Subject: [PATCH for-next 0/4] EFA CQ notifications
Date: Wed, 11 Aug 2021 18:11:27 +0300	[thread overview]
Message-ID: <20210811151131.39138-1-galpress@amazon.com> (raw)

This series adds support for CQ notifications through the verbs api
(ibv_req_notify_cq/ibv_get_cq_event).

In order to achieve that, a new event queue (EQ) object is introduced,
which is in charge of reporting completion events to the driver.

In addition, a new CQ doorbell is introduced that is mmapped to the
userspace provider in order to arm the CQ when requested by the user.

PR was sent:
https://github.com/linux-rdma/rdma-core/pull/1044

Thanks,
Gal
