The following patch series adds the OPA device driver. Like qib the driver has 2 main interfaces, Verbs and a new PSM2 interface. The PSM2 interface evolves PSM for OPA due to hardware specific changes. As a verbs driver the device functions as an InfiniBand device and supports the standard features of the IBTA specification v1.3 with the exceptions noted below. Addressing is accomplished via IBTA compatible headers which leaves Path Record resolution, rdmacm, and IB CM functionality intact. Furthermore, the interaction between this driver and the ib_core, rdmacm, ib_cm, ib_sa, and ULP modules are handled completely via the existing verbs interfaces. This includes compliance with the IB SA queries (most importantly Path Records and Multicast Joins) and CM protocols which are documented in the IBTA spec. The following exceptions to the IBTA specification exist: Enhanced and additional SMA and PMA MADs are utilized for management. As previously discussed on the list and accepted by Doug; device support for these new MADs is reported through the new immutable data interface. Larger MTU values can _optionally_ be passed through the verbs interface to indicate 8K and "10K" MTUs. This is opaque to users of Path Record queries. More importantly the _standard_ IBTA MTUs are fully supported. A larger packet sequence number is used internally by the driver. Additional QoS features, which are opaque to the user, are supported via additional SL to VL tables. The public information can be reviewed at: http://www.intel.com/content/www/us/en/omni-path/omni-path-fabric-overview.html The patches are based on the the following repo/branch: git://github.com/dledford/linux.git: to-be-rebased/for-4.3 The patches add the files and headers and the last patch adds the build hooks. Differences from v3 - Get rid of BUG_ON() usage - 125 internal fixes - Removed some more unneeded sysfs files - Add documentation on sysfs usage - ported from qib o commit d1adbfa5dd58642cde08f2f7773f37b6fafc7b64 o commit 83efc96cd2dbb42971831dda007b521cf6d92ac5 Differences from v2 to v3: - Remove verbs sysfs counters since they can be metered via other mechanisms - Move ib-ish defintions from mad.h to ib_mad.h since they are driver independent - Modified create_cq to better implements the API changes Differences from v1 to v2: - larger files split are split up due to filesize issues - 0 day build issues with cpumask usage - 0 day RCU sparse issues - Adjustments for create_cq() and query_device() to compile --- Dennis Dalessandro (1): IB: Add CNP opcode enumeration.
