[PATCH v2 rdma-next 00/18] Enhance ib_ah_attr to specify types

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch series introduces a typed address handle attribute
that replaces the exisiting IB specific version. One of the 
drawbacks with the existing attibute was the lack of extensibility
when underlying drivers wanted to leverage specific fields in the
attribute structure. This resulted in some of the fields being used
differently than what it was originally intended for.
This patch addresses that drawback by defining three address handle
types namely 'ib', 'roce' and 'opa'. While these these types share most
of the original fields, the changes provide the infrastucture to 
extend and cleanup the fields based on their types. 

Note that these patches apply on the earlier patch series with subject
"[PATCH v2 0/7] Add support for OPA classport info"

Changes from v1:
---------------

* Collected more common fields onto struct rdma_ah_attr.
  ib_ah_attr now has dlid and src_path_bits as its type
  specific attribute. roce_ah_attr has dmac as its type specific
  attribute. opa ah_attr has the 32 bit dlid and src_path_bits as
  its type specfic attribute.
* Rename struct eth_ah_attr to roce_ah_attr
* Rename RDMA_AH_ATTR_TYPE_ETH to RDMA_AH_ATTR_TYPE_ROCE

The patches are organized as follows:
* The first 3 patches perform checkpatch fixes that later patches
  touch upon.
* Patch 4 fixes user verbs ABI to read and write grh fields
  of the address handle only when the appropriate flags are set.
* Patch 5 has a minor fix the soft roce driver in properly initializing
  ah_attr fields during query
* Patch 6 renames struct ib_ah_attr to rdma_ah_attr
* Patch 7 to 10 renames verbs APIs ib_create_ah, ib_query_ah, ib_modify_ah
  and ib_destroy_ah
* Patches 11 to 14 renames some of the internal driver functions
  so they are in sync with the structure rename of patch 5.
* Patch 15 introduces set/get accessor functions to access
  individual elements of the structure
* Patch 16 applies the accessor functions introduced in patch 15
* Patch 17 re-defines rdma_ah_attr to now contain types 'ib' and 'roce'.
  Calling code that uses the attribute are now expected to have
  knowledge of the type.
* Patch 18 defines the 'opa' address handle type. Changes to calling
  code that leverages opa address handle types will be introduced in
  forthcoming patches which enable 32 bit LID support in the kernel.
