An application can connect to any of the queue managers within the queue sharing group. Because all the queue managers in the queue sharing group can access all the shared queues, the application does not depend on the availability of a specific queue manager; any queue manager in the queue ...
全称为Shared Receive Queue,直译为共享接收队列。我们知道,RDMA通信的基本单位是QP,每个QP都由一个发送队列SQ和接收队列RQ组成。 SRQ是IB协议为了给接收端节省资源而设计的。我们可以把一个RQ共享给所有关联的QP使用,这个公用的RQ就称为SRQ。当与其关联的QP想要下发接收WQE时,都填写到这个SRQ中。然后每当硬件接收到...
The queue system uses the common buffer which receives the input data from multiple entries, allocates the memory device inside the common buffer to the occasion where the entry stream supplies those input data to the aforementioned input data stream. In order from the multiple entry common ...
To minimize the memory and overhead associated with maintaining a mapping of each data-item, memory locations that are allocated to each input-stream are maintained in a sequential, first-in, first-out queue. When a subsequent receiving device acknowledges that it is ready to receive a data-...

I'm looking for a fast and efficient way for user-space to send I/O to my driver. One way I'd have hoped to do this, was through a shared memory ring-buffer. In the WWDC19 presentation on System Extensions and DriverKit, at roughly 17:00, they mention an IOSharedDataQueueDispatch...
