at different times, which is very confusing. Set them both up at the same time and make dev_name() the lead name, which is the proper use of the driver core APIs. To make it very clear that the name is not valid until registration pass it in to the ib_register_device() call rather than messing with ibdev->name directly. Also the reorganization now checks that dev_name is unique even if it does not contain a %.

2018-06-18IB/core: add max_send_sge and max_recv_sge attributesSteve Wise1-1/+2
This patch replaces the ib_device_attr.max_sge with max_send_sge and max_recv_sge. It allows ulps to take advantage of devices that have very different send and recv sge depths. For example cxgb4 has a max_recv_sge of 4, yet a max_send_sge of 16. Splitting out these attributes allows much more efficient use of the SQ for cxgb4 with ulps that use the RDMA_RW API. Consider a large RDMA WRITE that has 16 scattergather entries. With max_sge of 4, the ulp would send 4 WRITE WRs, but with max_sge of 16, it can be done with 1 WRITE WR.

2017-08-10RDMA: Simplify get firmware interfaceLeon Romanovsky1-3/+2
There is a need to forward FW version to user space application through RDMA netlink. In order to make it safe, there is need to declare nla_policy and limit the size of FW string. The new define IB_FW_VERSION_NAME_MAX will limit the size of FW version string. That define was chosen to be equal to ETHTOOL_FWVERS_LEN, because many drivers anyway are limited by that value indirectly. The introduction of this define allows us to remove the string size from get_fw_str function signature. Signed-off-by: Leon Romanovsky <leonro@mellanox.com>

2017-02-14IB: Query ports via the core instead of direct into the driverOr Gerlitz1-3/+4
Change the drivers to call ib_query_port in their get port immutable handler instead of their own query port handler. Doing this required to set the core cap flags of this device before the ib_query_port call is made, since the IB core might need these caps to serve the port query. Drivers are ensured by the IB core that the port attributes passed to the port query verb implementation are zero, and hence we removed the zeroing from the drivers.

2016-05-26IB/core: Make device counter infrastructure dynamicChristoph Lameter1-43/+104
In practice, each RDMA device has a unique set of counters that the hardware implements. Having a central set of counters that they must all adhere to is limiting and causes many useful counters to not be available. Therefore we create a dynamic counter registration infrastructure. The driver must implement a stats structure allocation routine, in which the driver must place the directory name it wants, a list of names for all of the counters, an array of u64 counters themselves, plus a few generic configuration options. We then implement a core routine to create a sysfs file for each of the named stats elements, and a core routine to retrieve the stats when any of the sysfs attribute files are read. To avoid excessive beating on the stats generation routine in the drivers, the core code also caches the stats for a short period of time so that someone attempting to read all of the stats in a given device's directory will not result in a stats generation call per file read. Future work will attempt to standardize just the shared stats elements, and possibly add a method to get the stats via netlink in addition to sysfs.

2015-10-28RDMA/cxgb3: Support the new memory registration APISagi Grimberg1-0/+33
Support the new memory registration API by allocating a private page list array in iwch_mr and populate it when iwch_map_mr_sg is invoked. Also, support IB_WR_REG_MR by duplicating build_fastreg just take the needed information from different places: - page_size, iova, length (ib_mr) - page array (iwch_mr) - key, access flags (ib_reg_wr) The IB_WR_FAST_REG_MR handlers will be removed later when all the ULPs will be converted.

2015-07-24RDMA/cxgb3: fail get_dma_mr on 64 bit archesSteve Wise1-0/+4
T3 HW only supports 32 bit MRs. If the system uses 64 bit memory addresses, then a registered 32 bit MR will wrap and write to the wrong memory when used with addresses > 4GB. To prevent this, simply fail to allocate an MR on 64 bit machines (other means of registering memory are still available and software can still work, we just don't allow this means of memory registration).

2015-06-12IB/mad: Add support for additional MAD info to/from driversIra Weiny1-1/+5
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.
