Cover letter [PATCH 0/5] IB/hfi1: sdma engine affinity improvements
This patch series is a set of performance improvements that deal with handling the affinity of sdma engines. This allows users more control over which CPU cores are used by the driver for sdma engines. It includes a way to dump out the current values and a handler for when the user changes irq affinity. The changes to sysfs are also documented.
This applies on top of the last series submitted and can be seen in my GitHub:
