Subject: [RFC PATCH 00/16] ib_mad: Add support for Intel Omni-Path Architecture (OPA) MAD processing.
Date: Thu, 13 Nov 2014 14:54:09 -0500 [thread overview]
Message-ID: <1415908465-24392-1-git-send-email-ira.weiny@intel.com> (raw)
The following patch series modifies the kernel MAD processing (ib_mad/ib_umad)
and related interfaces to process Intel Omni-Path Architecture MADs on devices
which support them.
In addition to supporting some IBTA management classes, OPA devices use MADs
with lengths up to 2K. These "jumbo" MADs increase the performance of
management traffic.
To distinguish IBTA MADs from OPA MADs a new Base Version is introduced. The
new format shares the same common header with IBTA MADs which allows us to
share most of the MAD processing code when dealing with the new Base Version.
The patch series is broken into 3 main areas.
1) Add the ability for devices to indicate "jumbo" MAD support. In addition,
modify the ib_mad module to detect those devices and allocate the resources
for the QPs on those devices.
2) Enhance the interface to the device agents to support larger and variable
length MADs.
3) Add support for creating and processing OPA Base Version MADs including
a new SMP class version specific to OPA devices.
