Subject: [rdma 00/16] Intel RDMA Diver Updates 2019-07-03
This patchset adds a unified Intel Ethernet RDMA driver that
supports a new network device E810 (iWARP and RoCEv2 capable)
and the existing X722 iWARP device. The driver architecture
provides the extensibility for future generations of Intel HW
supporting RDMA.
This driver obsoletes legacy X722 driver i40iw which is marked for
deprecation and extends the ABI already defined for i40iw. It is
backward compatible with legacy X722 rdma-core provider (libi40iw).
This series was built against the rdma for-next branch. These changes
are dependent upon changes to i40e and ice driver that are being
submitted to netdev for David Miller's net-next since the LAN drivers in
the RDMA tree are not up-to-date, patch against those drivers would
cause large conflicts with what is currently in Dave's net-next. See
the git tree URL reference for the 3 driver patches which are required
for these changes.
RFC --> v0:
* Rehashed the design to unify RDMA driver. irdma is registered as a
platform driver capable of supporting RDMA capable devices added to
the virtual platform bus by their individual netdev drivers i40e/ice.
Listening to netdev notifiers or running netdev lists are no longer
needed for attachment. There is no load order dependencies between
netdev drivers and irdma in the new model.
MFD architecture was also considered, and we selected the simpler
platform model. Supporting a MFD architecture would require an
additional MFD core driver, individual platform netdev, RDMA function
drivers, and stripping a large portion of the netdev drivers into
MFD core. The sub-devices registered by MFD core for function
drivers are indeed platform devices.
*Use netdev_to_ibdev API to reliably get iwdev in notifiers.
Remove VSI dev list tracking as a result.
*Fixed build make W=1 issues, sparse endianness warnings, 0-day
32-bit compile warnings.
*Test for userspaceness with udata and remove uobject references.
*Remove abstractions for memory allocators, dev_* and pr_* prints.
*Remove redundant castings in the driver.
*Relax barriers to a dma_wmb()/dma_rmb() since we are using coherent
mappings.
*Clang-format run on various portions of the driver.
*Remove internal verb objects tracking from driver as its already done
in IB core.
*Report correct values for max_send_wr and max_recv_wr in irdma_query_qp()
*Check and fail the call for invalid input values on irdma_create_qp().
*ABI fixups - __aligned_u64 on all u64s. Fix travis hit and removed
irdma_hw_attrs struct out of ABI.
*Use IRDMA_RING_MOVE_HEAD_NO_CHECK on cq_ring
*Sort call tables, Kconfig, Makefiles
*Add CQ resize feature and few fixes since RFC was published.
*Use same DRIVER_ID enum for irdma as i40iw.
*Updated ib_copy_from_udata/ib_copy_to_udata calls to do a safe copy()
*Adapt to core handling verb object allocations and other core API changes
*devlink is used to switch between RoCE and iWARP on a per function basis
