[v3,00/17] Memory window support for rdma_rxe

Message

Bob Pearson Aug. 20, 2020, 10:46 p.m. UTC

This set of patches implements the memory windows verbs, local and remote send
operations. Each of these has been tested at a basic level and regressions
tests have been run to see that basic rxe functionality is OK. The rdma-core
pyverbs memory windows test cases run correctly.

I would encourage anyone who has test cases for MWs to run them against
this code and let me know if anything crops up.

There is a matching patch for rdma-core the user space library that is required
to run user space MW applications.

The first two patches clean up checkpatch warnings for the existing rxe source
code. They can be used separately if desired.

The third and fourth patches are a prerequisite for the rest of the set but
are independant and add some WR and WC opcodes to ib_verbs.h and ib_user_verb.h.

The remaining patches implement the memory windows extensions.
