      net/mlx4: Adapt code for N-Port VF · 449fc488
      Matan Barak 提交于
      Adds support for N-Port VFs, this includes:
      1. Adding support in the wrapped FW command
      	In wrapped commands, we need to verify and convert
      	the slave's port into the real physical port.
      	Furthermore, when sending the response back to the slave,
      	a reverse conversion should be made.
      2. Adjusting sqpn for QP1 para-virtualization
      	The slave assumes that sqpn is used for QP1 communication.
      	If the slave is assigned to a port != (first port), we need
      	to adjust the sqpn that will direct its QP1 packets into the
      	correct endpoint.
      3. Adjusting gid[5] to modify the port for raw ethernet
      	In B0 steering, gid[5] contains the port. It needs
      	to be adjusted into the physical port.
      4. Adjusting number of ports in the query / ports caps in the FW commands
      	When a slave queries the hardware, it needs to view only
      	the physical ports it's assigned to.
      5. Adjusting the sched_qp according to the port number
      	The QP port is encoded in the sched_qp, thus in modify_qp we need
      	to encode the correct port in sched_qp.

      net/mlx4_core: Remove unnecessary validation for port number · 6cd28f04
      Moni Shoua 提交于
      This is a fix to a regression introduced by commit:
      "982290a7 net/mlx4_core: Check port number for validity
      before accessing data"
      
      IPoIB could not attach to multicast group and we get this in dmesg:
      [144214.145008] ib0: failed to attach to multicast group, ret = -22
      [144214.145016] ib0: couldn't attach QP to multicast group ff12:401b:ffff:0000:0000:0000:ffff:ffff
      [144214.145019] ib0: multicast join failed for ff12:401b:ffff:0000:0000:0000:ffff:ffff, status -22
      
      The cause to the problem is because port is extracted from gid[5].
      Which is only valid for Ethernet.
      Removed this validation in mlx4_qp_attach_common(), which is accessed
      from both Ethernet and IB flows.
      Error flow for bad port value in Ethernet is already exists in that
      function.

      mlx4_core: Roll back round robin bitmap allocation commit for CQs, SRQs, and MPTs · 7c6d74d2
      Jack Morgenstein 提交于
      Commit f4ec9e95 "mlx4_core: Change bitmap allocator to work in round-robin fashion"
      introduced round-robin allocation (via bitmap) for all resources which allocate
      via a bitmap.
      
      Round robin allocation is desirable for mcgs, counters, pd's, UARs, and xrcds.
      These are simply numbers, with no involvement of ICM memory mapping.
      
      Round robin is required for QPs, since we had a problem with immediate
      reuse of a 24-bit QP number (commit f4ec9e95).
      
      However, for other resources which use the bitmap allocator and involve
      mapping ICM memory -- MPTs, CQs, SRQs -- round-robin is not desirable.
      
      What happens in these cases is the following:
      
      ICM memory is allocated and mapped in chunks of 256K.
      
      Since the resource allocation index goes up monotonically, the allocator
      will eventually require mapping a new chunk. Now, chunks are also unmapped
      when their reference count goes back to zero.  Thus, if a single app is
      running and starts/exits frequently we will have the following situation:
      
      When the app starts, a new chunk must be allocated and mapped.
      
      When the app exits, the chunk reference count goes back to zero, and the
      chunk is unmapped and freed. Therefore, the app must pay the cost of allocation
      and mapping of ICM memory each time it runs (although the price is paid only when
      allocating the initial entry in the new chunk).
      
      For apps which allocate MPTs/SRQs/CQs and which operate as described above,
      this presented a performance problem.
      
      We therefore roll back the round-robin allocator modification for MPTs, CQs, SRQs.
