Cover letter [PATCH rdma-next v1 0/3] Provide more error details when a QP moves to error state
From: Leon Romanovsky <[email protected]>
Changelog:
v1:
* Reworked mlx4 to allow non-atomic IB QP event handler.
v0: https://lore.kernel.org/linux-rdma/[email protected]/
------------------------------------------
The following series adds ability to get information about fatal QP events.
This functionality is extremely useful for the following reasons:
* Provides an information about the reason why QP moved to error state, in cases where CQE isn't generated.
* Allows to provide vendor specfic error codes and information that could be very useful to users who know them.
An example of a case without CQE is a remote write with RKEY violation. In this flow, on remote side no CQEs are generated and such error without indication is hard to debug.
Thanks.
