2021-10-06RDMA/efa: CQ notificationsGal Pressman1-5/+95
This patch adds support for CQ notifications through the standard verbs api. In order to achieve that, a new event queue (EQ) object is introduced, which is in charge of reporting completion events to the driver. On driver load, EQs are allocated and their affinity is set to a single cpu. When a user app creates a CQ with a completion channel, the completion vector number is converted to a EQ number, which is in charge of reporting the CQ events. In addition, the CQ creation admin command now returns an offset for the CQ doorbell, which is mapped to the userspace provider and is used to arm the CQ when requested by the user. The EQs use a single doorbell (located on the registers BAR), which encodes the EQ number and arm as part of the doorbell value. The EQs are polled by the driver on each new EQE, and arm it when the poll is completed.

The host info feature allows the driver to infrom the EFA device firmware with system configuration for debugging and troubleshooting purposes. The host info buffer is passed as an admin command DMA mapped control buffer, and is unmapped and freed once the command CQE is consumed. Currently, the setting of host info is done for each device on its probe. Failing to set the host info for the device shall not disturb the probe flow, any errors will be discarded.

2019-05-06RDMA/efa: Add EFA device definitionsGal Pressman1-0/+794
EFA PCIe device implements a single Admin Queue (AQ) and Admin Completion Queue (ACQ) pair to initialize and communicate configuration with the device. Through this pair, we run set/get commands for querying and configuring the device, create/modify/destroy queues, and IB specific commands like Address Handler (AH), Memory Registration (MR) and Protection Domains (PD). In addition to admin (AQ/ACQ), we have data path queues that get classified as Queue Pairs (QP) and Completion Queues (CQ).
