[PATCH rdma-core 0/9] Add thread domain support

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

 



This series enables grouping verbs objects together for the purpose of
optimizing the behavior of the driver in a multi-threaded environment.

The first use of this will be for mlx5 to group UAR registers in a way that
avoids needing locking on the post send path.

The series follows an RFC and a detailed discussion over it in the ML, the
matching kernel side was sent to rdma-next for 4.16.

A detailed description of the API and its usage appears as part of the man
pages and the commit logs which are part of the series.
