John Kacur 2014-01-23 20:46:30 UTC Doc Text Cause: Various aspects of cache on Infiband, sometimes due to upstream infrastructure changes resulted in potentially bad performance.

Consequence: Poor cache performance on InfiniBand

Fix: 1. Only cache valid GIDs and not empty ones to reduce search time. 2. When searching GIDs on a list of devices, first start with the device that received the request. 3. Change cma_acquire_dev function to search for cached GIDs.

Result: Improved IB performance, potentially pathological (for throughput performance) code paths removed.
