Roland, The enclosed patch series enhances the IBoE kernel stack to use GID change event and network flow counters.
This work is based on earlier patches done by Eli Cohen <e...@mellanox.co.il> posted during Nov/2010 see http://marc.info/?l=linux-rdma&m=128939180605962 The first change is used to avoid using the irrelevant LID change event for updating the IB core GID cache, and is made of two patches: [PATCH 1/9] ib/core: Add GID change event [PATCH 2/9] ib/mlx4: use GID change event on IBoE code The second change is used such that eventually we're able to implement port level packets/bytes performance counters for IBoE and is made of seven patches: [PATCH 3/9] mlx4: extend cap flags to 64 bit [PATCH 4/9] mlx4: align current extended capabilities to use the flags field [PATCH 5/9] mlx4: Fix layout of QP context for correct location of counter index [PATCH 6/9] mlx4: add network flow counters [PATCH 7/9] ib/pma: add include file for IBA performance counters definitions [PATCH 8/9] ib/mlx4: use flow counters on IBoE ports [PATCH 9/9] ib/mlx4: support PMA counters for IBoE patches #3 and #4 change the mlx4 driver such that it now uses a 64 bit capability flags. This extended cap flags field is used to account for currently implemented extended capabilities (e.g udp_rss, uc/mc vep steering, etc) and for the flow counters capability. These two patches are light in the sense that they don't add/remove any functionality from the driver. patch #5 is a bug fix for driver view of the mlx4 QP context layout w.r.t to the counter index location. patch #6 adds mlx4 support for network flow counters, where such counter can be pointed by a set containing one or more QPs and track receive and transmit packets and bytes of these QPs. patch #7 moves the various definitions and mad structures related to IBA PM agent from the ipath and qib drivers into a single include file, so we can later use them for IBoE and avoid the current code duplication... patches #8 and #9 bring the actual IBoE use of the counters, done through allocating flow counter per Ethernet/IBoE port, such that this counter is later pointed by all mlx4_ib QPs created on that port. Later this counter can be queried so get a port level packets/bytes performance counters ala IB Or. drivers/infiniband/core/cache.c | 3 drivers/infiniband/hw/ipath/ipath_mad.c | 134 ------------------------ drivers/infiniband/hw/mlx4/mad.c | 68 ++++++++++++ drivers/infiniband/hw/mlx4/main.c | 22 +++- drivers/infiniband/hw/mlx4/mlx4_ib.h | 1 drivers/infiniband/hw/mlx4/qp.c | 10 + drivers/infiniband/hw/qib/qib_mad.h | 176 -------------------------------- drivers/net/mlx4/en_ethtool.c | 9 - drivers/net/mlx4/en_main.c | 3 drivers/net/mlx4/en_netdev.c | 5 drivers/net/mlx4/en_port.c | 6 - drivers/net/mlx4/en_selftest.c | 3 drivers/net/mlx4/fw.c | 39 ++++--- drivers/net/mlx4/fw.h | 8 - drivers/net/mlx4/main.c | 62 ++++++++++- drivers/net/mlx4/mcg.c | 17 +-- drivers/net/mlx4/mlx4.h | 1 drivers/net/mlx4/port.c | 8 - include/linux/mlx4/cmd.h | 3 include/linux/mlx4/device.h | 60 ++++++---- include/linux/mlx4/qp.h | 8 - include/rdma/ib_verbs.h | 3 22 files changed, 262 insertions(+), 387 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
