      mlx4_core: Use MOD_STAT_CFG command to get minimal page size · 2d928651
      Vladimir Sokolovsky 提交于
      There was a bug in some versions of the mlx4 driver in
      mlx4_alloc_fmr(), which hardcoded the minimum acceptable page_shift to
      be 12.  However, new ConnectX firmware can support a minimum
      page_shift of 9 (log_pg_sz of 9 returned by QUERY_DEV_LIM) -- so with
      old drivers, ib_fmr_alloc() would fail for ULPs using the device
      minimum when creating FMRs.
      
      To preserve firmware compatibility with released mlx4 drivers, the
      firmware will continue to return 12 as before for log_page_sz in
      QUERY_DEV_CAP for these drivers.  However, to enable new drivers to
      take advantage of the available smaller page size, the mlx4 driver now
      first sets the log_pg_sz to the device minimum by setting a
      log_page_sz value to 0 via the MOD_STAT_CFG command and then reading
      the real minimum via QUERY_DEV_CAP.

      IB/mlx4: Handle FW command interface rev 3 · 5ae2a7a8
      Roland Dreier 提交于
      Upcoming firmware introduces command interface revision 3, which
      changes the way port capabilities are queried and set.  Update the
      driver to handle both the new and old command interfaces by adding a
      new MLX4_FLAG_OLD_PORT_CMDS that it is set after querying the firmware
      interface revision and then using the correct interface based on the
      setting of the flag.

      IB/mlx4: Add a driver Mellanox ConnectX InfiniBand adapters · 225c7b1f
      Roland Dreier 提交于
      Add an InfiniBand driver for Mellanox ConnectX adapters.  Because
      these adapters can also be used as ethernet NICs and Fibre Channel 
      HBAs, the driver is split into two modules: 
       
        mlx4_core: Handles low-level things like device initialization and 
          processing firmware commands.  Also controls resource allocation 
          so that the InfiniBand, ethernet and FC functions can share a 
          device without stepping on each other. 
       
        mlx4_ib: Handles InfiniBand-specific things; plugs into the 
          InfiniBand midlayer.
